The NetApp NFS Plug-in for VMware VAAI is not shipped with Virtual Storage Console for VMware vSphere; however, you can get the plug-in installation package and instructions for installing it from the NetApp Support Site at mysupport.netapp.com. You can then go to use the Virtual Storage Console page to complete your installation.
The plug-in is a software library that integrates the VMware Virtual Disk Libraries that are installed on the ESXi host. It is a good practice to install the plug-in because VAAI (VMware vStorage APIs for Array Integration) features such as copy offload and space reservations can improve the performance of cloning operations.
The plug-in is supported on systems running ESXi 5.0 or later with vSphere 5.0 or later and clustered Data ONTAP 8.1 or later or Data ONTAP 8.1.1 or later operating in 7-Mode.
To download the plug-in, go to the Software Download page on the NetApp Support Site and log in. In the row "NetApp NFS Plug-in for VAAI," select ESXi and click Go!. Continue through the pages until you reach NetApp NFS Plug-in for VMware VAAI Download. This page provides links to both the installation package and the installation guide.
Follow the VSC installation instructions in Installing the NetApp NFS 1.0.20 Plug-in for VMware VAAI.
After you install the plug-in, you must reboot the host. VSC then automatically detects the plug-in and uses it. You do not need to perform additional tasks to enable it.
