The hardware acceleration functionality enables your host to offload specific virtual machine and storage management operations to compliant storage hardware. With the storage hardware assistance, your host performs these operations faster and consumes less CPU, memory, and storage fabric bandwidth.

To implement the hardware acceleration functionality, the Pluggable Storage Architecture (PSA) uses a combination of special array integration plug-ins, called VAAI plug-ins, and an array integration filter, called VAAI filter. The PSA automatically attaches the VAAI filter and vendor-specific VAAI plug-ins to those storage devices that support the hardware acceleration.

To view and manage the VAAI filter and VAAI plug-ins available on your host, use the vSphere CLI commands.

For descriptions of the commands, see the vSphere Command-Line Interface Installation and Scripting Guide and the vSphere Command-Line Interface Reference.
