John,
thank you for a reply. I am interrested in unicast traffic only, no L3,
no QoS requirements, low-latency is not needed, 10G ports only. Switches
would be used for a standard Internet traffic flows.
I am really interrested in these switches, but I don't want to buy a pig
in a poke..
Regards,
Jiri Prochazka

Hi Jiri,
The bandwidth to the fabric is dedicated and the expansion modules
have their own forwarding engines on them, so they are no different
than the base ports except that they can be swapped out.
What kind of traffic are you interested in running? Unicast,
multicast, QoS requirements? Do you have low-latency requirements?
10G or 1G? Do you know how much buffering you would need with your
traffic flows? Or is this mostly fact finding for now? Let me know
if you have any specific rumors as well.
Regards,
John Gill

Hi,
we are considering investment in a few Nexus 5596 switches. All Cisco
documents say it has 96 non-blocking 10G ports (for L2). Is it _really_
true? Can the switch reach throughput of 960 Gbps regardless the traffic
distribution? Is't there some hidden limitaion, which is not presented
by Cisco? :-) I've heard some rumors about this, but nothing particular.
First thig which comes to my mind is a doubt, if all three expansion
modules really do have 160 Gbps connection to the fabric..
Thank you for comments,
Jiri
