BACKGROUND
1. Field
The present disclosure generally relates to server system, and more particularly pertains to server system that has enclosure used to structurally support a load.
2. Related Art
In a conventional arrangement, server systems are usually mounted from the front of the server system rack like a drawer, and therefore it has been intuitive to arrange the majority of storage drives of the server systems at location(s) that is near a user for easy accessibility. In other words, the storage drives (e.g., hard drives) are usually arranged at the front part of the server systems, and therefore the storage drives are typically inserted or removed from a front face or a top face of the server systems. However, insertion from the front face of the server systems naturally limits the number of the storage drives by the front face area due to industrial specified width and height; insertion from the top face of the server systems requires the user to reach from above of the server systems while inserting or removing a storage drive, which is not convenient. On the other hand, insertion from the side faces of the server systems (e.g., the flank of the server system body) may increase the number of the storage drives as well as maintain easy accessibility to each storage drives. However, having more storage drives means more heat is produced within the server system. Furthermore, more storage drives under industrial specified width and height also means less available space for cooling. Therefore, side insertion of the storage drives usually has a thermal problem, which is highly undesirable to server systems.
The present disclosure provides a new arrangement of a side loading server system that incorporates enhanced heat management capability.

According to one embodiment of the present disclosure, FIG. 1 illustrates a server system 100 mounted to a rack 500; FIG. 2 illustrates an exploded view of the server system 100 without the rack 500; FIG. 3 illustrates the arrangements in the server system 100. Referring to FIG. 2 and FIG. 3, the server system 100 has an enclosure. The enclosure comprises a deck (base) 11, a top cover 12 disposed over the deck 11, a front panel 13 disposed between the top cover 12 and the deck 11, a back panel 14 parallel to the front panel 13, a pair of side walls 15 parallel to each other, two component housings (i.e., storage module)17, two circuit boards 18, a fan module 19, a pair of fan mounts 20, a board insulator 21, a motherboard (not shown), and a power module 22. In some embodiments, the enclosure further comprises two side doors 16 parallel to each other. In one embodiment, the deck 11 is a rectangular plate having two longer sides and two shorter sides. The front panel 13 and the back panel 14 are each arranged at one of the two shorter sides of the deck 11; the side walls 15 and the side doors 16 are arranged at the longer sides of the deck 11. Each longer side of the deck 11 has a side wall 15 proximal to the back panel 14 and a side door 16 proximal to the front panel 13. In some embodiments, the side doors 16 are mechanically attached to enclosure. In some embodiments, portions of the enclosure acts as a jambs to the side doors 16 where mechanical attachments are formed. In an exemplary embodiment, the side doors are hinged to the top cover 12 and configured to angle away from the enclosure. Furthermore, the side wall 15 and the side door 16 on the same side of the deck 11 are substantially aligned with each other. The side wall 15 and the side door 16 are disposed between the top cover 12 and the deck 11. The component housings 17, the circuit boards 18, the fan module 19, the board insulator 21, the motherboard, and the power module 22 are disposed on the deck 11. The component housings 17 comprises a receiving frame structure (storage case) 171, and a plurality of device docks (drive bays) 172. The device docks 172 are configured to carry a plurality of electronic devices (i.e., storage drives, storage components) D, and the storage drives D can be inserted into the receiving frame structure 171 horizontally with the device docks 172 from the front end of the component housing 17. In some embodiments, the component housing 17 is configured to receive the plurality of storage components D in a stacked array formation. In one embodiment, the device docks 172 can be integrated into the receiving frame structure 171, and thus the receiving frame structure 171 can receive the storage drives D by itself. Thus, the device docks 172 may be arranged in a stacked array formation as well. In some embodiments, the component housing 17 has a top surface and a bottom surface respectively fastened to the top cover 12 and the deck 11. In some other embodiments, the component housing 17 has a front end and a back end opposite the front end. The front end is facing outward the enclosure and the back end is facing inward the enclosure. In some embodiments, the component housing includes a main body where openings between the front end and the back end of the main body allow access between the front end and back end of the component housing. The component housings 17 are arranged between the side doors 16 in a back to back arrangement. Each of the component housings 17 is facing one of the side doors 16. In other words, the front end of the component housings 17 are facing outward from the longer side of the deck 11. The component housings 17 are at a distance from a periphery of the corresponding longer side of the deck 11. Since the component housings 17 are facing the side doors 16, the device docks 172 and the storage drives D cannot be removed from the receiving frame structure 171 when the side doors 16 are closed. In some embodiments, the front end of the component housing 17 is at a distance from the side door 16.
