Re: Nexus in DC?

I know you can enable 'performance mode' so the linecard shuts down 24 ports
of the linecard.
Why can't the EX compete to the Nexus? The performance is quite the same if
not better as the Nexus line and totally owns the Cat6500 in terms of
performance. Still the Cat wins it on service modules and the vast amount of
line cards.
And btw. the EX8200 already has 320Gbps backplane connection for all
linecards while the Nexus gets support for 230Gbps linecards end of the year
and I don't even want to know when they start thinking of 500Gbps to finally
offer true non-blocking 32-port 10Gbps linecards :-)
The only thing the EX8200 lacks is support for some sort of multi-chassis
etherchannel, this is on the roadmap to be released soon though.
