As I said: at this point, I don't think there is consensus. Obviously you > will disagree ;o) The cost savings for 10GBASET is not an opinion it radically changes the economics of 10GbE and it does allow for 100M/1G/10G connectivity helping simply choices for ToR switches (one switch can do all of the above). I do agree it is not a consensus as to the 'best' technology but IMO 10GBASET will drive 10G adoption to the masses, with processor speeds increasing the bottle has moved from the CPU/memory subsystems of the server to the network I/O. In order to compensate people are going multiple 1G or single/dual 10G when it is cost neutral to deploy 10G instead of 1G it is a no brainer and with 10GBASET we are at that point. > > > switches.

I would not hold my breath waiting for 10GBASET in an SFP+ form factor.... _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
