Supermicro boards - why do they POST so slowly?

    Normally not much of an issue, but I had a massive headache last night where I kept having to restart into DOS, UEFI shell, Linux, over and over.

    Why the heck do these boards take so long to POST? Is there any setting I'm missing that will speed things up?

    The delay is mostly due IPMI.
    You can disable IPMI to speed up boot but mostly you want IPMI on a server board.

    IPMI like Gea said as well as other controllers(raid controllers have their own bios to load) and network cards checking for things like PXE as well.

    Got to be the IPMI. All oproms are disabled so no raid controller bioses or pxe. Not willing to give that up, since the system is completely headless and I was doing all that over IPMI.

    I've also found boards with onboard SAS controllers to boot up much slower as well. My M11SDV board boots up 10x faster than my X10SDV board that has an LSI 2116 onboard.

    Intel's MBs aren't different .
    Have few SM and Intel boards - roughly equal boot times. Yes, it's irritating , especially when you're on hurry :)

    Any server board really compared to consumer ones really, remember the ipmi is literally a second computer and most of your controllers are far more capable than their consumer equivalents and have their own initialization times as well.

    Eh, ever boot up a PowerEdge R620 with the baseband controller/DRAC and RAID controllers active? It's just as bad, if not worse.
    The more hardware features you have attached to your machine, the longer it'll take for the hardware to run through its startup diagnostics.

    IIRC some of the ASRock server boards have a "wait for BMC" toggle in the BIOS that allows you to skip waiting for the IPMI to come up before you can boot, but I don't think I've seen this on any SM boards.

    90 seconds is nothing, I used to work with some IBM servers that took over 15mins to POST.

    like others have said already, i don't know of many actual server grade systems that have really fast POST times. Not supermicro, not Dell, not IBM, not Intel, ... don't know about recent HPE, but they took while when I worked on Compaq servers. these days, i always disable memory test during POST to speed it up.

    question is then:

    1) are there any server grade systems that have really fast POST times? (relative to all the above mentioned brands of servers)

    2) what are some tips you guys have to speed up POST?

    Supermicro is just what I've had most experience with, not to pick on them. My Intel board that I couldn't get to work with a QS CPU seemed to be a little faster (with a temp CPU) but not by much.

    Not much I've found to speed things up. Disabling all oproms and unused onboard devices helps, but it's still slow.

    You would think there'd be some demand for super fast boot times for minimum downtime when you have to update. It takes this server longer to POST than it does to load Windows and restore 20 VMs off NVMe storage. I'd certainly love to see a "fast boot" option added like on consumer systems. Just initialize the absolute minimum and let the OS take care of the rest.
