Control method for storage system disk order

Abstract

The invention discloses a control method for a storage system disk order and relates to the field of computer technology. According to the condition that a storage server contains multiple Expander boards, by modifying a storage system SAS card and FW of the Expander boards, the SAS card is controlled to fixedly send a first SMP command to a port0 first, then each interaction is controlled in the FW of the Expander boards, and the Expander boards respond to the SAS card according to fixed time; the interactive process of the port0 is started first and ended first; the interactive process of a port1 is started later and ended later; and the process of recognizing hard disks according to a correct disk order is completed to ensure that the disk order is correct under a starting item menu and an operating system. Through the control method, the disk order is controllable under multi-backboard configuration, and it is convenient to flexibly correct the disk order according to configuration alternation; the hard disk order is correct, and convenience is brought to usage and maintenance; and it is not needed to modify hardware, so that cost is low.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for controlling disk sequence of a storage system. Background technique [0002] With the development of the Internet, cloud computing, and mobile communication technologies, data has become an indispensable and important asset for people and plays an important role in people's lives. The amount of global data is growing at an average annual growth rate of 50%, and 80% of the current total data is generated in the past two years. Big data is affecting all aspects of life. [0003] The server is the center of processing big data, from which effective information is extracted to serve real life. Currently, servers supporting mass storage are a new direction for server development. It plays a vital role in the development of cloud computing and big data. Massive data inevitably means a large number of hard disks, and the disk sequence control of a large number of hard ...

AI Technical Summary

Problems solved by technology

During production, hard disks are inserted one by one in sequence or the disk sequence is controlled by controlling the sequence of power supply. The execution efficiency is low, and operation errors are prone to occur, which is not convenient for large-scale production and use.

It can be seen that in a server with multiple hard disk backplanes, it is often difficult to fix the disk sequence between the hard disk backplanes. The sequence will vary with the software load when the SAS card recognizes the backplane. Use brings a lot of inconvenience
