SDS deployment method and system based on RAID

Abstract

The invention discloses an SDS deployment method and system based on the RAID. The method includes that physical nodes involving in deployment and provided with a disk array RAID card are determined; according to the requirement, according to the requirement, a magnetic disk in the physical nodes is set into an RAID mode with the redundancy function; software defined storage SDS is installed on the physical nodes; the magnetic disk set into the RAID mode is subjected to formatting through the SDS, and a single copy storage pool is built to provide storage service for users. According to the method and the system, consumption of resources such as CPUs, memory and networks is reduced, burden of CPUs, memory and networks is reduced, the I / O path is shortened and the I / O time delay is reduced.

Description

technical field [0001] The present invention relates to the technical field of storage, in particular to a RAID-based SDS deployment method and system. Background technique [0002] With the development of information technology, the amount of data is increasing. How to store these data has become an urgent problem for the entire IT industry. In the prior art, the software-defined storage deployment method is adopted, and SDS (Software Defined Storage, software-defined storage) software is installed on the physical nodes, and all hard disks on the physical nodes are uniformly managed from the software level, storage pools are deployed, and storage is provided externally. Serve. The storage pool sets corresponding redundancy rules so that the storage pool can provide intact storage services when certain hardware failures occur. [0003] The data redundancy of the storage pool completed by the traditional deployment method depends on the software layer, which has the followi...
