The present invention relates to a data storage library for the storage and data transfer of data storage media, and more specifically, to a data storage library having one or more library frames having an extension or barrier substantially surrounding at least an access opening of the one or more library frames.
Automated data storage libraries are known for providing cost effective storage and retrieval of large quantities of data. The data in automated data storage libraries is typically stored on media of data storage cartridges that are, in turn, stored at storage slots or the like inside the library in a fashion that renders the media, and its resident data, accessible for physical retrieval. Such data storage cartridges are commonly termed “removable media.” Data storage cartridge media may comprise any type of media on which data may be stored and which may serve as removable media, including but not limited to magnetic media (such as magnetic tape or disks), optical media (such as optical tape or disks), electronic media (such as PROM, EEPROM, flash PROM, COMPACTFLASH™, SMARTMEDIA™, MEMORY STICK™, etc.), or other suitable media. An example of a data storage cartridge that is widely employed in automated data storage libraries for mass data storage is a magnetic tape cartridge.
In addition to data storage media, automated data storage libraries typically comprise data storage drives that store data to, and/or retrieve data from, the data storage cartridge media. Further, automated data storage libraries typically comprise I/O stations at which data storage cartridges are supplied or added to, or removed from, the library. The transport of data storage cartridges between data storage slots, data storage drives, and I/O stations is typically accomplished by one or more robotic accessors. Such accessors have grippers for physically retrieving the selected data storage cartridges from the storage slots within the automated data storage library and transporting such cartridges to the data storage drives by moving, for example, in the horizontal (X) and vertical (Y) directions.
In an effort to increase storage capacity, deep slot technology allows for storage cells that contain more than a single data storage cartridge. Such storage libraries allow for higher density, or more cartridges stored per square foot. In “deep slot” libraries, two or more cartridges may be stored in a multi-cartridge deep slot cell, arrayed in series, one behind the other, in tiers ranging from a front-most tier to a rearmost tier.
In accordance with an aspect of the disclosure, a barrier configured to at least partially surround at least one access opening that permits access to an interior of a data storage library through at least one access door is disclosed. The barrier includes at least one side surface configured to be coupled to the at least one door at least partially along a first side surface location and to the data storage library along a second side surface location, and at least one top surface configured to be coupled to the at least one door at least partially along a first top surface location and to the data storage library along a second top surface location. The at least one side surface and the at least one top surface of the barrier system may be configured to be deployable to surround the at least one access opening and form a working space when the at least one door is in an open position, and are configurable to be collapsible when the at least one door is in a closed position. The at least one side surface and the at least one top surface may be configured to resist environmental conditions external to the data storage library from intruding into the working space when the at least one side surface and the at least one top surface are deployed.
In accordance with another aspect of the disclosure, a barrier configured to at least partially surround at least one access opening that permits access to an interior of a data storage library, the at least one access opening having at least one door, is disclosed. The barrier includes at least one side surface configured to be coupled to the at least one door at a first side surface location and to the data storage library at a second side surface location, wherein a barrier storage mechanism is configured to be coupled to at least one of the data storage library and the at least one door at a location adjacent the at least one access opening and opposite a hinged connection location of the at least one door. The at least one side surface of the barrier system is configured to automatically deploy when the at least one door is opened and is configured to automatically retract when the at least one door is closed, and the at least one side surface of the barrier system is configured to resist environmental conditions from exterior the data storage library from intruding into the interior of data storage library when the at least one side surface is deployed.
According to another aspect of the disclosure, a system is disclosed which includes a data storage library, wherein the data storage library is configured to read and receive media associated with one or more data storage cartridges, and further wherein the data storage library comprises at least one access opening for servicing an interior of the data storage library having at least one access door for access through the at least one access opening. The system also includes at least one environmental conditioning unit configured to control at least one environmental condition within the data storage library, as well as at least one barrier configured to automatically deploy and surround the at least one access opening of the data storage library when the at least one access door is opened, and further wherein the barrier is configured to resist environmental conditions external to the data storage library from intruding into the interior of the data storage library when the at least one access door is opened.
The following description is made for the purpose of illustrating the general principles of the present invention and is not meant to limit the inventive concepts claimed herein. Further, particular features described herein can be used in combination with other described features in each of the various possible combinations and permutations.
