摘要: A disk cache operation which was optimized so as to adapted an form of the user and a array is executed. mechanism provided for each two sets controllers can be made operative in either one reliability significance mode storing same data into system, performance independently every average both said modes. process operates RAID0, RAID1, RAID3, or RAID5 set target efficiently Effective prepared on block enable access like RAID3 such that parity calculated without needing read even RAID5.
