Abstract:
A method is used in managing mirroring in data storage system having a fast write device and a slow write device. A write I/O is received and is executed on the fast write device which includes a solid state drive. The write I/O is stored in interim storage having high performance sequential write capability. It is indicated that execution of the write I/O is complete. Based on the interim storage, the write I/O is executed on the slow write device.
