Sometimes I hate enterprise hardware. Oh, you dare put a third party hard drive (that's identical to the certified ones we sell for a 5x markup) in our server? 11000 rpm fan speeds forever as a punishment. That IPMI command to knock the fan speeds back down that we've sometimes mentioned? Naah, we locked those out in a firmware update. Next time I'm buying supermicro, preferred suppliers be damned. (Dell R550.) E: Ah yes, the same goes for adding a third party PCIe card - they even have a specific guide on how to disable their paranoid/punishing cooling algorithm for those that doesn't work on the newest generation. E2: Ah, the racadm command to disable the PCIe fan speed thing still works. Shame about the drives, but I think I can move enough non-Dell drives to the external DAS. E3: Nevermind, with the PCIe cards calmed down the minimun fan speed with third party drives jumps to 36% for a bit but then falls down to 13% again on its own. Huh.

Either way don't buy Dell servers for home is my advice now. It's actually at work, but yeah, same thing applies. If I had a dedicated server room and the budget to pay for an all-Dell setup, I'm sure it'd be a great piece of kit. That said, I don't really have a lot of great alternatives; HPE are worse, and I'm very limited in suppliers. They have a couple of Lenovo and Fujitsu servers that don't really work for my purpose, and one or two annoyingly outdated supermicro parts. I can order anything from Dell, though, so ... R550 + MD1400 it is. And yeah I fully believe you; the fan speed algorithms on these machines seem to be mostly magic.

Connecting the second PSU if you have one installed to power also reduces the overall noise from the PSUs generally.

I did think about that, yeah - though disconnecting one didn't seem to change anything. As of right now the MD1400 box is noisier, which I guess is good enough. As for the MD1400, if you should ever need to deal with one: the SAS connector units at the back have debug USB mini ports (in 2022). If you plug it into a PC, they present as USB serial adapters - with two ports, though only one seems to do anything. Connect at 115200 baud, and you get a console asking for a password. Dell does not give that password out, but there is exactly one reddit post and zero other pages that have the right one. In the interest of doubling that count, its "bluemoon". You can then use the help command - it accepts the same commands as the earlier MD1xxx boxes did over serial, including "shutup 20 0" to set fan 0 to 20%. Any lower and it tends to go back up to 50% on its own shortly afterwards. There are two fans - one in each PSU - numbered 0 and 1. As far as I can tell it does not matter which of the two SAS units you connect the USB cable to. Beware, though - it looks like there's some foot-pointing guns scattered around in there.

A thumbnail image is made for every 2 seconds of video apparently, so yes. Though I don't get what they're storing that eats multiple gigabytes for metadata even with thumbnails etc off. They must be doing something like grabbing every possible cover picture and subtitle file, in every language / region they exist for, and saving everything locally. That way a user can switch languages on a client to instantly watch Seinfeld with subtitles in hindi or whatever.

I'm building a new computer and I wanted to consolidate JBOD 4 x 2GB WD Blacks onto 1 or 2 drives and was looking at the WD Blues. Did WD pretty much stop doing CMR for Blue drives ? Blue 4TB CMR (WD40EZRZ) is $100 on WDs site while the SMR version (WD40EZAZ) is $65. 8TB Blue (WD80EAZZ) is CMR for whatever reason and is $130 so I'd be getting a better deal just getting that instead of 2 x 4TBs IMO. I've never used a SMR drive so I have no idea how much of a performance difference SMR is over CMR.

Anything from Western Digital that's not Red Pro or their enterprise drives, or is 6TB or less, is at risk of being SMR. SMR drives can be used for WORM, but not part of some RAID arrays (particularly ZFS, but not exclusively so) because the thing SMR drives really suck at is random I/O and that's the I/O that is most common during a rebuild/resilver.

Yes. If you buy external drives and shuck them, they are CMR at the high drive sizes MREBoy posted:I've never used a SMR drive so I have no idea how much of a performance difference SMR is over CMR. The thing that makes SMR suck is that if you write a tiny 4KB file, the drive might have to re-write 1000 times more data to deal with the shingled zone. For media storage it's fine. First, you tend to write data and then leave it alone. Second, you tend to write large files rather than lots of tiny ones. The exception is that in many types of RAID, data will naturally be broken up into smaller chunks. So SMR drives have a bad rep in the NAS area. (Simple mirrors are fine though.) Another possible exception is torrenting, because there are clients that don't pre-allocate space and try to write all data as fast as it's arriving in lots of tiny blobs. I think most clients have improved this, but if you're doing tons of torrents on a gigabit fiber connection it still might be bad.

