<strong>vSphere</strong> <strong>Storage</strong><br />
Typically, when you create a virtual disk on an NFS datastore, the NAS server determines the allocation<br />
policy. The default allocation policy on most NAS servers is thin and does not guarantee backing storage<br />
to the file. However, the reserve space operation can instruct the NAS device to use vendor-specific<br />
mechanisms to reserve space for a virtual disk. As a result, you can create thick virtual disks on the NFS<br />
datastore.<br />
n Lazy file clone. Allows <strong>VMware</strong> View to offload creation of linked clones to a NAS array.<br />
n Extended file statistics. Enables storage arrays to accurately report space utilization.<br />
With NAS storage devices, the hardware acceleration integration is implemented through vendor-specific NAS<br />
plug-ins. These plug-ins are typically created by vendors and are distributed as VIB packages through a web<br />
page. No claim rules are required for the NAS plug-ins to function.<br />
There are several tools available for installing and upgrading VIB packages. They include the esxcli commands<br />
and <strong>vSphere</strong> Update Manager. For more information, see the <strong>vSphere</strong> Upgrade and Installing and Administering<br />
<strong>VMware</strong> <strong>vSphere</strong> Update Manager documentation.<br />
Install NAS Plug-In<br />
Install vendor-distributed hardware acceleration NAS plug-ins on your host.<br />
This topic provides an example for a VIB package installation using the esxcli command. For more details,<br />
see the <strong>vSphere</strong> Upgrade documentation.<br />
In the procedure, --server=server_name specifies the target server. The specified target server prompts you<br />
for a user name and password. Other connection options, such as a configuration file or session file, are<br />
supported. For a list of connection options, see Getting Started with <strong>vSphere</strong> Command-Line Interfaces.<br />
Prerequisites<br />
Install vCLI or deploy the <strong>vSphere</strong> Management Assistant (vMA) virtual machine. See Getting Started with<br />
<strong>vSphere</strong> Command-Line Interfaces. For troubleshooting , run esxcli commands in the <strong>ESXi</strong> Shell.<br />
Procedure<br />
1 Place your host into the maintenance mode.<br />
2 Set the host acceptance level:<br />
esxcli --server=server_name software acceptance set --level=value<br />
The command controls which VIB package is allowed on the host. The value can be one of the following:<br />
n <strong>VMware</strong>Certified<br />
n <strong>VMware</strong>Accepted<br />
n PartnerSupported<br />
n CommunitySupported<br />
3 Install the VIB package:<br />
esxcli --server=server_name software vib install -v|--viburl=URL<br />
The URL specifies the URL to the VIB package to install. http:, https:, ftp:, and file: are supported.<br />
4 Verify that the plug-in is installed:<br />
esxcli --server=server_name software vib list<br />
5 Reboot your host for the installation to take effect.<br />
