The hardware acceleration functionality works only if you use an appropriate host and storage array combination.

Table 1. Hardware Acceleration Storage Requirements

ESXi

Block Storage Devices

NAS Devices

ESXi version 6.0

Support T10 SCSI standard, or block storage plug-ins for array integration (VAAI)

Support NAS plug-ins for array integration

Note:

NFS 4.1 does not support hardware acceleration.

Note:

If your SAN or NAS storage fabric uses an intermediate appliance in front of a storage system that supports hardware acceleration, the intermediate appliance must also support hardware acceleration and be properly certified. The intermediate appliance might be a storage virtualization appliance, I/O acceleration appliance, encryption appliance, and so on.
