Seconded. > Note this isn't an OpenBSD problem -- the 5018As are just bad hardware. > (They also have APIC interrupt issues, most likely due to a buggy ACPI > implementation.) > > We replaced all our SYS-5018A-FTN4s with SYS-5018D-FN8Ts. I am fairly happy with SYS-5018D-FN8T. My main gripe is that they didn't put the serial port on the front panel, it's only on a motherboard header which is under where the PCIE card sits. The only simple way to take it out of the box ends up losing you the PCIE slot. My usual warning, with the IPMI controller, make sure you set it to dedicated LAN only. Otherwise it will silently share the first motherboard LAN if the management port is not plugged in. Even if you don't plan to use it (maybe *especially* if you don't plan to use it) you don't want that open to unfiltered traffic. > I can't speak to the other models you mentioned. > > As for network throughput, we did test a pair of 5018As with 10-gig > NIC cards.
