OpenWRT 10Gbps - HP t620 Plus & Dell QLogic 57810S Dual SFP+ Adapter

In this video, I am going to test out the HP t620 Plus Thin Client's performance with the Broadcom BCM57810s SFP+ 10GbE adapter. Let's find out if the HP T620P can handle 10Gbps throughput.
Eventhough the HP T620P has a Gen 2 PCIe x4 connector (in x16 form factor), I only get 4.9Gbps throughput with the CPU at 70% idle. During the test, the power consumption went up to 25W using the official HP power adapter with 220V AC - 50Hz.

Very thorough test. Wonderful content--looking forward to more!

[@VanTechCorner]

Glad you enjoyed it!

[@awarepenguin3376]

Thank you for the video! The T620 Plus really is a terrific platform.

[@miroslavkrumov]

Thank you very much for sharing all test, it is very useful. Please proceed with all differents boards which you have, it is very interesting to show us Openwrt capabilities. Thank you.

[@VanTechCorner]

Thank you, I will!

[@SomeTechGuy666]

Fantastic video !
I've been looking for an inexpensive way to route 10GB. It might not have worked on the T620, but there is always the T700 series.

[@paulotabim1756]

The BCM57810s operates at PCIe 2.0 . PCIe 2.0 can provide "real world" 4Gb/s per lane. So if the slot provide 4 lanes ( x4 ) the max transfer must be 16Gb/s ( gigabits per second ) limited by the sfp+ link to 9.4Gb/s . I sugest to try MTU 9000 since it reduce the packets/s in the interface and so overcome some limitations in I/O.

[@GTSpeac]

Van have you tried this?

[@VanTechCorner]

Thank you for the information. Unfortunately I don't have a chance to try this because it is returned the owner. (I borrow it).
I also tested this card with the Zimaboard (x86 SBC, Intel N3450, PCIe x4 Gen 2) and I managed to get 9.4Gbps throughput with the same setup (no touch the MTU). Maybe next time when I got another network adapter.

[@paulotabim1756]

@@VanTechCorner I have found some strange results using 10Gb/s NICs related to the PCIe configs in bios of the computer. Since the CPU load in your tests stay far away from 100% I guess that is some PCIe related config. Did you verify the config that the crd are using ? ( lspci -vv ) to see how many lanes and what PCIe level is being used .

[@VanTechCorner]

For some reason, I can't install the pciutils package on OpenWRT 21.02 to verify it (package is not found). However, I do have the same thinking with you. There could be something wrong with the PCIe, either the Generation is not properly detected or something wrong with the BIOS setting. I will carefully check it out once I got another card.

[@rottenfist220]

Thanks for putting Watt usage too. Imo it is one of the most important feature and this device really consumes so little for what it does.

[@VanTechCorner]

Yeah, I was impressed by what this 10 year old PC can do. Too bad that it doesn't have a SATA ports, else it will be great to run Promox/VmWare EXSI.

[@notthetypicalone8369]

thanks

[@GTSpeac]

Well done! Keen to try that NIC. Last week I completed the build with (TPLink 401) AQC107 and it works fine but get really hot and default 7-9w power use.... Mind you mine is not SFP

[@VanTechCorner]

Yeah, 10GBASE-T adapter are more expensive and draw more power compare to those 10G SFP+ adapter. Also, the 10G RJ45 switch is not cheap. Unless your home / apartment has ethernet cable running and you can't install fiber cable or DAC cable, the 10GBASE-T will be a a good option to extend the throughput, else I will not recommend it. For me, I will use either 2.5G RJ45 or 10G SFP+.

[@tompointdll]

@@VanTechCorner Interesting to know, then that's why i'm only at 10 to 15 w 👀

[@tompointdll]

Got one of thoes machine for myself, with a pcie to eth card, i never went over 10W idle and 13W gigabit throughput on 240V in france 👀but they are awesome and powerfull litle routers

[@VanTechCorner]

Yes it is. May I know what is the model of the NIC you are using? The SFP+ network adapter should consumes more power compare to the rj45 network adapter. With no adapter installed, during idle my HP T620P draw ~ 10W, just like yours.

[@TallonAM]

I know this is kind of non-sequitur to the main point of the video, but I use several of the HPT620plus for a lot of little machines in my home lab, and I haven't seen that RJ45 connector added before. Do you have a link for where you got that or a video on how to build it if it was a homebrew solution? Thank you

[@TallonAM]

Sorry, being ignorant. I just checked inside one of my cases and realized that's the mini-PCIe slot .. I should have remembered that.

[@VanTechCorner]

Yes you are right. There are mini-PCIe to 1 or 2.5GbE adapter available on the market. I have been using them and have no problem so far.
