Problems solved by technology

[0006] In the current RAID storage system, the logic and timing of starting up are all implemented manually, and the process of starting, restarting and shutting down the device is very complicated.
Any operation error may lead to serious consequences
Moreover, if the device loses power, when it is automatically powered on again, the startup sequence of the device is in an uncontrollable state, which poses a potential threat to the operation of the device

Abstract

The invention discloses a startup and shutdown time sequence control device for a magnetic disk array storage system. The device comprises a head controller and extension cabinet controllers, wherein the head controller is arranged in a PCI (Peripheral Component Interconnect) slot of the head, and comprises an input interface for receiving input and an output interface for outputting a command, and the output interface comprises a head sub-interface outputting a command to the head and an extension cabinet sub-interface for outputting the command to extension cabinets; the extension cabinet controller is arranged in each extension cabinet respectively, and the extension cabinet controllers are connected one another in a cascade mode; each extension cabinet controller comprises an input end and an output end, the input end of the primary extension cabinet controller is connected to the extension cabinet sub-interface of the head controller, input ends of other stages of extension cabinet controllers are connected to the output end of the previous extension cabinet controller, the output end of the last stage of the extension cabinet controller is vacant, and output ends of other stages of extension cabinet controllers are connected to the input end of the next stage of the extension cabinet controller respectively.

Description

technical field [0001] The invention relates to a disk array storage system, in particular to a power-on / off sequence control device for an independent redundant disk array. Background technique [0002] Redundant Array of Independent Disks (Redundant Array of Independent Disks) is referred to as RAID disk array. It combines N hard disks into a virtual single large-capacity hard disk through RAID Controller (hardware, software). Its feature is that N hard disks can simultaneously read Speed ​​up and provide fault tolerance (Fault Tolerant). [0003] RAID brings great benefits to the storage system (or the built-in storage of the server), among which improving the transmission rate and providing fault tolerance are the biggest advantages. RAID increases the transfer rate by using multiple disks simultaneously. RAID can greatly improve the data throughput (Throughput) of the storage system by simultaneously storing and reading data on multiple disks. In RAID, many disk driv...
