XenServer: Design for a better utilization
Fact 1: Virtualization requires resources
Fact 2: Scalability of a server will be reduced by virtualization
By choosing the wrong virtualization solution, scalability gets unnecessarily worse
→ wrong virtualization solution = more hardware required

Underlying technology
Old: Emulation New: Paravirtualization
• Runtime binary translation
• Device emulation
• Heavyweight hypervisor (includes drivers)
• Designed for hardware assist
• Fast, enlightened I/O
• Lightweight hypervisor (native drivers)

Why virtualize XenApp?
• Reduce hardwarefootprint in the datacenter
• Accelerate 32- to 64-bitserver transition
• Provide alternative tox64 migration
• Reduce application downtime
• Add high availability and fault tolerance
• Simplify disaster recovery
• Simplify server provisioning
• Manage single image for physical and virtual servers
• Address test and developmentscenarios
Enhance availabilityEnhance availability
Consolidate Simplify management

• Issue: 32-bit Windows can only address 4 GB RAM
• Underutilizes modern multi-core processors
Reducing XenApp Server Count
4 GB RAM exhausted
Plenty of processor (dual socket, quad-core processors) cycles still available
