First thing you need to wrap your arms around is that to Networker, a
VTL is just another jukebox.  Therefore, whatever you can do to a
physical library (staging, cloning, etc), you can do to a VTL.  Took me
about 5 months to get that figured out.  

We currently are using an EMC CDL 710 for our VTL and I have 1 ADIC
I2000 created on it.  We also have an ADIC I500 in house for our
physical tape library needs.  The I2000 runs 32 LTO3 drives and the I500
has 4 LTO3 drives.  The intent of the I500 is to have that be at our DR
site (in construction/planning stages), but for now, it sits in the
datacenter.

All of our backups go to the CDL first and then will be staged to the
I500 (still completing this process).  I was doing automatic cloning of
the backups from CDL to Physical, but that was basically duplicating
savesets and staging will delete the savesets once they are moved over
to the physical storage, then the physical tapes move to our offsite
vaults.

That's a 1000 foot view of our environment today.  If you need/want
more, just ask.

Goodluck!

Subject: [Networker] new to Virtual Tape Library - what are the
benefits?

Hi, I am new to the use of VTL (clariion disk) and I would like to know
what the benefits of using the VTL are over using Advanced Disk Device.
  Also, is there such thing as staging on a VTL? If not then what is the
best way to free up disk space when it is full - is it cloning to tape
and then re-labeling the virtual media.
   
  Any examples of how you are using VTL and managing the media would be
appreciated.
   
  Regards, Mark
