2. Description of the Related Art
As the value and use of information continue to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes, thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
An information handling system can be configured in several different configurations. The information handling system can include multiple computers or servers with one or more processors. Each server can be physically mounted in an enclosure. The information handling system can further include storage systems that use storage devices such as hard disk drives. In one configuration, multiple hard disk drives are mounted in the enclosure and are connected to power and data connections in the information handling system. The enclosure can also include cooling devices such as fans that are mounted to cool the components of the server.
In one configuration, a shroud is mounted in the enclosure to direct the flow of cooling air from the cooling devices to the electronic components, such as the processor, memory and various other electronic components, in the server that require cooling. The shroud occupies valuable space within the server chassis and is a non-essential part of the server.

FIGS. 8 and 9 illustrate details of supplemental storage device 500 and supplemental storage device carrier 600. Supplemental storage device 500 has a top side 502, a bottom side 504, a front side 506, a back side 508 and side surfaces 510. Example supplemental storage device 500 is generally rectangular in shape. A connector 520 is attached to back side 508. Connector 520 mates with another connector (not shown) on supplemental storage device printed circuit board 344 (FIG. 6). In one embodiment, supplemental storage devices 500 can be conventional hard disk drives that contain magnetic media arranged on rotating platters that are accessed by a moveable read/write head. In another embodiment, supplemental storage devices 500 can be solid state storage drives that contain non-volatile or flash memory devices.
The supplemental storage device 500 is attached or coupled to supplemental storage device carrier 600. Supplemental storage device carrier 600 partially surrounds supplemental storage device 500. The supplemental storage device carrier 600 has a frame 610. A pair of C-shaped arms 612 extends from opposite sides of frame 610. A spring clip 614 is formed in each of arms 612. Bottom frame 610 and arms 612 define a receptacle 620 that receives the supplemental storage device 500. Supplemental storage device 500 is slid into receptacle 620 such that frame 610 is adjacent to bottom side 504 and C-shaped arms 612 surround side surfaces 510 and extend over top side 502. The spring clips 614 are pressed against top side 502. Fasteners 616 affix supplemental storage device carrier 600 to supplemental storage device 500. Four L-shaped hooks 630 extend perpendicularly away from the bottom surface of frame 610. Two of the L-shaped hooks 630 are positioned on frame 610 towards supplemental storage device front side 506 and two are positioned toward supplemental storage device back side 508.
Turning to FIG. 7, the combination of the supplemental storage device carrier 600 and the attached supplemental storage device 500 are inserted into supplemental storage tray 300. Initially, the bracket 362 of retention mechanism 360 is in an open position as shown by the left most retention mechanism 360 in FIG. 7. Bracket 362 and handle 380 are rotated clockwise away from supplemental storage tray 300.
The supplemental storage device carrier 600 with supplemental storage device 500 included therein is inserted into one of the bays 312 such that frame 610 is adjacent to bottom plate 302 and the L-shaped hooks 630 extend through retention feature openings 316. The supplemental storage device carrier 600 is moved within bay 312 towards front plate 304 such that the L-shaped hooks 630 slide into bottom plate grooves 318. The L-shaped hooks 630 and the bottom plate 302 are dimensioned such that an interference fit is created between the hook portion of L-shaped hooks 630 and bottom plate 302. In this position, the supplemental storage device carrier 600 is mounted to supplemental storage tray 300 by L-shaped hooks 630 and retention feature 316. Also, in this position, the storage device connector 520 is mated and engaged with the storage device connector 354 of printed circuit board 344.
The handle 380 and bracket 362 are rotated counterclockwise about pin 370 until the handle 380 abuts and extends slightly over front wall 304. In this position, the spring loaded latch 392 of lock 390 is engaged with the tab 394 on the inner side of front plate 304 such that the retention mechanism 360 is in a closed position and is also in a locked state, as shown by the right most retention mechanism 360. The retention mechanism 360 holds the supplemental storage device carrier 600 and storage device 500 to supplemental storage tray 300.
The supplemental storage device carrier 600 and storage device 500 can also be selectively removed from the supplemental storage tray 300. A user can depress the spring loaded latch 392 of lock 390 causing the disengagement of tab 394 from latch 392. The bracket 362 and handle 380 are rotated clockwise away from supplemental storage tray 300 to an open position, as shown by the left most retention mechanism 360 in FIG. 7. The supplemental storage device carrier 600 is moved within bay 312 away from front plate 304 such that the L-shaped hooks 630 disengage from bottom plate grooves 318. The supplemental storage device carrier 600 and storage device 500 can then be removed from supplemental storage tray 300.