The usual solution for torrents is to have faster drives for the downloading, extraction, and post-processing and to transfer to larger bulk storage after the download is completed. It's not the worst use for old SSDs if you ask me. ZFS in particular is pretty rear end for torrent downloads even without SMR involved because of its copy-on-write nature but I believe newer ZFS versions are better about these kinds of frequent random write scenarios especially given databases and other high throughput use cases kind of want to do better with this algorithm as well.

I currently have transmission and sab dumping downloads to a folder on my system dataset, which is just 2 old 500gb blues in a mirror, while media and application data is on the main pool (4 drive RAID-Z1) - partly because I didn't want torrents interfering with media streaming or applications, but mostly because if I put it on the big array I'd forget to clean it out regularly, wheras this way TrueNAS yells at me when it gets above about 300gb. I only have about a 130mbit connection, but would the combination of ZFS and the relatively slow storage be slowing things down? I do get slightly better throughput from steam on my desktop I suppose..

You should hopefully know that limit from having run diskinfo -cit on the device at some point -so you have a rough idea which of your devices is the slowest, as that's what dictates the speed of any striped array with distributed parity. So long as you have IOPS to spare, your storage stack isn't really a factor.

BlankSystemDaemon posted:If scrubbing a video has to rely on thumbnails to be good, oppotunistic prefetching on your storage stack is either turned off or not functioning properly. Plex is solving for the case of people storing their videos at home and accessing them via internet where they maybe have a low bandwidth upload. You can't prefetch a whole movie, and bandwidth & latency makes scanning for keyframes (which is what a good local player like MPC-HC can do) not feasible. Plex could do dynamic thumbnails by scanning for keyframes itself, but that would mean a plex server had much higher system requirements to enable thumbnails. This is how youtube does it: That's 100kb for 25 thumbnails. (The original webp was ~100kb, I had to make it jpg for imgur.) This is a pretty efficient way to do thumbnails for streaming. The problem with plex is 2 seconds is stupidly low. Like, many modern video formats put their keyframes further apart than that. So you can't even seek with that granularity under conditions like streaming or re-encoding. Also I'm sure they're making the preview resolution higher res than it really needs to be, but if they had 5 second intervals that would be fine. (Also I don't know if plex is doing the same tiled palette thing, if they aren't they are super dumb.)

Oh, interesting. I saw that the total had stopped increasing this morning but I set it to run as a scheduled task and that's another thing I've never checked before, so I guess it's just stopped during the day. I have around 17,500 files in total. Most are an hour or less, so if I assume 20MB each that would put me at the entire remaining capacity of the system disk. I don't exactly want that but I don't have another use for it at the moment and I am curious, so I guess I'll let it run for a few nights and see what happens.

I'm finally sick of getting nickel and dimed now that cloud storage has moved to SaaS, so I've decided to rebuild a home server. I want to check with the NAS people first before I do, though. In the past, I would place 4 of the largest drives I could afford into 2 RAID 1s. Bad experiences with other RAID types kept me from experimenting. The other primary role of the server was to run Windows and then host several Linux VMs for various learning projects. Now I'm thinking the way to go would be to build a decent computer (i5-12000 series, 32GB of RAM, and a 1TB SSD, maybe?) and then get a decent NAS. What are everyone's thoughts? edit: I'm looking for around 10TB of redundant storage to start, possibly with expansion potential.

Do all consumer 2.5gbit NICs suck? We have two intel i225 cards in different machines, and both have a coin toss chance of just not working on any given boot. The realtek rtl8125 on my motherboard just doesn't work at all, which seems to be a common problem across multiple motherboard manufacturers who use it. I see the embedded intel i225 on the Mikrotik router I'm waiting for has a dedicated forum thread about its issues, too. I happen to have a 2.5gbit switch, so I optimistically thought that the NIC side should be a solved issue by now, but it seems kind of dire.

Those last two words are important, by the way - because data availability is what RAID is for, whereas redundancy when it comes to storage is usually something that comes about in the datapath itself (from using SAS Multipathing with dual controllers for each disk, all the way up to having active-active high-availability systems).
