Abstract

The application provides an input and output IO backplane and a configuration method and device for the IO backplane. The input and output IO backplane includes: A card slot for accommodating a redundant array of independent disks RAID card and B expansion chips, A and B All are integers greater than or equal to 2; wherein, each RAID card accommodated in the card slot is connected to each of the B expansion chips to access M hard disks through the B expansion chips ; Wherein, each of the expansion chips is connected to M hard disks, and at least one of the multiple connections in each of the hard disks corresponding to the B expansion chips is an active connection, and M is greater than or An integer equal to 2, so that when switching between a single RAID card and two RAID cards, the switching efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of computer storage, and in particular to an input / output IO backplane and a configuration method and device for an IO backplane. Background technique [0002] In view of the customer's different requirements for the server, the configuration on the input and output (Input Output, IO) backplane of the server is also different. For example, when the customer requires high bandwidth performance of the server hard disk, it is necessary to configure two types of IO backplane Redundant Array of Independent Disks (Redundant Array of Independent Disk, RAID) card to meet the demand for bandwidth performance. When the customer has a high price requirement for the server hard disk, it is necessary to configure a RAID card on the IO backplane to meet the price requirements. Requirements. Among them, RAID is a hard disk group (logical hard disk) formed by combining multiple independent hard disks (physical har...
