Embodiments of the disclosure generally relate to storage systems and, more specifically, but not by way of limitation, to archiving storage systems.
An archiving storage system is used by one or more applications or application servers to store data for longer periods of time, for example, one year. Governments and other organizations often require the storage of certain types of data for long periods. For example, the Securities and Exchange Commission (SEC) may require retention of financial records for three or more years. Thus, entities that have to meet these storage requirements employ archiving systems to store the data to a media allowing for long-term storage.
Generally, larger organizations with two or more locations may have more than one archiving system. For example, a company may have an office in San Francisco with an archiving system and an office in New York with an archiving system. Each archiving system can store data locally. This configuration however does not permit a consistent storage archive across the organization as each archiving system manages only local data. Thus, these organizations often do not have control over the data that is stored across the organization.
It is in view of these and other considerations not mentioned herein that the embodiments of the present disclosure were envisioned.
The embodiments of the present disclosure are described in conjunction with the appended figures:
In the appended figures, similar components and/or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If only the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label.
The ensuing description provides exemplary embodiment(s) only and is not intended to limit the scope, applicability or configuration of the possible embodiments. Rather, the ensuing description of the exemplary embodiment(s) will provide those skilled in the art with an enabling description for implementing an exemplary embodiment. It being understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the possible embodiments as set forth in the appended claims.
Embodiments of the present disclosure provide a unique and novel archiving system. Embodiments include an archiving system having two or more network storage systems. The network storage systems, in embodiments, include removable hard disk drives embedded in removable disk cartridges, referred to simply as removable disk drives. The removable disk drives allow for expandability and replacement such that the archiving system need not be duplicated to add new or more storage capacity. Further, the removable disk drives provide advantages in speed and data access because, in embodiments, the data is stored and retrieved by random access rather than sequential access. In embodiments, the archiving system accesses, writes, reads, or performs functions on data in one network storage system from another remote network storage system.
Specific details are given in the following description to provide a thorough understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details. For example, circuits may be shown in block diagrams in order not to obscure the embodiments in unnecessary detail. In other instances, well-known circuits, processes, algorithms, structures, and techniques may be shown without unnecessary detail in order to avoid obscuring the embodiments. A computing system may be used to execute any of the tasks or operations described herein. In embodiments, a computing system includes memory and a processor and is operable to execute computer-executable instructions stored on a computer readable medium that define processes or operations described herein.
Also, it is noted that the embodiments may be described as a process which is depicted as a flowchart, a flow diagram, a data flow diagram, a structure diagram, or a block diagram. Although a flowchart may describe the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be re-arranged. A process is terminated when its operations are completed but could have additional steps not included in the figure. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc. When a process corresponds to a function, its termination corresponds to a return of the function to the calling function or the main function.
Moreover, as disclosed herein, the term “storage medium” may represent one or more devices for storing data, including read only memory (ROM), random access memory (RAM), magnetic RAM, core memory, magnetic disk storage mediums, optical storage mediums, flash memory devices and/or other machine-readable mediums for storing information. The term “machine-readable medium” includes, but is not limited to portable or fixed storage devices, optical storage devices, wireless channels and various other mediums capable of storing, containing or carrying instruction(s) and/or data.
Furthermore, embodiments may be implemented by hardware, software, firmware, middleware, microcode, hardware description languages, or any combination thereof. When implemented in software, firmware, middleware or microcode, the program code or code segments to perform the necessary tasks may be stored in a machine-readable medium such as a storage medium. A processor(s) may perform the necessary tasks. A code segment may represent a procedure, a function, a subprogram, a program, a routine, a subroutine, a module, an object, a software package, a class, or any combination of instructions, data structures, or program statements. A code segment may be coupled to another code segment or a hardware circuit by passing and/or receiving information, data, arguments, parameters, or memory contents. Information, arguments, parameters, data, etc., may be passed, forwarded, or transmitted via any suitable means including memory sharing, message passing, token passing, network transmission, etc.
