    Broadcom Tries To Kill InfiniBand

    I double checked, ChatGPT was wrong, it only mentioned NVMe-oF using TCP. According to the Intel Documentation Omni-Path does indeed use RDMA for NVMe-oF. That makes it really interesting, as Omni-Path is very cheap.

    But Omni-path doesnt have anything like SRP or NVMe-oF over RDMA

    EXPIRED Ebay - SK Hynix 32GB DDR4-2933 RDIMM 17,5 euros

    This was a insane deal. DDR4 Memory prices has increased almost 100% last 2 months. I would have bought em all if I got the chance, I do not expect prices to drop much, so even If dont have a use for them today, this was a deal that would still be great next year too. There is an insane global...

    Broadcom Tries To Kill InfiniBand

    I didn't try Infiniband until last year. I always thought I was complicated and I needed to spend a few days to understand it. But as I wasted significant of time trying to get RoCE to work "reliable" on my ConnectX3 cards, I figured I should try Infiniband. Oh boy, I didnt spend many minutes to...

    Slow? These do 5GB/s for reads, 500k iops, and they have great endurance with 5 DWPD. They have 2 big drawbacks, and that is they get hot because of high power consumption and lack of support for namespaces.

    I have 2 different firmwares for this. IR3Q and YR3Q. Every version I've bought of the Oracle f320, has either of them. I have never updated the firmware because of this. The drives has been great, except from the heat.

    Need you Opinion on a SC846

    Almalinux 10 has a v2 release. Almalinux 10 also supports older hardware, like SAS2008 or Mellanox ConnectX 2

    Need you Opinion on a SC846

    While x9 is old and slow, I think they still have some value. But, it really depends. I still have a few left in production. I find them useful for ZFS and storage stuff(many pci lanes is great), zookeeper nodes, and other tasks that doesnt require fast cpu. Single thread performance is only...

    Celestica Seastone DX010 32Port 100G QSFP28 $250

    Many L3 switches has access control, which is kind of a firewall.

    Celestica Seastone DX010 32Port 100G QSFP28 $250

    SONIC is maybe Debian under the hood. But you will quickly see how britle and fragile it is. As L2 switch it is ok, L3 can be hit and miss. I seems that OpenWRT works on Spectrum switches [OpenWrt Wiki] Mellanox Spectrum Switches but, you will lose important fucntionality. For example enabling...

    Celestica Seastone DX010 32Port 100G QSFP28 $250

    Yeah, that makes it a very interesting switch for that price. Power consumption is still high for homelab though.
