It's a 4-way M.2 NVMe raid card, which HP has ignorantly decided to populate with seemingly mediocre SSDs instead of the current gen flagships from Samsung or Intel. You can remove the included SSDs and populate it with up to 4 960 Pro SSDs for what I imagine would be 14/8 GB/s sequential read/write performance. Unfortunately there's no way to buy it without the included SSDs, so you're better off with the unpopulate…

> Unfortunately there's no way to buy it without the included SSDs Ah, brings back memories of buying HP servers several years ago. The only way to get the servers we needed was to buy servers pre-shipped with inadequate RAM and drives, rip it all out, and then install new drives and new RAM (purchased at the same time from HP, for an inflated price of course). We were left with a pile of essentially useless SAS driv…

Why was hp hardware a requirement? What was so special about hp hardware?

I don't understand why they didn't use a Xeon e3-1545m, which is a 35-45 TDP part and has adequate graphics for the intended market. If it doesn't support ECC, there's no benefit vs the Intel Skull Canyon. I am in the market for a new dev machine, and I want Xeon and ECC. Just not enough good options currently (unless you build from scratch).

It does support ECC, but I don't understand its thermal design. Probably it's like NUCs, a small box for the sake of prettiness and a tiny-n-cheap fan that will be noisy. It's a shame, because you can passively cool things like a i7-6700T these days without much effort and without ever falling into throttling [1]. Plus, Calyos is about to release a loop heat pipe that will be able to cool massive systems without any…

Just interested: What's your use case for ECC? Do you intend to run a server on it and aim for highest stability?

On my current desktop machine (32GB ECC DRAM) I see a single bit error (corrected) probably every 18 to 20 days. There isn't an easy way to tell where that error hit in memory (you could presumably walk it back from the physical chip to the physical address space to the current page table and then back into virtual space and a process but that is waaaaaaaay too much work :-) Without ECC those errors would happen and…

How are you able to "see" the single bit errors? I had an ECC machine but I couldn't find any indication that ECC was working or that any bit errors happened.

Reading this I thought the best I could do is to believe that workstation with ECC modules and Xeon will have functioning ECC:

"Unfortunately, we have found that there is no consistent, conclusive way to determine if ECC RAM is working properly. ...We've actually asked Intel, Kingston and Asus over the years for their recommendations for methods to confirm that ECC is working, but we haven't gotten much more back than a blank stare."

I am hungry for news of HP's "The Machine" or whatever they're calling it, which is the big iron that will leverage and be built around the memristor-based memory. Any progress on that development?

They dropped the memristors from it last year: https://www.engadget.com/2015/06/05/hp-the-machine-no-memris...

I'm putting money on something to do with ZFS. Turns out bit flips are significantly more common than had been thought in the past, which makes a error-correcting file system somewhat risky to use with normal non-ecc ram.

But if you use ZFS, chances are you will want to have lots of disk space and lots of disks, too. If so, why buy a small box?

By pre-defining specs for the device, you can obviously create a sleak box for it with no wasted space, but I would claim it will always be impossible to create something as powerful as something 4 times its size, given the larger components are still produced, just going off physics. Otherwise no one would still build towers and just use laptops. (Of course more people use laptops, but it's not because of performanc…

Off the shelf parts with the Thin-ITX form factor can help you build a pretty powerful workstation at this size. I built one myself:

http://penguindreams.org/blog/building-a-thin-itx-router/

You wouldn't be able to build anything as powerful as these HP offerings, because they can custom fab parts to pack in ram and high end processors in a smaller density (like laptops) and build a lot of custom heat dispensations components as well.

Still, there are Thin-ITX boards that can support a decent amount of ram and power, just not Xeons or high end video cards.

it was a hype machine. the leader of HP labs just kind of made up a machine that combined all the experimental technologies the labs were working on (terrible idea: make a product that requires N experimental projects to all work out).

They specifically mention acoustics in the (long) text about it. I would assume that means they tried to make it quiet. Whether I believe them or not is up in the air, as my last HP workstation was louder than hell.

Is hell particularly loud? I've never been there.

What shitty vendor is this? Our VAR handles all of that for us. 48 Dimms, 16 SAS drives, P420e, and loads of nics. And they did the firmware updates and checked for defects.

The only thing I needed to do was rack it and kick off the PXE install.
