Re: Nexus in DC?

Does the Nexus 7k support FCoE or fibre channel?
The 7k is nothing more than a big 10G switch.

The 5k is a totally different story and I definitely see the use of
that one. This is a fantastic switch, bringing 2 worlds together as it
should be, reducing cabling and introducing an entire new generation
of switches and network designs.

As for Cisco TrustSec, great feature, but you have to replace your
entire network you use it, still it's an evolvement of network
designs. I kind of miss the spanning-tree enhancements? Do you mean
multi-chassis etherchannels to create a loop-free topology? This is
something that is an awesome technique, this is where Juniper lacks,
but it's in the pipeline.

I personally think the Nexus product line is placed too tight, it can
only be used for a single purpose on one place in the network, but I
still see all the advantages and I would love seeing it evolve and
become mature.

(btw. Juniper EX4200 vs Cat 3750E, the Juniper is a lot cheaper when
you use 10G uplinks in a LAN design)

P.S. It doesn't hurt to be critical right? ;-) No offense! I always
prefer Cisco, but sometimes it's good to take a step back and see all
from a different perspective.
