For the second year in a row, all of the MMS Labs were 100% virtualized using Windows Server 2008 R2 Hyper-V and managed via System Center by our partners at XB Velocity and using HP servers and storage. MMS 2010 was the first year all of the labs were provided via virtualization. In previous years, the MMS Labs were all delivered using physical servers. To say moving from physical to virtual was a huge success would be an understatement.
Here’re a few apposite stats comparing MMS 2009 to MMS 2010 last year:
Power reduction of 13.9x on the servers:
- MMS 2009: 570 servers * 200 watts per server = 114,000 watts
- MMS 2010: 41 servers * 200 watts per server = 8,200 watts
Power reduction of 6.3x on the clients:
- MMS 2009: Rich clients: 650 clients * 120 watts per client = 78,000 watts
- MMS 2010: Thin clients: 650 clients * 19 watts per client = 12,350 watts
Finally, “a total of 40,000 VMs were delivered over the course of MMS 2010 on 3 racks of servers. (Technically, it was 6 half racks, but since we used full racks this time, I’m calling it 3 racks so we’re making an apples to apples comparison…)”
Here’s a diagram of the rack with the front of the rack on the left and the back of the rack on the right. The blue lines are network cables and orange lines are fiber channel. Remember, last year we had 82 network cables; this year a total of 12 cables, 8 for Ethernet and 4 for Fiber Channel.
