Abstract
Handling a write operation to write data to a section of a storage device includes determining if the section needs to be copied to at least a first target device and, if the section of the storage device needs to be copied to the at least first target device, providing the data to a memory location and confirming completion of the write operation prior to copying the section of the storage device to the at least first target device. Handling a write operation to write data to a section of a storage device may also include determining if a slot in a cache memory corresponding to the section of the storage device needs to be copied to at least a second target device. If so, then in some cases the slot may be copied to the at least second target device prior to providing the data to the memory location.
