One of the biggest issues with Brocade is when I have device/port issues I first see an error in the main error report, and then have to visit the fabric log to start figuring out what is actually going on. The Fabric log is incredibly unintuitive and frequently useless.
So you have to upload support saves and get told "slow draining devices"..... but they can't point them out. Just they exist.
So now you come to the situation where you're trying to find a root cause and all Brocade can do is vaguely point out you have something somewhere.
So the SAN gets a bad name and management gets sold on FCoE.
