each other. Virtual machines can be quickly and easily collected into groups that share common storage
resources and can be recovered together.
Figure 1 SRM Site Components
Upon the execution of a disaster recovery plan SRM will:
• Quiesce and break the NetApp SnapMirror relationships.
• Connect the replicated datastores to the ESX hosts at the DR site.
• If desired, power off virtual machines, such as test/dev instances, at the DR site, freeing compute
resources.
• Reconfigure the virtual machines as defined for the network at the DR site.
• Power on the virtual machines in the order defined in the recovery plan.
• Execute any custom commands that have been stored in the recovery plan
Upon the execution of a disaster recovery test SRM will:
• Create FlexClone volumes of the FlexVol volumes on the DR storage appliance.
• Connect the FlexClone volumes to the ESX hosts at the DR site.
• Connect the virtual machine network adapters to a private test bubble network.
• Reconfigure the virtual machines as defined for the network at the DR site.
• Power on the virtual machines in the order defined in the recovery plan.
• Execute any custom commands that have been stored in the recovery plan
3.2 NETAPP SNAPMIRROR
NetApp SnapMirror™ provides data replication in a SRM and NetApp environment. Built on NetApp
Snapshot™ technology, SnapMirror replication is extremely efficient because it only replicates the 4KB
blocks that have been changed or added since the previous update. Additional efficiency is gained when
SnapMirror is combined with FAS deduplication. When FAS deduplication is utilized on the primary storage,
only unique data is replicated to the DR site. Additionally SnapMirror Network Compression can provide
native on wire compression of data sent over the WAN. These technologies result in significant
telecommunication and storage capacity savings at the DR site. SnapMirror is easily configured using
NetApp Protection Manager software, the Data ONTAP® CLI, or FilerView® GUI.
For cases when primary storage is not completely lost, SnapMirror provides an efficient means of
resynchronizing the primary and DR sites. SnapMirror can resynchronize the two sites, transferring only
changed or new data back to the primary site from the DR site by simply reversing the SnapMirror
relationships.
