Isilon Integration with VAAI-NAS and VASA

It’s come up on my VAAI v2 (NFS) write-up that today there are only two products that offer vSphere Storage API for Array Integration for NAS (VAAI-NAS) integration with vSphere 5.  We all know that more will be coming, and we all hope it’ll be sooner, rather than later.  Personally, I predict that Isilon will be the next storage array with full VAAI-NAS support in VMware’s Compatibility Guides.

How can I be so confident?  I’ve seen it in action, and next week you can, too.

What Will VAAI v2 Do for You? Part 2 of 2: NFS

This post is the second of two describing the features of the VMware vSphere Storage APIs for Array Integration (VAAI) version 2 as it works with vSphere 5.  If you missed the first part, you can read it here: What Will VAAI v2 Do for You? Part 1 of 2: Block

Part 1 Review

My earlier posting covered the five features for block storage available in VAAI v2:

  • Hardware-Assisted Copy
  • Hardware-Assisted Zero
  • Hardware-Assisted Locking
  • Thin Provisioning Stun
  • Thin Provisioning Block Reclamation

 VAAI v2 for NFS Storage

Probably the biggest and most-anticipated aspect of VAAI v2 was the the addition of advanced features for NFS datastores.  VAAI v2 includes three features for NFS:

  • NFS File Cloning
  • NFS Extended Stats
  • NFS Reserve Space

I’ll cover each of them in detail below.

What Will VAAI v2 Do for You? Part 1 of 2: Block

Recently, someone pointed out to me that it was high time for me to write a follow-up to my “What Will VAAI Do for You?” posting.  Written shortly after the launch of VMware vSphere 4.1, it is my most-read post on the Everything VMware at EMC Community.

Since I wrote it, though, VMware has released vSphere 5, which (among a slew of other great features) includes version 2 of VAAI, now called the vSphere Storage API for Array Integration.  (You’re not mistaken: they’ve added a word to the name but kept the acronym the same — the acronym has achieved wide-spread common usage and changing it would only cause confusion.)

VAAI allows ESXi servers that use VAAI-enabled storage to work more effectively with storage.  In most cases this means offloading storage-related tasks from the server to the array, but there’s more to it than just that, as I’ll explain in this posting. Continue reading
