I can't seem to find anyone that has small 1-2U solution that can do the full shake and bake. [snip]
If you don't need "all ports, all-line-rate, all the time" ... you could rig it with two rack units. I'd dirty it up with something like: First U: Brocade CER2k 48 (NI-CER-2048CX-ADVPREM-DC) 2x 10 gig + 48 sfp Second U: Arista 7148SX (DCS-7148SX-R) -- 48x 10 gig Ridiculous config #1231512: -take CER 2x 10 gig XFP, configure LAG & trunk host-facing and transit-facing vlans towards Arista 7148 -configure remaining 46 sfp+ ports as access interfaces for hosts on 7148 -configure static GRE on CER2k, transit neighbors, etc. -remember to crank mtu's on * -if box-router traffic is hashable, you could slum it with N x 1gig port LAG's for more bits/sec between the 7148 and the CER2k Of course, if two or more hosts are active, chances are good their inside-tunnel packets won't hash to either side of the 2x10g lag from the 7148. If your app is using IP in a more i-mix profile, the inner traffic could then be likewise flow-dense, meaning the hashing will effectively permit you to utilize all 20 gbits. Arista hashes on 7-tuples, whereas CER is l2+3+4 + labels (if doing mpls, etc), as of v5.1. I hear rumors that Brocbroc will be doing 1u N x 10 gig box where N will hopefully be >= 8 ints... of course, that doesn't help you now. Lastly, one could employ a 6716 blade + sup720b non-xl (for cheapness) in 6503E/7603 chassis... but ugh -- 4u, and almost 2x the runtime wattage of the ghetto-rigged config, and *still* internally oversubscribed to not-quite-40 gigs per slot! -Tk
