Bechtel
One of the worlds largest and most successful
global infrastructure construction firm chooses
XenEnterprise

• 400 servers in production
• 30 of physical servers are virtualized
• Motivation for virtualization is increasing
  server utilization and rapid provision and
  decommissioning of servers.
• Began looking into XenServer to achieve higher
  levels of performance
• Replace all other virtualization products with
  XenServer Enterprise Edition before the end of
  2007

KBC Clearing
Leading Belgium/Netherlands based European
financial services institution
Leverages virtualization for a critical data
center relocation
XenSource XenEnterprise outperforms VMware ESX.
When we did a performance test on both Linux and
Windows, XenSource came out best. Rob de Wit,
KBC Clearing

• Evaluated VMware and Citrix XenServer
• Goal was to consolidate servers and increase
  utilization
• 40 physical servers consolidated to 4 physical
  servers
• Performance, ease of use, affordability and
  industry support were key criteria in selecting
  XenServer.

Rollins Corp
Diversified company Expands virtualization with
XenEnterprise

• Windows Test and Dev requirements for rapid
  provisioning of servers
• Existing user of VMware Server
• Initially purchased 4 XenServer licenses
  currently running 12 VMs across his 4 dual
  opteron servers
• Added 21 more server licenses in April

Decision points for XenSource were price,
performance, IBM server proven status and upgrade
path for higher end product, XenEnterprise.
