VMware Site Recovery Manager
Site Recovery Manager leverages VMware
Infrastructure to deliver advanced disaster
recovery management and automation

• Simplifies and automates disaster recovery
  workflows
• Setup, testing, failover
• Turns manual recovery run books into automated
  recovery plans
• Provides central management of recovery plans
  from VirtualCenter
• Works with VMware Infrastructure to make disaster
  recovery rapid, reliable, manageable, affordable

Site Recovery Manager Use Cases

• Target scenarios
• Restart of tens or hundreds of VMs in another
  datacenter
• Restart can be unplanned (disaster) or planned
  (migration)
• Can tolerate RTO of minutes to hours
• Requirements
• Second site running VirtualCenter and ESX
• Replicated Fibre Channel or iSCSI LUNs from
  supported storage vendors
• SRM is not
• A replication product
• Geo-clustering for applications in VMs

Disaster Recovery Setup

• Integrate with replication
• Identify which virtual machines are protected by
  replication configuration
• Map recovery resources
• Network resources, server resources, management
  objects
• Create recovery plans
• For virtual machines, applications, business
  units
• Convert manual runbook to pre-programmed response
• Customizable with scripting and callouts

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 torecovery hosts
• Execute recovery process
• Use pre-programmed plan
• Provide visibility into progress
• Manage networking
• Put VMs on right VLAN
• Change IP addresses

16
Testing

• Replication Management
• Snapshot replicated LUNsbefore test
• Delete snapshots of replicated LUNs after test
• Network Management
• Change all virtual machinesto a test port group
  before powering them on
• Customization/extensibility
• Same breakpoints and calloutsas failover
  sequence
• Extra breakpoints and callouts around the test
  bubble

18
Failback

• Setup DR protection from DR site back to primary
  site
• Failover makes VMs reside at the DR site
• Provide the failed-over VMs with protection
• Same setup as was done for initial protection
• Work with storage to reverse replication
• Test failback
• Test repeatedly same mechanism as with test
  failover
• Only set the failback date after the plan is
  perfect
• Failback to primary site
• Just hit the failover buttonfailback is failover
  in the reverse direction

SRM Failover Overview

• Shutdown protected VMs in Site A
• If online, orchestrates the controlled shutdown
  of protected VMs
• If offline, no action taken against protected VMs
  in Site A
• Promote the storage in Site B
• Replicated datastores are promoted to be
  Read/Write enabled
• Suspend non-critical VMs in Site B
• VMs identified to be non-critical are shutdown
  during failover
• Protected VMs from Site A powered up in Site B
• High priority VMs start up first
• Followed by Normal and Low Priority VMs

• Protected Site
• Pairing of Site A with Site B
• Array Manager Configuration
• Inventory Preferences
• Protection Group Setup
• Recovery Site
• Recovery Plan Setup
• Test your Recovery Plan
• SRM allows you to test your recovery plans
  without impacting production services

Practice makes perfect so test and test again

Bringing Automation to the Datacenter

• Facilities cooperation between VI farms at
  multiple sites managed by different people
• Fundamentally SRM is a VM migration tool
• Planed migrations for datacenter moves or
  consolidation
• Unplanned migrations in case of disaster
• Strategic relationships with service providers
  show the beginnings of the DR to the cloud
  movement

Summary
VMware Infrastructure is the safest place to run
applications

• Site Recovery Manager brings DR to your server
  and desktop workloadstoday!
• VMwares partnerships with storage ecosystem help
  you leverage your existing storage investments
  and get even more value from them
• VMware brings simplified and reliable DR to the
  most demanding enterprise applications as shown
  here with SAP
• VMwares vision will continue to drive up
  availability anddrive down cost
