Update: NetApp has a KB article in NOW addressing this: Using SnapVault to Archive SnapManager for Exchange Backups Sets. Bottom line: You do not necessarily need ONTAP 7.3, Protection Manager and DataFabric Manager to send SnapManager for Exchange snapshots to a SnapVault secondary.
We recently acquired SnapManager for Exchange (SME) at my place of employment. We have an existing NetApp deployment consisting of two primary filers in a SnapVault arrangement with a third filer. The SME install is part of an upgrade from Exchange 2003 (on DAS) to 2007 (on Fibre Channel storage).
What we missed prior to purchasing SME: If you want to use SnapVault with SME, you need two additional pieces of software: Protection Manager and NetApp Management Console (part of DataFabric Manager, apparently). Here’s what p. 408 of the SnapManager® 5.0 for Microsoft® Exchange Installation and Administration Guide (NOW login required) says:
The following are the software dependencies for integrating SnapManager with
data set and SnapVault:◆ Protection Manager 3.7 and later
◆ NetApp Management Console 3.7 and later
◆ SnapDrive for Windows 6.0 and later
◆ Data ONTAP 7.3 or later
Wish I’d known that sooner.
(This is the point where some random NetApp fanboy pops down to the comments and fires off something about how NetApp is the greatest storage company ever, and if I’d done appropriate due diligence, I wouldn’t have missed this requirement. My advice: Spare us, smart guy. I’m writing this post to make it easier for other NetApp customers to do their “due diligence”.)