Unless otherwise specifically defined herein, all terms are to be given their broadest possible interpretation including meanings implied from the specification as well as meanings understood by those skilled in the art and/or as defined in dictionaries, treatises, etc.
It must also be noted that, as used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless otherwise specified.
Efforts to improve the performance of traditional data centers attempt to minimize the cost of processing and storing data. One option that is employed to reduce operational costs of datacenters is to run the equipment in the datacenter at the high end of its environmental operational limits, thereby allowing for cooling of the datacenter to be reduced. In other words, datacenters are running increasingly hot and more humid conditions than traditional datacenters in an attempt to reduce operating costs. Although this strategy may be effective when applied to disk and/or flash data storage environments, magnetic tape is more susceptible to degradation when exposed to these unfavorable conditions. Therefore, this option is not available for magnetic tape libraries.
In an effort to control the environment within magnetic tape libraries so as to provide suitable working conditions for magnetic tape media, data storage drives, etc., air conditioning units may be incorporated into the data storage libraries themselves. While these air conditioning units effectively control the temperature and humidity within the data storage libraries, the environmental conditions of the area surrounding the data storage libraries remain largely unchanged, with conditions often being higher in both temperature and humidity. While this may allow a datacenter to operate at reduced costs, it may also result in a marked temperature differential between the interior and exterior environments of the data storage libraries. Such a temperature differential may prove problematic during service of the data storage library and/or replacement of data storage library components such as data storage cartridges, data storage drives, etc., as condensation may develop on replacement cartridges and other service parts during installation and/or removal from the data storage library. Condensation accumulation on such sensitive componentry may cause component failure and/or data loss. Herein, service, service access or service procedure of the data storage library refers to maintenance, repair, adding data storage cartridges, removing data storage cartridges, or any other reason that access to the interior of the data storage library may be required.

As illustrated, the storage frame 11 may optionally include an operator panel or other user interface, such as a web-based interface, which allows a user to interact with the library 10. Optionally, the library 10 may have an associated software application having a user interface, which also allows a user to interact with the library 10. The software application may be executable on a computing device, a remote server, a cloud or a mobile device.

In one approach, the library is controlled, not by a central controller, but rather, by a distributed control system for receiving logical commands and converting the commands to physical movements of the accessor and gripper, and for operating the drives in accordance with the desired physical movements. The distributed control system may also provide logistical support, such as responding to host requests for element status, inventory, library status, etc. The specific commands, the conversion of those commands to physical movements of the accessor, gripper, controllers, and other components, and the operation of the drives may be of a type known to those of skill in the art.
While the automated data storage library 10 has been described as employing a distributed control system, various other approaches described and/or suggested herein may be implemented in automated data storage libraries regardless of control configuration, such as, but not limited to, an automated data storage library having one or more library controllers that are not distributed.
With continued reference to
According to one embodiment, the library 10 may be controlled by a library controller. Moreover, in various approaches, the library controller may include a distributed control system receiving the logical commands from hosts, determining the required actions, and/or converting the actions to physical movements of the first and/or second accessors 18, 28 and/or gripper assemblies 20, 30. In another approach, the distributed control system may have a plurality of processor nodes, each having one or more computer processors. According to one example of a distributed control system, a communication processor node 50 may be located in a storage frame 11. The communication processor node provides a communication link for receiving the host commands, either directly or through the drives 15, via at least one external interface, e.g., coupled to line 80.
As illustrated in
According to some approaches, the data storage drives 15 may be in close proximity to the communication processor node 50, and may employ a short distance communication scheme, such as Ethernet, or a serial connection, such as RS-422. Thus, the data storage drives 15 may be individually coupled to the communication processor node 50 by lines 70. Alternatively, the data storage drives 15 may be coupled to the communication processor node 50 through one or more networks.
Furthermore, additional storage frames 11 may be provided, whereby each is preferably coupled to the adjacent storage frame. According to various approaches, any of the additional storage frames 11 may include communication processor nodes 50, storage slots 16, storage cells 100, data storage drives 15, networks 60, etc.
An automated data storage library 10 typically comprises one or more controllers to direct the operation of the automated data storage library. Moreover, host computers and data storage drives typically include similar controllers. A library controller may take many different forms and may comprise, for example, but is not limited to, an embedded system, a distributed control system, a personal computer, a workstation, etc. The term “library controller” as used herein is intended in its broadest sense as a device that includes at least one processor, and optionally further circuitry and/or logic, for controlling and/or providing at least some aspects of library operations.

