The VTL can compliment a TSM installation where you have a real tape library (RTL) manager and RTL clients. Adding a LAN-Free agent to a RTL client is greatly simplified when the RTL client is also attached to it's own VTL. The RTL client can be the library manager for the VTL and share the virtual drives to the LAN-Free agent(s). With several LAN-Free agents, a VTL can easily be provisioned to provide additional virtual drives without impacting the RTL.

But when I learned from the Oxford symposium presentations that TSM would have its own dedup in version 6, and considering the cost of the vtl, I ditched it and ordered a lot more of SATA arrays for less money. I think in a few years after v6 is widely installed, VTL's won't look so good for TSM sites. Assuming it all works of course. your VTL vendor may just have been whistling past the graveyard.

Deduplicating VTLs fit better into NBU sites. TSM's progressive incremental methodology already reduces the data stream, making deduping VTLs less of a "win", though it can still be beneficial. My point is that VTL vendors may not look as positively on TSM as they do on other less-efficient backup solutions, because they don't sell as much VTL product to them.
