Abstract: A method and apparatus for incremental RAID stripe update parity calculations. The method includes: receiving, at a first set of solid state drives, a last portion of a redundant array of independent disks (RAID) stripe among multiple portions of the RAID stripe, wherein the RAID stripe includes multiple shards, and wherein each previous portion of the RAID stripe is written to the first set of solid state drives; calculating a current parity value based on the last portion of the RAID stripe and a previous parity value updated after receiving each previous portion of the RAID stripe; and responsive to receiving all portions of a shard of the RAID stripe, copying the shard of the RAID stripe from the first set of solid state drives to a second set of solid state drives.

Abstract: In a storage system that includes a plurality of NVMe SSDs, data protection may be carried out by: for each of the plurality of NVMe SSDs, encrypting a device key using a master secret, wherein the device key, when not encrypted, is used to encrypt and decrypt data in one or more namespaces on the NVMe SSD; generating a plurality of shares from the master secret; and storing a separate share of the plurality of shares in a namespace prohibited from encryption on each NVMe SSD.

Abstract: Distributing management responsibilities for a storage system that includes a storage array controller and a plurality of storage devices, including: identifying a plurality of elements in the storage system; for each of the plurality of elements in the storage system, creating a distributed manager, wherein each distributed manager is configured for gathering information describing the state of the associated element in the storage system, determining an action to perform against the associated element in the storage system, and executing an approved action against the associated element in the storage system; and creating a distributed management hierarchy that includes each of the distributed managers.

Abstract: Continuous value data redundancy, including: receiving, by a storage system, a dataset; determining, based on a data resiliency metric, an integer redundancy value for the dataset from among a plurality of redundancy values; and generating, based on the integer redundancy value for the dataset, data recovery information for the dataset, wherein the integer redundancy value for the dataset is different from at least one other integer redundancy value for another dataset stored within the storage system.
