Came to post the same. Seems like the most awkward possible way to phrase that.
Your “Disks not included” suggestion, or heck, just “empty” would surely be better.

Interestingly, looking at Gentoo’s package, they have both the github and tukaani.org URLs listed:
https://github.com/gentoo/gentoo/blob/master/app-arch/xz-utils/xz-utils-5.6.1.ebuild#L28
From what I understand, those wouldn’t be the same tarball, and might have thrown an error.
2·10 months agoI’d be curious to see how much cooling a SAS HBA would get in there. Looking at Broadcom’s 8 external port offerings, the 9300-8e reports 14.5W typical power consumption, 9400-8e 9.5W, and 9500-8e only 6.1W. If you were considering one of these, definitely seems it’d be worth dropping the money on the newest model of HBA.
I’m definitely curious, would only personally need it to be NAS + Plex server for which either of the CPUs they’re offering is a bit overkill, but it’s nice that it fits a decent amount of RAM, and you’re not forced to choose between adding storage or networking.
Single-sided drives can be up to 4TB though, no?
Yes and no.
The original 2015 release (10240) has support from 2015 - 2025. The latest 2021 release (19044) 2021 - 2032.
The product as a whole has around 16.5 years of support from go to woah, but each individual release is supported for 10 - 11.
Free for personal use, so yes-ish. That’ll certainly be a deal-breaker for some.
Realistically, people who are using it for personal use would probably be upgrading to the next LTS shortly after it’s released (or in Ubuntu fashion, once the xxxx.yy.1 release is out). People who don’t qualify to be using it for free anyway are more likely to be the ones keeping the same version for >5 years.
To note: this appears to be a move from 5 years (standard, free) + 5 years (extended, paid) to 5+7. Users not paying Canonical aren’t getting anything different as to with prior LTS releases.
Standard free support for 24.04 is still 2024-04 through 2029-06.
3·10 months agoThere definitely are vendors ignoring common sense and putting socket SP5 on desktop boards.
No argument about the price, I think list on these is something like $13k USD.
Their top-of-the-range Epyc 9684X has 1152MB :)
See, and raise KDE Neon.
Ubuntu LTS base, but with up-to-date upstream KDE releases rather than the (typically) relatively ancient releases that Kubuntu has.
Really is the best of both worlds.
Specs look good for the price, and those machine work great with Linux (I’m using Ubuntu 22.04 on the slightly earlier 9310 right now).
The only slight downside of the 9315 is that the SSD is soldered to the motherboard. Make sure you back up your data regularly, because there might be no way to get anything off the machine if it breaks.
There’s also something of a lack of IO; just one USB-C on each side (which is nice, because you can plug the charger into either side). But I have no issues with Bluetooth headphones, and monitors with USB-C have always worked great for plugging larger numbers of peripherals in.
To expand on @doeknius_gloek’s comment, those categories usually directly correlate to a range of DWPD (endurance) figures. I’m most familiar with buying servers from Dell, but other brands are pretty similar.
Usually, the split is something like this:
- Read-intensive (RI): 0.8 - 1.2 DWPD (commonly used for file servers and the likes, where data is relatively static)
- Mixed-use (MU): 3 - 5 DWPD (normal for databases or cache servers, where data is changing relatively frequently)
- Write-intensive (WI): ≥10 DPWD (for massive databases, heavily-used write cache devices like ZFS ZIL/SLOG devices, that sort of thing)
(Consumer SSDs frequently have endurances only in the 0.1 - 0.3 DWPD range for comparison, and I’ve seen as low as 0.05)
You’ll also find these tiers roughly line up with the SSDs that expose different capacities while having the same amount of flash inside; where a consumer drive would be 512GB, an enterprise RI would be 480GB, and a MU/WI only 400GB. Similarly 1TB/960GB/800GB, 2TB/1.92TB/1.6TB, etc.
If you only get a TBW figure, just divide by the capacity and the length of the warranty. For instance a 1.92TB 1DWPD with 5y warranty might list 3.5PBW.
7·1 year agoThis video about ex-Soviet RTGs of questionable radioactive source choice is quite a good watch
https://www.youtube.com/watch?v=NT8-b5YEyjo
NASA apparently used RTGs for deep space missions only, while in the same timeframe the Soviets scattered them all across the countryside, then promptly forgot about them.
Heh, came here to post that and you beat me to it by 40 minutes.
Other user’s comment up thread about “churning vomit water”… accurate.

303·1 year agoNot OP, but genuine answer: because I loathe being forced into their way of doing things. Every little thing on the Mac seems engineered with an “our way or the highway” mentality, that leaves no room for other (frequently, better) ways of achieving anything.
Adding to that, window/task management is an absolute nightmare (things that have worked certain ways basically since System 6 on monochrome Mac Classic machines, and haven’t improved), and despite all claims to the contrary, its BSD-based underpinnings are just different enough to Linux’s GNU toolset to make supposed compatibility (or the purported “develop on Mac, deploy on Linux” workflow) a gross misadventure.
I just find the experience frustrating, unpleasant, and always walk away from a Mac feeling irritated.
(For context: > 20 year exclusively Linux user. While it’s definitely not always been a smooth ride, I seldom feel like I’m fighting against the computer to get it to do what I want, which is distinctly not my experience with Apple products)
Probably best to look at it as a competitor to a Xeon D system, rather than any full-size server.
We use a few of the Dell XR4000 at work (https://www.dell.com/en-us/shop/ipovw/poweredge-xr4510c), as they’re small, low power, and able to be mounted in a 2-post comms rack.
Our CPU of choice there is the Xeon D-2776NT (https://www.intel.com/content/www/us/en/products/sku/226239/intel-xeon-d2776nt-processor-25m-cache-up-to-3-20-ghz/specifications.html), which features 16 cores @ 2.1GHz, 32 PCIe 4.0 lanes, and is rated 117W.
The ostensibly top of this range 4584PX, also with 16 cores but at double the clock speed, 28 PCIe 5.0 lanes, and 120W seems like it would be a perfectly fine drop-in replacement for that.
(I will note there is one significant difference that the Xeon does come with a built-in NIC; in this case the 4-port 25Gb “E823-C”, saving you space and PCIe lanes in your system)
As more PCIe 5.0 expansion options land, I’d expect the need for large quantities of PCIe to diminish somewhat. A 100Gb NIC would only require a x4 port, and even a x8 HBA could push more than 15GB/s. Indeed, if you compare the total possible PCIe throughput of those CPUs, 32x 4.0 is ~63GB/s, while 28x 5.0 gets you ~110GB/s.
Unfortunately, we’re now at the mercy of what server designs these wind up in. I have to say though, I fully expect it is going to be smaller designs marketed as “edge” compute, like that Dell system.
