I wouldn't call FCoE ethernet, it's really not. Unless you can plug it into a regular ethernet switch it's not ethernet in my opinion.

ranted about it last year

Not that I have a problem with FC, but I do have a problem with folks out there trying to blur the lines between FCoE and regular old "E" as if they were somehow the same thing.

Some vendors out there are pitching ATA over ethernet as well, never used it but at least they're using real ethernet.

Hi Nate,
I'm not sure that converging regular and disk I/O traffic on the one NIC is such a great idea. I prefer to segregate FCoE traffic and IP traffic separate NICs, switches, common parts inventory.

FYI: AoE uses MAC addresses and is not routeable, unlike iSCSI which is routeable. I've only used AoE with 1G-E so can't comment how it works with 10G-E.

Hi Chuck,

Interesting article - and a topic that I have been tracking for some time. The whole discussion around protocols, pieces of wire has been an interesting one...

Wrote a bit of a blog article on the topic here: http://www.stuiesav.com/2010/05/confusedobject-storage-bycast-bygone.html

and guess i came to the same sort of conclusions - ethernet will ultimitely (and is already win).

10-Gig-E is becoming commodity and with it performance and all the good stuff that allows us to make choices once more.

It will be interesting to see how much DCE / DCB (What ever you want to call it) and FCoE will become the defacto Vs people starting to use file systems again (i.e. NFS / CIFS etc) over more traditional 10-GiG-E...

Its also very interesting to watch the convergence of technologies starting to happen in the end storage device (merged technologies around Clariion / Celerra / Atmos etc being case and point)... Things are getting really interesting...

Thanks for the article!

Nice article. Very meaningful. BTW thanks for sharing us information about protocols. I've been surfing for this too long.
