This application is a continuation application of PCT/CN2008/072501, filed on Sep. 24, 2008, which claims priority to Chinese Patent Application No. 200720195101.4, filed with the Chinese Patent Office on Nov. 5, 2007 and entitled “Rear Board of Blade Server, Blade Server and Subrack”, both of which are incorporated herein by reference in their entireties.
The disclosure relates to the field of blade server, and in particular, to rear board of blade server, blade server and subrack.
In the field of blade servers, the standard of Advanced Telecommunications Computing Architecture (ATCA) is a structure standard of the blade server based on a high performance of backplane. The standard of the ATCA defines standards of power in the blade server equipment and slots supplied power by the power, standards of a specification of subrack and connection between the subracks, a standard of interface and electrical connection connector, standards of exchange network and interface of the backplane, and so on. Each connector of hardware structure in the blade server is compact, consuming less energy, and occupying less space. The blade server has a better expandability, universality and interchangeability, and a better prospect in the telecom field. Suppliers such as SUN, Intel, and Motorola all provide blade servers having an ATCA structure.
With the development of the hardware, performance of the CPU becomes better and better, power consumption of the CPU is increasing accordingly. The power consumption of the CPU in the blade server is up to 95 W, and probably even to 120 W in the future, so that it becomes a challenge to design a board which can effectively dissipate heat. The ATCA structure of the conventional blade server has a compact structure. The width of the slot of each board is 1.2 inches. Superpower CPU, high capacity random-access memory (RAM), hard disk and interfaces are deployed on the board in a limited space, and it is required to meet the heat dissipation and layout of the hardware. The conventional blade server defined in the standard of ATCA may not satisfy the superpower CPU in structure, and the space of physical structure in the blade server equipment is a bottleneck for the blade server. Therefore, the ability to effectively dissipate heat in the blade server needs further study.
As can be seen from the above description that, the heat dissipation of the front board of the blade server is poor, and the structure of the blade server does not support the use of superpower CPU, and therefore, both the performance and reliability of the blade server are poor.
Embodiments of the present disclosure provide a rear board of a blade server, a blade server and a subrack, so as to improve heat dissipation, support the use of a superpower CPU, and improve the performance and reliability of the blade server.
A rear board of a blade server is provided in an embodiment of the present disclosure. The rear board includes a connector configured to connect hard disks, and a portion of the rear board on which the connector is set is extended outward so as to accommodate at least two hard disks, and the two hard disks are connected to the connector.
A blade server is also provided in an embodiment of the present disclosure. The blade server includes a front board and a rear board, wherein the rear board includes a standard Advanced Telecommunications Computing Architecture (ATCA) interface, and the rear board is connected to the front board through the standard ATCA interface, a connector configured to connect hard disks is set on the rear board, and a portion of the rear board on which the connector is set is extended outward so as to accommodate at least two hard disks, and the two hard disks are connected to the connector.
A subrack is also provided in an embodiment of the present disclosure. The subrack includes a power supply, a fan and a blade server, wherein the power supply is configured to provide power for the blade server, the fan is configured to dissipate heat from the blade server, the blade server includes a front board and a rear board, and wherein the rear board is connected to the front board through a standard Advanced Telecommunications Computing Architecture (ATCA) interface, a connector configured to connect to hard disks is set on the rear board, and a portion of the rear board on which the connector is set is extended outward so as to accommodate at least two hard disks, and the two hard disks are connected to the connector.
Embodiments of the present disclosure may provide at least the following exemplary benefits:
(i) Because the portion of the rear board defined in the standard of the ATCA is extended, the two hard disks are set on the rear board to achieve data backup between the two hard disks and hot plug, and the reliability of the data backup and maintainability of the blade server may be improved.
(ii) In addition, two hard disks set on the front board can be removed and set on the rear board of the blade server according to the embodiments of the present disclosure, so that a large amount of dissipating space is reserved on the front board. This greatly increases the dissipating ability of the front board. A superpower of CPU may be used in the blade server, so as to increase the performance of the blade server. For example, power consumption of the CPU used in the blade server according to the embodiments of the present disclosure may be 95 W, and the ability of dissipating of each slot in the blade server may be 300 W.
(iii) Moreover, because the rear board in the embodiments of the present disclosure is adapted to the standard interface of ATCA, the rear board of the blade server could be compatible with diverse subracks, so that this may improve the compatibility of the blade server, and this enables products of various manufactures to be interoperable.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate some embodiments and together with the description, serve to explain the principles of the embodiments disclosed herein.
In order to use a superpower CPU to improve the performance of a blade server product, the structure of the ATCA may be extended. In order to support two or more hard disks to be used and arranged on the blade server, a rear board of the blade server is provided according to the disclosed embodiments, a portion of the rear board is extended outward to accommodate at least two hard disks, and a connector of the two hard disks is set on the rear board, so that the hard disks are set on the extended portion of the rear board through the connector of the two hard disks. Therefore, there is no need to set the hard disks on the front board when using the rear board of the blade server according to some embodiments. Furthermore, in order to conform to the ATCA standard, ATCA standard interfaces are still applicable to be used as the interfaces of a rear board after a portion of the rear board is extended.
The rear board 21 as shown in
Preferably, slots of the hard disks are set on the extended portion of the rear board 21 (not shown in
Preferably, as shown in
Preferably, in consideration of the dimension of the hard disks and the extended portion, a plurality of connectors may be set at proper position on the rear board. Each connector is connected to a hard disk, so as to ensure that multiple hard disks to be connected may be accommodated on the rear board, achieve data backup between the two hard disks, and improve the reliability of the data backup.
Preferably, the hard disks set on the rear board are hot pluggable.

For example, power consumption of the CPU used in the blade server according to the embodiments of the present disclosure may be 95 W, and the ability of the heat dissipation of each slot in the blade server may be 300 W.
Because the rear board in some embodiments of the present disclosure adopts the standard interface of ATCA, the rear board of the blade server could be compatible with diverse subracks.
A subrack is also provided corresponding to a blade server provided according to some embodiments. As shown in
The power supply 401 is configured to provide power for the blade server 403, and the fan 402 is configured to dissipate heat for the blade server 403. The blade server 403 includes a front board and a rear board, wherein, each rear board includes a standard ATCA interface, and the front board is connected to the rear board through the standard ATCA interface. Hard disk connectors are set on each rear board, and a portion of the rear board on which the hard disk connectors are set is extended outward so as to accommodate at least two hard disks.
