23. XenServer with XenApp
• 3-4x more users per host
Consolidation • Up to 75% fewer servers
• No performance compromises
Increased • Fewer moving parts to manage
Agility • More flexibility and responsiveness
Higher •ZZero-downtime h t maintenance
d ti host i t
Availability • Auto-restart High Availability

25. Reducing XenApp Server Count
Solution: Virtualise the server with Citrix® XenServer™
3-4 times more users per (host) server
Before: 100 users After: 300+ users
16 GB RAM
Physical Server Two Quad-core processors
4 GB RAM 4 XenApp Virtual Machines
Two processors (4 GB RAM, 2 Virtual CPUs for each)

26. Provisioning Services with XenApp
