Apologies if this is addressed somewhere, but I was unable to find any references beyond having the tape libraries also attached via FC. I'd also like to apologize if this is a stupid question; I'm not that well versed with the capabilities of the NDMP protocols.
We have a 4 drive LTO4 tape vault that is directly connected to our Commserve via SAS. Presently, we are using NDMP over Ethernet to backup our Netapp Filer to tape, and while it works well enough, we occasionally have some throughput issues if the filer becomes busy or if there's a lot of traffic on our switch fabric.
We are in the process of bringing a fiber channel SAN live with the netapp filer acting as the storage head. We are also looking at installing a fiber channel HBA on the next iteration of server hardware for our commserve, and locating the spool disk on the san to eliminate the Direct attached storage we currently use as a spool disk for our remote server backups. Budgetary limitations limit us to updating the server hardware and not replacing the SAS drives on the tape vault with FC drives, otherwise I wouldn't be posting. :)
It is possible for us to backup our netapp filer using NDMP across the faster FC connection, or it is limited to ethernet and IP networks only?
