Supported Arrays

Context

Resource provisioning is an available feature that allows large volumes to be initialized quickly.

A resource provisioned volume is a thick volume in an SSD volume group or pool, where drive capacity is allocated (assigned to the volume) when the volume is created, but the drive blocks are deallocated (unmapped). With a resource provisioned volume, there is no time-bound background initialization. Instead, each RAID stripe is initialized upon the first write to a volume block in the stripe

Resource provisioned volumes are supported only on SSD volume groups and pools, where all drives in the group or pool support the NVMe Deallocated or Unwritten Logical Block Error Enable (DULBE) error recovery capability. When a resource provisioned volume is created, all drive blocks assigned to the volume are deallocated (unmapped). Deallocating blocks can improve SSD wear life and increase maximum write performance. The improvement varies with each drive model and capacity.
