that mirrors what our sales-droid told us last week, which was rather
irritating since six months previous he sold us a bunch of 6313s.  Seems
every time we turn around on our cisco gear we encounter another exception
to the rule.

That said, we're mostly impressed with the price drop of the 4-port 10GB
cards.  I would have liked to see a higher-density gigabit-port card;
maybe 32-40 gig ports in MTRJ jacks, for example, or using the new
mini-GBICs.
