Four-subnode star server system capable of realizing hard disk sharing

Abstract

The invention discloses a four-subnode star server system capable of realizing hard disk sharing, and relates to the field of high-density servers. The system mainly comprises four server nodes, a hard disk module, a power panel and a system middle board, wherein the hard disk module comprises a hard disk backboard and hard disks inserted into the hard disk backboard; the power panel is communicated with the system middle board to supply power to the system middle board; the hard disk module and the four server nodes obtain electricity from the system middle board; a SAS (Serial Attached SCSI) exchange board is arranged between the system middle board and the hard disk module and obtains the electricity in the system middle board; and through a SAS exchange board server node, any hard disk in the hard disk module can be accessed. In the four-subnode star system, the read-write access of any node to 24 pieces of 2.5-inch hdds (Hard Disk Drives) can be realized, the pooling and the sharing of system storage resources can be realized, the use ratio of the hard disk storage space of the four-subnode star server system is improved, and the stable and quick operation performance of the system is improved.

Description

technical field [0001] The invention relates to the field of high-density servers, in particular to a four-star server system for realizing hard disk sharing. Background technique [0002] With the continuous increase of Internet business volume, the storage capacity of data center network data has become a bottleneck restricting business development. Some network operators, in order to meet business needs, have to invest huge sums of money to rebuild new and larger data center rooms. In order to save costs, some other network operators can only take the method of making full use of the existing computer room space, and increase the data processing capacity of the server system occupying limited space as much as possible, so as to temporarily meet the development needs of their own business. In order to meet the needs of such customers as much as possible, different forms of high-density server systems have emerged as the times require. [0003] The usual server structure ...

Problems solved by technology

However, the hard disk storage subsystem that works with server nodes cannot be shared. For example, a four-star server system supports 24 pieces of 2.5”hdd, and each server node can only be used with 6 pieces of 2.5”hdd

When the four-star server system runs the user's business, some nodes may have a large amount of data access, while some nodes have a small amount of data access, which will cause the storage space of the server node with a large amount of access to be limited, affecting Good operation of the whole server system