In some embodiments, the pair of circuit boards 18 are arranged between the pair of component housings 17. The pair of circuit boards 18 are at a distance from each other. Each of the circuit boards 18 is vertically arranged with respect to the deck 11 at the back end of one of the component housings 17, so the circuit boards 18 are standing behind and covering the back end of the component housings 17. In some embodiments, the circuit boards are covering the back end of the component housings by having the planar surface (i.e., side of the circuit board having the largest surface area) of the circuit board 18 arranged projectively within the periphery of the back end of the component housing 17. In some embodiments, the circuit board 18 may arranged to extend from the periphery of the back end of the component housing 17. In an exemplary embodiment, the planar surface of the circuit board 18 may be disposed over the opening at the back end of the main body of the component housing 17. In some embodiments, each of the circuit boards 18 may be arranged at an angle from the deck 11. In an exemplary embodiment, the circuit boards 18 are arranged to be substantially perpendicular to the deck 11. Further, the circuit board 18 may be abutting the back end of the component housing 17. In some embodiments, the circuit board 18 is mechanically fastened to the back end of the component housing 17. In some embodiments, the circuit boards 18 can be electrically coupled to the storage drives D in the component housings 17 without cables in between. Thus, in some embodiments, the storage drives D and the circuit boards are coupled to each other using board-to-board connectors. Further, the circuit boards 18 are configured to form electrical coupling between the storage drives D and the motherboard.
The fan module 19 is arranged between the side walls 15 and configured to cool the component housings 17 and the circuit boards 18. The pair of fan mounts 20 are arranged separately in proximity to different side walls 15, and the fan module 19 can be installed to the server system 100 by coupling to the pair of fan mounts 20. As such, the fan module 19 sits across the deck 11 in a side to side direction in the server system 100. The motherboard is arranged on the board insulator 21 between the fan module 19 and the back panel 14, and the motherboard is electrically coupled to the circuit boards 18, the fan module 19, and the power module 22. The power module 22 is arranged between the side walls 15 closer to the back panel 14 than the fan module 19, and the back of the power module 22 is aligned with the back panel 14, and thus the back panel 14 does not cover the back of the power module 22 as such. Therefore, the power module 22 can be removed from the server system 100 independently. The top cover 12 is disposed above the deck 11 over the component housings 17, the circuit boards 18, the fan module 19, the motherboard, and the power module 22. Therefore, the deck 11, the top cover 12, the front panel 13, the back panel 14, the side walls 15, the doors 16, and the power module 22 together form an enclosure accommodating the component housings 17, the circuit boards 18, the fan module 19, the fan mounts 20, the board insulator 21, and the motherboard.
In one embodiment of the present disclosure, the top cover 12 comprises a storage cover 121 covering over the component housings 17 and the circuit boards 18, a fan cover 122 covering over the fan module 19, and a motherboard cover 123 covering over the motherboard. Therefore, the component housings 17 with the circuit boards 18, the fan module 19, and the motherboard can be accessed individually from the top of the server system 100 for maintenance by removing corresponding portion of the top cover 12.
FIG. 4 is a top view of FIG. 3 and FIG. 5 is a simplified partial layout PL of FIG. 4 according to one embodiment of the present disclosure. Referring to FIG. 4 and FIG. 5, a cooling arrangement of the server system 100 in accordance to an embodiment of the instant disclosure (e.g., for the component housings 17 and the circuit boards 18 thereof) will be described below.
