Description

TECHNICAL FIELD

This disclosure relates to storage device carriers and, more particularly, to storage device carriers that provide enhanced cooling.

BACKGROUND

In today's IT infrastructure, high availability is of paramount importance. Specifically, critical (and sometimes non-critical) components within an IT infrastructure are often layered in redundancy. For example, primary servers may be supported by backup servers; primary switches may be supported by backup switches; primary power supplies may be supported by backup power supplies; and primary storage systems may be supported by backup storage systems.

Oftentimes, the various IT components mounted within IT racks consume considerable power and, therefore, produce considerable heat. Accordingly, these various IT components need to be provided with ample cooling in order to avoid heat-related failures.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, IT racks (e.g., IT rack 10) may be utilized to store and organize IT components. For example, IT rack 10 may be placed within a computer room and various IT components (e.g., IT component 12) may be attached to rails (e.g., NEMA rails 14, 16) included within IT rack 10, wherein these rails (e.g., NEMA rails 14, 16) may have a standard and defined spacing between them (e.g., 19″). Typically, IT components that are configured to fit within IT rack 10 may be described as rack-mountable IT components.

Examples of the various IT components (e.g., IT component 12) mountable within IT rack 10 may include but are not limited to: server systems, disk array systems, storage processor systems, storage processor/disk systems, and battery backup systems.

IT rack 10 may include frame 18 (which may include one or more vertical supports, horizontal supports, and cross braces) to which NEMA rails 14, 16 may be attached. NEMA rails 14, 16 may include a plurality of evenly spaced holes that may be configured for mounting the various IT components within IT rack 10. By standardizing the spacing between NEMA rails 14, 16, the various IT components that fit within a first IT rack may also fit within a second IT rack.

Typically, IT racks are defined in accordance with the number of rack units (U's) included within the rack. For example, a 1U IT component is half as high as a 2U IT component, which is half as high as a 4U IT component. Accordingly, while the number of rack units available within a particular IT rack may be rigidly defined by the size of the IT rack, the number of IT components mountable within that IT rack may vary depending upon the size (in rack units) of the particular IT components being mounted within that IT rack. Therefore, by reducing the number of rack units that a particular IT component uses within an IT rack, additional IT computing devices may be mounted within the IT rack.

Referring to FIG. 2, there is shown one example of IT component 12, namely rack-mountable computing device 50. In this particular embodiment, rack-mountable computing device 50 may include a plurality of individual components, examples of which may include but are not limited to storage components, input/output components, and processing components, any of which may be a field replaceable unit (FRU) that is serviceable in the field.

Storage components may be the portion of rack-mountable computing device 50 that is configured to store data. Examples of such data may include but are not limited to data that is generated remotely (e.g., by applications that are executed on remote devices) or data that is generated locally (e.g., by applications that are executed on rack-mountable computing device 50). Accordingly, the storage component may be configured to include one or more storage devices, examples of which may include but are not limited to one or more electro-mechanical (e.g., rotating-media) storage devices (e.g., SATA drives or SCSI drives) and/or one or more solid state storage devices (e.g., flash drives). For example and as shown in FIG. 2A, the storage component of rack-mountable computing device 50 may be configured to include (in this example) twelve 2.5 inch form factor storage devices (e.g., storage devices 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74) that are accessible through the front panel of rack-mountable computing device 50.

Input/output components of rack-mountable computing device 50 may be the portion of rack-mountable computing device 50 that is configured to couple rack-mountable computing device 50 to a network infrastructure (e.g., network infrastructure 76), wherein network infrastructure 76 may be configured to couple rack-mountable computing device 50 to other rack-mountable computing devices, other IT components (e.g., server systems, disk array systems, storage processor systems, storage processor/disk systems, and battery backup systems), other networking devices (e.g., switches, routers, bridges, wireless access points), and/or end user computing devices (e.g., desktop computers, laptop computers, notebook computers, smartphones, tablet computers, etc.). Examples of network infrastructure 76 may include but are not limited to an Ethernet infrastructure; a fiber channel infrastructure; and an infiniband infrastructure.

Processing components of rack-mountable computing device 50 may be the portion of rack-mountable computing device 50 that is configured to process data, such as data that is generated remotely (e.g., by applications that are executed on remote devices) or data that is generated locally (e.g., by applications that are executed on rack-mountable computing device 50). Accordingly, the processing components of rack-mountable computing device 50 may be configured to include one or more microprocessors.

