Supermicro X9SRW-F small riser mounting adapter (#P24)

More fun with the Supermicro X9SRW (and we’re still not done yet!)

The two X9SRW machines that I got had the same CPU and RAM situation, but one of them was in a 815 (1U) case, and the other one still is in a 825 (2U) one. I scrapped the noisy 815 for my board and allocated the more spacious 825. Fans are not the only thing that differs, though, as the added height also caused Supermicro to exchange the riser card for a different one. While the top riser is just an angled PCIe x8 connector (high up to make room for some heat sinks underneath), the bottom one is a WIO type that distributes 32 lanes in total. […]


Mellanox ConnectX-3 MCX311A-XCAT 10GbE and Solaris 11.3 (WHL #42)

The heat. F*ck me.

I think post #42 deserves something nerdy. More nerdy than usual. Glad to report that I just bought something suitable – two Mellanox SFP+ cards (MCX311A-XCAT), capable of 10GbE over fibre (IEEE 802.3ae) and per DAC cables (not even sure which 802 that is – 802.3ak is Twinax as used in DAC, but thats quad-Twinax as used in CX-4 connectors, like Infiniband does). 55.00€ delivered from the Netherlands, as fast network connections are “Neuland” in Germany and therefore carry a heavy premium. Slap on some 1.5m of compatible FS.com […]


Mini PCIe Module QCA9880 WPEA-352ACN 802.11AC Dual Band Wireless WiFi network card support Linux (WHL #39)

While I’m in the “X doesn’t do Y, so let’s hotchpotch DIY something to get Z running” mindset, let’s release something else that I’m slightly bitter about. WiFi network cards. [scroll down to the first image to skip my rambly introduction]

I’m not a big fan of Intel for their business practices, but when it comes to Consumer/Prosumer network cards, Intel is basically the brand to get. I’m running a CT Gigabit (82574L) addon card in my AMD ZFS server, and my old Thinkpad has something similar (82567LM) built in. […]
