Do we have any timeline for Denverton boards actually purchaseable? I don't really need the beef / price of a Xeon-D board except maybe a 2 core, but low TDP and good connectivity is appealing.

How strong is the suggestion that you shouldn't use ext4 on volumes larger than 16TB? I can't tell if it's just a minor performance thing, or if I should not even consider ext4 on large volumes and look at xfs instead.

DrDork posted:Same with the other NAS drives--most of them are 5400/5900 RPM and tuned for low power use. If the drives you already have are 5400's, though, it probably won't be a night and day difference and you should look at trying to improve airflow. Admittedly, there have been a few reports out that suggest that moderately high temperatures like 50C aren't actually all that bad for drives, but YMMV. Toshiba and Seagate didn't get the memo, most of their new line of NAS drives are 7200 RPM. Worst of all, on the Seagate Ironwolf basically no specs are constant across the line.

I disagree with this take. Used enterprise SSDs are sure a good deal, but current DDR4 and Flash prices are not permanent and they will continue to fall in the long run once fabs have finished retooling for newer processes and are able to catch up some with pent-up demand. Optane is new, expensive, and not mainstream yet. I'm cautiously optimistic about it.

If there's no need for HA and storage needs are about 100TB, there is absolutely zero reason to look at something like Ceph instead of just a 12+ drive ZFS (or mdadm) box, right? It looks like you have to throw absolutely huge amounts of resources at Ceph before it begins to approach the performance of a pretty simple zfs setup.

Zorak of Michigan posted:12 drives would be awfully small for Ceph, but I'd want to hear more about your environment to make a solid recommendation about what you ought to do. I want to try Ceph at home one way or another, and am considering recommending it to a group I work with. An academic lab that I consult with (not as IT, but writing software for them) currently has 1 storage box with 12x10TB hard drives in RAID 6 on an LSI raid card. Write performance is really lovely on it, which makes me think that the RAID card is likely the bottleneck and mdadm or zfs might actually be faster, given that it's got a lot of CPU power. They need another 100TB of storage soon-ish, and their IT guy mentioned that he wants to look at other options than just using a RAID card. They don't need HA, and don't need the storage to appear to be in a unified pool. What I'm getting at is for the same money, Ceph is just going to be way slower than their current solution, right? I (and their IT guy) are also curious if zfs on linux on the new storage server would outperform the 12-drive wide RAID 6 on a MegaRAID card, in which case they could move everything over to the new box, and re-do the original box's raid as software instead of hardware. I also don't know a ton about Ceph and maybe I'm misunderstanding and it can be cost and performance competitive with linux software raid at the 100TB - 200TB space.

Careful Drums posted:has anyone here set up a NAS w/ a raspberry pi and some USB hard drives? There's a lot of guides to them but I'm wondering about performance. Could I, say, rip a bunch of blu-rays/dvds onto it and stream them to my TV or would I need something beefier to handle that? It'll work fine as a toy, but terribly as an actual NAS solution. I'd buy a cheap commercial NAS if you don't want to tinker, or look at more conventional ZFS or mdadm linux NAS solutions if you want to fiddle and learn. Raspberry Pis have terrible network performance and won't even saturate their 100mbit ethernet interface. Loading stuff onto and off of them is a bad time, and if you have things like logs writing to the SD card eventually you'll wear out the SD card and have to replace it.

If you are willing to splash out $800 for a mobo+CPU, it's arguably a better buy than anything you can do on the LGA1151 platform, and it's way more power efficient than an X99/X299 platform. I hear this, but I can't help but feel that a $180 6-core i5, reasonable motherboard, and simple HBA in IT mode is still far better bang for the buck. Just like the Xeon-D platforms I think that for home enthusiast usage, Denverton is really cool, but is a splurge for someone who just wants an excuse to tinker with less-mainstream products.

Is anybody using an HP Microserver Gen10? Are they an awful value for money? I've been using an i5-4250u NUC that I got on eBay used for $110 with a 5TB external shingled Seagate hooked up to it as a VM host and NAS for almost 5 years now, and I finally want redundancy and more storage. I'm willing to have a somewhat weird low performance setup in exchange for better power efficiency than mainstream parts could get me, but I don't want to be like that dude a few posts up who spent $1400 for 16TB raw storage. My current plan is shucking 4x10TB Easystores into a Microserver Gen10, but I could just as easily put an i3 into a Fractal Design Node 304 or something. I want more than 16GB RAM, low power usage, and more CPU performance than a 15W Haswell. That's about all my requirements. Edit with one more question: I have found near zero info about the Operon X3421 online. My current understanding is that it's two Excavator modules on 28nm at 35W TDP, right? Looks to perform favorably compared to Atoms, and C3xxx atoms look like a miserable value for money overall. Twerk from Home fucked around with this message at 14:50 on May 13, 2019 |

Sheep posted:I have a Gen10 and it is awesome. The CPU is not some super stripped down or mobile line, but yeah information is a little sparse. My other option I'm looking at also has ECC and is cheap-ish, which is putting an i3 in a mini-ITX supermicro board. That would have IPMI and way more CPU power, but I'm not sure about overall power consumption or nice-ness of case. I'll probably just do the microserver. Do I need the SSD tray or can i just velcro that sucker in there? I've always just taped SSDs to the sides of cases.

H110Hawk posted:2 petabytes of write against that amount of host writes suggests offset issues. Though I haven't looked deeply into it. Yes I have had thousands die but in datacenter workloads, though most as os drives not heavy hit ones. (The heavy hitters nuked out way faster.) Yeah, I was curious about that but don't know how to address it in the future. This disk had a couple of hyper-V VMs, including 1 Win10 and 2 or 3 Ubuntu. It was running a plex server, minecraft server, Uni-Fi wifi controller, qbittorent scratch area, couple low-traffic NodeJS and PHP websites, TICK stack for monitoring & dashboards. I have no idea which of those was writing enough to hit even 150TBW, because all of them were extremely low utilization. I had configs and database backups and didn't lose anything that I will miss, but it was still annoying. Edit: I didn't need Windows, so I've already got everything set up on Ubuntu 18.04. I'll monitor to see what's writing so much, assuming that it wasn't something related to Hyper-V / Windows that was writing so much. DrDork posted:You're clearly using that drive for some business/enterprise workload: shell out a few extra bucks for a larger enterprise-level drive next time and it should last a good bit longer.

H110Hawk posted:What caused it is your host OS (Windows?) formatted the disk such that FS block boundaries were offset from the NAND ones. Two examples: Thanks, I appreciate this. Hyper-V was the host, with Windows and Ubuntus installed on it. I didn't think about VM OS disks block sizes at all, and there's a separate long-term storage system that's on hard drives. I just wanted to use the SSD as some fast scratch space. This drive should have been doing barely anything, so 150TBW does not add up with its extremely light usage. It's a mystery to me why it wrote so much. I also kept it under 80% full.
