Distributed high performance pool

摘要

For a distributed high performance pool, the distributed high performance pool is provided with a fast rank. A management module promotes an extent from a storage pool to the distributed high performance pool in response to the extent satisfying promotion criteria. The distributed high performance pool and the storage pool are logically and physically distinct.

主权项

1. An apparatus comprising:
a distributed high performance pool (DHPP), wherein the DHPP is a solid-state device (SSD) rank; a processor; and a memory storing code executable by the processor to perform; promoting a first extent from a first storage pool to an allocation in the DHPP for the first storage pool in response to the first extent satisfying promotion criteria by modifying an extent address in pool metadata for the first extent to a physical address of the first extent in the DHPP and appending a DHPP reference to the pool metadata, wherein the first storage pool is a SSD rank and is assigned to a first customer, the pool metadata describes the first extent, and the promotion criteria are satisfied in response to a number of logical links to the first extent in the first storage pool exceeding a link threshold.
