Bill,
I am presently implementing the S2100-ES and S2100-DS VTLs by Sepaton
which are also TSM certified. While at present I am using them as
directly fiber attached devices to my TSM server, I chose a VTL solution
over a DASD solution

Sepaton is going to ship us a S2100-DS for testing with no commitment to
buy. Can you share with us your experience? Is it worth 3 times the
cost of setting up our own DASD. Is it as easy

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
From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On
Behalf Of Johnson, Milton
No idea about TSM's LANFREE being a limited use copy of
Sanergy.
It is not.
My understanding was that the big difference was in
the client code so that the meta data goes over the LAN to the
TSM server's
This is my understanding SANergy and TSM's LANFREE.

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.

BE VERY CAREFUL about the quality of disk you buy, if that is going to be

DO NOT THINK that you can't lose a RAID array; I have seen it happen, twice.
It depends TOTALLY on the quality
I agree... I even had a vendor CE pull one disk, figure out it was not the
right one, put it back in, then IMMEDIATELY pull the 'bad' disk. ... It took
days to rebuild the array from backups, and the CE was not allowed back into
the building, EVER!

You can backup the TSM DB to devclass of type file.
