So I have a few 10Gb Switches I need to test out using iPerf. I know iPerf can handle it as they have 10Gb public servers available on the internet, but can my machines handle it and can I get cheap NICs to do this also?
Machines I want to use are Dell 7010 with Core i3 2120 3.3GHz 2GB DDR3 – was super cheap from eBay. They are the MT (tower) so have 3 PCI slots that are full height, one x16, one (x4 electrical) x16 and one x1. The chipset is Intel® Q77 Express Chipset so v2 only, with only 8 lanes, so I assume the x16 slot is from the processor (also v2 16 lanes) and the x4/x1 from the chipset. (Note the DT has the same PCIe configuration but half height, and the SFF has only the x16 and x16 (x4 electrical).)
|PCIe version||Year||Transfers||Encoding||x1 speed||x4 speed||x8 speed||x16 speed|
So the x4 slot can do 10Gbit speeds, but the x16 would be better as it can do 64Gb/s – and also closer to the processor electrically so less latent. There’s quite a few dual 10Gb card cheap on eBay so maybe i’ll start by looking into them….
