Embodiment Construction

[0030] The present invention will be further described below in conjunction with drawings and embodiments.

[0031] image 3 It is a schematic diagram of a management system of an independent redundant disk array in a specific embodiment of the present invention. The system includes a storage control cabinet and at least two storage expansion cabinets, the storage control cabinet is connected to each storage expansion cabinet through an independent data channel; wherein, each storage expansion cabinet is provided with a predetermined number of Disk, the storage control cabinet is provided with a RAID controller, the RAID controller is used to select a predetermined number of disks in different storage expansion cabinets to be configured as a RAID group, and perform data read and write operations based on the configured RAID group.

[0032] The storage control cabinet is provided with a master RAID controller and a slave RAID controller, which are connected to each storage exp...

Abstract

The invention discloses a system and a method for managing RAIDs (redundant array of inexpensive disks), which are characterized in that the topological connection of a storage control cabinet and storage expansion cabinets is carried out by using a total exchange type framework, so that the problem in performance bottleneck especially between a plurality of storage expansion cabinets and the storage control cabinet of a disk storage system is solved. According to the system and the method for managing the RAID, for each group of RAIDs in an RAID deployment mode, the number of member disks is controlled effectively, so that each member disk is guaranteed to have an independent high-speed disk channel which is connected to the storage control cabinet and an RAID check disk; in this way, the overall operational performance of the RFID groups is guaranteed.

Description

technical field [0001] The invention relates to the technical field of disk storage system management, in particular to a management system and method for redundant array of independent disks (RAID). Background technique [0002] With the expansion of computing scale and the emergence of emerging application models (such as cloud computing, Internet of Things), big data applications are increasing day by day. Redundant Array of Inexpensive Disks (RAID, Redundant Array of Inexpensive Disks), as an independent large storage device, has been widely used in big data storage systems. The storage expansion cabinet is a cost-effective storage basic unit that is commonly used. It is generally connected to the storage control cabinet through FC or SAS cables, and the storage control cabinet performs RAID configuration management. [0003] In today's storage system construction, PB-level storage systems are very common. In high-performance computing and digital media environments, ev...
