We are using Redhat ( various versions ) and Netapp. We are not using any FC support to Netapp except for Media agents for CommVault to a VTL. That having been said; the NFS part should be good. We have had no problems with Oracle under RHEL 3,4 and 5 and NFS. Based on my FC experience with Cisco and Hitachi, I doubt there would be much problems with FC.
I don't see much of a differace between CentOS and RH except from support/version number issues. They are still a recompile of RH right?
But I would ask a follow up question or two, NFSv2? Fiber channel? What is the hardware? Is it on the support matrix?
Hi - One of our customers are using SLES on IBM blades, connected to the storage via FCP, with no internal dribes installed on these blades.
There are a few tricks to be aware of, but for over two years now, we have not had any failure on OS level.
If it was my systems, I would definetely consider of staying on SLES, wether it be 10 or 11. To upgrade from 10 to 11 on the outher hand should not be a problem, especially if your boot disks also reside on SAN.
If you are using FC, you can create a boot LUN, on SLES 10, and upgrade it to 11, to see what can go wrong, and if it works, roll it out to your other servers.
