Windows Server 2012 ODX support with EqualLogic Storage
Here is a good paper written by Chuck Farah and Rajkumar MR titled “Understanding Microsoft Offloaded Data Transfer on Dell EqualLogic PS Series Arrays”.
Abstract: This White Paper provides basic understanding of the bulk data transfer functionality of Offloaded Data Transfer, ODX with Microsoft Windows Server 2012 providing improved compute utilization on DellTM EqualLogicTM PS Series SANs.
One of the things I have been doing recently in my lab is creating Hyper-V SQL Server VMs from a 20GB Hyper-V template which lives on a file share called Z:\VMgoldcopy directory (on EQL storage). The template is syspreped so all I have to do is copy the template from Z: to my shared E:\VMStorage (on same EQL Storage as Z:\) , rename it, then use Hyper-V Manager to create a new VM using this copied / renamed VHDX as the virtual hard disk. The copy process is smoking fast, hitting 300+MB/s thanks to ODX. This paper provides details behind this goodness and gives you an idea of the benefits it can provide to you and our customers using EQL with Windows.
