  1. VMware Site Recovery Manager on NetApp Storage

  2. VMware Site Recovery Manager Business Continuity What is SRM? • A DR workflow automation product What does SRM do? • Simplifies DR, lowers cost and risk • Integrates VI3 with storage replication • Makes DR protection a property of the virtual machine • Allows a preprogrammed DR response

  3. VMware Site Recovery Manager • Collects VMs in Protection Groups at primary site • Executes an orderly Recovery Plan at DR site Protection Groups Recovery Plan 1 4 2 5 3 6 Business Continuity Protected Site (Primary Site) Recovery Site (DR Site) How does SRM work? • It is a plug-in for Virtual Center

  4. VMware Site Recovery Manager • It’s bidirectional • Sites can protect each other Protection Group Recovery Plan Protection Group Recovery Plan 1 1 2 2 3 3 Business Continuity Protected / Recovery Site Protected / Recovery Site

  5. SRM on NetApp Technology FlexClone SnapMirror® Protected Site (Primary Site) Recovery Site (DR Site) SRM is an elegant DR workflow solution. It uniquely addresses RTO issues. It utilizes underlying storage capabilities. Core NetApp® technologies are perfect for SRM.

  6. SRM on NetApp Technology Snapshot 2 Snapshot 1 NetApp Snapshot™ • Simplest snapshot model • Best disk utilization—no copy-out region • Fastest performance—no copy-on-write

  7. SRM on NetApp Technology FlexClone • NetApp FlexClone® • Instant writable copies • Leverages Snapshot • Low storage overhead Snapshot 2 Snapshot 1 NetApp Snapshot™ • Simplest snapshot model • Best disk utilization—no copy-out region • Fastest performance—no copy-on-write

  8. Example SRM on NetApp Environment

  9. SnapMirror Replication SnapMirror® Protected Site (Primary Site) Recovery Site (DR Site) Efficient—replicates 4k blocks Synchronous and asynchronous Leverages Snapshot™ technology

  10. SnapMirror Replication SnapMirror® Protected Site (Primary Site) Recovery Site (DR Site) Efficient—replicates 4k blocks Synchronous and asynchronous Leverages Snapshot™ technology

  11. SnapMirror Replication • Reversible for resynching SnapMirror® Protected Site (Primary Site) Recovery Site (DR Site) Efficient—replicates 4k blocks Synchronous and asynchronous Leverages Snapshot™ technology

  12. SnapMirror and Deduplication FAS deduplication on primary storage Data Deduplication SnapMirror® After Dedupe Before Dedupe Protected Site (Primary Site) Recovery Site (DR Site)

  13. SnapMirror and Deduplication Only unique data is replicated to the DR site • FAS deduplication on primary storage Data Deduplication New Data Written SnapMirror® After Dedupe Before Dedupe Protected Site (Primary Site) Recovery Site (DR Site)

  14. Vmware Requirements • Installed at BOTH Protected and Recovery Sites*: • ESX Server 3.0.2, ESX 3.5 or ESXi 3.5 • VirtualCenter 2.5 and Virtual Infrastructure Client • Site Recovery Manager 1.0 • NetApp Site Recovery Adapter 1.0 • Perl 5.8 (by default Perl is included in the SRM distribution) * This information is current as of Sept 2008, please check latest documentation for up-to-date support

  15. NetApp Requirements • Installed at BOTH Protected and Recovery Sites*: • FAS 2000, FAS 3000, or FAS 6000 Series Storage platforms • DATA ONTAP 7.2.2 or above • NetApp APIs use simple HTTP by default. To use secure HTTPS, you must set up SecureAdmin and ensure that ssl/ssh is running. • Because SOAP/HTTP/SSL is used, you must configure the firewall (if any) between Data ONTAP and Site Recovery Manager to keep the corresponding port open * This information is current as of Sept 2008, please check latest documentation for up-to-date support

  16. NetApp License Requirements • NetApp licenses required on Protected and Recovery Storage: • SnapMirror • iSCSI and/or FCP • FlexClone (required for creating flex clone volumes for Recovery Test)

  17. Supported Replication Products The following NetApp data replication products are supported with SRM on NetApp • Volume SnapMirror (async & sync) • Qtree SnapMirror The following is not supported • SnapVault • MetroCluster

  18. Supported Configurations • The following configurations are supported • NetApp FCP protocol • NetApp iSCSI protocol • NetApp FlexVol Volumes • The following configurations are not supported* • NFS protocol • Traditional Volumes (FlexClone technology is not available with traditional volumes) * This information is current as of Sept 2008, please check latest documentation for up-to-date support

  19. Configuration Guidelines • FlexVol Volumes should be replicated to only one destination • LUNs having multiple replication destinations cannot be failed over • NetApp SnapMirror replicates data at the volume or qtree level • Only VMs to be replicated should be contained in replicated volumes • Guest attached storage • software iSCSI inside Guest, SRM does not recover this storage • Applications running inside VMs are not application consistent

  26. SRM on NetApp DR Testing SnapMirror® Protected Site (Primary Site) Recovery Site (DR Site) SRM Recovery Plan testing

  27. SRM on NetApp DR Testing • FlexClone® volumes instantly created using very little space FlexClone SnapMirror® Protected Site (Primary Site) Recovery Site (DR Site) SRM Recovery Plan testing

  28. SRM on NetApp DR Testing Test Bubble Network • FlexClone® volumes instantly created using very little space FlexClone • Test Bubble created and VMs booted • SnapMirror® replication continues while testing SnapMirror® Transfers Continue Protected Site (Primary Site) Recovery Site (DR Site) • Instant cleanup SRM Recovery Plan testing

  29. SRM on NetApp Automated Disaster Recovery SnapMirror® Protected Site (Primary Site) Recovery Site (DR Site) Primary site being replicated to DR

  30. SRM on NetApp Automated Disaster Recovery • A disaster occurs • SRM Recovery Plan is executed • SnapMirror® stopped and storage presented SnapMirror® • Virtual machines started Protected Site (Primary Site) Recovery Site (DR Site) Primary site being replicated to DR

  31. Failback – Reversing SnapMirror If Primary storage recovered • SnapMirror “resync” in reverse direction • Only delta of data transferred • SnapMirror “update” during failback outage If Primary storage lost • Snapmirror “initialize” in reverse direction • All lost data transferred • SnapMirror “update” during failback outage See TR-3671: VMware Site Recovery Manager in a NetApp Environment

  36. Troubleshooting – Common Problems • Any issue with the Configure Array Manager • Verify the IP, username and password provided for the NetApp array is correct • If Array Manager does not recognize replicated LUNs • Verify SnapMirror relationship exists between the Protection and Recovery Filer and that the volume replicated contains LUN • During DR test no replicated datastore found • Verify Recovery storage has igroup type of vmware that contains ESX initiators • Verify replicated LUNs are not already mapped to igroup, SRM must map them

  37. Common Problems, contd. • General NetApp issues • Verify SnapMirror, FCP, iSCSI and FlexClone products are licensed • Verify igroup types are created with ostype vmware • Verify igroups contain ESX initiators • Verify FCP, iSCSI, and SnapMirror service is running at Recovery site • Any issue with SRM Test Failover • Check if flexclone is licensed on the Recovery filer or not • Verify that no non-replicated datastores exist on the recovery filer with the same names as the recovery datastore • Remember, only FlexVol Volumes support this feature

  38. NetApp Replication Management • NetApp Protection Manager Software • Monitors and manages SnapMirror® • Simple console eliminates status ambiguity • Gives holistic view of the environment • Reports unprotected data at risk
