Cisco recommends use of Nexus switches as datacenter switches.
Nexus 5000 as the main switch, 10GE ports, Nexus 2000 as additional switches, connected to 5K using 10GE/20GE.

> I'm looking for some switch recommendations. We currently have 2950/2960's 10/100 with gig uplinks and are looking at upgrading. New features we'd like to get are:

> * 40+ gigabit ports
> * hardware acl support for ipv4 and ipv6 on ingress and egress traffic per port (just src/dst:[port])
> * "ip source guard" type support to restrict allowed mac / ip on each port for ipv4 and ipv6
> * qos on ingress/egress traffic per port for ipv4 and ipv6 (primarily just to throttle down from gigabit rates as needed)
> * jumbo frame support
>
> Some nice to have:
>
> * 10 gig uplink support
> * redundant power
> * reversible air flow (hot air coming out of network port side)
