In the cases where people have done this - are extra DS14 shelves involved? I was told that the only way to get my tape library attached to a 270c with external shelves is with a fiber switch in the middle of it all.

Thanks,

Yep. We do this in one of our branch offices. Depending on your backup software, you may even be able to connect just one drive within an existing library.

We have an Overland Data NEO 4000 with 4 x LTO-2 drives in this branch. Two drives go to our Networker server for general system backups. The other two are cabled directly to their FAS270 (no switch). In this situation, media management is handled by the Networker server while the filer is responsible for spinning the data to the tapes.

One thing to watch out for is the ability to mix NDMP backups with other backups. Some software will let you do it, and other software will require that a drive be designated for NDMP only. Ours are dedicated here.

Hi

I don't have experience with SAN.

My question is:

Can I connect directly a SAN tape with a FAS270c, without the use of a
SAN switch between them?

Thanks

Luis
