Great post! I do have a specific one I haven't had clearly answered just yet, though I've read blogs by / been in contact with Bas. Here's the scenario:
On a NS-960 with an iSCSI LUN presented to an ESX host, does the VAAI offload the additional IOPS to the DataMover or the Storage Processor directly?
My confusion is that the type of I/O that is bound to be generated by the three features is inherently a block level task, but the terms are named
"DataMover/HardwareAcceleratedMove" and "DataMover/HardwareAcceleratedInit." Logically my mind leads me to think the load is on the SP / backend, but by naming convention I think the task is handled by the DMs. Can you clarify for me?
Thank you sir! That's the level of clarity I wanted to ensure before I provided a Technical Consultant with a definitive answer. I appreciate the reply.
Thanks for the comment. VAAI is integration on the native block side of the array at the storage processor level. I can see that it is a bit confusing due to VMware labeling the settings with DataMover. To clarify, in the EMC world Datamover refers to a NAS head that serves us iSCSI/NFS/CIFS volumes. Although VMware labels the option with DataMover, it is actually integration to the native block side of our array by way of the storage processors.
With that being said, VAAI will only work with on the native block side (Clariion) of our array by way of iSCSI/FC/FCoE. So to confirm yes the offload will happen at the storage processor level.
Any idea when VAAI will be available on the VPLEX? In the list of arrays it says Q3/2011 but I didn't think it was available yet in the latest GeoSynchrony code.
Hi! I'd also like to know when VPLEX will be supported with VAAI. Thanks.
Cihl, there is a plan, it is on the roadmap, customers can contact the VPLEX sales overlay team or Vplex champions to get an NDA presentation to communicate this to customers.

Hi Clint -

Thanks - Keep the knowledge coming!