An embodiment of a removable disk system 100 to provide long-term archival data storage is shown in
The embedded memory 104, in embodiments, is not physically destroyed with ease and is reusable if the data in the memory is removed, erased, altered, or changed. For example, the removable disk drive 102-1 is a hard drive that includes a magnetic media. To destroy the data, the magnetic media may need to be removed and destroyed in an industrial shredder or other device that physically destroys the media. However, in embodiments, the data on the hard drive could be altered and the hard drive reused without allowing the data to be retrieved.
In embodiments, the removable disk system 100 contains a drive port 110-1 that includes one or more data cartridge ports 112, each with a data cartridge connector 114 to receive the removable disk drive 102-1. The data cartridge connector 114 mates with the electrical connector 106 of the removable disk drive 102-1 to provide an electrical connection to the removable disk drive 102-1 and/or to communicate with the embedded memory 104 in the removable disk drive 102-1. As with the electrical connector 106, the data cartridge connector 114 may be a SATA connector or another type of connector. Regardless, the data cartridge connector 114 and the electrical connector 106 can be physically and/or electrically connected. The data cartridge port 112 allows the data cartridge case 108 of the removable disk drive 102-1 to be easily inserted and removed as necessary. In embodiments, the drive port 110-1 includes two or more data cartridge ports 112 to allow for the use, control and communication with two or more removable disk drives 102-1. Each drive port 110-1, in embodiments, is separately addressable to allow for customized control over each removable disk drive 102-1 connected to each data cartridge port 112. Thus, as removable disk drives 102-1 are replaced, the same controls can be applied to the newly inserted removable disk drives 102-1 because the drive port 110-1 is addressed instead of the removable disk drives 102-1.
The embedded memory 104 may be read and used by the firmware 116 of the drive port 110-1. The firmware 116 may be hardware and/or software resident in the drive port 110-1 for controlling the removable disk drive 102-1. In embodiments, the firmware 116 contains the necessary software and/or hardware to power-up the removable disk drive 102-1, spin-up the disk platters in the embedded memory 104, read and write to the embedded memory 104, read, write and process metadata, etc. For example, the firmware 116 could read the embedded memory 104 to identify the removable disk drive 102-1 and gather information related to the contents of the data.
In embodiments, the removable disk system 100 operates to receive one or more removable disk drives 102-1 in the one or more drive ports 110-1. The electrical connector 106 physically connects or couples with the data cartridge connector 114 to form an electrical connection that allows the drive port 110-1 to communicate with the embedded memory 104. The firmware 116 powers-up the embedded memory 104 and begins any initialization processes (e.g., security processes, identification processes, reading and/or writing, etc.). The drive port 110-1, which, in embodiments, is in communication with a network, receives archival data from one or more servers, applications, or other devices or systems on the network. The firmware 116 writes the archival data to the embedded memory 104 of the removable disk drive 102-1 to archive the data.
An embodiment of the hardware architecture of an archiving system 200 is shown in
The network storage system 202 comprises one or more components that may be encompassed in a single physical structure or be comprised of discrete components. In embodiments, the network storage system 202 includes an archiving system appliance 210 and one or more removable disk drives 102-2 connected or in communication with a drive port 110-2. In alternative embodiments, a modular drive bay 212 and/or 214 includes two or more drive ports 110-2 that can each connect with a removable disk drive 102-2. Thus, the modular drive bays 212 and 214 provide added storage capacity because more than one removable disk drive 102-2 can be inserted and accessed using the same archiving system appliance 210. Further, each drive port 110-2 in the modular drive bays 212 and 214 are, in embodiments, separately addressable allowing the archiving system appliance 210 to configure the removable disk drives 102-2 in the modular drive bays 212 and 214 into groups of one or more removable disk drives 102-2. Two or more modular drive bays 212 and 214, in embodiments, are included in the network storage system 202, as evidenced by the ellipses 218. Thus, as more data storage capacity is required, more modular drive bays 212 and 214 may be added to the network storage system 202.
