Summary

  • 18 March 2009
  • Before switch to jumbo frames, performance to nettest10g.usatlas.bnl.gov 3.2 Gbps (8 streams)
  • Single stream performance ~ 1.2 Gbps; in general, multiple streams needed with 1500 frame size
  • Local performance for these UC hosts: ~ 5 Gbps (10G -to- 10G hosts, both at UC). This should be higher - need to look at NIC settings on these hosts.
  • We get 6 Gbps from IU to UC (as good as local performance), but 4 Gbps (single stream) (jumbo frames end-to-end)

Jumbo frame testing plan

From: Bigrow, John F [mailto:big@bnl.gov] Sent: Friday, March 13, 2009 2:15 PM To: Ernst, Michael; Rob Gardner Cc: McKee, Shawn; Burstein, Frank; O' Connor, Michael P (ESNET); Hockett, Roy; Yongrui Tang; Anita Nikolich; Ron Rusnak; Yu, Dantong; O' Connor, Michael P (ESNET) Subject: RE: [Usatlas-grid-l] MTU setting at bnlsite-bnlmr1.es.net(198.124.216.178)

Good Afternoon Everyone;

Sorry I didn’t get a chance to reply earlier but I’m working With ES net on our near term site upgrades.

Thanks for your comments and insights they were quite helpful.

Can I propose we adopt the following methodology to test this capability?

One morning next week, I will activate the jumbo frame features. I have to notify the BNL community about network changes. This is an internal policy. I’m thinking Wednesday morning at 09:00 EST. I’ll activate the jumbo MTU on both the 192.12.15.0/24 and U Chicago links. This will allow us to test access into this network here at BNL. In the interim, I have A 10 gig host at IP 130.199.3.7 (newmon.bnl.gov). This segment is the first entry into the BNL normal campus LAN. This host will keep it’s current 1500 byte MTU as will that segment. I currently have an iperf server running (iperf -s -p 5010) there on port 5010. Dantong Yu has a 10gig box on our atlas segment 192.12.15.25 (nettest10g.usatlas.bnl.gov) that we can also run iperf tests to. That iperf is port 20000. When I make the switch next week to support jumbo frames, he can set his platform to 9k mtu and we can test against these hosts again. This will give us a baseline set of measurements. At the end of the day, I can set the MTU back to 1500 if desired.

If this plan sounds ok with everyone I’ll make an internal announcement informing the BNL community about the changes for Wednesday next week. I’d like to run the same tests to your systems from BNL. Also on at the University of Chicago if that’s available to. Can you email me back with the hosts and services on your side and if the day and time is ok with you?

Disclaimer.: This is a production network so if this testing impacts or causes other performance issues I will have to undo these changes.

Thanks

Have a good weekend everyone John F. Bigrow

Hi Rob

From the last two days some random hits from me back to you!!!

Keep in mind, I think this link is BW limited to either 1 or 2 GB.
