Typically, when you create a virtual disk on an NFS datastore, the NAS server determines the
allocation policy. The default allocation policy on most NAS servers is thin and does not guarantee
backing storage to the file. However, the reserve space operation can instruct the NAS device to use
vendor-specific mechanisms to reserve space for a virtual disk. As a result, you can create thick
virtual disks on the NFS datastore.

Native Snapshot Support. Creation of virtual machine snapshots can be offloaded to the array.
n
Extended Statistics. Supports visibility to space use on NAS devices. This functionality is useful for
thin provisioning.
With NAS storage devices, the hardware acceleration integration is implemented through vendor-specific
NAS plug-ins. These plug-ins are typically created by vendors and are distributed as VIB packages
through a website. No claim rules are required for the NAS plug-ins to function.
Several tools for installing and upgrading VIB packages are available. They include the esxcli
commands and vSphere Update Manager. For more information, see the vSphere Upgrade and Installing
and Administering VMware vSphere Update Manager documentation.
Install NAS Plug-In
Install vendor-distributed hardware acceleration NAS plug-ins on your host.
This topic provides an example for a VIB package installation using the esxcli command. For more
details, see the vSphere Upgrade documentation.
In the procedure, --server=server_name specifies the target server. The specified target server
prompts you for a user name and password. Other connection options, such as a configuration file or
session file, are supported. For a list of connection options, see Getting Started with vSphere Command-
Line Interfaces.
Prerequisites
Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started with
vSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.
Procedure
1 Place your host into the maintenance mode.
2 Set the host acceptance level:
esxcli --server=server_name software acceptance set --level=value
The host acceptance level must be the same or less restrictive than the acceptance level of any VIB
you want to add to the host. The value can be one of the following:
