XIV storage systems
Abstract: With the release of IBM XIV Storage System Gen3 11.2.x microcode, customers can begin to capitalize on the highly awaited space reclamation benefits associated with Small Computer System Interface (SCSI) UNMAP support. While the IBM XIV supports SCSI UNMAP commands for both thick and thin provisioned volumes, only the latter use case is presented in this white paper since SCSI UNMAP benefits are typically associated with over-provisioned storage. For Microsoft data centers struggling to mitigate explosive data propagation, SCSI UNMAP is a valuable option to help control storage sprawl. Furthermore, SCSI UNMAP functionality is native to Windows Server 2012 which also offers new thin provisioning developments and supplemental operating system (OS) space reclamation features.
