Re: Nexus 3K - 5K comparison

Totally Agreed with Joe - financial market people tends to buy Arista.
There is a reason for that. Believe me or not, most institutes who are in
share trading runs main application for pricebook update using multicast
feed.
If multicast feed gets disrupted for a few ms, it gets out of hands -
network administrator might get fired for receiving feeds a few second
later.