To cool the server system 100, the fan module 19 is configured to draw air into the server system 100 from the front panel 13 and blow air out of the server system 100 at the back panel 14. Between the front panel 13 and the back panel 14, the air driven by the fan module 19 flows through and cool the component housings 17 and the circuit boards 18. More specifically, as shown in FIG. 5, the air flows into a collecting space CS in the front panel 13 through multiple air inlets 133 of the front panel 13, and then the air exits the front panel 13 through multiple air outlets 134 at the sides of the collecting space CS. And then, the air flows into two periphery corridors (first corridors) FC between the front panel 13 and the component housings 17. In some embodiments, the periphery corridor FC is defined by a lateral separation between the front end of the component housing, one of the side door, and a portion of a stress distributing member 24. As shown in FIG. 5, the portion of the stress distributing member 24 arranged between side doors 16 and the component housing 17 form a seal for the periphery corridor FC. Further, the stress distributing member 24 forms a barrier between a front section and a rear section of the deck 11. The pair of periphery corridors FC refer to the space situated inside the doors 16 and in front of the component housings 17 as shown in FIG. 5, so each of the two periphery corridors FC is defined between one of the doors 16 and one of the component housings 17 facing the door 16. The server system 100 further comprises a stress distributing member (first support) 24 arranged at the end of the periphery corridor FC and on a side closer to the back panel 14 of the component housings 17, and the stress distributing member 24 acting as an air stopper is configured to stop the air in the periphery corridor FC from flowing toward the fan module 19 without passing through the component housings 17 and the circuit boards 18. In some embodiments, the air flowing though the periphery corridor FC is exhausted by the fan module 19 to enter the component housing 17 through the front end and exit the component housing 17 through the plurality of slits 181 of the circuit boards 18. The stress distributing member 24 traverses the entire width of the deck 11. In some embodiments, the stress distributing member 24 is fastened to the deck 11 and the top cover 12. The stress distributing member 24 and the component housing 17 are arranged to abut each other. In one embodiment, the server system 100 can comprise other types of air stoppers disposed at the end of the two periphery corridors FC instead of or in addition to the stress distributing member 24, for example, airtight sealant, airtight foam, airtight tape, etc. As a result, the air flows from the two periphery corridors FC into the component housings 17 through multiple air holes 1721 at the front end, and then the air leaves the component housing 17 from the multiple slits 181 on the circuit boards 18. As such, the air enters a central corridor (second corridor) SC which is a space defined between the circuit boards 18. As the fan module 19 continues drawing, the air from the central corridor SC is driven through an opening 243 of the stress distributing member 24 between the central corridor SC and the fan module 19. The opening 243 may be formed by a perforation on the stress distributing member 24 aligned with the central corridor SC. In the end, the air passes through the fan module 19 and leaves the server system 100 from the back panel 14. The two periphery corridors FC are parallel to the central corridor SC, whereas the collecting space CS is perpendicular to the central corridor SC. It should be noted that, the collecting space CS in the front panel 13 should not be in direct communication with the central corridor SC between the component housings 17.
FIG. 26A-26E illustrates a boning structure according to one embodiment of the present disclosure. In some embodiments, the enclosure is divided into a front section and a rear section. A boning structure of the enclosure is configured to provide structural support to the enclosure when experiencing load force. In some embodiments, the boning structure includes the stress distributing member 24, the side walls 15 fastened to the ends of the stress distributing member 24, and a spine 25 disposed between the deck 11 and the stress distributing member 24. The spine 25 may be disposed substantially equidistantly to the pair of side walls 15. In some embodiments, the stress distributing member 24 further includes a holding bracket 246 configured to hold down the spine 25 when experiencing load force. The holding bracket 246 forming an arch in the bottom part of the stress distributing member 24.
In addition to the stress distributing member 24 being arranged to define a rear section of the enclosure from the front section, the stress distributing member 24 may be used as a structural beam capable of withstanding load. In some embodiments, a server rack is configured to receive a plurality of enclosure. When a user need to access the enclosure, the user may pull the enclosure partially away from the server rack. In this way, a portion of the enclosure is without support from the rack. When in use, the enclosure may be partially hanging out of the server rack and may be without support for the front section. The stress distributing member is configured form a cantilever for the enclosure when a portion (i.e. front section) of the enclosure is hanging. The front section of the enclosure is defined by an area between the front panel 13 and the stress distributing member 24. In some embodiments, the component housings 17 are arranged in the front section of the enclosure. In this way, the center of gravity of the enclosure is positioned in the front section. In some embodiments, the stress distributing member 24 extends beyond the component housings 17. In some embodiments, ends of the stress distributing member 24 extending beyond the front end of the component housings act as air stoppers in the periphery corridor FC.