The exemplary hardware architecture in
The archiving system appliance 210, in embodiments, is a server operating as a file system. The archiving system appliance 210 may be any type of computing system having a processor and memory and operable to complete the functions described herein. An example of a server that may be used in the embodiments described herein is the PowerEdge™ 2950 Server offered by Dell Incorporated of Austin, Tex. The file system executing on the server may be any type of file system, such as the NT File System (NTFS), that can complete the functions described herein.
In embodiments, the two or more modular drive bays 212 and/or 214, having each one or more inserted removable disk drives 102-2, form a removable disk array (RDA) 232-1. The archiving system appliance 210 can configure the RDA 232-1 into one or more independent file systems. Each application server 206 or 208 requiring archiving of data may be provided a view of the RDA 232-1 as one or more independent file systems. In embodiments, the archiving system appliance 210 logically partitions the RDA 232-1 and logically associates one or more drive ports 110-2 with each application layer partition. Thus, the one or more removable disk drives 102-2 comprising the application layer partition appears as an independent file system.
In further embodiments, the archiving system appliance 210 provides an interface for application server 1206 and application server 2208 that allows the application servers 206 and 208 to communicate archival data to the archiving system appliance 210. The archiving system appliance 210, in embodiments, determines where and how to store the data to one or more removable disk drives 102-2. For example, the application server 1206 stores archival data in a first application layer drive, such as, the first three removable disk drives. The application layer drives are, in embodiments, presented to the application servers 206 and 208 as application layer drives where write and read permissions for any one application layer drive is specific to one of the application servers. As such, the network storage system 202 provides a multiple and independent file system to each application server 206 and 208 using the same hardware architecture. In embodiments, the archival data is also referred to as an information element and may include, but is not limited to, a file, a memory sector, a data structure, a table, or other type or format of data.
In alternative embodiments, the network storage system 202 also comprises a fixed storage 216. The fixed storage 216 may be any type of memory or storage media either internal to the archiving system appliance 210 or configured as a discrete system. For example, the fixed storage 216 is a Redundant Array of Independent Disks (RAID), such as the Xtore XJ-SA12-316R-B from AIC of Taiwan. The fixed storage 216 provides an active archive for storing certain data for a short period of time where the data may be more easily accessed. In embodiments, the archiving system appliance 210 copies archival data to both the fixed storage 216 and the removable disk drive 102-2. If the data is needed in the short term, the archiving system appliance 210 retrieves the data from the fixed storage 216.
The archiving system appliance 210 can also configure the active archive in the fixed storage 216 into one or more independent file systems, as with the RDA 232-1. As explained above, each application server may be provided a view of one of two or more independent file systems. Each independent file system may comprise an application layer partition in the RDA 232-1 and a related application layer partition in the fixed storage 216. In embodiments, the archiving system appliance 210 partitions the fixed storage 216 and associates each application layer partition in the fixed storage 216 with an associated application layer partition in the RDA 232-1.
As explained above, the archiving system appliance 210, in embodiments, determines where and how to store the data to one or more removable disk drives 102-2. For example, the application server 1206 stores archival data in a first application layer drive, which may include storing the archival data in the application layer partition in the fixed storage 216 for easier access to the archival data. Again, the application layer drives are, in embodiments, presented to the application servers 206 and 208 where write and read permissions for any one application layer drive is specific to one of the application servers. As such, the network storage system 202 provides a multiple and independent file system to each application server 206 and 208 using the same hardware architecture.
