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

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 Continuity with XenServer

Business Continuity with XenServer

18© 2008 Citrix Systems, Inc. — All rights reserved

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

Storage and XenServerStorage and XenServer

Storage – the Hard Part of Virtualization

Storage Infrastructure

• First generation virtualization treats storage as “dumb blocks” and implements all storage functions in the host

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
