Abstract
A storage controller includes a storage controller memory to store virtual disk metadata including an original stripe size (OSS) field and a logical stripe size (LSS) field, and a cache memory having an OSS buffer and a LSS buffer. The storage controller stores a first block size in the OSS field, configures a RAID array to provide storage blocks of the first block size based on the OSS field, stores a second block size in the LSS field, receives a first data transaction that includes a first data block of the second block size based upon the LSS field, maps the first data block from the second block size to the first block size, and executes the first data transaction on the RAID array using the first block size.
