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...

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've spotted this Epyc Milan in local pricing lists and I'm wondering what's up with it? It has a strange number of cores (4x7C enabled?) and not a hell of a lot of cache, but it's priced almost the same as a 7443P, though it has rather lower clocks. Does anyone have any experience with these...

I've recently set up a 40Gb SAN at home as Covid keep oneself occupied therapy, but I've come to the conclusion that I als want to run parallel 40GBE. I have Mellanox MCX354A-QCBT cards which I'll flash to FCBT, ideally using one port for the SAN and the other for 40Gbe. I have a mellanox IS5022...

I have an infiniband network providing a SAN to my workstation, debian 10 server (runs opensm), ubuntu 20.04 workstation. Without a partitions.conf file, everything works, ipoib pings fine, except that ibdiagnet gives an error message that the group speed is only 10Gb, while node speed is 40Gb...

Hey all, I've been slowly working on a sort of covid-keep-oneself occupoed setup for my home network for a while, of which the scope eventually crept to a 40gbit infiniband network, which is working, in any case for what I originally intended, which is faster storage, both smb and nfs-rdma...

Hey All, Here's hoping I'm posting this in the right place, but as pfsense is freebsd based, I felt this was the closest category. As a keep-oneself-occupied through covid project I've been fiddling with my local network. All was originally instigated by annoyance with 1gbE transfer speeds and...

As posted in the title I'm looking for gear to convert my home network to 40gbit. Main purpose is sharing storage over rdma, my internet connection is only 100mbit, so ipoib seems like it would be fine for that. Even the second line I'm considering would keep the combined bandwidth at max...

Hey all, I have been considering getting some EOL qfsp+ gear as my current 1gbe solution annoys me when copying large files around my home network. In the course of my investigations I was wondering whether anyone regularly games over nfs/rdma in a satisfactory way? As is customary for me, my...

Hey all, I'm considering ubgrading to 10Gbe at home. The CRS-312 seems to be the only option that is reasonably priced and has the ports I'd want. The reports on the noise it (sometimes) makes make me apprehensive though. I read somewhere someone put in noctua fans, but that they weren't always...
