Nevada Test Site conducted 928 atmospheric and underground test and now leads projects in Stockpile Stewardship, Defense and Homeland Security, and Environmental Management. Approximately 3000 people in locations across the US are directly employed by NSTec. Formed in 2005 as a joint venture between Northrop Grumman Corporation, AECOM, CH2M Hill, and Nuclear Fuel Services

Page 5 NSTec –Impact of Server virtualization OFFICIAL USE ONLY Vision Service Partnership Server Hardware 2000 - Moved to Rack mount servers 2002 - Deployment of HP DL380 series servers 2005 – Deployment of Virtual Servers on Dell 6850 Hardware 2007 – Transition to ESX server on HP c7000 blade series. Virtualization first had an impact by moving us toward large ESX servers to support as we deployed the largest Intel based machines in the enterprise. In 2007 per socket licensing, quad core processors, and blade servers ability to provide core infrastructure resulted in another move.

Page 6 NSTec –Impact of Server virtualization OFFICIAL USE ONLY Vision Service Partnership Networking/SAN Infrastructure 2005 FCIP module added to the MDS 9509 SAN switch to support iSCSI to the SAN to eliminate direct attached storage. 2007 deployment of a Cisco 6513 switch supporting 384 server drops. (Currently at 37% utilization) 2008 plans called for the deployment of a redundant 6513 switch to support redundant connections to each server. Additional 2008 plans called for an addition 2 Blades being added to the Cisco MDS 9509 SAN switch to a push to eliminate DAS storage. The move to a Blade enclosure equipped with 4 Cisco 3020 LAN switches and 2 Cisco 9214 SAN switches and virtualization complete changed the requirements we had been planning for.

Page 8 NSTec –Impact of Server virtualization OFFICIAL USE ONLY Vision Service Partnership Backup/DR/Coop VMware Consolidated Backup (VCB) is transitioning our backup process from agents on every server to a single agent on the ESX server. –VCB backups occur across the SAN. Virtual Machines portability allows DR site to have older hardware running ESX server to support a data center failure. Cloning and VLANs within ESX allow for easy duplication of environments for DR testing

9. Page 9 NSTec –Impact of Server virtualization OFFICIAL USE ONLY Vision Service Partnership Application Deployment/Upgrade Planning Application deployments have moved away from traditional upgrades of OS and Applications on existing hardware to more of a rip and replace. –Although rip and replace is normally not touted as a benefit the ability to setup a parallel server in just minutes create a benefit be allowing the application to be fully installed, configured, and tested before data is transferred over and it becomes production. Snapshots allow for quick recovery of servers after patching or upgrades. Monitoring the impact of increase cpu or memory resources on an application can be easily tested with a simple configuration change

10. Page 10 NSTec –Impact of Server virtualization OFFICIAL USE ONLY Vision Service Partnership Power/Cooling/Space In 2004 NSTec started working with Facilities to plan an upgrade to the power and cooling infrastructure of the data center as the current usage trend was going to exceed capability around 2007. In 2005 the move to virtualization prevented us from having to move forward with these plans and in 2008 we are still reducing the overall datacenter power consumption. Although space it not an issue in our primary data center virtualization, in conjunction with Blade and rack mounted servers, has reduced the overall server footprint from 416 square feet to 240 sq. ft. By the end of FY09 we plan to reduce the overall footprint 81% to 80 sq. ft Reduced operational cost by reducing the demand for racks, PDU, and KVM. Power & Cooling Savings per Year: 1,284,800 kWh in primary data center and 1,468,760 KWh enterprise wide ($146,876) Reduction of 2,276,592 pounds of CO2
