Problems solved by technology

[0002] A traditional local storage server usually concentrates a central processing unit (Central Processing Unit, CPU), a mechanical hard disk (Hard Disk Drive, HDD), a solid state disk (Solid State Disk, SSD), etc. in a single physical chassis, usually in different The server is designed to meet the differentiated requirements of different applications for capacity, bandwidth, and the number of read and write operations per second (Input / output Per Second, IOPS), and cannot be flexibly expanded to meet different application requirements
In addition, local storage resources are prone to underutilization, and these surplus storage resources cannot be efficiently shared with other computing resources.

Abstract

The invention provides a server, which comprises a calculation resource node, a storage resource node and an SAS (serial attached small computer system interface) switch, wherein the calculation resource node and the storage resource node are respectively connected with the SAS switch, and are physically separated. The server has the advantages that a storage resource can be statically or dynamically distributed to one or a plurality of calculating resource nodes by using a single disc as granularity, so pooling sharing of the storage resource is realized, and the resource utilization rate is improved; the server can be flexibly expanded.

Description

technical field [0001] The present invention relates to the technical field of computing and communication, in particular to a server. Background technique [0002] A traditional local storage server usually concentrates a central processing unit (Central Processing Unit, CPU), a mechanical hard disk (Hard Disk Drive, HDD), a solid state disk (Solid State Disk, SSD), etc. in a single physical chassis, usually in different The server is designed to meet the differentiated requirements of different applications for capacity, bandwidth, and the number of read and write operations per second (Input / output Per Second, IOPS), and cannot be flexibly expanded to meet different application requirements. In addition, local storage resources are prone to underutilization, and these surplus storage resources cannot be efficiently shared with other computing resources. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related a...
