摘要
Methods and apparatus for cut-through cache memory management in write command processing on a mirrored virtual volume of a virtualized storage system, the virtual volume comprising a plurality of physical storage devices coupled with the storage system. Features and aspects hereof within the storage system provide for receipt of a write command and associated write data from an attached host. Using a cut-through cache technique, the write data is stored in a cache memory and transmitted to a first of the plurality of storage devices as the write data is stored in the cache memory thus eliminating one read-back of the write data for transfer to a first physical storage device. Following receipt of the write data and storage in the cache memory, the write data is transmitted from the cache memory to the other physical storage devices.
