[j-nsp] Qfabric

[Doug Hanks]

I'm more than happy to share, but first I need to know what I am allowed to disclose publically without a NDA.  We've been keeping this under wraps for the past 2 years for a good reason.  This _isn't_ a response to Nexus or any other technology out there.  Stratus is in a league of its own.

I think its a sexy solution however it falls short in areas to meet our needs. I think Juniper has something going for them, however its misses on a lot of contexts so far.

1. We no longer install structured copper in our data centers as we have gone fully top of rack. The edge Qfabric devices require a copper connection back to the routing engine complex. It needs to option to use sfp optics so we can do fiber for this link.

2. We still like most people deploy 90% GigE and will for the next year or so at least. Stratus needs a copper GigE offering. Even if we went full 10Gig for production interfaces, servers still need management connectivity which iare copper based and also 100Meg most times. Our account team suggested that we deploy EX devices to meet these needs, however that is a hack solution and something we won't entertain. Deploying EX's gets us back to the original issue of having remote devices all managed individually.

3. Stratus needs a smaller fabric offering. Scaling a network infrastructure with such a large risk, fault, change domain brings big concerns. It'd be nice to have a smaller fabric offering to compartmentalize the network a bit.

Doug it'd be nice if you could comment on my comments above if you have some insider info :) It'd also be nice if you could take this feedback to the engineering teams for their input. We already have our account team doing so, but another path of contact is always beneficial.
