  Advantages of Virtual Disaster Recovery


Virtual machines are portable
Virtual hardware can be automatically configured
Test and failover can be automated (minimizes human error)
The need for idle hardware is reduced
Costs are lowered, and the quality of service is raised

Disaster Recovery Pain Points

Lack of a reliable disaster recovery plan
  27-30% of business have no disaster recovery plan (VMworld, Imation)
Inability to meet RTO and RPO requirements with current plan
  Business needs and/or regulatory needs
  Need to improve RTO from days to minutes or hours
  Need to improve RPO from 24 hours to 1 hour or less
Expense related to hardware at remote site
  Idle hardware at recovery site (capital cost)
  Need to maintain system and application images at secondary site
  (operational cost)
  Unable to instantly repurpose machines at the secondary site
  (RTO impact)

                               For virtual machines, applications,
                               business units

                          Integrate with replication
                               Identify which virtual machines are
                               protected by replication configuration

                          Map recovery resources
                               Server resources, network
                               resources, management objects

                          Specify recovery process
                               Convert manual runbook to pre-
                               programmed response
                               Customizable with scripting and
                               callouts
     Setup: Mapping Recovery Resources
                                       Production   Disaster Recovery

Maps production resources to
resources available at recovery site
    Virtual machine hierarchy
    Resource pools
    Network connections


Eliminates complexity of managing
recovery site resources
Setup: Building Recovery Plans

                          Turn manual runbook into
                          automated process
                             Specify steps of recovery process
                             in VirtualCenter

                          Extensible framework
                             Scripts for specialized tasks
                             Checkpoints for manual steps
                             Enables integration with physical
                             recovery
Failover Automation

                      Detect site failures
                           Raise alert when heartbeat lost

                      Initiate failover
                           User confirmation of outage
                           Granular failover initiation

                      Manage replication failover
                           Break replication
                           Make replica visible to recovery hosts

                      Execute recovery process
                           Use pre-programmed plan
                           Provide visibility into progress
Testing

          Replication Management
               Snapshot replicated LUNs before test
               Delete snapshots of replicated LUNs after test

          Network Management
               Change all virtual machines to a test port group
               before powering them on

          Customization/extensibility
               Same breakpoints and callouts as failover
               sequence
               Extra breakpoints and callouts around the test
               bubble
Failback

           Promote secondary site to primary
                For one or more VMs

           Add VMs to DR profile
                Protect them at another site

           Manual failover
                Short downtime (minutes)
                Likely to be individual
                VMs/applications
