VMware vcenter Site Recovery Manager 5 Technical

Top IT Goals for Virtualization Top 5 IT Objectives for Virtualization Source: VMware customer survey January 2010 Use virtualization to improve business continuity 46% Improve virtual machine performance 33% Increase the server consolidation ratio 32% Improve VM environment management 31% More mission-critical applications 24% Copyright 2009 VMware, Inc.

Virtualization Makes DR Easier, More Reliable Hardware Independence Reliably recover a virtual machine to any hardware Repurpose previous generation equipment to recovery site Encapsulation All information about a system is stored as flat files on disk Entire systems can be protected with data protection tools Partitioning and Consolidation Reduced hardware requirements at production and DR sites Can use higher consolidation ratios at DR site Resource Pooling Transparently share and allocate hardware resources Automatic resource optimization Automation is needed to lower risk, increase confidence

Non-Disruptive DR Testing Production Site Recovery Site Isolated test network at recovery site Suspended Test/Dev VMs Copy of Production Replication SRM provides non-disruptive testing of disaster recovery plans

Granular DR Testing and Failover Group VMs by application, service, business unit, etc. - create a recovery plan for each Recovery Plan 1 (CRM) Test or fail over only what is necessary i.e. Not all or nothing Recovery Plan 2 (Website) SRM enables granular testing of disaster recovery plans Recovery Plan 3 (Entire Site)

Recovery Plans Export recovery plan Suspend running workloads at recovery site to free up server resources for DR

Running a Recovery Plan Export recovery plan

Define VM Start Order and Dependencies Five priority groups, set VM dependencies in each group 17

Network Settings Customization Same IP settings at each site (e.g. Cisco OTV) Works great with SRM lowers complexity and recovery time Different IP settings at each site SRM automates IP change using GUI or command line tool

Automating DNS Updates Linux/UNIX command nsupdate Active Directory/DNS command dnscmd.exe Dynamic DNS DNS Update Scripts included with SRM C:\Program Files (x86)\vmware \scripts\callouts Appliance API E.g. Infoblox

Isolated Test Network Separate vswitch at recovery site

Protecting a VM with vsphere Replication Right-click on the VM 35

Protecting a VM with vsphere Replication Configure Recovery Point Objective (RPO) Asynchronous replication only, 15 minute 24 hour RPO 36

Protecting a VM with vsphere Replication Guest OS quiescing with MS VSS Select target location for VM 37

Protecting a VM with vsphere Replication Customize replication settings per virtual disk (.vmdk) 38

Protecting a VM with vsphere Replication Auto-assign or specify VR Server Multiple VR Servers can be deployed to scale the environment 39

vsphere Replication Details Asynchronous replication Does not use VMware snapshots Initial copy can be provided to recovery site Requires VM virtual hardware version 7 or higher Changes on source disk(s) tracked by ESXi Deltas are sent to recovery site (after initial sync) VM with snapshot(s) is recovered with snapshot(s) collapsed 40

vsphere Replication Limitations VMs must be powered on to replicate Automated failback is not supported vsphere Fault Tolerance is not supported VM templates cannot be replicated Floppy and.iso images cannot be replicated VM linked clones are not supported Physical RDMs cannot be replicated 41

SRM in the Real World Japan Disaster: Rolling Blackout Avoidance http://www.vsamurai.com/english/2011/3/23/real-life-dr-bc-with-vmware-srm.html I hope that the relative success of the running of the DR plan will also open the eyes of management to more prevalent use of VMware, specifically for the disaster recovery benefits. I can say, without going into detail, other critical systems (outside of the virtual infrastructure) did not fare as well! Thanks VMware! Thanks SRM! Mission accomplished... 45

Summary VMware vcenter Site Recovery Manager Automate DR Run Books Non-disruptive, granular testing of recovery plans Automated failover when it is needed most Detailed recovery plan history reports 46
