Thanks William, and to everyone for all of your help.  You've given me tons
of information and loads of research to continue reading on.  I also have a
rep from IBM here on site to talk to me about the Ultrium system, since we
just bought a whole bunch of Bladeservers and other hardware from them, they
want a chance to help with this too.  So I'm going to compile all of this
and do some great research next week.

Thanks so much again!

Jennifer

Unless your L700 is really old I suggest you just arrange a new 
maintenance contract.    They are pretty solid.  You can have mixed LTO 
and DLT drives if you really need to.  Otherwise use LTO2, though you may
find that the NDMP backups cannot drive them fast enough, though it may
speed up if you use NBU 5.1.

I suggest you keep the 7 LTO1 drives, and fit LTO2 to replace the P3000
capacity - you will not need many to replace the DLTIV capacity.  The L700 
takes up to 20 drives.   The LTO2 drive can read and write LTO1 media, 
*but* NBU does not understand this at all - it has no concept of backwards
compatibility.  So you have LTO1 as HCART and LTO2 as HCART2, and they are
as separate to NBU as DLT and LTO.

StK are now selling the SN3400 router (a Crossroads box, similar to the HP
M2402 router) if you are using SCSI drives and a SAN.  For a master server
you might get away with a SunFire V440 - has an onboard GigE (but don't use
the ce0 port).  You need one CPU per active GbE connection, and also one CPU
per LTO2 drive...but in practice it will drive quite a bit. 
Depends if it just a master or master & media server.  Note that the
Netbackup for NDMP server takes a hit over the network, as the catalog
infromation comes in from the filer.  Could have V440 master and V240 media
servers....lots of options.  I don't think I recommend a Linux master, but
others may differ.
