I am new to clustering. I have a 2 node cluster running great on our 4tb
SAN. I need to add 2 more 2 node clusters, for a total of 3 clusters (2
nodes each)

Does each cluster need to be hidden from eachother on the SAN (ie LUN
masking) Or can they all co-exist happily as long as I have a seperate
SBD partition for each of them?

Any advice? Thanks
