FC or FCoE, which is "better"? Sometimes not the issue.
A few years back I was approached by my then Chief PHB to produce a design for our next gen datacentre based on segregated Ethernet and FC. A week later he was back asking for the same using FCoE and one using iSCSI. His reasons were simple - he was playing the vendors off to see which would get him the biggest/best golf day! In the end, after three such outings, we ended up with a hybrid design that just about satisfied everyone.
