I don't specifically know about the cybernetics but I have
customers with EMC and Crossroads SPHiNX VTLs. With these units the
connection to the VTL from the POWER System is usually Fiber or SAS.
With SAS you need to be very close. With Fiber you need a very robust
infrastructure to move data more than 'campus wide'. A couple of my
customers have private fiber that goes a few miles and use that
infrastructure to back up to 'remote' VTLs.
Beyond remote VTLs most use the local VTL and let that unit
Replicate the data over an IP network to the remote site. Of course this
takes additional time but the backup is done locally quickly and made
available remotely as bandwidth allows.

local, is anyone doing anything like this?? If so can you explain a) how
and B) how it compares to your local vtl save.
