 We have about 12 Solaris  3-4 Win2003 servers we need backed up that
 are on an isolated network. They will have pretty slender policies which
 will not require a whole lot of index space. Probably something like 1-2
 full's a week with incrementals in between and 2-3 week retention. 
 
 Anyway, looking for some suggestions on a master/media spec that could
 handle this. Along with that client load, there will probably be SAN
 attached disk and a pair of LTO4 tape drives. 
 
 I don't have experience in small environments and I don't want to
 overkill it. Any ideas would be welcome. :-)

As a note, if you're going to use the disk for backups then duplicate off;

newer versions (6.5+ of netbackup can use SLP's (Storage Lifecycle Policies) to 
manage disk space but only with the AdvancedDisk, BasicDisk doesn't allow you 
to use SLP's

If you're running older versions of NB or you prefer vaulting this wouldn't 
apply.

from a DR standpoint it would make more sense to keep the EMM database on a 
local drive.  It's a pretty lightweight SyBase back-end and locally attached 
drives do fine. Do nightly Catalog backups and send the catalog backup to the 
NAS.

While you say if the NAS goes down you've got bigger problems, I would argue 
that you are compounding them by completely losing your catalog and having to 
rebuild it by importing tapes (depending on the media type anywhere from an 
hour to eight hours PER TAPE)  

You don't want your master server dependent on other systems for the catalog 
and you don't want you catalog backup dependent on your master server.
