ABSTRACT:
A method of dynamic allocation of non-volatile memory in a cache storage subsystem includes constraining a redundant array of independent disks (RAID) 6 array in an unavailable state, the RAID 6 array having been newly created in the subsystem, destaging data from a write cache to a storage medium to free memory space, reserving the freed memory space for allocation to data-persistent storage, allocating the memory space to an adapter in the subsystem as a target for data in the event of a power loss, and changing the RAID 6 array to an available state. A system for dynamic allocation of non-volatile memory in a cache storage subsystem includes a computer processing device which constrains a newly-created redundant array of independent disks (RAID) 6 array in an unavailable state to execute a reconfiguration method.
