Abstract
Methods, systems, and computer program products for MLU replication, storage, and retrieval in a RAID environment are disclosed. According to one method, a data storage extent pool representing a portion of a RAID array is provisioned. A replica vault including a second data storage extent pool and representing a portion of a RAID array is provisioned. An MLU for allocating data storage extents from the data storage extent pool is created and, in response to a data write operation, a data storage extent from the data storage extent pool is allocated and data associated with the data write operation is stored in the data storage extent. The MLU is replicated to create a second MLU by allocating a second data storage extent in the second data storage extent pool in the replica vault and copying data stored in the data storage extent to the second data storage extent.
