Management of Storage Resources Allocated from Non-volatile Memory Devices to Users

Abstract:

A computer having a plurality of accounts and a storage device having a host interface, a controller, non-volatile storage media, and firmware. Each account has a namespace identifier that identifies the allocation of a portion of the non-volatile storage media to the account. The storage device stores a namespace map that defines the mapping between the logical addresses in a namespace identified by the namespace identifier and the logical addresses, in a capacity of the storage device, that correspond to the portion of the non-volatile storage media allocated to and accessible to the account. The account accesses the portion of the non-volatile storage media via the logical addresses in the namespace. The firmware of the storage device configures the controller to convert, using the namespace map, the logical addresses in the namespace to the physical addresses of the portion of the non-volatile storage media.
