Abstract: A method of using flash storage devices with different sized erase blocks is provided. The method includes allocating a plurality of erase blocks of heterogeneous erase block sizes to a RAID stripe, to form a tile pattern having the heterogeneous erase block sizes in the RAID stripe. The method includes writing the RAID stripe across the flash storage devices in accordance with the allocating, and stopping the writing the RAID stripe, responsive to contents of the RAID stripe reaching a threshold.

Abstract: Maintaining data associate with a storage device is described. A method may include receiving, by an application executed by a storage array controller of a host server of a solid-state storage array comprising a plurality of solid-state storage devices, an indication of a change in state of a solid-state storage device of the plurality of solid-state storage devices. In response to receiving the indication, the method may also include retrieving a plurality of tables stored at a volatile memory of the solid-state storage device, the plurality of tables comprising information associated with characteristics of a plurality of data blocks of the solid-state storage device. The method may also include identifying one or more rules associated with the plurality of tables and creating, by the storage array controller, a new plurality of tables based on the one or more rules.

Abstract: An indication of a power-up of a storage device may be received. In response to receiving the indication, a first data structure that is stored at a volatile memory of the storage device may be retrieved. The first data structure may include first information associated with characteristics of a plurality of data blocks of the storage device. A second data structure stored at a non-volatile memory of the storage device may be retrieved where the second data structure includes second information associated with the characteristics of the plurality of data blocks of the storage device. A new data structure may be created based on the first information and the second information and a rule where an entry of the new data structure is provided a value from one of the first information or the second information based on the rule.