In operation, application server 1206 stores primary data into a primary storage 228, which may be a local disk drive or other memory. After some predetermined event, the application server 1206 reads the primary data from the primary storage 228, packages the data in a format for transport over the network 204 and sends the archival data to the network storage system 202 to be archived. The archiving system appliance 210 receives the archival data and determines where the archival data should be stored. The archival data, in embodiments, is then sent to the related application layer partitions in both the fixed storage 216 and the RDA 232-1, which may comprise one or more of the removable disk drives 102-2 in one or more of the drive ports 110-2. The archival data is written to the removable disk drive 102-2 for long-term storage and is written to the fixed storage 216 for short-term, easy-access storage. In further embodiments, application server 2208 writes primary data to a primary storage 230 and also sends archival data to the network storage system 202. In some embodiments, the archival data from application server 2208 is stored to a different removable disk drive 102-2 and a different portion of the fixed storage 216 because the archival data from application server 2208 relates to a different application and, thus, a different application layer partition.
A block diagram of an archiving system 300 is shown in
The network storage system 302, in embodiments, comprises one or more functional components embodied in hardware and/or software. In one embodiment, the network storage system 302 comprises an archiving system 312-1 in communication with one or more drive ports 110-3 that are in communication with one or more removable disk drives 102-3. The drive ports 110-3 and removable disk drives 102-3 are similar in function to those described in conjunction with
In further embodiments, the network storage system 302 comprises an archival management system 310-1. The archival management system 310-1 receives data for archiving from one or more systems on the network 304. Further, the archival management system 310-1 determines to which system or removable disk drive 102-3 the data should be archived, in which format the data should be saved, and how to provide security for the network storage system 302. In embodiments, the archival management system 310-1 provides a partitioned archive such that the network storage system 302 appears to be an independent file system to each separate application server 306, yet maintains the archive for multiple application servers 306. Thus, the archival management system 310-1 manages the network storage system 302 as multiple, independent file systems for one or more application servers 306. In embodiments, the archival management system 310-1 and the archiving system 312-1 are functional components of the archiving system appliance 210 (
In embodiments, the archival management system 310-1 saves archival data to both the archiving system 312-1 and an active archive 314. The active archive 314, in embodiments, controls, reads from and writes to one or more fixed storage devices 316 that allow easier access to archived data. In embodiments, fixed storage 316 is similar in function to fixed storage 216 (
The archival management system 310-1 may also provide an intelligent storage capability. Each type of data sent to the network storage system 302 may have different requirements and controls. For example, certain organizations, such as the SEC, Food and Drug Administration (FDA), European Union, etc., have different requirements for how certain data is archived. The SEC may require financial information to be kept for seven (7) years while the FDA may require clinical trial data to be kept for thirty (30) years. Data storage requirements may include immutability (the requirement that data not be overwritten), encryption, a predetermined data format, retention period (how long the data will remain archived), etc. The archival management system 310-1 can apply controls to different portions of the RDA 232-2 and the active archive 314 according to user-established data storage requirements. In one embodiment, the archival management system 310-1 creates application layer partitions in the archive that span one or more removable disk drives 102-3 and one or more portions of the fixed storage 316. All data to be stored in any one application layer partition can have the same requirements and controls. Thus, requirements for data storage are applied to different drive ports 110-2 (
The network storage system 302 may also comprise a database 318-1 in communication with the archival management system 310-1. The database 318-1 is, in embodiments, a memory for storing information related to the data being archived. The database 318-1 may include HDDs, ROM, RAM or other memory either internal to the network storage system 302 and/or the archival management system 310-1 or separate as a discrete component addressable by the archival management system 310-1. The information stored in the database 318-1, in embodiments, includes one or more of, but is not limited to, data identification, application server identification, time of storage, removable disk drive identification, data format, encryption keys, application layer partition organization, etc.
The network 304, in embodiments, connects, couples, or otherwise allows communications between one or more other systems and the network storage system 302. For example, the application server 306 is connected to the network storage system 302 via the network 304. The application server 306 may be a software application, for example, an email software program, a hardware device, or other network component or system. The application server 306, in embodiments, communicates with a memory that functions as the application server's primary storage 308. The primary storage 308 is, in embodiments, a HDD, RAM, ROM, or other memory either local to the application server 306 or in a separate location that is addressable.
