Care to share your server farm experience?
There are many that do what you are trying to do as long as you understand
the limitations and differences in QoS/etc (compared to routers).
G1s, although being part of a software platform, are decent horsepower. If
you are looking at some shaping/policing down from gig you may want to be
careful (especially on multiple). But, if it's a 100mb line and you want to
play they will do fairly well.

Subject: [c-nsp] 3560G as WAN-aggregation-layer
Greetings.
I know this is going to sound pretty, well, lame. But...
I currently have a couple of routers (a 7204/NPE-G1 and a 3845)
front-ending my WAN connections, which are all metro Ethernet, mostly
gig ports which are policed at some CIR, or 100Mbit. The routers are
big, expensive, and really don't do much - oh, someday I would like to
do some QoS...someday.
So, there is this pile of 3560Gs in the corner. I've had
less-than-impressive experiences with them as server-farm access
switches, which is why they are there. However, I'm thinking that for
handling a handful (4-6) of Gig-Es/100Ms which are mostly not running at
capacity, as long as I distribute the ports out amongst the port ASICs
(so each line has the full 2Mbit TX buffer of the port ASIC to itself),
and as long as I don't do something stupid like put all 4 ports of a
4-port etherchannel in ports 1-4, they ought to be fine.
The switches don't need to do much - pass the traffic, run EIGRP, a
little light QoS. Our route table is tiny, relatively.
Am I going to regret this?
Conversely, how much can I really expect out of an NPE-G1?
