Embodiment Construction

[0011] like figure 1 As shown, all the computing blades 3 in the blade server are connected to the middle board 4, and the SAS signal output of each computing blade is respectively connected to the independent interface on the middle board, and there is a SAS on the other side of the middle board that connects all the computing blades The 96pin connector for centralized signal output, the memory card 1 is connected to the 96pin connector on the middle board through the connector, and the other end of the memory card is connected to the hard disk unit 2 through the Mini SAS cable 6, the hard disk unit is composed of multiple hard disks, each Each hard disk is independently connected to the SAS backplane 5. Connectors are installed on the other side of the SAS backplane. Each connector leads to a Mini SAS cable. Each MiniSAS cable can control the signals of four hard disks. Therefore, the connection The number of connectors depends on the number of hard disks, and there are the ...

Abstract

The invention discloses a storage expanding module for a blade server and particularly relates to a storage expanding module having a sharing function. The transmission signal of the storage expanding module is connected with a blade by a middle plate, and simultaneously the blade and the storage expanding module are powered by the middle plate respectively and the blade and the storage expanding module are not mutually affected. Because the storage expanding module is used as big storage equipment, the storage capacity of the blade server is improved; by using an SAS control chip, the blade and the hard disk are separated, the hard disk can exist without relying on the computing blade, and only the SAS control chip needs to be configured when the storage capacity of the blade needs to be expanded, so that the capacity expansion of the corresponding computing blade can be realized; and the SAS control chip is configured by the CMM, and the configuration mode is flexible and diversified; and simultaneously, both the whole storage module and single hard disk support the hot-plugging, so that the problem of under storage capacity of the conventional blade server is solved, and the future maintenance is quick and convenient.

Description

technical field [0001] The invention relates to a blade server, in particular to a shared extended storage module for all computing blades in the blade server. Background technique [0002] Various blade server products currently on the market, due to their compact structure and limited space, the storage capacity of the blade server system is relatively low. Generally, each blade of a blade server is connected to a hard disk, and firstly connect the blade to the The hard disk is used as its storage space. Due to the large size of the hard disk, it will affect the heat dissipation of the blade, and the area of ​​the blade is limited by the rack. Usually, only two hard disks can be installed on one blade. To achieve redundancy of hard disk data, two hard disks are usually configured as RAID1, that is, two hard disks are mirrored, so that the usable storage space is equivalent to the capacity of one hard disk, but in this case the utilization rate of the hard disk is only 50%....
