Bechtel
One of the world’s largest and most successful
global infrastructure construction firm chooses
XenEnterprise
400 servers in production
30% of physical servers are virtualized
Motivation for virtualization isincreasing server utilization and rapid provision and decommissioning of
servers.
Began looking into XenServer toachieve higher levels of performance
Replace all other virtualization productswith XenServer Enterprise Edition
before the end of 2007

KBC Clearing
Leading Belgium/Netherlands based Europeanfinancial services institution Leverages
virtualization for a critical data center relocation
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 werekey criteria in selecting XenServer.
“ 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

Windows Test and Dev
requirements for rapid provisioning of servers
Existing user of VMware Server
Initially purchased 4 XenServer
licenses currently running 12 VM’sacross 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.”
