Abstract
A set of storage devices may interoperate to share a pool of storage space, such as in a Redundant Array of Inexpensive Disks (RAID) scheme. However, the details of the representation of the pool and the allocation of capacity to the pool may enable advantages and/or impose limitations on the storage set. Presented herein are techniques for generating a representing a pooled partition on one or more storage devices featuring a pool configuration representing the pool as a set of spaces manifested by the pool; a set of storage devices sharing the pool; and a set of extents that map physical areas of the storage devices to logical areas of the spaces. The flexibility of these pooling techniques may enable such features as flexible capacity allocation, delayed binding, thin provisioning, and the participation of a storage device in two or more distinct pools shared with different sets of storage devices.
