System and method for synchronizing mirrored and striped disk writes

摘要

A system and method for synchronizing mirrored and striped disk writes. A data storage system may include a client computer system coupled to a first data storage device and a second data storage device and configured to transmit a first data write request. The first storage device may be configured to transmit a sequence number to the client computer system in response to receiving the first data write request. The client computer system may be further configured to transmit a second data write request including the sequence number to the second storage device. The second data storage device may include a counter and is configured to compare a current counter value to the sequence number. If the counter value is equal to the sequence number, the second storage device stores the data bytes corresponding to the second data write request and increments its counter.
