Hi Ram

The answer to your first question is that there are several products that
provide a virtual tape capability.  The Quantum DX line and EMC CLARiiON
Disk Library (http://www.emc.com/cdl) are good examples.  Legato lists the
virtual tape devices that they have qualified in their hardware
compatibility guides at http://www.legato.com/resources/compatibility/.

Hi All

I know the fact that Quantum DX100 disk array is treated as a "jukebox"
by Legato.  Quantum claims that there would be little configuration
changes to NetWorker on deploying this.  My questions are:

1.  Is there any other disk array box that can be seen by a backup
software as a tape library?  Or is it "Quantum" unique?

2.  Which one's a better option - letting NetWorker treat the box as a
jukebox or forcing it to see the box as a disk partition and then using
"file" device type to backup to it?  The first option apparently does'nt
require much changes to existing configuration.  Whereas I reckon, we
can save some cost by not buying the Autochanger Module of Legato
because its seeing it as a large HDD chunk?

Answers with any other added opinions are welcome.  Thanks in advance.

Rgds, Ram.
