[c-nsp] Cisco 3560X performance in the wild

[Ahmad Farisy]

Will it happened with 10Gb uplink also?

Did anyone experiencing 3560X with 10Gb uplink, how does its performance with 3 - 5 Gigs traffic?

I'm looking for 1U switch with 10Gb uplink and 3560X with 10Gb uplink is one of the opstion I have.


rgrds,

We've seen the output drops on uplink, two Gig attached hosts on the
3560X trying to push hard out the 1 Gig uplink.
With out-of-the-box no tuning or QoS, we'd see it struggle to hit 400 Mbps.
Having tuned it to dump all the buffers into one queue for the uplink,
we can hit 800 Mbps now.
This is also a function of how few and how bursty the hosts are, so YMMV.
