SnapManager for VI 1.0 (Virtual Infrastructure)
In Vmware environments:
1. snapshots may not be granular enough.
2. vmware is best in NFS than ISCSI.
3. Traditional backups disadvantages.. (i) dont match your VI (ii) No cpu power left on the server.
4. Recommended.. only 4 snapshot copies a day.
5. how SMVI works.. (i) Backup initiated. (ii) Vm snapshot copy created. (iii) Snapmanager for VI triggers instant NetApp snapshot. (iv) vm snapshot removed.
6. only VMFS/NFS support. No RDM support.
7. Protocols - ISCSI, FCP, NFS.
8. snapmirror is integrated.
9. Backup scheduling and retention policies
10. SMVI only support netapp storage.
11. Efficiently meet the backup and DR needs of your ESX environment. (i) Leverages netapp snapshot tech (ii) provides a way to restore VM and data stores
SnapManager provides rapid online backup and near instantaneous restoration of Exchange databases by using online Snapshot™ technology that is part of the Data ONTAP® software and integrating the Microsoft Exchange backup and restore APIs and VSS. SnapManager can also leverage the SnapMirror capabilities of storage systems to provide on-site or off-site SnapManager backup set mirroring for disaster recovery.
SnapManager supports the following data management capabilities:
· Migrating Exchange databases and transaction logs to LUNs on storage systems
· Backing up Exchange databases and transaction logs from LUNs on storage systems
· Verifying the backed-up Exchange databases and transaction logs
· Managing the SnapManager backup sets
· Restoring Exchange databases and transaction logs from previously created SnapManager backup sets
· You can use SnapManager to create offline archives of Snapshot copies containing Exchange backup sets for long term or remote backup storage.
Three different archive methods are supported:
1. Manually initiated archival using NDMP (Network Data Management Protocol) or the storage system's dump command
2. Manually initiated archival using a Windows backup utility
3. Automatic archival using the Run Command After Operation feature with your backup operation
The SnapVault software can be used to archive backup sets.

VIFS on NetApp
Vifs (Virtual interfaces) are used for multi-homing and load balancing. A Single mode vif is for failovers only and Multi-mode vif is for load balancing, but you can use a combination of multi-mode and single mode to be fully redundant and load balanced.
For more information on VIFS please check the NetApp now site.
To create a single mode vif
vif create single sample-vif0 e0a e0c
To configure an interface to use a vif
ifconfig sample-vif0 `hostname`-pub mediatype auto netmask 255.255.255.0 wins partner cluster-vif0
Make sure you reference the vif name not the interface name
To view all interfaces including vifs
To view a single interface or vif (note you must view the vif in order to see ip address)
Ifconfig sample e0a
To view all vifs status
To view single vif
vif status sample-vif0
To view statistics
vif stat sample-vif0
If you need to remove an interface from a vif
vif delete sample-vif0 e0c (This will remove e0c from sample-vif0)
To favor one interface in a VIF (this always be the one that's used if up, if it ever goes down and then comes back up it will fail back to it)
vif favor e0a
