Milton,

Do you realize that the "TSM's LANFREE" technology you are refering to
is in fact Sanergy?  TSM just gives you a limited use copy of Sanergy
when yuo turn on the LANFREE stuff.  That was why I questioned how you
were going to do LANFREE without Sanergy.

That clears that up.  Thanks.

A virtual tape library operates and connects just like a physical tape
library in a SAN environment.  The VTL, TSM server and your client are
connected to the SAN so a LANFREE back-up works using TSM's LANFREE
technology.  Since the topology is conventional you should also be able
to add a SAN Data Gateway and do a "server free backup".  The key is
that a VTL is just a conventional fiber connected library with really
fast robotics and drives. Yes, you do need to make sure that the VTL
plays nice with TSM, so make sure your choice in VTL is TSM certified.

I am not quite sure what you meant by "with TSM you can use disk only
for backups instead of onsite tape".  I do not see any reason why you
can not use FILE device types for both primary and copypool stg pools.
Of course if you actually want to move a copy of the data offsite, then

you would need some type of removable media such as tape.

For me two of the attractions of a virtual tape library are being able
to do lanfree backups without using Sanergy, and having the VTL do
compression.

Hi Milton,

I am not sure how you get to do Lan-Free without using Sanergy.  In
order to do that wouldn't the VTL have to have some kind of similar code
as Sanergy and then the question is does that play nicely with TSM.  Or
am I missing something really obvious here?  Please explain how you will
get Lan-Free to work in a TSM environment without the Sanergy code.

Thank You.
