The ODX function of Windows Server 2012 or later offloads the processing load for copying and transferring
files from the CPU of the server to the storage system.
Thin Provisioning Space Reclamation
•
The Thin Provisioning Space Reclamation function of Windows Server 2012 or later automatically releases
areas in the storage system that are no longer used by the OS or applications. A notification function for the
host is provided when the amount of allocated blocks of the TPV reaches the threshold.
Hyper-V
