Fellow Members,

We are looking at upgrading our backup environment having added a couple of NetApps F880 filers with +/-10TB of data recently.  We already have a SAN storage island, so are looking at SAN attaching a STK L700E jukebox (housing either LTO drives or possibly 9940B drives), and linking the NetApp filers to the SAN also, thus allowing us to associate drives with Filers as needed. Initially, we then expect to use Legato to control NDMP sessions to enable the dump of the NetApp volumes to tape. 

My question is whether their are other Networkers who have similar conceptual solutions who can give an idea of the read/write throughputs we could expect for a single NDMP session, and what limitations/drawbacks there are when using NDMP. 

Any experiences welcomed,

Best regards,

Paul Broughton