With reference to FIGS. 2, 3 and 6, the supplemental storage tray 300 containing supplemental storage devices 500 is mounted into a non-essential area 710 within the interior cavity 212. The supplemental storage tray 300 is positioned about a central area of chassis 200. In particular, the supplemental storage tray 300 is suspended from side walls 208 and is located above processors 105 and memory devices 110. Specifically, the supplemental storage tray rails 336 extend over and rest on the chassis wall shoulders 220. The bottom most portion of the rails 336 are tapered and are received in shoulder slots 224. The tab 222 of the center shoulder 220 extends upwardly toward the center rail 336 such that tab 222 is captured between posts 338. The tapered rails 336 and shoulders 220 are dimensioned such that when the supplemental storage tray 300 is lowered into the non-essential area 710, the tapered rails 336 guide the supplemental storage tray 300 into the proper position. The tab 222 is also tapered, and as the supplemental storage tray 300 is lowered, posts 338 and tab 222 center the supplemental storage tray 300 above processors 105 and memory devices 110. With the supplemental storage tray 300 mounted in chassis 200, a gap 720 is formed between the bottom surface of the bottom plate 302 and the top of the processors 105 and memory devices 110.
The chassis 200 has walls 202, 204, 206 and 208 that define an interior cavity 212 within the chassis. A backplane 240 is mounted to a bottom wall 202 of the chassis and one or more processors 105 are connected to the backplane 240. A first storage device 120 is connected to the chassis and is communicatively coupled to the processor(s). A supplemental storage tray 300 has perimeter plates 302, 304, 306 and 308 that define a bay 312 within the supplemental storage tray. The supplemental storage tray 300 is suspended above the processor(s) 105 by at least one wall 208 of the chassis. A supplemental storage device 500 is disposed in the bay 312 and is communicatively coupled to the processor(s). The supplemental storage device 500 provides additional storage capacity to the information handling system 100.
The airflow movement devices 260 draw cooling air from the chassis front side 204 over the primary storage devices 120 and through airflow movement devices 260. The airflow through chassis 200 is then split into an upper airflow path 730 and a lower airflow path 740. The upper airflow path 730 flows through cooling passages 324 over supplemental storage devices 500 and out of cooling passages 322. The air flow continues over printed circuit boards 250 and exits chassis 200 at the rear side 206. The lower airflow path 740 flows through gap 720 and over and around processors 105 and memory devices 110. The air flow continues over printed circuit boards 250 and exits chassis 200 at the rear side 206. The supplemental storage tray 300 at least partially directs some of the air generated by the air flow movement devices 260 to flow through the gap 720.
The supplemental storage tray 300 is mounted into a non-essential area 710 within interior cavity 212 above processors 105 within the information handling system chassis 200, such that the supplemental storage tray 300 is suspended above the processors 105 and other functional components affixed to the backplane 240. The supplemental storage tray 300 has perimeter plates 302, 304, 306 and 308 defining a bay 312. At least one supplemental storage device 500 is secured in the bay 312. The at least one supplemental storage device 500 is communicatively coupled with the processors 105 to provide additional storage capacity within the electronic enclosure 200 beyond a storage capacity of the at least one first storage device 120.
FIG. 10 illustrates a flowchart of an exemplary method for increasing storage within an electronic enclosure chassis. Generally, method 1000 represents a method to increase storage capacity within an information handling system. In the discussion of FIG. 10, reference is also made to components illustrated in FIGS. 1-9. Method 1000 begins at the start block and proceeds to block 1002 where the supplemental storage tray 300 is formed with a bottom plate 302, a first side plate 308, a second side plate 308, a front plate 304 and a rear plate 306. At least one retention feature 316 is defined in the bottom plate (block 1004). At block 1006, at least one rail 336 is formed that extends from each of the side plates. A retention mechanism 360 is attached to the supplemental storage tray (block 1008). The retention mechanism is configured to selectively hold and release the supplemental storage device 500. A carrier 600 is affixed to the supplemental storage device 500 (block 1010). The carrier is engaged with the retention feature such that the carrier is held to the bottom plate (block 1012). At block 1014, the retention mechanism 360 is actuated to secure the carrier and the supplemental storage device in the supplemental storage tray bay 312.
At block 1016, the supplemental storage tray 300 is mounted into a non-essential area 710 within a cavity 212 above a processor 105 within an information handling system chassis 200, such that the supplemental storage tray is suspended above the processor and other functional components affixed to the backplane 240. The at least one supplemental storage device 500 is communicatively coupled with the processor 105 to provide additional storage capacity within the electronic enclosure beyond a storage capacity of the primary storage device 120 (block 1018). Method 1000 then ends.
The supplemental storage tray 300 and supplemental storage devices 500 advantageously replace a non-essential shroud mounted above the processor and memory devices providing additional storage capacity within the electronic enclosure 200. The supplemental storage devices 500 increase the storage capacity of IHS 100 to be greater than the storage capacity provided by the primary storage system devices 120 alone.
