Arista DCS-7050TX-72Q-F | 48-Port 10GBASE-T | 6x 40G QSFP+ | dual PSU | Rails Is sort of what I'd ideally want, as far as sufficient qsfp+ ports goes. 4 ports would leave no room for any kind of expansion. (Assuming that this supports 40gbe, I have a separate infiniband network for rdma...

The why is simply because my definition of quiet has, so far, not even remotely been achievable with original fans or even with smaller noctua's. A 200mm noctua's sound level is below background. Unless the environment is very quiet, you simply hear nothing, which is what I'd like to achieve...

Hello all, I'm considering purchasing something like a Arista DCS-7050QX-32S-R 40GB QSFP+ 4x10G 3 Layer Switch for home use. I don't hae any experience with Arista but going by the specs this seems a reasonable way to have 40Gbe between the machines where I have qsfp cards and 10gbe for...

I have to say this is looking like an attractive option. The fact that it's really just a slightly slower 7763 makes it really interesting. With three water cooled videocards, two nvmex4 cards, a connect-x and a 2x10gbe on a H12ssl-i it's more or less perfect to run all the VM's I want. Assuming...

Well, I'm certainly curious. A 64 core Zen 3 Epyc is looking like a reasonable fit for the weird setup I'd ideally like to put together. Hope it all works!

Thanks for the replies. I'm beginning to come to the conclusion that it's all a bit iffy for that amount of money. I'll just keep looking around, see what happens to the zen3 epyc market when zen4 epyc actually becomes available.

Hey all, I'm considering some upgrades and I spotted this on ebay: Supermicro H12SSL-i Motherboard, AMD EPYC 7B13 CPU 64 Core (OEM version of 7763) | eBay Now, the search term "7b13" only brings up a single hit on the entire forum and the contents of that thread seem to indicate that a 7b13...

I actually have never really gotten around to sorting out the licensing things, the 6012 is still sitting on my desk. Turns out that infiniband is doing everything I need at the moment, at least until >1gbit internet becomes available. I could, for downloading from steam up the size of my cable...

So far I haven't even got as far as actually going through the guide to turn this into a proper melanox switch. I am lacking motivation to go through it since the other infiniband switch I already have already does 98% of what I require of it. If I'm honest with myself I'll probably have to run...

For me staying within 1U wasn't neccesary, so this is how I solved it. 200mm hole in the top, cut a piece of plastic out of a folder to make an airguide which effectively blocks off the rear, air now blows onto the top of and under the pcb, and is vented out the front. These noctua fans are...

Thanks! I'll give that a go tomorrow. I was looking for a way to launch the wizard, so that should be exactly what I need.

Yours I think: https://docs.google.com/document/d/1SS0_70PSD5NZDxMy-B---4X1i_2WiLoe/edit Nothing happens when I follow those links... unless my pihole has decided that hpe is an ad site, it's a little mysterious...

Hey all, I purchased a SX6012 a while ago and have finally gotten around to messing with it. It looks like that despite my best efforts to get ahold of a true melanox one, it appears to be an EMC version. * Chasis Type : DINGO * Number of Ports : 12 * U-Boot Revision :U-Boot...

So, unfortunately, despite specifically looking for and finding a SX6012 with no trace of EMC markings anywhere on the box, it appears that this does in fact have a EMC uboot image... guess I'm off to find that thread about switching from EMC to regular MLNX-OS. * Chasis Type : DINGO *...

Not sure whether you were reacting to my project, and this is a little bit of a late reply, but I'm happy with the little infiniband network I'm running. I'm only using it as access to my network drives at the moment, but I am running games off of m.2's in my server which deliver data at around...

Thanks for the quick reply. It was doing this both with and without an address set on my ethernet port that's directly connected to the mellanox. MAC address is also the Mellanox's. Not fully understanding why it isn't receiving an adress when I connect it on my network. There must be some...

I've just finally sat down with this. I'm no expert on tcpdump, but I'm getting: IP 0.0.0.0.bootpc > It seems to be making mdns requests, probably looking for a network boot? Is anyone familiar with this behavious by any chance?

Never mind that last, some a bit of duckduckgo with the original fan number FFB0412UHN eventually turned up that it's a product from Delta in Thailand. For future reference: Red: +12V Black: GND Blue: RPM Yellow: PWM That allowed me to translate it to industry-standard 4 pin on the Noctua.

Finally cut a 200mm hole in the lid of my sx6012. Two things became clear. One, the lid functions as a bit of a heat sink for the psu's. I don't imagine this will be a problem with the fan directly above it, (unless those pads are purely for insulation) but I may need to turn the fan round so...

In the end I did figure out that the setting the fans to max thing had to do with the rpm range the ipmi expected to see. Obviously, the 200mm fan has rather low rpm's and the reaction of the ipmi was to set everything to max... sort of at some point when the rpm's were outside the expected...
