System and method of mirrored RAID array write management |
摘要 |
The write operations to the storage devices are managed so that the write operations that would force a storage device to reposition its read/write head outside its read optimization boundary are queued until a threshold is reached. Upon reaching the write queue threshold, the write operations are sent to the storage devices in a burst mode that limits the impact of storage device seek operations that force the device read/write head out of position relative to the data that is assigned as it's primary read region, keeping the read/write head in it's primary locality to optimize the performance of read operations.
