Problems solved by technology

[0006] The main purpose of the present invention is to provide a method for realizing the function of a hard RAID card based on FPGA, aiming at solving the problem that in the current RAID technology, replacing a faulty disk is usually performed manually by network administrators, and the operation steps are more complicated and time-consuming. Not only will it delay the progress of data storage, but it will also increase the risk of data loss in the entire storage system

Abstract

The invention discloses a method for realizing the function of a hard RAID card based on FPGA, which is applied to a system for realizing the function of a hard RAID card based on FPGA; the system includes an FPGA chip, a storage disk and application equipment; the PS terminal of the FPGA chip includes a software Core processor and memory unit, the PL end of described FPGA chip comprises RAID array controller; Described storage disk comprises main disk, spare disk and temporary disk; At least 3 described main disks are all communicatively connected to described FPGA chip so that Form a RAID array; the method for implementing the function of a hard RAID card based on FPGA proposed by the present invention no longer requires network managers to manually restore the RAID array, which greatly reduces the recovery time of the RAID array and reduces the failure of the RAID array. The adverse effect of delaying the progress of data storage reduces the data loss risk of the entire storage system.

Description

Technical field [0001] The present invention relates to the field of disk array, and more particularly to a method of implementing a hard RAID card function based on an FPGA. Background technique [0002] RAID is an abbreviation of English Redundant Array Of Independent Disks, translated into Chinese, is a separate disk redundant array, or an abbreviated disk array. Simply put, RAID is a hard disk group (physical hard disk) to form a hard disk group (logical hard disk) in different ways, providing higher storage performance and providing data redundancy than a single hard disk; The different ways of constituting the disk array are the RAID level (RAID Levels). [0003] Disk arrays can reduce data for redundant protection. Depending on the RAID level, it can tolerate the number of disables that can be failed. Taking RAID5 as an example, each disk in the disk array stores data and check values, and after any disk failure, it can be based on storage data and test value. The content ...
