Maybe I should Google before starting a new thread. Here's the answer.

Greetings, I have an H11SSL and yesterday added two new fans. (Amazon link.) All the other fans in the system are 3-pin. The motherboard has four options for fan control: Normal, optimized, full speed, and heavy load. What those are supposed to mean I have no idea. Under full speed, the fans...

Edit: Everything below is... well, it's not wrong, except RDMA is actually not working for ANY hosts. Everything is going through IPoIB and it's awful. I thought it was working for other hosts but it is not. Original post: This host ("shark") currently has four RDMA-aware functions, and none...

Just an update: By setting force_link_speed to 7 and force_link_speed_ext to 30 in opensm.conf, I got the switch to force FDR10 on all ports. (Is there something more graceful than power cycling the switch for this?) Getting FDR10 did not allow my 40gbE optics to work though, so I'm not...

It's going to take me some time, since I've got no way to boot metal from an .iso right now (you're allowed to say WTF) but you're right, both are definitely installed and from different places: [root]@[carbon][08:28:06][~]# dpkg-query -S `which mstflint` mstflint: /usr/bin/mstflint...

I am running opensm. I customized one partition but otherwise it's running defaults. Using '-d lid-6 q' gives the same error: FATAL - Can't find device id. -E- Cannot open Device: lid-6. MFE_UNSUPPORTED_DEVICE

Certainly: [root]@[carbon][12:03:01][~]# ibswitches Switch : 0x506b4b0300527dc0 ports 12 "SwitchX - Mellanox Technologies" base port 0 lid 6 lmc 0 [root]@[carbon][12:03:23][~]# mstflint -d lid-0x0006 q FATAL - Can't find device id. -E- Cannot open Device: lid-0x0006. MFE_UNSUPPORTED_DEVICE...

Some things you should know first: 1. SR4 and LR4 transceivers use MPO-12 cable (SR "short range" multimode, LR "long range" single-mode) and MPO cables are really, really expensive. 2. There's probably no way to directly connect an SX6036 to any of your other switches. 3. The only real...

Holy freaking crap, what is the upload limit here?! Am I supposed to just upload thumbnails and link to my own server or something?

(Can I please attach an image? Thanks) ALSO! If anybody knows for sure which pin is SDA and which is SCL that would be very helpful! Finding ground was trivial.

Can anyone offer guidance, or "The Easy Way" here? I bought a pair of EMC Mellanox SX6005's before discovering the "beware these switches" thread. It's not the 6012, so I don't have to do the whole manual installation of MLNX-OS. But absolutely zero switch management is available in-band. I...
