I have been eying the Dell webmanaged Gigabit switches. They are
inexpensive, managed, support port mirroring, VLAN, QoS, and much more.
I am probably going to get the 16 or 24 port for testing. The forwarding
rates are an often overlooked spec. $202 (currently on sale) for 16
Gigabit ports is almost too good to be true for a managed switch.
I am in no way recommending this switch since I have yet to test it but
I certainly will give it a try.

Once upon a time I would say "Go Cisco", but I think Dell has come a
long way with their servers and switches.
