A method, computer program product, and computing system for determining that one non-volatile random access memory (NVRAM) drive of a pair of NVRAM drives of a storage system is offline, thus defining an offline NVRAM drive and an online NVRAM drive. A virtual disk may be generated on a plurality of solid-state disks (SSDs) of the storage system. The contents of the online NVRAM drive may be copied to the virtual disk. The virtual disk may be exposed to the storage system as a representation of the offline NVRAM drive.

Techniques involve: determining a first group of storage disks, a use rate of each storage disk of the first group of storage disks exceeding a first threshold, the first group of storage disks comprising a first group of storage blocks corresponding to a first redundant array of independent storage disk (RAID); allocating a second group of storage blocks corresponding to a second RAID from a second group of storage disks, the second group of storage blocks having the same size as that of the first group of storage blocks, a use rate of each storage disk of the second group of storage disks being under a second threshold; moving data in the first group of storage blocks to the second group of storage blocks; and releasing the first group of storage blocks from the first group of storage disks. Thus, use rates of the storage disks become more balanced.

A technique for storage management involves: determining multiple source disk slices from a storage array that provides redundant storage, a current disk group where each of the multiple source disk slices is located being different from a target disk group where the source disk slice is specified to be located; determining multiple destination disk slices from the target disk group based on the multiple source disk slices, the multiple destination disk slices being used to replace the multiple source disk slices; and causing data to be moved to the multiple destination disk slices from the multiple source disk slices. Accordingly, such a technique may improve the reliability of a storage system.

Techniques involve determining the number of disks in a Redundant Array of Independent Disks (RAID) storage system, and the storage system comprises multiple types of mixed disks. The techniques further involve determining a target number of RAID sets to be allocated in the storage system according to the number of disks and a predetermined threshold, and then allocating the multiple types of disks to the RAID sets according to the target number and types of disks. Such techniques propose a way to allocate mixed disks to the corresponding RAID sets. When the RAID set grouping is performed to mixed disks of the storage system, the same type of disks are allocated in the same RAID set as much as possible, thereby improving the performance of the storage system.

A failed stripe is determined among the stripes, the failed stripe comprising a group of failed extents residing on a group of failed storage devices, respectively, a number of failed storage devices in the group being less than or equal to parity width of the storage system. Distribution of the group of failed extents in the failed stripe is obtained. A rebuild parameter for rebuilding data in the failed stripe is generated based on the obtained distribution. The generated rebuild parameter is stored for rebuilding the storage system. Accordingly, a rebuild parameter generated for one failed stripe is reused for other failed stripe with the same distribution. The performance of rebuild operations may be improved, and time of rebuild operations may be reduced.
