> The strange CPU core layout is causing power problems; Radxa and Minisforum both told me Cix is working on power draw, and enabling features like ASPM. It seems like for stability, and to keep memory access working core to core, with the big.medium.little CPU core layout, Cix wants to keep the chip powered up pretty high. 14 to 17 watts idle is beyond even modern Intel and AMD!

Sigh. It's always something...

Nice device but the experience write up is more about distro choices than anything. It's quieter than the older units and it's harder to run 2 disk ssd raid because of some design choices. Is it faster? How many virtuals? What's the throughput if you use it for complex network related roles not offloaded to the microtik switching/routing kit?

Does FreeBSD work better?

$599 seems like a lot to me. You can get numerous older, much more powerful Mini PCs (e.g older ThinkCentre Tiny series) or even a base brand new M4 Mac Mini for that kind of money.

Admittedly, the 10G interfaces and fast RAM make up for some of it, but at least for a normal homelab setup, I can't think of an application needing RAM faster than even DDR3, especially at this power level.

You can't get an ARM one though, only X86, which is mostly the point.

g947o 3 hours ago | parent | next [-]

Most people don't care about nominal difference in x86 vs arm. They care about cost, performance, efficiency, noise etc. Which applications run on the machine does matter.

The article never explained why the author wanted an ARM setup. I can only consider this a spiritual thing, just like how the author avoids Debian without providing any concrete explanations.

CharlesW 3 hours ago | parent [-]

The usual reason to prefer ARM is efficiency, and the author's mention of replacing "power-hungry HPE towers" seeems to support that as a primary motivating factor.

inventor7777 3 hours ago | parent [-]

True. But as detailed in the Jeff Geerling article that was shared here in the comments, it has (at least at the moment) a rather high idle power draw, which seems to negate that, especially over time.

inventor7777 3 hours ago | parent | prev [-]

True. However, I've always noticed that ARM has less Linux support than x86, and the main benefits ARM is known for are typically performance/watt, running cooler, and less legacy support.

Since this server seems to have pretty average performance/watt and cooling, I can't really see much advantage to ARM here, at least for typical server use cases.

Unless you're doing ARM development, but I feel like a Pi 4/5 is better for basic development.

Linux support for ARM is inferior for end users of desktop 3rd party software. Everything else is provided by the repos. I doubt this person runs Signal or Spotify on those servers.

For those who don't need quite that much power I recently added an Orange Pi 5 to my own homelab, the RK3588 SoC packs an impressive punch for what it is

nine_k 2 hours ago | parent | next [-]

Does it run a mainline Linux kernel?

ninth_ant 3 hours ago | parent | prev [-]

And despite their broadly similar performance, the RK3588s have significantly better power draw.

However I’m not sure of any of the rk3588 vendors that support both UEFI and have a full-size PCIe slot like the MS-R1 has.

Funny, I just bought one of these last week. Agree with the article. Mine came with storage and Debian preinstalled. If you buy one from Amazon, keep an eye on price. I bought, then the next day the price dropped $150. Ordered another one and returned the expensive order.

cweagans 5 hours ago | parent [-]

You used to be able to just call Amazon and they'd refund the difference. Not sure if they do that anymore.

jdpedrie 5 hours ago | parent [-]

They did not. The rep told me to return it and buy another. :/

And fuck the planet, your time and the time of the logistics people.

This is so incredibly inefficient. Multiply by how many times this happens every day...

It's efficient ... for amazon ... because most people won't bother.

> Yes, while I use Fedora on my laptop, I also know Fedora is generally not a good option for a server.

Why is Fedora not considered good for a server?

neelc 5 hours ago | parent | next [-]

It's a cutting-edge distro with 6-month release and 13-month support cycles.

Whereas Debian/Ubuntu have 5 years and RHEL/Alma/Rocky have 10 years.

zuntaruk 4 hours ago | parent [-]

I don't feel like this really answers the question thought, right? At least not at face value.

I could see the side of maintenance burden being a potential point, meaning that one would be "pushed" to update the system between releases more often than something else.

p_ing 3 hours ago | parent | next [-]

Typically you want stability and predictability in a server. A platform that has a long support lifecycle is often more attractive than one with a short lifecycle.

If you can stay on v12.x for 10 years versus having to upgrade yearly yo maintain support, that’s ideal. 12.x should always behave the same way with your app where-as every major version upgrade may have breaking changes.

Servers don’t need to change, typically. They’re not chasing those quick updates that we expect on desktops.

zuntaruk an hour ago | parent [-]

Yeah, and that's the take I assumed to hear based on what was said.

However, for something like ARM and the use case this particular device may have, in reality you would _want_ (my opinion) to be on a more rolling release distros to pick up the updates that make your system perform better.

I'd take a similar stance for devices that are built in a homelab for running LLMs.

g947o 3 hours ago | parent | prev [-]

I take it as no more than someone's personal opinion, since there is no reference provided whatsoever.

zuntaruk 5 hours ago | parent | prev [-]

I'd also love to hear what folks have to say about this.

