I am actually abandoning (sort of) all of my tape based solutions here 
in favor of a RedHat 9 box with 4 TB of storage.  I am getting two 3ware 
8 port RAID cards and 16 250GB drives running RAID 5 in a 4U rack mount 
for about $9k.  This will give me data archival as well as a backup 
solution.  I will use my old tape stuff to periodically (quarterly?) 
back up the RAID.

If you ever want to see a "REAL" tape solution - come to the 
observatory.  We have a _silo_ here that will hold ~70TB of data in a 
"near online" format using Sun's SAM/QFS software.  The filesystem is 
expanded to include any files on tape.  If you do a "cat <some text file 
on tape>" it will automatically grab the tape, read the file onto 
temporary disk space, spit out the file, and after a configurable amount 
of time - free up the disk space. Or something like that - Our SAM/QFS 
expert is in California.  EXPENSIVE though - and I do believe outside 
the scope of most applications.  Oh yeah - the silo is a StorageTek L700 
silo -> http://www.storagetek.com/prodserv/products/tape/L700e/
