Abstract: An apparatus may include a redundant array of independent disks (RAID) array including a plurality of solid state drives (SSDs). The apparatus may further include a RAID array controller coupled to the plurality of SSDs. The RAID array controller may be configured to determine whether one or more logical block addresses (LBAs) of a stripe of the RAID array are unmapped. The one or more LBAs may be associated with one or more SSDs of the plurality of SSDs. The RAID array controller may be configured to determine data corresponding to the stripe based on the determination of whether the one or more LBAs are unmapped. RAID operations (such has Rebuild, Exposed Mode Read, and/or Parity Resync operations) may be optimized based on the knowledge of which LBAs are mapped and unmapped.

Abstract: Disclosed are embodiments for supporting dynamic tier remapping of data stored in a hybrid storage system. One embodiment includes a storage controller and firmware, where the firmware maintains a plurality of mapping elements, where each mapping element includes a plurality of group identifiers, where each group identifier is configured to indicate a mapping of a logical block addresses, and where the storage controller performs: receiving a read command including a logical block address; parsing the logical block address to determine a mapping element and a group identifier; determining, for a particular mapping element of the plurality of elements, whether the particular mapping element is locked, wherein the particular mapping element corresponds to the mapping element of the logical block address; and dependent upon the particular mapping element, queuing the read command for firmware processing or remapping the logical block address.

Abstract: Operating a RAID array with unequal stripes, the RAID array comprising N number of drives, where each RAID stripe includes P number of parity drives and N-P number of data drives, including buffering, by a RAID controller, write operations received from a host, each write operation specifying data to be written to the RAID array; distributing, by the RAID controller, the data to be written amongst N-P write groups, including: dividing the data into chunks of a sub-stripe size, wherein the sub-stripe size is less than a parity stripe size; and assigning the chunks, in round-robin order, to the N-P write groups; calculating parity from the N-P write groups; and writing the N-P write groups and the calculated parity as a first RAID stripe to the RAID array.

Abstract: Embodiments described herein include a PSL engine that includes various memory elements that permit the engine to grant locks on particular portions of data in a stripe in a RAID storage system. The PSL engine can assign (or lock) different blocks of the stripe for different operations. The PSL engine can grant locks to multiple operations for the same stripe if the operations access mutually exclusive blocks of the stripe. Each time a new operation is requested, the PSL engine determines whether the operation would affect a stripe data block that is currently assigned to another operation. If the new operation corresponds to a block of data in the stripe that includes data locked by another operation, the PSL engine assigns the new operation to a wait list. In one embodiment, the PSL engine maintains a wait list for each of the stripes in the RAID system.
