We run an 840c cluster with 3TB of storage as part of an AIX HACMP cluster. Prior to that the filer heads were 760's. Although we have had no failures to speak of, during testing we deliberately failed everything from the host rs6000 systems to the filer heads including all network hardware without a problem. (Well, we did have a problem with nfs timeouts during cluster failover because the application couldn't handle the error but we fixed that by making the nfs mounts hard.)

A quick question regarding NetApp filer clutering.
How well does it work?
Would you spend the money again?
Problems you've encountered that make it of questionable value.
We are putting more and more applications on the filer that are considered 24X7 when the filer itself is not. Granted, they are extremely reliable but the fact is that they have several single points of failure. I am looking at clustering filers as a way of fixing that. The other possibility is Veritas ServPoint HA on SAN.
Thanks.
