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

What’s new in XenServer 5What’s new in XenServer 5


XenServer 5 – Highlights

Enhanced Guest Support


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)

Core Xen Virtualization Technology

Core Xen Virtualization Technology


Xen: Engine of Innovation

• Open standard

• Work closely with OS vendors

• Advisory board: Citrix, IBM, Intel, HP, Novell, Red Hat and Sun Microsystems

• Leverage open source community


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

XenServer has the features today enterprise customers ask for• Advanced storage support, Live migration, High Availability/FT,

Workload Management, Provisioning

• Supports mixed Windows, Linux environments

XenServer is, and will remain, a first-class citizen within the Microsoft ecosystem• Interoperable by design with Hyper-V VMs and vice versa

• VHD filesystem support, including boot from VHD

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


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 Continuity With XenMotionHigh Availability: Planned downtime

Remote VM Guest Storage


Business Continuity High Availability: Planned downtime



Business Continuity High Availability: Unplanned downtime



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

VM

VMVM

VM


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