In some embodiments, the spine 25 may form a channel having a web 251 and flanges 252 protruding from sides of the web 251. In some embodiments, the web 251 traverses across the whole length of front section and extending partially into the rear section. Further, the web 251 is fastened to the deck 11. In some other embodiment, depending on the material of the spine, the web 251 may extent partially into the front section and the rear section. In some embodiments, the flanges 252 are extending towards the direction of the top cover 12. In some embodiments, the flanges 252 are mechanically fastened to the stress distributing member 24. Further, the ends of the flanges form L-channels 253. In some embodiments, the L-channel may be a structure where a pair of planar structures are arranged to form an L shaped cross section. In some embodiments, the angle between the planar structures may be perpendicular to each other. In some other embodiments, the angle between the planar structures may be less than 180 degrees. In an exemplary embodiment, the flanges 252 are mechanically fastened to a side of the stress distributing member 24 facing the front section. In particular, a portion of the L-channel 253 disposed parallel to a surface of the stress distributing member 24 are fastened to the stress distributing member 24 using a fastener 254. Further, in some embodiments, the flanges 251 are mechanically fastened to the front panel 13. In an exemplary embodiment, the flanges are mechanically fastened to the internal frame 132 of front panel 13. In particular, a portion of the L-channel 253 disposed parallel to a internal frame 132 are fastened to the stress distributing member 24 using a fastener 254.
Referring across the width of the stress distributing member 24, when a weight load of the storage devices is applied to the front section of the enclosure, the spine 25 may present a load force to the stress distributing member 24 and the side walls 15 may each present support reaction force to the ends of the stress distributing member 24. Referring across the length of the enclosure, when a weight load of the storage devices D is applied to the front section of the enclosure, the stress distributing member 24 and the spine 25 may form a cantilever structure. In an exemplary embodiment, when the storage devices D are equally divided between the pair of component housings 17, the storage devices D may exert substantially constant loading on the length of the spine disposed across the front section.
Furthermore, the side walls 15 are arranged on the rear section of the enclosure. The side walls 15 of the enclosure are abutting the ends of the stress distributing member. In some embodiments, the side walls 15, the deck 11, and the top cover 12 are fastened to the stress distributing member 24. In this way, the structural integrity of the enclosure is supported by the stress distributing member 24 and, further, by the spine 25. When a force is applied to any of the side walls 15, the deck 11, and the top cover 12, the stress distributing member 24 may absorb at least a portion of the stress generated on the enclosure by the force applied.
FIG. 27A-27B illustrates a side door structure according to one embodiment of the present disclosure. In further embodiments, a seal strip is disposed between the side door 16 and the jamb to the side door 16 on the enclosure. The seal strip is configured to prevent air from entering the side door 16. In some embodiment, the seal strip may be used as a barrier for the space between the jamb of the side door 16 and the side door 16. In an exemplary embodiment, the jamb of the side door 16 is a portion of the top cover 12. The seal strip is disposed between the side door 16 and the top cover 12. The seal strip is configured to prevent air from entering through a space between the side door and the top cover.
