[Veritas-bu] Anyone using VTL
2006-08-01 15:29:55
I guess this begs the question to the audience and the people that have
put in VTL's ... what problems does a VTL solve that D2D can not?
I think the list so far is:
1. Administration is easier
2. Possibly performance
3. Compression (1/2 the disk of D2D)
4. I can use it to stress test a new NBU release
Anything else?

Juan,
I would have to agree with John Howard on this. We looked at VTL for our
backup environment but before we could see where to put it. We asked
ourselves what problem(s) are we trying to solve. In some cases the VTL
can give performance boosts where tape drives are the bottleneck.
However, if tape drives are under utilized it might logical
configurations (e.g, buffer settings, backup configurations) needing to
be adjusted or removed. It could be a limitation of host architecture,
or other elements such as networking, number of files being backed up,
type of data etc..

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
