Storage Hardware Acceleration 23
The hardware acceleration functionality enables the ESXi host to integrate with compliant storage arrays
and ooad specic virtual machine and storage management operations to storage hardware. With the
storage hardware assistance, your host performs these operations faster and consumes less CPU, memory,
and storage fabric bandwidth.
The hardware acceleration is supported by block storage devices, Fibre Channel and iSCSI, and NAS
devices.

Hardware Acceleration Benefits
When the hardware acceleration functionality is supported, the host can get hardware assistance and
perform several tasks faster and more eciently.
The host can get assistance with the following activities:
n
Migrating virtual machines with Storage vMotion
n
Deploying virtual machines from templates
n
Cloning virtual machines or templates
n
VMFS clustered locking and metadata operations for virtual machine les
n
Provisioning thick virtual disks
n
Creating fault-tolerant virtual machines
n
Creating and cloning thick disks on NFS datastores
