I am a newbie in the SAN world so hope am asking the right questions.
We are looking into replacing our aging SAN. As part of the replacement, managemnt is thinking of placing a secondary SAN at one of our remote locations for backup & DR purposes.
My question revolves around providing connectivity between the two SANS. I have been asked to look into a dedicated point-to-point connection for the SAN replication. Not counting the actual SAN hardware, what other hardware would I need? Am I bacically building an independent network for this? Why this route instead of over our corporate WAN? Any good recommended reading for learning about the SAN world?
