Introduction to Server Virtualization

Operating System

Enterprise App

Operating System

Virtualization Hypervisor

Running multiple Virtual Server instances on a physical server infrastructure by decoupling the Operating

System Software from hardware.

What is Server Virtualization?

Slide 4

Run multiple operating systems on a single server

Create shared pools of server resources to optimize your infrastructure

What is Server Virtualization?

Virtualization Main Benefits

• CAPEX and OPEX savings: • Improved server utilization

• Reduce hardware requirements by a 10:1 ratio or better

• Green IT

• Improved Manageability• Accelerate service provisioning time by 50-70% • Manage virtual machines from a central location

Slide 5

Slide 6

Gartner, October 26 2009

• 16% of workloads run on virtual environment today

•Prediction: 50% of workloads will be running on 58 million

virtual machines by 2012

IDC , October 26 2009

•16.5% of all new servers shipped in Q2’09 were virtualized• An increase from 14.5% in second quarter of 2008

Static Data Center Virtual Data Center

Traditional ADC vs. the future

• Changes are

infrequent

• Limited inter-team

communications

• Changes require

manual

intervention

• Dynamic

• Frequent updates

•Includes all tiers:

network, storage,

applications,

servers

Slide 17

“The ability to deploy capacity and server images virtually increases

speed of deployment by a factor of approximately 30”  Thomas Bittman, Gartner

“A new server can be up and running in three minutes - it used to

take Eli Lilly seven and a half weeks to deploy a server internally” Dave Powers, at Eli Lilly and Company

• The virtual data center is much more dynamic compared to its

physical counterpart

• Any configuration changes in the virtualization layer should also

be reflected in the ADC• Otherwise, the virtual application availability and performance

might be degraded

• The challenge of keeping the static ADC aligned with

application resources is becoming much more complex

The Network Admin Challenge

Slide 18

The ADC Must be Aligned with the Virtual Environment

• Time consuming• Prone to human

errors• Increased risk

• Time consuming• Prone to human

errors• inter-team

dependency • Increased risk

Slide 19

Can Scripting Help?

• Prone to errors• Time consuming• Management,

visibility and auditing

• Who writes and maintains the scripts?

• Does the script guarantee the sync?

Slide 20

• Inter-domain scripts

Introducing vAdapter

Slide 21

vAdapter is a virtual appliance for VMware virtual

Infrastructure

Automatic adaptation of ADC configuration to the

relevant virtual infrastructure changes

Tight integration with AppDirector and Alteon

Applications Discovery

• Automatically discover the ADC and VMware topology • Create mapping rules based on the discovered information

Data Center Trends

• More than half of companies are well down the infrastructure consolidation path Gartner 11/2006 IT Infrastructure customer survey

• Customers … are seeking more advanced capabilities and tools for their virtual environments IDC 2006 customer survey

• Virtualization is a major enabler for infrastructure automation, and will help accelerate the trend toward IT operations process automation Gartner Bittman 2007

• Automation is expected to play a strong role in managing virtualization resources in the next 18 months Server Virtualization Maturity Index, IDC Jan 2007

• Second phase of virtualization concentrates on the flexible allocation of resources to respond to business demand Gartner Bittman