According to various approaches, the nonvolatile memory 404 may comprise any type of nonvolatile memory such as, but not limited to, Electrically Erasable Programmable Read Only Memory (EEPROM), flash Programmable Read Only Memory (PROM), battery backup RAM, hard disk drives, etc. However, the nonvolatile memory 404 is typically used to hold the executable firmware and any nonvolatile data containing programming instructions that can be executed to cause the processor 402 to perform certain functions.
In some embodiments, the I/O interface 405 may include a communication interface that allows the processor 402 to communicate with devices external to the controller. Examples of the communication interface may comprise, but are not limited to, serial interfaces such as RS-232, USB (Universal Serial Bus), Small Computer Systems Interface (SCSI), RS-422 or a wireless communication interface such as Wi-Fi, Bluetooth, near-field communication (NFC) or other wireless interfaces. The controller 400 may communicate with an external device via the communication interface 405 in any communication protocols such as Automation/Drive Interface (ADI).
The device specific circuits 401 provide additional hardware to enable the controller 400 to perform unique functions including, but not limited to, motor control of an accessor cartridge gripper. Moreover, the device specific circuits 401 may include electronics that provide, by way of example but not limitation, Pulse Width Modulation (PWM) control, Analog to Digital Conversion (ADC), Digital to Analog Conversion (DAC), etc. In addition, all or part of the device specific circuits 401 may reside outside the controller 400.
While the automated data storage library 10 is described as employing a distributed control system, the various approaches described and/or suggested herein may be implemented in various automated data storage libraries regardless of control configuration, including, but not limited to, an automated data storage library having one or more library controllers that are not distributed. Moreover, a library controller may comprise one or more dedicated controllers of a library, depending on the desired embodiment. For example, there may be a primary controller and a backup controller. In addition, a library controller may comprise one or more processor nodes of a distributed control system. According to one example, communication processor node 50 (e.g., of

System 1000 further includes an optional environmental conditioning unit 1012 associated with the frame 1002. The environmental conditioning unit 1012 may be integrated with and coupled to frame 1002. For the purposes of the present disclosure, it is to be understood that an environmental conditioning unit may be any device which conditions the air and/or the surrounding environment and is able to change the environmental conditions. The environmental conditions may include (but are not limited to) temperature, humidity, pressure, etc. In one embodiment, the environmental conditioning unit may be an air-conditioning unit. In other embodiments, the environmental conditioning unit may be a thermo-electric heater, a thermo-electric cooler, an electric heater, a liquid heater, a liquid cooler, a heat pump, an evaporative cooler, an ionizer, a de-ionizer, a humidifier, a dehumidifier, one or more fans, or any combination thereof. An environmental conditioning unit in accordance with one embodiment of the present disclosure may increase or decrease the temperature, humidity, pressure, etc. The environmental conditioning unit 1012 may be coupled to an upper surface 1014 (e.g., the roof) of the frame 1002 as shown in
The environmental conditioning unit 1012 is preferably configured such that it may adjust, change and/or regulate the relative conditions (e.g., temperature, humidity, contaminant presence via filtering, etc.) inside the frame 1002. Thus, according to different approaches, the environmental conditioning unit may be able to reduce the temperature of the interior of the frame 1002 and/or reduce the relative humidity of the interior of the frame 1002, depending on the type of environmental conditioning unit 1012 employed. The environmental conditioning unit 1012 is preferably configured to turn on and off as desired to maintain a selected temperature and/or humidity in the interior of the frame 1002. Alternatively, the environmental conditioning unit may have a fan and the fan can be left always on to keep air circulating within the interior of the frame. In one embodiment, the environmental conditioning unit may be an air conditioning unit and the fan may be continuously on and the condenser may turn on and off to maintain a selected temperature and/or humidity in the interior of the frame 1002.