In embodiments, the application server 306 stores information to the primary storage 308. After some predetermined event, such as the expiration of some period of time, the application server 306 sends data to the network storage system 302 to archive the data. The application server 306 may send the data by any network protocol, such as TCP/IP, HTTP, etc., over the network 304 to the network storage system 302. The data is received at the archival management system 310-1. The archival management system 310-1, in embodiments, sends the data to one or both of the active archive 314 and/or the archiving system 312-1 to be archived.
An embodiment of a networked archiving system 400 is shown in
In embodiments, one of the two or more network storage systems 402, 404, 406, and 408 is a primary network storage system. For example, network storage system #1402 is the primary network storage system. The primary network storage system 402 can control, direct, change, or request operations of the other network storage systems 404, 406, and 408 in the archiving system 400. In one embodiment, the primary network storage system 402 maintains a database 416 containing information, archived data, metadata, or other data from one or more of the other network storage systems 404, 406, and 408. An administrator or other user may access the aggregated data in the database 416 through the primary network storage system 402 or, in alternative embodiments, by a request to the primary network storage system 402 from one of the other network storage systems 404, 406, and 408. The primary network storage system 402 may send requests for data or information to any other network storage system 404, 406, and 408 and receive response from the network storage systems 404, 406, and 408. In further embodiments, the network storage systems 404, 406, and 408 may also send requests to and receive response from the primary network storage system 402 or any other of the network storage system.
The aggregated archive data can allow the primary network storage system 402 to identify all the archival data in the archiving system 400. To aggregate data, the primary network storage system 402 sends a request for new or updated data to one or more of the other network storage systems 404, 406, and 408. For example, the primary network storage system 402 sends a request for data to the network storage system #4408. The network storage system #4408, in embodiments, accesses the local archive 412, which may be the RDA 232-2 (
Embodiments of an archival management system 310-2 and an archiving system 312-2, including one or more components or modules, are shown in
The active archive management module 504, in embodiments, manages data written to and read from the active archive 314 (
The audit module 505, in embodiments, stores data about the archival data stored in the archiving system 312-2 and active archive 314 (
In embodiments, the remote archive interface module 515 sends or receives data, inputs and/or actions, over the network 514, to another network storage system in the archiving system. For example, a system may request data stored at a distantly located network storage system. The request can be sent to the remote network storage system using the remote archive interface 515. Likewise, the remote archive interface module 515 may receive or send data, inputs, and/or actions sent from or sent to remote network storage systems over the network 514.
The archiving system 312-2, in embodiments, includes one or more of an authenticity module 506, an indexing module 508, and/or a placement/media management module 510. In embodiments, the authenticity module 506 determines if a removable disk drive is safe to connect with the archiving system 312-2. For example, the authenticity module 506 may complete an authentication process, such as, AES 256, a public-key encryption process, or other authentication process, using one or more keys to verify that the inserted removable disk drive has access to the archiving system 312-2. In embodiments, the authenticity module 506 saves any authentication information for a removable disk drive to the local database 318-2 when the removable disk drive is first created. This authentication information, in embodiments, remains locally stored to protect the information. In embodiments, the authenticity module 506, upon a request for the authentication information received at the remote archive interface 515, reads the authentication information from the database 318-2 and sends the authentication information to the remote archive interface 515 for transport of a network 514.
The indexing module 508, in embodiments, creates application layer partitions in the RDA 232-3 to provide storage areas for different data. For example, the indexing module 508 selects one or more removable disk drives to form one or more “drives”. “Drive A:\” may comprise one or more removable disk drives, while “Drive B:\” and “Drive C:\” may also include one or more removable disk drives. In embodiments, each drive is associated with an application layer partition of the RDA 232-3. There may be fewer than three application layer partitions of the RDA 232-3 or more than three application layer partitions of the RDA 232-3. In embodiments, each drive or application layer partition stores only a predetermined type of data that relates to one or more application servers. For example, Drive A:\ stores email data, while Drive B:\ stores Health Insurance Portability and Accountability Act (HIPAA) data.