FIG. 6 illustrates the front panel 13 being disassembled according to one embodiment of the present disclosure. The front panel 13 comprises an external frame 131, and an internal frame 132 opposite the external frame 131. Multiple air inlets 133 are formed on the external frame 131 through perforations. Multiple air outlets 134 are formed on the internal frame 132 through perforations. The front panel 13 can be installed to the server system 100 by coupling the internal frame 132 between the side of component housings 17 and the deck 11. In other words, the component housings abut the internal frame. In some other embodiments, the component housing is further arranged to be fastened to the front panel 13. And, the external frame 131 is coupled to the internal frame 132 to form the collecting space CS. In some embodiments, the collecting space CS is formed between the external frame 131 and the internal frame 132. In some embodiments, the collecting space CS is arranged to collect particles from outside environment. However, the use of the collecting space CS is not limited thereto. The multiple air inlets 133 are arranged on the external frame 131. In addition, the multiple air inlets 133 comprise a major air inlet 133a arranged at the front of the front panel 13 and a minor air inlet 133b arranged at the top and/or at the bottom (not shown) of the front panel 13. In other words, the major air inlet 133a and the minor air inlet 133b are arranged at different faces of the front panel 13. The multiple air outlets 134 are arranged to the sides of the internal frame 132, and thus corresponding to the two periphery corridors FC in position. In some embodiments, the perforations (i.e., multiple air outlets 134) on the internal frame 132 are formed in an area projectively across the extending part of the stress distributing member 24. In particular, the multiple air outlets 134 are formed in an area of the internal frame 132 arranged between the front end of the component housing and the side door. In some embodiments, the area of perforation of the external frame is greater than an area of perforation of the internal frame. In comparison, the total area of the multiple air inlets 133 is larger than the total area of the multiple air outlets 134, as such compressing the air and increasing the flowrate around the multiple air outlets 134.
In one embodiment of the present disclosure, FIG. 7 shows the storage cover 121 comprising a cover punch 1211 if the minor air inlet 133b is arranged at the top of the front panel 13, and the cover punch 1211 is corresponding to the minor air inlet 133b in position. Therefore, the air can be drawn through the cover punch 1211 of the storage cover 121 that leads into the collecting space CS of the front panel 13. In another embodiment of the present disclosure, FIG. 8 shows the deck 11 comprising a deck punch 111 if the minor air inlet 133b is arranged at the bottom of the front panel 13, and the deck punch 111 is corresponding to the minor air inlet 133b in position. Therefore, the air can be drawn through the deck punch 111 of the deck 11 that leads into the collecting space CS of the front panel 13. Back to FIG. 7, in one embodiment of the present disclosure, each of the doors 16 comprises a stepped structure 163 which divides the door 16 into an upper portion 16U and a lower portion 16L, and the lower portion 16L is dented into the server system 100 with respect to the upper portion 16U. Therefore, the doors 16 are configured to receive racking rails 600 beneath the stepped structures 163 when the server system 100 is completely within the rack 500 as shown in FIG. 1, such that the overall weight of the server system 100 can be evenly distributed between the front panel 13 and the back panel 14 without fixing the racking rails 600 to the doors 16.
FIG. 9 is a side view of the server system 100 with the door 16 opened according to one embodiment of the present disclosure. The server system 100 depicted in FIG. 9 is a 2U rack mount server unit, and each receiving frame structure 171 of the two component housings 17 is configured to carry twelve device docks 172, hence twelve storage drives D as shown. Therefore, the server system 100 with two component housings 17 is configured to load twelve storage drives D on each side, and twenty-four storage drives D in total as such. In an exemplary, the enclosure may be able to twenty-four storage drives D, each weighing around 630 grams. In some embodiments, the enclosure is able to support around 15 kg worth of electronic device weight inserted into the enclosure. In particular, the boning structure of the enclosure allows the enclosure to support 15 kg worth of load while hanging from the server rack. Further, in some other embodiments, the boning structure of the enclosure allows the enclosure to support more than 15 kg worth of load in the front section while hanging from the server rack. Of which, other load source other than storage devices may be included. In some other embodiments, the enclosure may be able to support hanging load greater than 15 kg (i.e. front section having a load weight around 21 kg. However, the embodiments are not limited thereto. In some embodiments, the loading limit of the enclosure may be changed according to the size and material of the enclosure. The multiple air inlets 1721 are arranged at the front of the device docks 172 in the component housings 17. Since both the air outlets 134 and the air holes 1721 are in communication with the periphery corridors, and thus allowing the air drawn by the fan module 19 flows from the collecting space CS into the device docks 172. The length Ld of the doors 16 is equal to or longer than the length Ls of the component housings 17, that not only shields the component housings 17 from dust, but also ensures the periphery corridorsFC defined inside the doors 16 communicating all the air holes 1721 when the doors 16 are closed, such that all the air from the multiple air outlets 134 can flow into the component housing 17. Since the doors 16 should be longer than the component housings 17, the side walls 15 is not overlapped with the component housings 17. Though the length Ls of the component housing 17 is equal to the length of the receiving frame structure 171 in this embodiment. In another embodiment where a receiving frame structure 171 is not provided, the length Ls can represent an overall length of a plurality of storage drives D that is mounted to the server system 100 on one side.
