14 Deep Partnerships with Industry Leaders Hardware Partners Software Partners

15 Agenda Company and technology overview Disaster recovery problem Immediate opportunity Use of virtual infrastructure as failover target for physical servers Longer term Virtual infrastructure enables business continuity Real world results

16 Why Focus on Business Continuity In the past, backup & recovery was best effort Today the standards are different More reliability is expected Faster pace of business generates more critical change Intense competitive environment requires high service levels There is an increasing number of threats Terrorism Natural disaster Viruses and worms Hackers and industrial espionage Subcontractors going out of business Human error

17 Every year, one out of 500 data centers will experience a severe disaster* 43% of companies experiencing disasters never re-open, and 29% close within two years* 93% of business that lost their data center for 10 days went bankrupt within one year*** Business at Risk 81% of CEOs indicated their company plans would not be able to cope with a catastrophic event** Disaster Recovery is a focus of executive management *McGladrey and Pullen **INFOCON Magazine, October 2003 *** National Archives & Records Administration

18 Components of Disaster Recovery Strategy Ensure successful recovery Diligent use of a reliable backup tool Regular testing of recovery procedures Meet the TTR (Time To Recover) objectives Target recovery hardware available Alternate site available Processes documented and automated Put personnel plan in place Primary and backup DR coordinators designated and trained Dry runs are conducted regularly

19 Customer Choice for Recovery Physical to Physical Physical to Virtual Virtual to Virtual

20 Recovery Option 1: Physical to Physical Restore

21 Recovery: Physical to Physical Use backup software such as Veritas NetBackup or Legato NetWorker Back-up agent on each physical system under protection A backup server Tape array or ATA storage To recover Configure target recovery hardware Install Windows Configure permissions, accounts, registry, etc Install backup agent Run backup agent for single-step applications and data recovery from the backup copy

22 Agenda Company and technology overview Disaster recovery problem Immediate opportunity Use of virtual infrastructure as failover target for physical servers Longer term Virtual infrastructure enables business continuity Real world results

23 Challenges of Testing Recovery Hardware bottlenecks Need a separate target recovery server for each of the primary servers under test If not doing bare metal restore, need to locate target recovery hardware matching exactly the primary server configurations Lengthy process with manual interventions Configure hardware and partition drives Install Windows and adjust Registry entries Install backup agent Before recovering automatically with the backup server Personnel not trained Complex processes and limited equipment availability make it difficult to train personnel

24 Recovery Option 2: Physical to Virtual VM Templates with Operating Systems and Backup Agents are created and archived Full system restore occurs into VM using existing recover agents

25 Virtual Hardware for Real Recovery Follow the usual procedure for data backup For recovery: Find ONE physical server (with one or two CPU ) Install GSX Server or ESX Server* Copy from a template library a virtual machine with the appropriate Windows OS service packs and the Backup Agent pre-installed Register and start VM, edit IP addresses Restore from tape into VM using backup server

26 Physical to Physical Repeat for each box Find hardware Configure hardware / partition drives etc. Install Operating System Install backup agent Adjust Registry entries, permissions, accounts single-step automatic recovery from backup server Compare Recovery Steps Physical to Virtual Do Once Repeat for each box Find hardware Install VMware w. Templates single-step automatic recovery from backup server

27 Physical to Physical Repeat for each box Compare Recovery Steps: Bare Metal Find replica hardware Use specialized bare metal recovery tool to capture system image. Restore the system from baremetal image Recover newer data from incremental backup as needed Physical to Virtual Do Once Repeat for each box Find hardware Install VMware Use P2V Assistant to capture image of a production system & transform it into VM Recover newer data from incremental backup as needed

28 Why Virtual Infrastructure for DR? Hardware Independence Flexibility to restore to any hardware Hardware Consolidation / Pooling / Oversubscription Test recovery of all systems to one physical server Speed up recovery Use pre-configured templates with pre-installed OS & backup agent Single-step simplified capture and recovery Different purposes same procedures Staging, Deployment, Disaster Recovery One step system and application recovery No additional licensing requirements for bare metal restore tools More trained personnel available

29 Disaster Recovery TCO Model: Virtual Failover Hardware for Physical Primary Site In this model, we compare TCO of a physical and virtualized based disaster recovery for 15 mission critical servers Pre VMware Every year need to buy 5 Intel servers for the primary data center and 5 more exact same servers for the failover data center (3-years server lifecycle) With VMware Virtualize failover hardware in the backup data center on ESX Server using hardware de-commissioned from the primary data center Model Results Reduced TCO by 53% Reduced recovery time from 40 hours to 3 hours

30 Disaster Recovery Success Story The Challenge Find less hardware-intensive approach to business continuity service that guarantees data security and server stability while reducing costs and time to market By allowing operating environments to reside in software, as opposed to physical servers, VMware GSX Server enables us to recover many failed servers onto just one machine. Richard Pursey CEO NeverFail The VMware Solution VMware GSX Server eliminated need for one-to-one mirroring of servers, reducing hardware and maintenance costs by 70% Delivered world class disaster recovery solution combining real-time server continuity w/ rapid recovery on virtual machines Preserved full isolation and security of individual servers Consolidated up to 10 servers on more reliable and scalable hardware, providing headroom for future business growth Reduced hardware and maintenance costs

40 Simplified processes for recovery Restore system and application data in one step Single-step simplified capture and recovery One step system and application recovery No Windows registry issues Easy-to-automate recovery No need for 3 rd party bare metal restore tools Reduce learning and ramp-up Reduce software licensing expense Use the same methodology through application lifecycle Staging /Deployment/ DR Test once recover anything Application independent recovery => simplified testing

41 Disaster Recovery Success Story Being a financial institution, when our client hits our Web site, it needs to be up 24/7. We can do that by using network load balancing and VMware software. If the hardware goes down, I just move the virtual machine over to another system and bring it up. Scott Hill Sr. Technology Officer Oak Associates The Challenge Oak Associates, an independent equity investment manager for institutions and individuals, needed to meet availability and disaster recovery requirements driven by time sensitive financial transactions and billions of dollars under management The VMware Solution VMware GSX and ESX Servers enable Oak Associates to replicate their critical infrastructure to a secondary site 27 miles away for efficient and reliable disaster recovery Implemented cost-effective high-availability architecture not feasible without VMware Time to complete recovery is reduced from days to hours Can copy a server in three minutes Cut server hardware costs in half Saved more than $100,000