As the capabilities of rack-mountable computing device 50 continue to increase, the power consumption of rack-mountable computing device 50 may also continue to increase. And, therefore, the heat generated by rack-mountable computing device 50 may also continue to increase. Accordingly, enhanced methods of cooling rack-mountable computing device 50 may be needed to avoid heat-related component failure.

Referring also to FIG. 3, there is shown storage device carrier system 100. Storage device carrier system 100 may be configured to removeably secure a storage device (e.g., storage device 102) within an enclosure assembly. Example of such an enclosure assembly may include but are not limited to a chassis, a sub-chassis, an enclosure, and a sub-enclosure (or portion thereof) of rack-mountable computing device 50. Examples of storage device 102 may include but are not limited to solid state storage devices and/or electro-mechanical storage devices (e.g., one or more of storage devices 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74).

Accordingly and through the use of storage device carrier system 100, rack-mountable computing device 50 may be configured to be easily serviceable in the field by service technicians. Specifically, storage devices (e.g., storage device 102) may be easily removed from and/or installed into rack-mountable computing device 50 without requiring the use of tools.

While the following discussion concerns storage device carrier system 100 being utilized within rack-mountable computing device 50, this is for illustrative purposes only and is not intended to be a limitation of this disclosure, as other configurations are possible and are considered to be within the scope of this disclosure. For example, storage device carrier system 100 may be utilized within commercial-grade, non-rack-mountable computing devices or consumer-grade computing devices.

Referring also to FIGS. 4A-4B, the storage devices within (in this example) rack-mountable computing device 50 may be densely packaged. For example, rack-mountable computing device 50 is shown in this implementation to include seventy-two storage devices (i.e., three rows of twenty-four storage devices). Since some solid state storage devices may dissipate up to 25 watts of thermal energy each, the system shown in FIG. 4A (which includes seventy-two storage devices) may generate up to 1,800 watts of thermal energy that will need to be dissipated in order to avoid thermal failure.

Accordingly, rack-mountable computing device 50 may be configured to provide cooling air that passes across the surfaces of (in this example) these seventy-two storage devices. As discussed above, rack-mountable computing device 50 may be configured to be easily serviceable in the field by service technicians, wherein one or more of these seventy-two storage devices (e.g., storage device 102) may be easily removed from and/or installed into rack-mountable computing device 50 without requiring the use of tools. Further and since rack-mountable computing device 50 may be configured for high availability, one or more of these seventy-two storage devices (e.g., storage device 102) may be easily removed from and/or installed into rack-mountable computing device 50 without requiring rack-mountable computing device 50 to be powered down.

Unfortunately and when the portion (e.g., drawer 150) of rack-mountable computing device 50 that contains (in this example) the seventy-two storage devices is slid out of chassis 152 of rack-mountable computing device 50 (in a fashion similar to a drawer sliding out of a piece of furniture), cooling air intended to be circulated around the storage devices may bleed out upward from the gaps between the storage devices (as represented by air bleed arrows 154) instead of passing through the entirety of rack-mountable computing device 50 and out of exhaust port 156 proximate front surface 158 of rack-mountable computing device 50. This may result in uneven cooling and/or overheating of one or more of (in this example) the seventy-two storage devices.

For example, if one or more cooling fans (not shown) are positioned at the rear of rack-mountable computing device 50 and provide positive air flow toward the front of rack-mountable computing device 50, when drawer 150 is slid out of chassis 152, cooling air may bleed out upward from the gaps between the storage devices (as represented by air bleed arrows 154), resulting in very little (if any) cooling air passing by the row of twenty-four storage devices positioned proximate front surface 158 of rack-mountable computing device 50. And this situation may result in these twenty-four storage devices not being properly cooled and possibly overheating and/or failing.

Referring also to FIG. 5, there is shown a general implementation of a storage device carrier system that is configured to reduce/eliminate the bleeding of cooling air upward from the gaps between the storage devices (as represented by air bleed arrows 154, FIG. 4B). Accordingly, storage device carrier system 200 may include carrier assembly 202 configured to releasably engage a storage device (e.g., storage device 102) and configured to be releasably received within a storage device bay within an IT component (e.g., rack-mountable computing device 50). As discussed above, examples of storage device 102 may include but are not limited to solid state storage devices and/or electro-mechanical storage devices (e.g., one or more of storage devices 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74).

