Method and apparatus for improving disk array performance

摘要

A method and an apparatus for improving disk array performance relate to the technical field of computer systems. The method thereof comprises the following steps: setting a buffer between a disk array RAID and a disk block device; when write 10 is delivered to the disk array, temporarily saving data required by the disk array to the buffer; through organizing the data that is required by the disk array and temporarily saved by the buffer, providing corresponding query and update interfaces; and using the interfaces to perform query and update required by the write IO.

1. A method for improving performance of a Redundant Array of Independent Disks (RAID), comprising:
setting a cache between a RAID and a disk block; when a WRITE Input/Output (I/O) is issued to the RAID, temporarily storing data required by the RAID in the cache; providing an interface corresponding to search and update required for the WRITE I/O by organizing the data required by the RAID temporarily stored in the cache; and performing the search and update required for the WRITE I/O through the interface.
