Obsurveyor posted:ECC required for ZFS smells like bullshit and cargo cult behavior to me. The key phrase being "any moreso than any other filesystem". If your data is significant and irreplaceable, or business-critical, or legally significant, then you should use ECC on any filesystem. If a bit gets flipped in your animes... so what? Google's done some large-scale research here and bit errors are actually quite common. They scale up significantly with altitude, they scale up significantly with memory allocation amounts and CPU utilization, and of course temperatures are also well-known to scale up the error rate as well (hairdryers are a common method to induce bit errors). They also tend to increase significantly on older harder that's been used for more than ~20 months. About one third of machines in Google's study experienced at least one memory error per year, with some platforms as high as 50% per year. Machines that have errors tend to have lots of them, with the median number of errors per year for machines having at least one error ranging from 25 to 611 (again depending on platform). So basically the distribution here is kinda bimodal, most machines don't experience any failures but the ones that do really poo poo the bed like crazy, and those are often older machines and ones under high load. Of course, without ECC you don't really know whether your hardware is perfect or the silicon equivalent of Tubgirl. Paul MaudDib fucked around with this message at 06:04 on May 6, 2017 |

Obsurveyor posted:ECC required for ZFS smells like bullshit and cargo cult behavior to me. The key phrase here is "any more so than any other filesystem", meaning "ECC should not be a factor in deciding between a filesystem and ZFS". Because if it meant something to you, you'd be using ECC, whether you were on ZFS, Btrfs, EXT4, or whatever. e;fb

I still can't get over the idea that otherwise intelligent people don't stop at the 1 gb ram per 2 tb storage (the recommended amount I've seen) and think, "Hmm, I feel like this need has more to do with the nature of my workload than the filesystem itself." :smithreddit:

I think the 2GB / 1 TB comes from people talking about enabling DEDUP on large arrays. You can just as easily offload that to a SSD cache

Am I crazy for thinking the Ryzen 5 1600 would be a decent option for a non-gaming home workstation? Paired with an efficient 4GB GPU, and 16GB of system RAM.

Potato Salad posted:Why ecc ram on a workstation? Yeah, I think blowfish may have some very specific workstation purposes in mind. My post and intention aren't including ECC. This is for a home base productivity setup (the sole desktop in the house) and the crazy core/thread count appeals to me.

I think that usually the idea is that whatever you're doing on a "workstation" is important enough that your output shouldn't be subject to soft errors that might not be detected. This is because to some people the term carries the connotation of doing protein folding or CAD or video editing or some such important poo poo, IDK. Your particular circumstances will of course affect your chance of soft errors happening at all, changing something important and/or going unnoticed.

With Ryzen where in theory ECC is supported by every CPU / MB, why the hell not? ECC is like a $15 premium then.

sweart gliwere posted:If it's that small a difference, it's worth it I guess. The premium on ECC memory itself is usually pretty minimal, the problem is that Intel has forbidden i5/i7 CPUs from using ECC, as well as the cheap consumer H and Z motherboards.

Why *not* ECC in every device? It *should* be a security thing, but alas, speed is king, and cutting costs is the advisor manipulating the king like a puppet. http://www.techspot.com/article/845...-vs-ecc-memory/ (I don't know of any similar tests with DDR4.)

ECC for fun and security should totally be a thing! I'm not a stakeholder in AMD or Intel, though, so I'm resigned to pointing out that a $15-20 increase (if it is indeed that low) on ecc ram may or may not do as much net good as a spontaneous bouquet of flowers for your mother or spouse, depending on whether its just a home pc for browsing or a true critical-workload workstation.

Is ECC 3200 MHz DDR4 even available? Anything slower on Ryzen seems sub-optimal.

My vote's for AMD. They are like a dumb puppy. Overeager and even sometimes occasionally useful. Nvidia's wants to push SaaS onto you, and SaaS is a legitimate goddamn cancer. SwissArmyDruid fucked around with this message at 07:24 on May 11, 2017 |

16C/32T sounds nice if you have the right use case. Do you guys expect this to have higher IPC than current Ryzen as comes with Quadchannel DDR4, stupid amounts of cache and perhaps a few architectural "hotfixes"?

Unless it clocks higher its going to be no better if not worse for gaming because it cant clock as high as the 8 core chips

If you're actually doing something using all those threads then 4 channel memory is a must. For games and other stuff 16 threads or less I wouldn't expect to see much if any difference with one of those at all vs a similarly clocked 8C16T Ryzen. A 64 MB L3 could make a nice difference for somethings like Crystalwell did though. There has been no real word on what effect any of the minor fixes that were hinted at are going to have. I wouldn't expect much there. Probably just some bug fixes and little to nothing to do with performance. Platform wise if you really need lots of PCIe then you've got something to look for I guess. I'd care more about the integrated 10Gbe ports myself. The block diagram seems to show them integrated into the CPU itself which is a bit odd, should be pretty fast and power efficient as a result of that.
