Sounds like we are both at the same stage.
We are not using RDM's yet, however when it comes to exchange we will have to, or I may just stick with using the Microsoft Iscsi initiatator from within the VM, not exactly supported, but I know of other people doing it.
We have migrated 8 machines so far, into just one datastore and have not seen any performance problems at all, although most of the machines have very low IO requirements.
We are using a script to snapshot and then replicate using snapmirror, it works very well, however our Virtual Centre server is also a VM which was causing a few problems with the snapshots on the VMware side not being removed, but moving this to a separate datastore seems have cured the problems, even SQL doesn't seem to have a problem.
The script is the one written by Evan Battle, that is in the newest netapp docs on VMware. I did have a few problems with ssh to the filer, but we are now using rsh and it seems to be ok.
I don't know how you have setup your virtual switches on the ESX side, but I got some best practice information out of VMware on that subject.
Each of our ESX IBM3550 host servers have 6 Nics, connected as follows.
2 Nics for service console VMKernel for Vmotion, load balance using Virtual port ID
2 Nics for Virtual Machine network, load balance using Virtual port ID
2 Nics for ISCSI (Service Console and VMKernel), load balance using IP Hash
Hope this helps....

Hey Matt... I am actually doing the exact same thing on a FAS 270.. I have migrated about 7 servers so far.
Are you using RDM's (remote device mappings) for the Virtual Machines? I actually just created 2 200GB LUNs on the netapp to use as Datastores and have not had any performance issues.
Just wondering what your experience with RDM's are.. I added one into a virtual machine.. It just lets you map a LUN directly to a Virtual machine.
Has anyone out there used the netapp script to capture a VM snapshot?
Thanks, Forest

Still working by the looks of things.
busy in process of migrating all our physical severs to VM, stored on a iscsi lun on a FAS 270.
For those that want to know we are using the software iscsi initiator within ESX and have not had any problems so far.
cheers
matt

I've noticed that I'm still subscribed, but have received no email since July 4th. Everyone didn't trade their NetApp gear for something else while I was out of town did they?? J
