I have been looking at different LSI MegaRAID cards for my undergoing SAN build, and I couldn't find any information about RAID controller redundancy, I have seen number of storage vendors ex, EMC equallogic they have Active/Active RAID card.
is it possible to setup similar controller setup?
if it is not possible, can I buy 2 cards from similar vendor/model/firmware and have it work as a drop in replacement/spear??
what is the recommended setup?? my plan is to setup this SAN up and not to visit that Data center ever!!!