As would be appreciated by one skilled in the art, the environmental conditioning unit 1012 may be an air conditioning unit and may be able to adjust the relative temperature and/or humidity of the interior of the frame 1002 in a conventional manner. Cold air may flow into the interior of the frame 1002 via an inlet air duct 1030 which may connect the environmental conditioning unit 1012 to the interior of the frame 1002, and form an inlet 1035 in the upper surface 1014 of the frame 1002. Specifically, an inlet air duct 1030 may direct the air cooled by the environmental conditioning unit 1012 into the interior of the frame 1002, e.g., where the majority of the data storage media may be stored. As a result, air flow is created from the environmental conditioning unit 1012 to the interior of the frame 1002, as indicated by arrows 1024. This air flow may be induced by a fan included in the air conditioning unit 1012 and/or by using the fans in the one or more tape drives 1006 in the frame 1002. Although the air flow is preferably directed from the environmental conditioning unit 1012 to the interior of the frame 1002, and from the interior of the frame 1002 back to the environmental conditioning unit 1012, the particular path that the air flow is shown as extending along in the present embodiment by arrows 1024 is in no way intended to limit the disclosure or the invention.

In one embodiment, any vents, voids, seams, etc. in the frame 1002 of the library 1004, other than inlet 1035 and an outlet 1032 in an upper surface 1014 of the frame 1002, are preferably sealed such that air from outside the frame 1002 is restricted from entering the interior thereof. The frame 1002 may be sealed using any processes which would be apparent to one skilled in the art upon reading the present description, e.g., including but not limited to inserting foam, implementing insulating seals, etc. New frames may be built without any vents, voids, seams, etc. The housing and panels enclosing the frame 1002 may also be insulated to prevent or inhibit unconditioned air from entering the frame 1002.
The frame 1002 may also include one or more environmental sensors 1050 exterior to the library 1004 and may also include one or more sensors 1055 exterior to the library 1004 but inside the enclosure 1020 for the environmental conditioning unit 1012. In one embodiment the sensors 1055 may be located in front of inlet 1022 of the environmental conditioning unit 1012. The environmental sensors 1050, 1055 may be any sensor appropriate for determining the environmental conditions at the sensor location, such as one or more temperature sensors, one or more humidity sensors, one or more pressure sensors, etc. The one or more environmental sensors 1050, 1055 may be in communication with a library controller, such as library controller 400 shown and described with respect to

While a data storage library having an associated and/or integrated environmental conditioning unit advantageously controls the environmental conditions within the library, some challenges may exist when components within such a data storage library need to be serviced or replaced. As noted above, many data centers are now maintained at higher temperatures and higher humidity levels to reduce the costs relating to cooling the environment where the data storage library is located, e.g., the data center. For this reason, environmental conditions of the data center may be substantially different from those within a data storage library having an associated environmental conditioning unit which controls the environmental conditions within the data storage library. As such, opening an access door to the data storage library may introduce an influx of air from the data center into the conditioned environment of the data storage library, potentially causing and/or resulting in undesirable conditions (e.g., the formation and/or accumulation of condensation on various surfaces) within the data storage library. For example, moisture accumulation on surfaces of sensitive components such as data storage cartridges and data storage drives is undesirable, as condensation potentially may lead to equipment damage, up to and including failure of the components and/or data loss.
Thus, in accordance with aspects of the disclosure, an apparatus, for example a movable barrier, is provided that may be configured, arranged, and transformable to at least partially surround an access opening of a data storage library. The data storage library may comprise an associated environmental conditioning unit (e.g., an air conditioning unit). The barrier may permit an access door or other access panel of the data storage library to be opened in a manner that inhibits, impedes, resists, and/or prevents an influx of air from the surrounding data center into the interior of the data storage library. Thus, the barrier may resist, impede, inhibit, and/or prevent contaminants (e.g., dust, dirt, smoke, ash, etc.), thermal shock and/or condensation formation and/or accumulation on sensitive componentry during service and/or maintenance procedures due to wide variations in environmental conditions between the interior of the data storage library and the exterior of the data storage library, e.g. the data center.
Referring to
As noted above, service access system 2000 comprises a barrier 2001 adapted and configured to substantially and/or entirely surround the access opening of data storage library frame(s) 1002, which preferably permits access to the data storage library in a manner that separates, insulates, and/or isolates environmental conditions from exterior of the data storage library from intruding the data storage library during access (e.g., to insert or remove media, for a service and/or maintenance procedure, etc.) while also providing an accessible work space when door 1065 is opened. As shown in
Barrier 2001 further includes a top portion 2006 and bottom skirt portion 2008. Top portion 2006 and bottom skirt portion 2008 may be formed of the same material as sidewall portion 2002. However, even if sidewall portion 2002 is formed of a flexible material, one or both of top portion 2006 and bottom skirt portion 2008 may be formed of a more rigid material, as there may be additional space above and below library frame 1002 for storage of such rigid structures, as will be further detailed below.
