Offloaded Data Transfers (ODX) support in Hyper-V

You will start to see some announcements around these features and support very shortly.  These technologies are important to customers, and we wll be making sure to support our customers :-)

There was a press release about this last month: http://www.emc.com/about/news/press/2012/20120611-01.htm

Look at the "EMC Announces Broad Support For Windows Server 2012" section.

In short, we will be support ODX in upcoming releases of FLARE for VNX and Enginuity for VMAX.  Other products may also implement support, but we most commonly get asked about VNX and VMAX.

Incidentally, Microsoft demonstrated ODX functionality at Microsoft TechEd using VNX H/W.  Refer to the following link for more details and a video cut of the demo: http://emcmsft.typepad.com/sammarraccini/2012/06/inside-the-partnership-emcmsft-the-video-series-episode-31-microsoft-teched-2012-keynote-odx-and-in-.html

I am confused between ODX and deduplication. Can deduplication save both capacity and time (to copy)?

That’s a very loaded question. ODX is not deduplication – it’s an offloading technology so that if the source and destination are on the same array, a copy operation does not have to traverse the path to the hosts involved.

As for deduplication, it can save capacity, and in certain cases time to copy. It depends on where the deduplication happens, and when. I suggest taking a look at this for a primer on it.

EMC has deduplication techniques that run the gamut, so if you’re considering a particular type of deduplication, you’ll probably have to name the product (Avamar deduplication, vs Data Domain deduplication vs VNX deduplication).
