Economical Disaster Recovery through

Virtualization

Mario MarquezSenior Systems Engineer – Canada

The number 1 reason SMB’s virtualize is for disaster recovery

Before Virtualization…

• Before virtualization only large companies with large IT budgets could afford “hot-site” disaster recovery (DR)

• DR capabilities required duplicate hardware and infrastructure and very complex failover processes

• As hardware and software at the source site were modified those changes had to be made at the DR site as well

• Hot-site disaster recovery effectively consisted of having 2 datacenters to manage

• Testing of backups almost impossible for the SMB

After Virtualization…

• Disaster recovery now available to even the smallest businesses

• Now complete failover capabilities can be obtained for any business far less cost than was previously available in the industry

• Virtual machines are portable and as such can easily be copied to alternate sites, DR facilities or co-located servers for quick resumption of business in the event of a failure or catastrophe

• Testing backups becomes as simple as the click of a button

The Cost of Downtime

What would a major disruption cost your company per hour?

Key Takeaways

•All organizations lose at least $50K / hour due to downtime

•>50% or organizations risk losing >$250K/hour

Disaster Recovery & Business Continuity

Provide DR & BC with less risk and time than backup

solutions

Short replication windows and

network bandwidth constraints

Migrate VMs to distant data

centers & ensure performance

Problem Space

Provide replication without significant CapEx & OpEx

How vReplicator Works

1• Initial Pass – without ABM or CBT enabled • Replication engine removes whitespace • Applies to ESX 3.5 and ESX 4.0 hosts

2• Initial pass – with ABM enabled • Active Block Mapping (ABM) replicates only active blocks. • Blocks occupied by deleted data not replicated.
