These are all correct.

They do agree; they are both Brocade.

I was trawling eBay about 20 minutes ago and found that the Compaq
StorageWorks Fibre Channel Switch 8/16 was the same unit as the
SilkWorm II.  I found the latest Compaq firmware and it was the same
as for the SilkWorm Express/PowerVault 50F, so I upgraded the
SilkWorm II.  After that, the two switches synced up.
