Abstract: A system includes a solid-state storage array having a plurality of solid-state storage devices and a storage controller coupled to the solid-state storage array, the storage controller including a processing device, the processing device to select a segment height based on erase block sizes of the plurality of solid-state storage devices. The processing device is further to program a data segment using the segment height to a data stripe across two or more of the plurality of solid-state storage devices and store the segment height in metadata associated with the data segment.

Abstract: A method of using boot-time metadata in a storage system is provided. The method includes writing a fragmentation stride to a solid-state storage device of the storage system, the fragmentation stride defining a granularity on which fragmentation of erase blocks of the solid-state storage device occurs. The method includes allocating portions of erase blocks for at least one process in the storage system, in accordance with the fragmentation stride and writing boot up metadata at offsets that are based on the fragmentation stride, in the solid-state storage device.