Storage device carrier system 200 may include electrical coupler assembly 204 that may be configured to electrically couple storage device 102 to the IT component (e.g., rack-mountable computing device 50). For example, coupler assembly 204 may include a first electrical connector for releasably coupling storage device 102 to storage device carrier system 200 and a second electrical connector for releasably coupling storage device carrier system 200 to a system board (not shown) included within the IT component (e.g., rack-mountable computing device 50), thus allowing storage device carrier system 200 to be easily removed from (and/or inserted into) the IT component (e.g., rack-mountable computing device 50) in the event that e.g., storage device 102 needs to be replaced.

As will be explained below in greater detail, storage device carrier system 200 may include thermal sealing assembly 206 that may be configured to reduce the leakage of cooling air from around storage device carrier system 200. Storage device carrier system 200 may also include latch assembly 208 that may be configured to releasably lock storage device carrier system 200 within a storage device bay of the IT component (e.g., rack-mountable computing device 50).

Fixed-Position Fin Storage Device Carrier System

Referring also to FIGS. 6A-6C, there is shown one specific implementation of storage device carrier system 200 (namely storage device carrier system 300) in which thermal sealing assembly 302 is configured to seal a fixed width air gap. For example, thermal sealing assembly 302 may be configured to seal at least a portion of the air gap between (in this example) storage device carrier system 300 and an adjacent storage device carrier system (e.g., storage device carrier system 304 and/or storage device carrier system 306) within the IT component (e.g., rack-mountable computing device 50).

Specifically and in this implementation, thermal sealing assembly 302 may include a first fixed-position fin assembly (e.g., fixed-position fin assembly 308) configured to extend a first longitudinal edge (e.g., longitudinal edge 310) of storage device carrier system 300. Additionally, thermal sealing assembly 302 may include a second fixed-position fin assembly (e.g., fixed-position fin assembly 312) configured to extend a second longitudinal edge (e.g., longitudinal edge 314) of the storage device carrier system 300. Accordingly, the combination of fixed-position fin assemblies 308, 312 may effectively close the air gaps through which the bleeding of cooling air occurs (as represented by air bleed arrows 154, FIG. 4B).

Multi-Position Fin Storage Device Carrier System

Referring also to FIG. 7, there is shown one specific implementation of storage device carrier system 200 (namely storage device carrier system 400) in which thermal sealing assembly 402 is configured to seal a variable width air gap. Thermal sealing assembly 402 may include first multi-position fin assembly 404 configured to extend first longitudinal edge 406 of storage device carrier system 400. Additionally, thermal sealing assembly 402 may include second multi-position fin assembly 408 configured to extend second longitudinal edge 410 of storage device carrier system 400.

As will be discussed below, first multi-position fin assembly 404 and second multi-position fin assembly 408 may be configured to be locked in various positions. Accordingly, thermal sealing assembly 402 may include first fin latch assembly 412 configured to releasably lock first multi-position fin assembly 404 in one or more positions. Additionally, thermal sealing assembly 402 may include second fin latch assembly 414 configured to releasably lock second multi-position fin assembly 408 in one or more positions.

Referring also to FIGS. 8A-8B, thermal sealing assembly 402 may be configured to seal at least a portion of the air gap between (in this example) storage device carrier system 400 and an adjacent storage device carrier system (e.g., storage device carrier system 416 and/or storage device carrier system 418) within the IT component (e.g., rack-mountable computing device 50). For example, first multi-position fin assembly 404 may be unlocked (via first fin latch assembly 412) and extended outward to contact second fin assembly 420 of storage device carrier system 416; and second multi-position fin assembly 408 may be unlocked (via second fin latch assembly 414) and extended outward to contact first multi-position fin assembly 422 of storage device carrier system 418. Accordingly, the combination of multi-position fin assemblies 404, 408 may effectively close the air gaps through which the bleeding of cooling air occurs (as represented by air bleed arrows 154, FIG. 4B).

Additionally and referring also to FIGS. 9A-9B, thermal sealing assembly 402 may be configured to seal at least a portion of an adjacent empty storage device bay (e.g., empty storage bay 424) within the IT component (e.g., rack-mountable computing device 50). For example, second multi-position fin assembly 408 may be unlocked (via second fin latch assembly 414) and extended outward to contact first multi-position fin assembly 426 of storage device carrier system 428. Accordingly, the combination of multi-position fin assemblies 408, 426 may effectively close the air gap caused by empty storage bay 424 through which the bleeding of cooling air occurs (as represented by air bleed arrows 154, FIG. 4B).