For myself I've had nothing but positive experiences running Fedora on my servers.

Why is the power supply 2x larger than a Macbool Pro PS unit? Cheap? What about GaN?

neelc 6 hours ago | parent | next [-]

Mac Mini/Studio has an integrated power supply, but other Mini PCs do not have the same luxury. It doesn't matter if you're Minisforum or HP.

Minisforum probably reused the x86 power supply for ARM. The x86 MS-01 and MS-A2 supports GPUs after all.

I'm not a hardware engineer, I've failed miserably in software engineering and now run a VPS host.

metadat 6 hours ago | parent | next [-]

I was wondering why the PSU is half the size of the compute unit housing. 15 years ago, sure, but today it just seems cheap and lazy on part of whoever designed it.

Caveat: I'm frequently mistaken, always keen to learn and reduce the error between my perception and reality!

>I'm not a hardware engineer, I've failed miserably in software engineering and now run a VPS host.

I’m curious how hard hosting VPS as a business was to get off the ground? I’ve worked 5 years previously as a Linux sysadmin, but am getting pretty bored at my current job (administering Cisco VOIP systems). Think I’d rather go back to that

My Beelink Me Mini has an integrated PSU. Actually same with the EQR6 I got too.

zamadatix 3 hours ago | parent | prev [-]

I think that's why they were comparing to the MacBook Pro rather than the Mac Mini/Studio.

wmf 5 hours ago | parent | prev | next [-]

It's just cheap.

plagiarist 5 hours ago | parent | prev [-]

I have a personal ban on any hardware that isn't powered by USB-C. (Or if it's large I'll accept a C17 socket.) Either give me a GaN or I will get it myself.

Otherwise I'd probably have a few machines from this company.

zamadatix 3 hours ago | parent [-]

This model accepts 100W USB PD input as well.

koonweee 4 hours ago | parent | prev | next [-]

slight tangent, but anyone had experience with running asahi on a m2 MacBook headless? I have a m2 air with a damaged screen id like to repurpose. Mostly want docker containers or something coolify adjacent

hi_hi 4 hours ago | parent | prev | next [-]

Not sure I understand this distinction.

> I’ve always wanted an ARM server in my homelab. But earlier, I either had to use an underpowered ARM system, or use Asahi...

What is stopping you using Mac with MacOS?

tiew9Vii 4 hours ago | parent | next [-]

It’s not great as a headless server.

With full disk encryption enabled you need a keyboard and display attached at boot to unlock it. You then need to sign in to your account to start services. You can use an IP based KVM but that’s another thing to manage.

If you use Docker, it runs in a vm instead of native.

With a Linux based ARM box you can use full disk encryption, use drop bear to ssh in on boot to unlock disks, native docker, ability to run proxmox etc.

Mac minis/studio have potential to be great low powered home servers but Apple is not going down that route for consumers. I’d be curious if they are using their own silicon and own server oriented distro internally for some things.

azov 4 hours ago | parent | next [-]

They fixed unlock in the last release:

"On a Mac with Apple silicon with macOS 26 or later, FileVault can be unlocked over SSH after a restart if Remote Login is turned on and a network connection is available."

https://support.apple.com/guide/security/managing-filevault-...

hi_hi an hour ago | parent | prev | next [-]

Thanks for the reply. I'm looking to replace my aging mini pc with a mac mini, so I'm quite interested in any limitations here.

The full disk encryption I can live without. I'm assuming these limitations don't apply if it's disabled. [Ah, I just saw the other reply that this has now been fixed]

I was aware of the Docker in a VM issue. I haven't tested this out yet, but my expectation is this can be mitigated via https://github.com/apple/container ?

I appreciate any insights here.

unsnap_biceps 3 hours ago | parent | prev [-]

    The root of trust for Private Cloud Compute is our compute node: custom-built server hardware that brings the power and security of Apple silicon to the data center, with the same hardware security technologies used in iPhone, including the Secure Enclave and Secure Boot.
https://security.apple.com/blog/private-cloud-compute/

Granted, I don't know if it's really server oriented or if they're a bunch of iPhones on cards plugged into existing servers.

geerlingguy 4 hours ago | parent | prev [-]

Most likely wanting to run Linux natively. Only M1/M2 can fill that role with Asahi, and still not with 100% hardware compatibility.

On the flip side, an M4 mini is cheaper, faster, much smaller (with built in power supply) and much more efficient. Plus for most applications, they can run in a Linux container just as well.

hi_hi an hour ago | parent [-]

Thanks for the reply Jeff. This aligns with my understanding too. I'm close to purchasing a mac mini to replace my aging media pc. The core feature I want is to run microK8s natively, which I'm assuming the newish Mac containers will support.

> There is also one other perk: while the MSRP is $599, I got it for $559 despite a RAM shortage.

At that price, why not a mac mini running linux? I think (skimming Asahi docs) the only things that would give you trouble don't matter to the headless usecase here?
