I have a customer with a Brocade SAN which should be migrated to MDS; at the moment he uses port-based zoning.
I proposed to switch to pwwn based zoning, but customer doesn't like it, although he cannot give me any reason why not.
How popular is port-based zoning ? I hardly could find any customer installation doing that !
I agree 100%; there are a few things, that mandate pwwn zoning: eg. device-alias and NPV.
Reg. security: with port-based zoning: miscable a server, and the zoning is ok; the only feature which avoids the disaster is masking/mapping on the storage device. (btw. would this not also apply to a rogue server, unless you also fake the pwwn ?).
