I decided on a VTL because I wanted to have LAN-free backup ability and
compression with no load on the TSM clients or TSM server.  We have been
using Sepaton's ES2100 VTL for over a year with no problems (HP rebrands
Sepaton's product).

There have been numerous threads in this list about VTL implementations:
"File dev. type vs. VTL", "VTL experiences?", " Sizing for a virtual
tape library", "VTS or san disk storage", "Questions for people using
Virtual tape libraries"

The big advantage VTLs, and DEVCLASS=FILE volume virtualizers, have over
physical tape libraries are sub-second tape mounts, rewinds and
dismounts.  Combined with fast seek times those characteristics have
eliminated my need for collocation.

I have been very satisfied with the VTL choice.

Subject: VTL experiences?

Anyone out there have any good or bad experiences with VTL solutions.  I
was thinking about budgeting for 1 or 2 in order to phase out the
current san file system I am using for TSM disk storage.  There are
several vendors out there with VTL solutions most notably IBM and EMC.
My first choice would be to choose IBM but it is a new product and EMC
has been in the market longer.

 

Any comment or recommendation appreciated.

 

Thanks
