Storage Hardware Acceleration 24
The hardware acceleration functionality enables the ESXi host to integrate with compliant storage
systems. The host can offload certain virtual machine and storage management operations to the storage
systems. With the storage hardware assistance, your host performs these operations faster and
consumes less CPU, memory, and storage fabric bandwidth.
Block storage devices, Fibre Channel and iSCSI, and NAS devices support the hardware acceleration.
For additional details, see the VMware knowledge base article at http://kb.vmware.com/kb/1021976.

Hardware Acceleration Benefits
When the hardware acceleration functionality is supported, the host can get hardware assistance and
perform several tasks faster and more efficiently.
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 files
n
Provisioning thick virtual disks
n
Creating fault-tolerant virtual machines
n
Creating and cloning thick disks on NFS datastores
