15 Disaster Recovery Setup Create recovery plans 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 preprogrammed response Customizable with scripting and callouts

16 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

17 Protected and Recovery Site Datacenters SRM PROTECTED SITE SRM RECOVERY SITE

18 Protected Site VMware Topology Map

19 User Interface SRM UI Access Local and Paired Site Protection Setup Recovery Setup

20 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

21 Setup Workflow Protection Site At the protection site the following setup activities are completed: The user pairs the SRM servers at the protected and recovery sites Security certificates are established between the SRM servers and the VC servers

22 Setup Workflow Protection Site - continued Array Managers Configuration Select the correct Manager Type from the Manager type drop down box Storage Partner Participation VMware provides the SRA specification Storage Partners create the SRA Storage Partners test the SRA VMware review the SRA test results SRA support with SRM granted if all test are passed Storage Partners

23 Setup Workflow Protection Site (continued) SRM identifies available arrays in the Protection and Recovery Side and the replicated datastores and determines the datastore groups Protection Side Array Discovery Recovery Side Array Discovery Replicated Datastores and Datastore Groups

24 Setup Workflow Protection Site - continued Using the Inventory Preferences Mapper, the user maps resources in the protected site to their counterparts in the recovery site.

25 Setup Workflow Protection Site - continued A protection group is a group of VMs that will be failed over together to the recovery site Working through the Protection Group wizard you will need to select a temporary location for placeholder VM configuration files for the protected VMs at the recovery site.

26 Setup Workflow Protection Site - continued Working through the Protection Group wizard a user selects which VMs need to be protected and assigns them to a protection group The creation of a protection group results in VC inventory updates in the recovery site

27 Setup Workflow Recovery Site At the recovery site the following setup activity is completed: The user creates a recovery plan which is associated to a single or multiple protection groups

28 Recovery Plan VM Shutdown High Priority VM Shutdown Prepare Storage High Priority VM Recovery Normal Priority VM Recovery

29 Recovery Plan - continued Low Priority VM Recovery Post Test Cleanup Storage Reset SRM Recovery Plan Benefits: turn manual BC/DR run books into an automated process specify the steps of the recovery process in VirtualCenter Provide a way to test your BC/DR plan in an isolated environment at the recovery site without impacting the protected VMs in the protected site

30 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

31 Testing a Recovery Plan SRM enables you to Test a recovery plan by simulating a failover with zero downtime to the protected VMs in the protected site Storage configuration during a SRM Test failover from Site A to Site B for datastore shared-san-2 Site A - Protected Site Site B - Recovery Site Data Replication continues between the Source LUN and Target LUN The data synchronization between the Target LUN and the Clone LUN is suspended Read Write Enabled Write Disabled (read only) Read Write Enabled Source LUN (shared-san-2) Protected VMs (app_vm7 to app_vm12) Protected VMs that will be recovered to Site B Target LUN (shared-san-2) Clone LUN (shared-san-2) Protected VMs (app_vm7 to app_vm12) Protected VMs powered on in Site B during the SRM Test failover Note: Datastore shared-san-1 will be in the same configuration state as shared-san-2

32 Testing a Recovery Plan - continued Status Recovery Only Success Errors Success Waiting for Input Test Only

33 Recovery Plan Reports Accessible compliance Exportable recovery plan Exportable recovery results Maintained history

34 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

35 Executing an Actual Failover WARNING - Executing an actual failover with SRM will permanently alter virtual machines and infrastructure of both the protected and recovery sites Storage configuration after running a Recovery in SRM (Actual Failover) from Site A to Site B Site A - Protected Site Site B - Recovery Site Data Replication is suspended Write Disabled (read only) Read Write Enabled Protected VMs (app_vm7 to app_vm12) All powered off by SRM At start of SRM Recovery Source LUN (shared-san-2) Target LUN (shared-san-2) Protected VMs (app_vm7 to app_vm12) All powered on by SRM during the SRM Recovery Note: A Clone LUN is not used during an actual failover in SRM.

36 Executing an Actual Failover - continued WARNING - Executing an actual failover with SRM will permanently alter virtual machines and infrastructure of both the protected and recovery sites WARNING - Failback to the protected site is a not an automated process in SRM 1.0

37 Datastore Re-signature During Failover SRM will automatically perform a re-signature on the Datastores in the Recovery Site that were replicated from the SRM Protected Site LVM.EnableResignature=1 With a re-signature - Datastore names will change to snapxxxx_datastorename, for example snap shared-san-1 snap shared-san-2 WARNING - The re-signature of the target datastore has implications during a failback (resync) of data back to the SRM Protected Site

38 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
