ABSTRACT:
Disclosed are methods, systems, and computer program products for dynamic mapping of logical unit (LUN) storage extents in a redundant array of inexpensive disks (RAID) environment. According to one method, a data storage extent pool representing at least a portion of a RAID array and including at least one data storage extent is provisioned. A first mapped logic unit (MLU) for allocating data storage extents from the data storage extent pool is created. A first data storage extent is allocated, using the first MLU, in response to a data write operation.
