1 VMware Site Recovery Manager on NetApp Storage

2 © 2008 NetApp. All rights reserved. VMware Site Recovery Manager 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 2 Business Continuity

3 © 2008 NetApp. All rights reserved. VMware Site Recovery Manager How does SRM work? –It is a plug-in for Virtual Center 3 Protected Site (Primary Site) Recovery Site (DR Site) Protection GroupsRecovery Plan –Collects VMs in Protection Groups at primary site –Executes an orderly Recovery Plan at DR site Business Continuity

14 © 2008 NetApp. All rights reserved. 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 © 2008 NetApp. All rights reserved. NetApp Requirements Installed at BOTH Protected and Recovery Sites*: –FAS 2000, FAS 3000, or FAS 6000 Series Storage platforms –DATA ONTAP 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 © 2008 NetApp. All rights reserved. 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 © 2008 NetApp. All rights reserved. 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 17

18 © 2008 NetApp. All rights reserved. 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 © 2008 NetApp. All rights reserved. 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

36 © 2008 NetApp. All rights reserved. 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 © 2008 NetApp. All rights reserved. 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
