tape library

when purchash tape library.
what should be my concern?

I don't know anything about that, so please give detail.

1.
I heard something from DLT,AIT or LTO.
does that all work with Oracle, does oracle backup
needs something special?

2. it is sun box, does that need something special?

3.
does all software like Legato networker or Veritas Netbackup
works fine with oracle, sun?

does hardware come with those software or i need to
purchase those software as well?

DLT, AIT, and LTO are all tape formats. Oracle doesn't care what type of tape that you use.

These tape libraries typically are connected to your master backup machine either through SCSI or Fibre connections. You can then backup any other node from across the network. No, you don't need anything special for a SUN.

Veritas Netbackup works great with Oracle's RMAN. My Veritas sales guy said that Oracle (the corporation) uses Veritas to backup their entire enterprise. Legato is a nice product as well. A mini-version is included with 8i. Both work well for backing up Oracle through RMAN.

Most tape libraries don't come with sophisticated software. You will usually have to pony up some $$ for the backup software in addition to a robot license (license depending on your library size).

Some of the larger vendors of Libraries are StorageTek http://www.storagetek.com/, ATL http://www.atlp.com/, and Spectralogic http://www.spectralogic.com/. You can also look to your Sun reseller for Sun badged ATL and StorageTek products.
