I know port multipliers are bad, and all that, but dang these things are getting interesting https://www.amazon.com/Port-Non-RAID-SATA-Adapter-bandwith/dp/B0BGJPDL8N/ [IMG_0970] [IMG_0973]

Allow me to jump in here. We can certainly encourage/discourage certain component choices, but ultimately each user is responsible for their own decisions, their own level of acceptable risk tolerance, and their desired system form factor/budget. It’s important to note that M.2 is only a form fact…

[image] Stux: What’s the ASMedia controller used in some MiniXLs from IX? IIRC, those were Marvell. And one of them needed a special firmware update that was unobtainium other than through iX. And it still caused trouble occasionally.

[image] ericloewe: problem in any way, nor is it a driver problem. Or an OS problem more broadly. It is 100% a problem of crap hardware that is explicitly not supported by Intel (and if you dig it up, I bet AMD’s chipsets don’t either). That leaves the likes of Marvell and ASMedia, who struggle …

I didn’t expect the first entry on my ignore list here would happen so soon. Ah well.

[image] William_Steele: SATA port multipliers go back over two decades and allowed many more hard drives to be connected to a sata controller when putting that many sata controllers in a server just wasn’t possible. Name a single serious server that uses a SATA port multiplier. I will not hol…

For those with an ASM1166 based controller, may want to delay upgrading to Dragonfish [image] After upgrade to 24.04, 4 (out of 13) of my disks no longer show up TrueNAS General Sure, that is definitely possible, although it worked fine in Bluefin and Cobia, and is curren…

[image] Stux: ASM1166 Not entirely clear to me if it’s a controller issue or if there’s a port multiplier in the mix. I think some folks are starting to see port multipliers where there only crappy AHCI controllers, which makes things hard to follow…

I am the author of the post @Stux referenced above (although now I’ve seen others reporting the same issue), and in my case the product is the “MZHOU PCIe SATA Card 8-port” (link) which I’ve come to understand (mainly from this blog post ) is based on the ASM1166 SATA controller, which is a cheap SAT…

@axhxrx thankyou for the candid reply I’m not trying to disparage people’s hardware, but rather work out what works and what doesn’t. Unfortunately there are very good reasons why Port Multipliers are a bad idea, what I’m not so convinced about is that all SATA controllers are inherrently flawed. A…

Sure. To be clear, I didn’t find your comments snarky at all, I was more referring to the memes like this . (But even those kinds of things are actually pretty helpful to help figure out Hmm should I allocate time to understanding this better?)

[image] William_Steele: Everyone on here complaining that people are trying different inexspensive solutions is hilarious. The point is that none is playing around but truly using those adapters: one thing is saying “everyone, here Is this new thing I will test and come back to you” another i…