One side of sidewall portion 2002 may be coupled to the unhinged open end of door 1065, while the other side of sidewall portion 2002 may be coupled to a retracting barrier storage mechanism 2005, which may be affixed at or near the side frame portion 1070 of frame 1002. Barrier storage mechanism 2005 may operate similar to a retractable window shade mechanism, wherein the sidewall portion 2002 of barrier 2001 may be compactly rolled within barrier storage mechanism 2005 when door 1065 is closed. However, when door 1065 is opened, sidewall portion 2002 may be extended and/or deployed from barrier storage mechanism 2005 so as to form a work space and/or chamber in the area between sidewall portion 2002 and the access opening of library frame 1002, thereby increasing the volumetric space inside the barrier system enclosure to work on the data storage library while protecting the library's interior environment. While barrier storage mechanism 2005 is shown as mounted at or near the side frame portion 1070 of single frame 1002, it is to be understood that barrier storage mechanism 2005 may be mounted elsewhere on the data storage library. For example, if frame 1002 is not a single frame or an end frame in a multi-frame data storage library, barrier store mechanism 2005 may be located between adjacent frames in the multi-frame data storage library. In another example, barrier store mechanism 2005 may be located at door 1065 or there may not be a barrier store mechanism 2005. Herein, barrier store, barrier store mechanism, and barrier storage mechanism may all refer to the same component or mechanism.
Bottom skirt portion 2008, which extends along the bottom portion of barrier 2001, may aid in preventing air from entering or escaping in the gap formed between the sidewall portion 2002 and the floor of the room (e.g., the data center) when door 1065 is opened. In one aspect, bottom skirt portion 2008 may be formed of a rigid or semi-rigid material and may slide below frame 1002 (i.e., in gap 1071 shown in
In addition to bottom skirt portion 2008, a door sweep or door skirt 1073 may be attached along the length of bottom frame portion 1066 of door 1065. Similar to bottom skirt portion 2008, door skirt 1073 may aid in preventing air from entering or escaping below a gap between bottom frame portion 1066 and the floor. Door skirt 1073 may be formed of any appropriate material, including flexible, semi-rigid, or rigid materials. Herein, door skirt 1073 may comprise anything that provides a partial or full environmental seal between the bottom of a door 1065 and the floor upon which the library rests (e.g., a skirt, door sweep, hanging flap(s), hanging slot(s), air curtain, etc.). Furthermore, while not shown, a skirt similar to door skirt 1073 may also be disposed below the access opening of frame 1002 when barrier 2001 is in place so as to block air from entering or exiting the chamber formed by the barrier through gap 1071 located below frame 1002.
Top portion 2006 of barrier 2001 may extend from the top frame portion 1069 (shown in
Sidewall portion 2002 may further comprise one or more access ports 2004. While shown as running vertically along a middle section of sidewall portion 2002, it is to be understood that access port 2004 may be located anywhere along sidewall portion 2002, and may also be configured non-vertically (e.g., diagonally or horizontally). Access port 2004 may include one or more doors, hanging panels, sliding panels, hinged panels, flaps, curtains, hanging slats, split membrane, air curtains, or any other suitable device or method of inhibiting, resisting, and/or preventing environmental contamination between separate spaces. In one aspect, the environmental access barrier substantially seals access port 2004 before and/or after entry of a technician or other personnel within barrier 2001. The access port 2004 may be closed via, for example, one or more zippers or other suitable closure mechanisms.
Additionally, and/or alternatively, to accessing the interior of frame 1002 via access port 2004, access may be gained by temporarily detaching (and then reattaching) barrier store mechanism 2005 from frame 1002, or by temporarily detaching (and then reattaching) sidewall portion 2002 from barrier store mechanism 2005. Similarly, access may be gained by temporarily detaching (and then reattaching) sidewall portion 2002 from door 1065.
By providing barrier 2001 having an access port 2004, a technician or other personnel may open door 1065 and enter the conditioned environment of the data storage library to access user interfaces of the library, bulk load data storage cartridges, service the library (e.g., replace defective components, add optional components, etc.), or for any other reason while substantially inhibiting an influx of external air into (or escape of conditioned air out of) the data storage library. In this way for example, warm, humid air from outside the data storage library may be inhibited or prevented from entering the interior portions of the data storage library, thereby inhibiting, impeding or preventing the formation of condensation on components therein.

