You're setting up your virtual servers on Hyper-V servers and you're moving stuff around pretty quickly... You place two busy virtual machines (VM's) on the same host. Performance is bad. You need to move the VM's without downtime - we use Windows 2008 R2 Live Migration to show this. By accident, you place multiple heavily utilized LUNs for different VM's that are competing with each other on the same set of disks. No problem. NQM gives you the ability to be able to place a threshold on LUN's (like 500 IOPS max for SQL 2008 R2 in the video) and let others (like a standalone Exchange 2010 VM in the video) have more IOPS to service more requests.
EMC storage devices can do this in both physical and virtual environments. CLARiiON Virtual Provisioning and Thin LUNs simplify SAN management and allow for dynamic online growth anytime in the future.
