Hi,

on a two node cluster, Do I need two seperate SAN boxes If
i have to run SQL Servers on a Active/Active clustering?.

Regards

Chip

Nope. You will need different LUNs on the SAN, but not different SANs.

Cheers,

Check these out for some insight, but your hardware vendor is really the
best place to start.

Real easy way to think about this. A LUN is a virtual disk on the SAN
side, but maps as a physical disk on the OS side. Almost like a RAID
container, but with an extra layer of abstraction in the SAN between the
logical disk construction and the underlying physical RAID disks.