While not shown, side panels 3002 may include an access port or, alternatively and/or additionally, access may be gained into frame 1002 by disconnecting (and then reconnecting) one or more side panels from the barrier store 3005 and/or the door 1065, and/or disconnecting (and then reconnecting) the barrier store from the frame 1002. It is to be understood that barrier storage mechanism 3005 may be located elsewhere (e.g., at door 1065) or there may not be a barrier store mechanism 3005.

While not shown, side panels 4002 may include an access port for access through barrier 4001 or, alternatively and/or additionally, access may be gained into frame 1002 by disconnecting (and then reconnecting) one or more side panels from the barrier store mechanism 4005 and/or the door 1065, and/or disconnecting (and then reconnecting) the barrier store mechanism 4005 from the frame 1002. It is to be understood that barrier store mechanism 4005 may be located elsewhere (e.g., at door 1065) or there may not be a barrier store mechanism 4005.
Next, referring to
As shown in
When door 1065 is closed, side panels 5002 and/or skirt panels 5008 may be housed in a folded, stacked formation within a barrier storage mechanism 5005. On the other hand, when door 1065 is opened, the hanging panels may extend so as to form an environmentally-protected work space around the access opening of frame 1002. Barrier 5001 does not necessarily need to be fully sealed, as hanging panels 5002 may be sufficient to impede exterior environmental conditions from intruding into the chamber formed by the hanging panels and/or substantially maintain the environment within the data storage library while door 1065 is opened, even if small amounts of external air are allowed to enter the chamber formed by the hanging panels and/or the data storage library, and/or small amounts of internal air are allowed to escape. In one aspect, the environmental conditioning unit may be configured to overcome any such minimal losses due to this minor leakage.
While not shown, access may be gained into frame 1002 by simply separating adjacent hanging side panels 5002. The hanging side panels 5002 should naturally return to a “closed” position after entry (or exit) of a technician within the work space.
Additionally, it is to be understood that any features of the embodiments shown and described with respect to
Furthermore, certain features of the barrier may be omitted without unduly effecting the performance of the overall system. For example, in some embodiments, skirts 2008, 3008, 4008, and/or 5008 may be omitted. Also, in some embodiments, top panels 2006, 3006, 4006, and/or 5006 may be omitted. Door skirt 1073 may also be omitted. In such embodiments, the environmental conditioning unit(s) may provide sufficient temperature regulation and/or positive air pressure so as to overcome any losses due to the omitted barrier features. Likewise, door 1065 may not need to be opened for an extended period of time, thereby reducing any losses realized due to the omitted barrier features.
While the embodiments described above with respect to
Next, processes for accessing a data storage library in a manner that inhibits, restricts and/or prevents environmental conditions exterior of the library from intruding into the interior of the library are disclosed, which may be useful, for example, when providing service within the data storage library. In one embodiment, a barrier is provided and erected to surround at least one access opening of a data storage library and provide an environmental blockade to inhibit, restrict, impede, and/or prevent environmental conditions exterior of the library from intruding into the interior of the library. The barrier preferably forms a work space which increases the volumetric capacity of conditioned space available for the technician to provide service within the data storage library.
Referring to
At 6006, at least one barrier is provided, with the at least one barrier coupled between the at least one door and the data storage library so as to form a work space that is substantially insulated and/or isolated from the outside environment. In one aspect the barrier resists, impedes, inhibits and/or prevents exterior environmental conditions, e.g. exterior air, from intruding into the workspace. The barrier preferably extends between the access door and the door frame of the data storage library. As detailed above, the at least one barrier may be coupled to the door such that opening of the door automatically deploys the at least one barrier, thereby increasing the volumetric work space available for a technician to perform a service procedure. However, at 6008, the at least one door is maintained in a closed position during normal library operation, thereby maintaining the at least one barrier in an undeployed and/or retracted position, as well.
