perfSONAR User Q&A and Other Discussion

Though Paul's data show D15xx should be fine for 10Gb, has anyone tried Epyc 3xxx?  Price of Xeon-D, maybe 3-4x performance.  Maybe it could do 25/40/100 Gb perfsonar?

Subject: Re: [perfsonar-user] Xeon-D adequate for low cost 10G PS under $2,000 USD? If not, recommend cheapest 10G HW.

 

Hi Minseok,

I have ~25 perfSONAR testpoints installed around New Zealand based on Supermicro 5018D-FN8T systems, or that motherboard in a different case (DC data centres). Their X10SDV-TP8F motherboard is based around a Xeon processor D-1518. And they work fine for me.

We're running on Ubuntu 16.04, with only the testpoint packages installed on the machines.

I tried to do a simultaneous 10G test between two 10G nodes, 22 ms apart, to show you. But pscheduler was too smart for me. First one, then the other.

Running iperf3 from the command line on both hosts simultaneously, i get ~9.82 Gbits/s

Hi, all.

I'm planning to deploy 10~30 PS nodes in KREONET until next year. Most sites are connected with 1G, but I want to deploy 10G PS for the future. A budget for 1 PS node is under $2000 USD.

I found that Xeon-D processor contains 10GbE controller in the processor[1]. Supermicro Xeon-D solution has IPMI remote console. It is important for remote management. Its price is around $1500 at Amazon[2]. Unfortunately, I found that Xeon D-1540 gives poor performance on this video[3]. It shows 2.6Gbps on Windows 10 in the iperf test.

Is there any perfSONAR based one Xeon D-15xx or Xeon D-21xx? Is it recommendable for 10G perfSONAR? If not, could you recommend low cost one?

Best Regards
