Nick weaver (of ICSI) just turned me onto them - http://www.cloudrouterswitches.com/RB260GS.asp?gclid=3DCj0KEQjw7b-gBRC45uLY= _avSrdgBEiQAD3Olx8_iFXJ_xKjZInc2T54XEu5VyMsTe42Rla3GTRKrkwwaAu2M8P8HAQ He also steered me to a nifty port mirroring POE passthrough device: http://www.dual-comm.com/gigabit_port-mirroring-LAN_switch.htm Haven't tried either yet, personally. It turns out that both he and I are using the nearly same model nucs for load testing, with a standard 2.5inch sata 3 slot, and 2 mini pcie slots for a half length and full length wifi device. "The D54250WYK1, which is a dual core, dual thread/core i5 based with 16 GB Ram and a 120 GB SSD). The only disadvantage is it doesn't include the "Vpro" lights out management suite present in the 3rd gen model." I am using the i3 versions. I'd written up a review of the one without the 2.5 inch slot here: http://snapon.lab.bufferbloat.net/~cero2/nuc-to-puck/results.html and later upgraded to the one with the slot, as sata is faster than msata, and the best wifi (atheros ath9k and ath10k) cards are all full length). These have e1000e cards in them, which support BQL under linux 3.6 and later, and although the (i3 at least) can't drive gigE to saturation without TSO, they have been quite nice and quite quiet so far, and have been giving solid results. They are a really good desktop, too, under linux, and mounting them on the back of the monitor (or, as I do, on a pegboard), is helpful too. > > -- > Mikael Abrahamsson email: swmike@swm.pp.se --=20 Dave T=C3=A4ht https://www.bufferbloat.net/projects/make-wifi-fast