At 6010, a determination is made whether or not a service procedure is needed within the data storage library. The determination may be made by a technician based on, for example, routine scheduled maintenance, repair, bulk load/unload of data storage cartridges, etc. or it may be made automatically by a library controller. If no, the at least one door is maintained in a closed position. However, if yes, the at least one door is opened, thereby automatically deploying the at least one barrier between the door and the data storage library, preferably the door frame opening at 6012. Alternatively, the barrier may be deployed manually. With the barrier deployed, the interior space formed by the at least one barrier may be accessed at 6014. For example, the interior of the barrier may be accessed by entering an opening formed on a side of the at least one barrier at 6016. The opening may have a door, flap, slats, split membrane, air curtain, zipper and/or other barrier or closure mechanism to close the opening. In one embodiment, the opening may be substantially sealable. Alternatively, and/or additionally, the interior of the barrier may be accessed by separating one or more coupling points of the at least one barrier to another location on the barrier, the data storage library and/or to the at least one door at 6018. The interior of the data storage library is accessed via the access opening of the at least one data storage library at 6020, thereby enabling a service and/or maintenance procedure to be performed within the data storage library while minimizing and/or preventing the intrusion of unconditioned air from the external environment (e.g., the data center) into the data storage library.
Referring now to
At 7008, a determination is made whether or not a service procedure is needed within the data storage library. The determination may be made by a technician based on, for example, routine scheduled maintenance, repair, bulk load/unload of data storage cartridges, etc. or it may be made automatically by a library controller. If no, the at least one door is maintained in a closed position. However, if yes, the at least one door is opened at 7010. Then, at 7012, with the at least one door opened, at least one barrier is erected between the at least one door and the data storage library, preferably the frame of the data storage library opening, so as to form a work space that is substantially insulated and/or isolated from the outside environment. In one aspect, the barrier resists, impedes, inhibits, and/or prevents exterior environmental conditions, e.g., external air, from intruding into the workspace. The barrier preferably extends between the access door (the access door forming a portion of the barrier) and the door frame of the data storage library. As detailed above, the at least one barrier may be coupled between surfaces of the door and the data storage library so as to increase the volumetric work space available for a technician to perform a service procedure. With the barrier erected, the interior space formed by the at least one barrier may be accessed at 7014. For example, the interior of the barrier may be accessed by entering an opening formed on a side of the at least one barrier at 7016. The opening may have a door, flap, slats, and/or other barrier, or zipper and/or closure mechanism to close the opening. In one embodiment the opening may be substantially sealable. Alternatively and/or additionally, the interior of the barrier may be accessed by separating one or more coupling points of the at least one barrier to another location on the barrier, the data storage library and/or to the at least one door at 7018. Finally, the interior of the data storage library is accessed via the access opening of the at least one data storage library at 7020, thereby enabling bulk load/unload of data storage cartridges, a service and/or maintenance procedure, etc., to be performed within the data storage library while minimizing and/or preventing the intrusion of unconditioned air from the external environment (e.g., the data center) into the data storage library.
It follows that various embodiments described and/or suggested herein are able to provide data storage systems, and optionally, automated data storage libraries having environmental control capabilities associated with the automated data storage library, with at least one barrier system capable of providing an environmentally-controlled access point. As a result, favorable conditions (e.g., temperature, humidity, absence of contaminants, etc.) may be provided and/or substantially maintained for the data storage drives, data storage cartridges, and/or data storage media which may be stored in the library frame, even during service procedures in which the access door(s) or panel(s) of the library frame must be opened. Condensation formation and/or accumulation on the media (and its subsequent effect on contacting devices) may also be resisted, impeded, inhibited, and preferably avoided. Inhibiting and substantially avoiding the formation and accumulation of condensation and moisture may be particularly beneficial for tape libraries, tape cartridges and tape media.
The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.
Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.
These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
Moreover, a system according to various embodiments may include a processor and logic integrated with and/or executable by the processor, the logic being configured to perform one or more of the process steps recited herein. By integrated with, what is meant is that the processor has logic embedded therewith as hardware logic, such as an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc. By executable by the processor, what is meant is that the logic is hardware logic; software logic such as firmware, part of an operating system, part of an application program; etc., or some combination of hardware and software logic that is accessible by the processor and configured to cause the processor to perform some functionality upon execution by the processor. Software logic may be stored on local and/or remote memory of any memory type, as known in the art. Any processor known in the art may be used, such as a software processor module and/or a hardware processor such as an ASIC, a FPGA, a central processing unit (CPU), an integrated circuit (IC), a graphics processing unit (GPU), etc.
