Site Recovery Manager 5.8

Terminology Acronyms and terms we will be using– SRM (Site Recovery Manager)– ABR (Array Based Replication)– VR (vSphere Replication)– VRMS (vSphere Replication Management Server)– VRS (vSphere Replication Server)A1– “SVR” (Standalone vSphere Replication i.e. NO SRM involved)CONFIDENTIAL9

Slide 9A1Do we need SVR? Lots of acronyms for the audience to keep track of already.Author, 8/9/2014

What’s New in SRM 5.8

What’s New in Site Recovery Manager 5.8DR for the SDDCEnhanced ScalabilitySimplified Operations Self-service, policy-basedprotection – vCAC integrationthrough new vCO plugin 5x scale of protection – up to5,000 protected VMs pervCenter Server* Converged UI with vSphere –vSphere Web Client plugin Software-defined storage forDR – Virtual SAN integrationthrough vSphere Replication 2x scale of recovery –concurrent recovery of up to2,000 VMs per vCenterServer* Performance enhancement –storage stack improvementsreduces RTO Simplified IP addressmanagement – rule basedcustomization at the subnetlevel Faster installation –embeddeddatabase option (vPostgres)* Scale supported with array-based replicationCONFIDENTIAL14

vCAC and SRM Workflow Load SRM plugin package into VCO Run workflow to attach SRM postprovisioning to a vCAC Catalog Item– Can do this against a ‘template’ CI Now when provisioning that CI, SRM priority and custom properties (callouts, etc.) will beprompted After deploy the workflow carries on:– Finds protection groups for the target datastore– Adds the VM to the protection group and associated recovery plansCONFIDENTIAL16

vCAC IntegrationSRM protectionexposedthrough vCACPortalCONFIDENTIAL17

Runs a Standard VCO Workflow after ProvisioningCONFIDENTIAL18

Not Just for vCAC Though The VCO plugin for SRM offers many other workflowsas well:– Create protection groups and add VMs– Find protection groups by datastore– Add protection to unprotected VMs in a replicateddatastore– and almost anything else the SRM API exposes cannow be accessed through the VCO plugin.CONFIDENTIAL19

vSphere Replication Recommendations Set RPO to longest acceptable value– 15-minute RPOs: Just because you can, does not mean you should Leave VSS quiescing disabled unless really necessary– Majority of apps recover well from crash-consistent copy Configure minimum acceptable number of MPIT recovery points– Fewer recovery points faster recovery time, less storage consumptionCONFIDENTIAL55

vSphere Replication Simplifies DR for vSphere What is vSphere Replication (VR)?Site A (Primary)– VR is VMware’s proprietary technology forhypervisor-based replication of vSpherevirtual machinesvSphere What are the key features?– Asynchronous replication with customizable RPOvSphereReplication– VM-centric management, storage-agnostic– Multiple point-in-time recovery (MPIT)Site B (Recovery) What are the key benefits?– Simplifies replication of virtual machinesvSphere– Eliminates storage hardware lock-in– Integrated with the VMware product stack– Included with vSphere at no additional costCONFIDENTIAL61

Workloads NOT Suitable for vSphere Replication?Shared inter-site components AD, DNS, LDAP Typically shared across sitesvCenter Server Official solution, “Heartbeat” Could be done, unsupportedHigh Churn & VSS Usually aggressive RPO VSS Quiescence time overheadInter-VM write order fidelity Array Based Consistency GroupsZero RPO VR Range is 15min-24hrs Use array replication 15minUnsupported Check release notes! pRDMs, multi-writer VMDK’s etc.CONFIDENTIAL62

vSphere Replication Appliance Single Appliance to download– Same appliance used in SRM and non-SRM deployments– Initial instance performs two roles Role 1 - vSphere Replication Management Server (VRMS)– Configuration management– Only one appliance per site performs role– Warning if attempt to configure 1 per site Role 2 - vSphere Replication Server (VRS)– Manages replica instances– One or more per site (up to 10 max)CONFIDENTIAL72
