I can't get a grip of where I can find the NFS-plugin needed to get NFS acceleration in vSphere 5.
It doesn't seem to be a part of the Virtual Storage Console 2.1.1.
I see OnCommand™ Host Package 1.1 with Vmware support, but it seems to be overlapping VSC, and I can't get a grip if this is what I need.
Is it part of a product I need? Is it free?
As we are running Vmware with NFS on our production envirovment I would like to enable the plugin on a ESXi in the envirovment (pre-production) but outside the production cluster(or one ESXi at a time). Is it possible to phase in the plugin or is it systemwide within the same vCenter when I install it?
Are you refering to the VAAI optimization for NFS? If so, today it is available only with ONTAP 8.1 c-mode. Is that what you have loaded on your controllers? The VAAI for NFS will be available for 7-mode in a future release of ONTAP (soon!)
When released with 7-mode it will be a free download.
