What is Virtualization?

• Virtualization is the pooling and sharing of IT
  resources that includes servers, storage, and
  networking.

3
WHY VIRTUALIZE?

• COST BENEFITS
• REDUCE HARDWARE COSTS BY AS MUCH AS 50
• REDUCE TIME TO PROVISION NEW SERVERS UP TO 70
• REDUCE POWER CONSUMPTION - SAVINGS 500 - 600
  PER YEAR, PER SERVER
• MINIMIZE DOWNTIME ENSURING BUSINESS CONTINUITY

VMware Virtualization

• HA / DRS
• VMware HA allows virtual machines on failed ESX
  server hosts to restart on another
• ESX host. The DRS solution uses system
  algorithms and user created rules to determine
  optimal placement of virtual machines

VMware Virtualization (Contd.)

• VMotion
• Ability to migrate a running VM from one
  physical host to another without interruption
• Storage VMotion
• Ability to migrate storage from one location to
  another without server interruption
• VDI virtual desktop infrastructure

6
VMware Virtualization (Contd.)

• Site Recovery Manager
• Guides users through the process of creating,
  automating, and testing disaster recovery plans
  for their virtual infrastructure

7
Physical vs Virtual

• Started to Virtualize 4th quarter 2005
• 90 of all new servers are VMs
• 1000 VMs by 2009-2010

8
Accomplished

• Today DoITT has deployed over 500 Virtual
• Machines on HP DL 585s running VI3
• Implemented VMware 3.5 and Virtual Infrastructure
  2.5
• We are averaging 25 to 30 VMs per physical host

9
Accomplished (Contd.)

• Hosted applications
• - Web Applications
• (Includes agencies public facing websites)
• - SQL Database
• - Blackberry
• Lab Manager
• Developers tool for rapid deployment of test
  environment

10
Current

• Mission critical application deployment
• Citrix application delivery infrastructure
  testing phase
• Thin Clients
• (Pilot test deployment of 50 Thin Clients
  including the 311 Call Center)

DoITTs Next Steps

• Exchange
• Enterprise Vault
• Business Continuity

12
DoITTs Offerings

• Platespin / Power Recon
• - Deployed in agencies for 30 days
• - Create virtualization assessment with
• software that measures, analyses and
  determines the optimal fit between server
  resource supply and workload demand
