VTL are expensive, however the limits I would disagree. We have a Sepaton (70+ 
Tb of usable - note not RAW) and I believe the limits on the Sepaton is in 
Petabytes.
 
Disk Staging is a nice concept, however with that you are placing a lot of the 
responsibility back on the admin. Fiber Zoning, installation, maintenance, etc, 
is all done by the admin in the case of Disk Staging.
 
In our group its just me and another UNIX Admin who are responsible for 
backups/duplication/restores for all the UNIX, Windows, SAN, NAS storage (about 
12.5 Tb of Data). I personally don't have time to deal with Symantec/Veritas 
support, which (lets be honest now) sucks lately. Sooooo - I am using VTL as 
crutch and "outsourcing" support to Sepaton.
 
To each their own........

I agree with Jim. Inexpensive disk used along with disk staging and some tape 
is a much better value than buying a VTL that will emulate a robot and drives. 
Before you buy a VTL you really need to ask yourself what specific problem you 
are trying to solve.

There are many VTLS on the market. And usually come at a steep price. Note
you are actually purchasing disk at a premium prices with limited
expandability. Adding cheap linux mediaservers with cheap raid disk is
arguably a cheaper solution.

Hi,

        What do you think about VTL?
        Are you using VTL? what model?

        EMC DL710 or NetApp VTL600?
        What about Storagetek?

Thanks in advance.

Juan
