  1. Weird. #Supermicro has (had?) two different power distribution backplanes (for redundant hot-swap power supplies) for their SC825 series of 2U rackmount server cases: PDB-PT825-8820 and PDB-PT825-8824. The only difference appears to be that the -8824 has longer leads. The -8820's shorter cables won't reach the 12V CPU-power sockets on most mainboards, so I'm not sure how they could be used, and the -8824 seems to be discontinued. My -8824 broke and the replacement I received is a -8820. I have a spare for now, but would like to have one in stock, too.

  2. Sieben Einstellungen, kein Setup-Besuch: die BIOS-Konfiguration meines Supermicro-Boards ändern

    Im letzten Beitrag habe ich die BIOS-Konfiguration meines Boards als XML-Datei ausgelesen. Lesen ist die eine Hälfte. Diesmal schreibe ich zurück: sieben Einstellungen, ohne den Rechner auch nur einmal ins Setup zu booten. Warum ich genau diese sieben genommen habe, welche vier ich bewusst in Ruhe gelassen habe, drei Fallstricke, die mich Zeit gekostet haben, und die Frage, ob es dafür nicht einfach eine grafische Oberfläche gibt.

  3. Achtundzwanzig Euro für eine Textdatei: die BIOS-Konfiguration meines Supermicro-Boards auslesen

    Mein Serverboard hat 372 Einstellungen im Setup. Ich wollte sie als Datei haben, nicht als Fotoserie. Drei Wege dorthin waren verschlossen, alle drei mit derselben Begründung. Diese Begründung nannte den Preis, und der lag bei 28,17 Euro. Was ich dafür bekommen habe, was weiterhin gesperrt bleibt, und warum ich vorher eine falsche Schlussfolgerung gezogen hatte.

  4. For the first time I had to replace a hot-pluggable power supply. The constant 1000-Hz-beeping was really annoying. Replacing it was a total non-event. Pulled the power cord, removed the old PSU, (beeping stops), insert the new one (beeping resumes), plug in the power cord, beeping stops. Done.

  5. Ich erwäge, den Server nachts abzuschalten und morgens zu starten. Leider gibt es bislang Probleme beim Reboot, wenn das System ein paar Tage gelaufen ist. Ganz zu schweigen davon, dass ich wohl #Podman Quadlets meistern und die automatisierte LUKS-Entschlüsselung sauber hinbekommen müsste. Aber eins nach dem anderen...

    Also versuche ich, ob ein UEFI-Upgrade hilft. Also zuerst mal #BMC für #IPMI konfiguriert und darüber das Upgrade gemacht. So weit, so gut. ✅

    Hab jetzt rausgefunden, dass man das Upgrade von #UEFI bei #SuperMicro wohl am Besten via Webinterface aktualisiert. Jetzt scheitere ich daran, dass ein Product Key verlangt wird. Erst mal schauen, wo ich den wieder her bekomme.

    Und was habt Ihr heute so gemacht?

  6. Taiwan government agencies raided the offices of Super Micro Computer and several of its local affiliates, deepening an investigation into Nvidia chips allegedly being smuggled into China using the company's servers. japantimes.co.jp/business/2026 #business #supermicro #china #nvidia #taiwan #china #semiconductors #chipmakers

  7. ARM-серверы от Supermicro для агентов ИИ — почему это интересно

    На выставке Computex 2026 компания Supermicro ® представила новую линейку серверов для агентного ИИ, облачных сервисов, HPC и масштабируемых вычислительных кластеров. В сердце платформ — процессоры Arm AGI на архитектуре Arm Neoverse CSS V3. В максимальной конфигурации один процессор содержит 136 ядер, что дает в двухсокетной системе до 272 ядер. Все платформы поддерживают DDR5 и современные интерфейсы вплоть до PCIe 6.0.

  8. It is really petty and ridiculous that on H12 platforms #SuperMicro no longer allows virtual media from the console.

    To install a system you need a license¹ unless you go and stick a USB stick in it.

