I spoke with sepaton, emc, copan, IBM, and sun over the course of 4 months
starting in Jan. of 2006.  I choose to go with sepaton for a number of
reasons: they scale by size and PERFORMANCE (which is something none of
the others could match), price was good and maint. was reasonable, roadmap
for future products was excellent and wasn't dependent on what falconstor
was doing, and I liked the way they approached doing large block I/0.  All
the vendors accept sepaton just ran falconstor on their hardware and I
didn't like that approach. Copan I believe didn't use falconstor but their
unit was so heavy that it couldn't sit on a raised floor in the datacenter
if it was full. Sepaton was the only pure VTL vendor meaning that VTLs
were all they focused on. I have not had any problems since the
installation 3-4 months ago and like I tell others the sepaton vtl has
literally "given my life back" meaning that I am not checking TSM every
few hours daily even while on vacation anymore.  I don't want to sound
like an ad campaign for sepaton but in my opinion their leading the pack
and their support team is excellent as well.
