Operating Expense OutstrippingNew Investments
Most organizations will spend $0.50 for power and cooling for every $1 in servers•$29B to be spent on power and cooling
Source: John Humphries, IDC (2007)
$8 spent in maintenance for $1 spent in new infrastructure
Cost of housing servers is approximately:
• $1,000 per sq. ft. or
• $2,400 per server or
• $40,000 per rack

Why Virtualize?
• Server or data center consolidation• Average physical servers utilized only <15%
• More efficient use of physical assets
• Promotes greater centralization and security
• Reduced capital and operating costs
• “Green Computing” – less power / cooling
• Flexibility - Allow IT agility• Dynamically respond to business needs
• Virtual workloads are mobile and easy to create and manage
• Business Continuity• Improve application availability
• Key part of disaster recovery strategy

XenConvert – P2V Conversions
• What is it?• Feature of XenServer 5
• Stand-alone Wizard Interface
• Enables the conversion of a physical server or desktop workload into a virtual machine (VM)
• What formats does it support?• Conversion to a XenServer ready
VM (XVA) or to a Microsoft Virtual Hard Drive VM (VHD)

Power of
• Paravirtualization is key to performance• Allows the kernel and I/O paths to know it’s being virtualized
• Cooperation provides best performance
• Utilizes hardware-assisted virtualization• Fully supports Intel VT and AMD-V enabled processors
• Hardware-assist allows high performance without emulation
• Community Support

Provisioning Server & XenServer
Provisioning Server(streaming service)
• Workloads can be provisioned to a VM the same as to physical servers
Virtual to Physical
• Servers can be moved from physical to virtual and back according to load• New workloads or more capacity can be quickly provisioned

Business ContinuityHigh Availability with XenServer 5.0
• Planned Downtime (e.g. Physical server maintenance)• Migrate live VM and application workload using XenMotion
• Perform maintenance on physical server
• Migrate VM back to original server
• No downtime!
• Unplanned Downtime (e.g. Physical Server Failure)• Receive alert warning of failure via email
• Auto or manual restart of VM
• Downtime limited to time it takes to restart VM
• NOBODY can live migrate a dead server!
• Zero Downtime using Fault Tolerance • Duplicate physical server and adding fault tolerant software from Marathon
Technologies for fail-over.
• No downtime in the event of unplanned downtime to a physical server

Business ContinuityZero Downtime using Fault Tolerance • Fault tolerance - no application
outages
• Synchronous data protection -no data loss
• Supports all Windows apps – no customization required
Business Value
• Companies can confidently run production applications in virtual machines - gain consolidation benefits across much broader range of applications

XenServer Storage Repositories
Partner Storage Repositories• NetApp ONTAP API “LUN per VDI”• Open API and DDK
Storage Repositories Automate• Thin Provisioning• Snapshots• Cloning• Copy on Write
• XenServer directly manipulates SRs to deliver guest storage
• Ideally matched with “VM Aware” storage & direct array integration
