Abstract

The invention relates to a method and device for initializing RAID. The method comprises the steps that a CPU receives an RAID establishing command sent by a client side; the CPU determines a plurality of target disks based on identification information of the target disks in the establishing command and constructs corresponding initializing commands for the target disks respectively based on hardware information of the target disks; the CPU sends the initializing commands to an initializing module based on an FPGA; the initializing module based on the FPGA receives the initializing commands issued by the CPU and constructs corresponding initial frames based on the initializing commands; the initializing module based on the FPGA sends the initial frames to the target disks respectively, so that the target disks are initialized based on the initial frames. According to the method and device, the initializing module based on the FPGA can directly interact with the disks, therefore, IO operation in most operation systems can be reduced, and the loads of the operation systems can be relieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for initializing a RAID (Redundant Arrays of Independent Disks, disk array). Background technique [0002] In order to ensure the availability of data and the performance of subsequent application access, RAID usually needs to be initialized before use. [0003] Taking software RAID as an example, in related technologies, software RAID can construct data according to the configuration command issued by the configuration client during initialization, and search for the target hard disk according to the constructed data, and then, software RAID can remove the target hard disk from the super block and All data outside the bitmap is cleared to complete the initialization. [0004] In related technologies, the data sent by the software RAID must pass through the operating system before being transmitted to the hard disk. After the data is sent, the ...