In further embodiments, the active archive management module 504 creates application layer partitions in the active archive 314 (
The application server(s) 206 and 208 (
In further embodiments, the active archive management module 504 provides controls for each drive in the active archive 314 (
In embodiments, the placement/media management module 510 manages the removable disk drives in the RDA 232-3. For example, the placement/media management module 510 determines when cartridges need replacing because the removable disk drive is at or near capacity. In embodiments, the placement/media management module 510 also separately addresses the removable disk drives and provides the addressing information to the indexing module 508 for storing data in the correct application layer partition.
An embodiment of an archive 600 having one or more data structures for one or more files is shown in
In embodiments, a file data structure 602 may comprise a file identifier 614, file metadata 616, and file data 618. A file identifier 614 may be any identifier of the file, for example a file GUID.

In another embodiment, the archive file system identifier 714 is an identifier for the network storage system in the archiving system that created the removable disk drive. A removable disk drive, when first inserted, is formatted with information, such as authentication information. This information is stored locally at the network storage system that created the removable disk drive. To retrieve the authentication information, the network storage system that created the removable disk drive, in embodiments, needs to be known. As such, an identifier for each network storage system can be stored in the data element field 702. Thus, if the data about the file or information element is aggregated, the network storage system that created the removable disk drive will be known. In one embodiment, the archive file system identifier 714 is a GUID for the network storage system. In another embodiment, the archive file system identifier 714 is a name assigned to the network storage system. For example, network storage system #1402 (

An embodiment of a method 1300 for providing remotely-stored but locally-read data is shown in
In embodiments, data may be stored on a removable disk drive. At some point, the removable disk drive may be removed and placed in storage in a separate physical location. The removable disk drive may then be retrieved from the storage location and reinserted into a drive port of a network storage system. However, the network storage system having the reinserted removable disk drive may not be the same network storage system that stored the data. As such, the network storage system will not be able to authenticate the removable disk drive because the authentication information may be stored with a remote network storage system.
Receive operation 1304 receives a request to read data from a removable disk drive. In embodiments, a request for data is received at a network storage system, which may be the primary network storage system 402 (
Determine operation 1306 determines if the removable disk drive was created locally. In embodiments, the authenticity module 506 (
Determine operation 1308 determines the remote storage system that created the removable disk drive. In embodiments, the archival management system 310 (
Send operation 1310 sends a request for the authenticity information to the remote network storage system. Every removable disk drive, in embodiments, has a set of authenticity information, such as public key encryption keys or other information, used to authenticate the disk drive. This authentication information is stored locally at the network storage system. In embodiments, the primary network storage system 402 (
Receive operation 1312 receives the authentication information. In embodiments, the other network storage system 404, 406, and 408 (
Authenticate operation 1314 authenticates the removable disk drive. In embodiments, the network storage system authenticates the inserted removable disk drive with the received authentication information. The authentication process may be any authentication method known in the art, such as symmetric or asymmetric encryption methods, public key or private key encryption, or other authentication or encryption method. Likewise, the authentication information is any information used to complete the authentication.
Read operation 1316 reads the requested data. After authenticating the removable disk drive, the network storage system can access the removable disk drive and read the data. Provide operation 1318 provides the read data for the requester.
In light of the above description, a number of advantages of the present disclosure are readily apparent. For example, the archiving system is further expandable by providing two or more network storage systems. However, the archiving system can still communicate data among the network storage systems to fulfill action requests. Further, the archiving system may be controlled centrally by a primary network storage system; thus, the archiving system achieves greater stability over the many network storage systems.
A number of variations and modifications of the disclosure can also be used. For example, a shared control over the archiving system that includes two or more network storage systems may be located instead of a single primary network storage system. Further, the aggregated database may be duplicated to all network storage systems to allow quick fail-over of the primary network storage system if a network storage system malfunctions.
While the principles of the disclosure have been described above in connection with specific apparatuses and methods, it is to be clearly understood that this description is made only by way of example and not as limitation on the scope of the disclosure.
