The two DD's that we have are configured as NFS. I can say that this greatly simplified our environment where they are used. We got rid of library sharing, rmt devices, smc devices (and copy pools, but that applies to both vtl and nfs). Now, these aren't real high throughput TSM instances so I can't comment on throughput for high use. Our going forward position is we want to use NFS for dedup systems. The one big drawback is Lan-Free. It's my understanding is that straight NFS is not supported for this. Our lanfree is all Oracle/Rman/TDPO/LanFree. Our discussions around this are to get rid of TDPO/LanFree and have RMAN write straight to a DD based NFS share. The big problem is to implement a 10gb Ethernet backup net when we already have the fibrechannel infrastructure. As I said, this is still in fugures discussion mode.

(DataDomain specifically) Sent by: "ADSM: Dist Stor Manager" <[email protected]> We've been told by consultants (these particular consultants shouldn't throw stones) that DataDomain customers running TSM are far happier running NFS than VTL, because DDRs are built primarily as file servers and the VTL function is an add-on. I can see the financial motive for staying with NFS (those VTL licenses aren't cheap!), but I'm skeptical about the implication that there's a functional or performance advantage to using NFS over VTL for a TSM server, in our case on AIX. Would anyone who's run both or chosen NFS care to comment? How much does it depend on your infrastructure or your needs for LAN-free?
