Abstract: Administering storage access in a cloud-based storage system includes: acquiring, by a first storage controller, in response to a protocol request for exclusive access to an area of storage, a first lease for the area of storage of the cloud-based storage system; and storing, by the first storage controller, a first identifier for the first lease in a predefined portion of the area of storage, where the predefined portion of the area of storage is accessible to a second storage controller.

Abstract: Incremental RAID stripe update parity calculation includes: receiving a first portion of data of a RAID stripe for writing to a first memory location of a plurality of solid state drives; calculating a first parity value for the first portion of data of the RAID stripe; receiving a second portion of data of the RAID stripe for writing to a second memory location that is different from the first memory location; calculating a second parity value in dependence upon the second portion of the data of the RAID stripe and upon the first parity value; and responsive to successfully writing the second portion of data of the RAID stripe, replacing the first parity value with the second parity value.

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.

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.
