Virtual Server Recovery (VSR)

Business Drivers Clients need faster recovery and increased server recovery reliability

Challenges of recovery on physical infrastructure:

Need for faster recovery and increase reliability of recovery in the event of an IT disruption High cost as associated with maintaining redundant in-house servers Risk of failure to recovery on unlike hardware High cost and complexity associated with need for travel to physical infrastructure at time of disaster

IT Drivers There are many challenges associated with disaster recovery on a physical infrastructure

Identical hardware required for recovery

• Costs are doubled, complexity is increased
• Accurate configuration information is critical

Idle hardware

• Standby hardware is needed for faster recovery time objective
• Servers that need repurposing at time of disaster are labor intensive and time

consuming Slow, complex recovery process

• Different solutions for different availability tiers
• Separate procedures for system and data disks
• Separate procedures for desktop PCs
• Multi-step recovery process

VSR Cloud Recovery …and overcomes the challenge of Recovery Variability

If one of your critical servers goes down:

• In the very best case, how long will it take to restore an equivalent server?
• In the very worst case, how long will it be?
• Where in between in the most likely case?

Best case Worst case Likely case: 48 hrs +/- 10 hrs 48 20 80 40 60 Best case Worst case Likely case: 3k mins +/- 600 mins 3k 1k 5k 2k 4k Hours Minutes

VSR Storage IBM Cloud VSR Portal

• Dramatically improved RTO and RPO
• Extremely reliable protection from server interruptions to full DR for physical and/or virtual servers
• Immediate deployment: avoid CAPEX, design, planning, installation
• Easy to use
• Hypervisor agnostic
• Access to recovery infrastructure remotely, so client need not travel to recovery centre
• Client avoids the hassles of recovery on non-like hardware
• Client may more easily and frequently test the failover and recovery
• Our ‘cross-server consistency’ feature ensures client applications run seamlessly when their servers failover to our cloud recovery

infrastructure

• Our Always Available Virtual Machine service element can be archive, test and production overflow, besides recovery

VSR value proposition …in a nutshell

Business challenge

• Customer received tape based IT DR services
• Challenge to provide significantly improved recovery time and recovery point

Solution

• IBM performed a Business Impact Analysis to understand resilience
• Deployed Virtualised Server Recovery (VSR) as a managed service to support business critical

services and core applications Benefits

• Core application Recovery Time Objective (RTO) reduced, giving the ability to restart all

applications quicker

• Managed service means a reduced involvement of Customer staff
• Testing facilities improved
