Nexus 3000 have 9MB buffers comparing to 1.3MB per port at
WS-X6748-GE-TX. Will ultra-low-latency switching decreases need amount
of buffers ? What about for using Nexus 3000 for long-distance
connection (eg. 120KM). Do I need more buffers for 120KM Ethernet that
for 10KM Ethernet ? (normal traffic , no storage)
