Thanks for the detailed reply. I was under the impression it was 32 paths maximum to any storage LUN not per host as this isnt obviously explained.
It looks like we can run bigger clusters as long as the 256 LUNs are not exceeded (is the 1024 LUN paths the same in 5.0?)
I am looking at maximums for 5.x but they are the same for cluster size and paths to a LUN maximum from what I read.
thanks