According to one embodiment of the present disclosure, FIG. 10 illustrates one of the component housings 17 with a circuit board 18 behind; FIG. 10-1 illustrates a A-A cross-sectional view of FIG. 10; FIG. 11 illustrates one of the receiving frame structures 171. As shown in FIG. 10, the twelve storage drives D in the receiving frame structure 171 are arranged horizontally in a three (rows) by four (columns) arrangement. Referring to FIG. 11, the receiving frame structure 171 comprises three column partitions 1711 and a plurality of row rails 1712, and each column partition 1711 has a double layered structure with the plurality of row rails 1712 integrated thereon. Back to FIG. 10-1, as the air drawn from the periphery corridorsFC entering the component housings 17 via the air holes 1721 on the device docks 172, the air passes passages P next to the storage drives D. In one embodiment, the passages P are defined by spaces above the top of the storage drives D. When the air travels through the passages P, the air is in direct contact with the storage drives D, and thus taking heat away mostly from top of the storage drives D. After passing through the passages P, the air leaves the component housings 17 and enters the central corridor SC via slits 181 on the circuit boards 18 which are behind the component housings 17.
FIG. 28 illustrates a storage module according to one embodiment of the present disclosure. The storage module may be formed by the component housing 17 and the circuit board 18. In some embodiments, the circuit boards 18 are perforated to form a plurality of slits 181. The plurality of slits 181A may be formed on the planar profile of the circuit boards 18. In some embodiments, the plurality of slits are in an array 181A formation.

When the door 16 is closed, one seal 161 is arranged proximal to the deck 11, whereas the other seal 161 is arranged proximal to the top cover 12. In other words, one seal 161 is installed near the door hinge 162, while the other is installed away from the door hinge 162.
In one embodiment of the present disclosure, the plurality of storage drives D is 3.5-inch in size. A 3.5-inch storage drive usually outperforms a 2.5-inch storage drive in cache size, RPM (revolution per minute), maximum storage capacity, data transfer speed, and price. However, the 3.5-inch storage drive has a higher power consumption than a 2.5-inch storage drive, hence higher operational temperature. The high operational temperature in combination with the component housing 17 being tightly packed with the 3.5-inch storage drives D, cooling of the server system 100 becomes a very serious issue. According to a cooling test result shown in FIG. 24, the cooling arrangement in FIG. 5 cools the storage drives D in operation with a result of temperature difference at 2.9 degrees Celsius and highest temperature at 45.7 degrees Celsius between the storage drives D. The low temperature difference shows an even and balance cooling across the storage drives D, whereas the highest temperature being lower than 50 degrees Celsius satisfies the general industrial standard of being safe and stable. It should be noted that, the air flowing within the server system 100 between the fan module 19 and the front panel 13 is laminar flow, and the air flowing between the fan module 19 and the back panel 14 is turbulent flow, and the same cooling arrangement can be applied to the storage drives D in 2.5 inch, as long as the physical capacity of the receiving frame structure 171 occupied by the device docks 172 and the storage drives D is more than 70%.
Moreover, the weight of a 3.5-inch storage drive is approximately four times of the weight of a 2.5-inch storage drive. Therefore, carrying twenty-four 3.5-inch storage drives D at a front portion FP of the server system 100 as shown in FIG. 3 puts a lot of stress to the deck 11. FIG. 25 illustrates the server system 100 with a third support 27 according to one embodiment of the present disclosure. To further enhance the structural strength of the deck 11, the third support 27, other than the stress distributing member 24 and the spine 25, can be included in the central corridor SC and coupled between the stress distributing member 24 and the internal frame 132. However, the server system 100 can include at least one from the stress distributing member 24, the spine 25, and the third support 27 in any combination thereof according to one embodiment of the present disclosure.
It should be noted that, though all the exemplary illustrations are based on a 2U rack mount server, any embodiment of the present disclosure can be incorporated in any other rack mount servers with different dimension, such as 4U, 6U, and 8U rack mount servers.
