RAID CONTROLLER FOR RAID LEVEL 5 ACCELERATION BY USING THE PARITY CACHE AND METHOD THEREOF

摘要

PURPOSE: a kind of RAID (Redundant Array of Inexpensive Disc RAID level) control devices 5 accelerate to provide using parity cache a kind of improve data transfer speed and input/output number it is per second. ;CONSTITUTION: a kind of parity cache memory (122) includes binary cell and parity cell. The binary cell stores previous parity information. The parity cell includes XOR gate. If parity information inputs, execution is stored in binary cell to the XOR gate XOR parity informations and previous parity information that newly input, and stores the result into binary cell. A kind of parity cache controller (121) control parity cache memory. ;The 2012 of copyright KIPO submissions
