VAAI Support for NFS: How?
On Chad's posts says:
What’s in this VNX update? A LOT (this is a shortened list with key ones from my perspective):
VAAI Support for NFS: This feature allows VAAI for NFS. It’s delivered via a VMware ESX server vStorage plug-in that creates and manages virtual disks as a set of files on a NAS device. The use cases include virtual disk cloning, VM instant provisioning, NAS hardware assisted VM snapshots and storage vmotion.
Any document that explains how to configure VAAI for NFS?
Thanks.

@kendcollins Is there any official statement when this will happen? It is really annoying to tell the customer that there is something in progress... over weeks!

The VSI plug-ins are not related to VAAI support or the vStorage Plug-in.
Here's the difference:
VSI plugs into vSphere client to interact with vCenter for out-of-band (outside of the data path) management.
vStorage plug-in installs into the ESX server and issues in-band (within the data path) commands to detect/etc VAAI support on the array.
Xanlith - please send me any/all details including what you are trying to accomplish. I cannot tell if you are having an issue trying to execute a VSI feature/function vs getting VAAI working??? or something else??

All,
Working on getting official word for you.....understood on the frustration part, hopefully we get this resolved very quickly.

Not sure this will help but, it is a start.
If an unsupported operation is attempted, the array returns an error to ESX and the ESX server will use its native method to perform the operation. VNX OE for File v7.0.35.X and Block R31.5.5xx supports VAAI with FC, iSCSI, and NFS protocols.
Please note that the ESX server must also support these features.
One can verify that VAAI functionality is enabled on the ESX server using vSphere. Navigating to the ESX server, Configuration tab, and choosing the Advanced Settings under Software brings up the Advanced Settings window. The HardwareAcceleratedparameters found in the DataMoversection and the HardwareAcceleratedparameter found in the VMFS3 section indicate whether VAAI is enabled on the ESX server. If the parameter is set to "1," the VAAI feature is enabled. If the parameter is set to "0," the VAAI feature is disabled. The features are enabled by default.
The esxcfg-advcfg command can also be used to set and get the HardwareAccelerated parameters.
The –s option is used to set the parameter, and the –g option is used to get the current setting.

Hi Nick,
Thanks for jumping into the fray. I've also escalated my SR on this and my account representative has gotten me in touch with her vSpecialist as well.
Unfortunately the ESXi servers and the VNX both are at the code level necessary to enable VAAI and the feature parameters are set to 1 but regardless Hardware Acceleration remains at "Not Supported". I've seen a few articles that suggest VMFS5 is at fault and that if you build your stores with VMFS3 and then upgrade to VMFS5 they remain supported but I dont have the environment necessary to test that since my stores are all in production already.

Adding a section from the VMware KB artice for future use.
vStorage APIs for Array Integration FAQ
Are there any caveats that I should be aware of in ESX/ESXi 4.x?
There are a few reasons why a hardware-accelerated operation may fail.
For any primitive that the array does not implement, the array returns an error, which triggers the ESX data mover to attempt the operation using software data movement. In the case of ATS, it reverts to using SCSI Reservations.
VAAI hardware offload cannot be used when:

Recent update: several issues have been resolved and eLabs is working on completing the round of certificaiton tests. Then the results will be submitted to VMware for their blessings.
I would say this should happen very soon, but we are now on the threshold of the holidays.....
More info as it becomes available.....

So it looks like Ken is right, the plugin is still in "beta" according to my account vSpecialist with no ETA on release. I probably wouldnt have put all the stuff in the FLARE/DART code release fanfare about NFS VAAI if the entire system isnt ready to go.

All,
Latest word is that the vStorage plug-in for "VAAI for NFS" has passed EMC/eLabs testing and has now been submitted to VMware for verification of test results and final certification action.

We can't do this in FLARE/DART because it needs changes on VMware's end as well.
The enabler is now posted and available.