    I find it ridiculous that you pay for a stupid PC *server*² and then need to stick a USB in it to be able to install… where do they think you install servers? They know full well that you will need to get either remote hands or pay for a license. What else could you possibly want IPMI for?

    __
    ¹ on H12 you cannot use the various tools to generate a license as the license file JSON is now digitally signed by SuperMicro…
    ² stupid because PC servers are not really servers, just headless PCs with all that goes with it. I hate PC design, crap from a IBM cheap thing still with us.

  9. > BIOS can't pass the secure validation.

    #SuperMicro great, they of course had to implement a bios validation to prevent me from just patching in the ReBAR support...

    So where is my in-circuit flasher? And where is the bios chip on the H11DSi?

  10. I wanted to add a button to Home Assistant that would turn on my remote server via IPMI. I also did not want to add the ipmitool dependencies to my #HASS container. Since IPMI supports redfish, a simple rest command in home assistant is enough. Add this to your `configuration.yaml`:

    ```yaml
    rest_command:
    # Command to turn the server ON
    server_power_on:
    url: "https://192.168.100.111/redfish/v1/Systems/1/Actions/ComputerSystem.Reset"
    method: post
    username: "hass"
    password: "eX4mP13p455w0Rd"
    verify_ssl: false
    headers:
    Content-Type: "application/json"
    payload: '{"ResetType": "On"}'

    # Command to gracefully shut down the OS via IPMI (ACPI signal)
    server_power_off:
    url: "https://192.168.100.111/redfish/v1/Systems/1/Actions/ComputerSystem.Reset"
    method: post
    username: "hass"
    password: "eX4mP13p455w0Rd"
    verify_ssl: false
    headers:
    Content-Type: "application/json"
    payload: '{"ResetType": "GracefulShutdown"}'

    sensor:
    - platform: rest
    name: "Server Power State"
    resource: "https://192.168.100.111/redfish/v1/Systems/1"
    method: GET
    username: "hass"
    password: "eX4mP13p455w0Rd"
    verify_ssl: false
    scan_interval: 10 # Checks every 10 seconds
    value_template: "{{ value_json.PowerState }}"

    template:
    - switch:
    - name: "Server"
    state: "{{ is_state('sensor.server_power_state', 'On') }}"
    icon: >-
    {% if is_state('sensor.server_power_state', 'On') %}
    mdi:server-network
    {% else %}
    mdi:server-network-off
    {% endif %}
    turn_on:
    action: rest_command.server_power_on
    turn_off:
    action: rest_command.server_power_off

    ```

    Make sure to create a separate IPMI user with "Operator" privileges (allowed to start/shutdown, but not to modify settings). If you have e.g. #Proxmox on the server, it will receive the IPMI Graceful Shutdown command and cleanly stop all VMs before exiting.

    Works great!

  11. Oh great, I cannot execute their "saa" support tool because of #NixOS "things"...

    Could not start dynamically linked executable: ./saa
    NixOS cannot run dynamically linked executables intended for generic
    linux environments out of the box. For more information, see:

  12. I wrote an email to the #Supermicro support asking if it would be possible to get resizable BAR support for the H11DSi motherboard as that appears to be the only way to actually fix this hardware issue here at its root.

  14. Jak ominąć ograniczenia eksportowe GPU w USA i przemycić sprzęt za blisko 2,5 mld dolarów? Wiceszef zarządu Supermicro wiedział to najlepiej

    Wraz z wprowadzeniem restrykcji dotyczących eksportu procesorów graficznych (GPU) – zapoczątkowanych przez USA w 2022 rok i drastycznie zaostrzonych rok później – układy takie jak NVIDIA H100 i H200 stały się towarem deficytowym. Dla większości krajów zostały wprowadzone limity ilościowe, nakładające maksymalna liczbę sztuk, którą dany region może zaimportować w...
