The price of Optane is still nuts. Often times, RAM is cheaper. Will ZFS just use RAM if it's available to cache that metadata?

[@wayland7150]

ZFS caches everything in RAM given the opportunity. RAM is a much faster cache and the size available these days should be plenty. The Meta Data storage does sound exciting however you need at least two Optanes because they are critical to your stored data. They also must be big enough. I think I will stick to RAM as cache because when I tried normal SSD as cache it actually slowed down a lot for large writes such as virtual hard drive files. An array of 4 drives is actually quite fast.

[@ndragon798]

I tried doing the "find . | wc" not knowing that I had enough ram for zfs to have a copy of the metadata in ram or atleast thats what im assuming was causing it to return in 1.356 seconds with 117265 files. This is against a raidz3 of 12 1tb spinning disks.

[@georgebrandon7696]

Whatever is in RAM doesn't survive reboot. That's the whole point in PERSISTENT storage. It's there when you need it. Don't have to wait for it to load up the RAM every time you have to reboot. And if you're running SQ, RAPIDS, or anything else which loads into RAM? Does you motherboard support more than 128GB? Because all that stuff in RAM adds up quickly. I don't have time to sit here and wait for that rust to be loaded into RAM., When I need it, I need it. Persistent storage is a thing for a reason.

I really wish ZFS would let you have two L2 arc caches and be able to set one of them to metadata only, but it seems like that is a setting that applies to your arc caching globally? Metadata l2 arc just seems like it should be better for light/home servers, only one disk without redundancy requirement, sounds like less risk with better MB compatibility, althought it seems to exclude having a second l2 for data.

[@СузаннаСергеевна]

If your concern is wasting valuable L2 capacity on something that doesn't need to be there, you can use datasets to restrict which folders get to put all their stuff in the L2 and which only get to put their metadata there. For example pool/anime could be metadata only, because your anime collection doesn't really benefit from being cached, while pool/games and pool/home could be data+metadata, because those do benefit from the cache. If you're talking about having something like a 1TB NVME SSD as the data cache and a 16GB Optane as the metadata cache, you should probably reconsider your setup. L2ARC needs to maintain a lookup registry in RAM, sort of like a metadata of itself, and that steals capacity from your primary ARC. Adding too much L2ARC, unless your system has 64+GBs of RAM or something already, is probably going to harm performance rather than help, because the data that otherwise would be kept in super fast RAM now needs to be read from a comparatively slow SSD instead. ZFS also isn't great at NVME SSDs to begin with. It's tuned for HDD, which means rather than flooding the SSD with every request it can find, which NVME loves, it will carefully sort the list by sector and issue it a few IOPS at a time, which is great for HDD and doesn't really matter for SATA SSD, but really isn't a good way to handle NVME. You'll have a better experience just formatting your NVME SSD with XFS and using it for your root/home/game drive, running a nightly rsync to back it up to your ZFS pool.

[@СузаннаСергеевна]

That sounds like a pretty profligate use of an Optane. Why not just get a USB DOM and put one of those extra USB2 headers cluttering the motherboard to some use? 8GB DOMs are dirt cheap on Aliexpress and more than fast enough considering you're only spending a minute per boot reading from it. Once your NAS is booted up the performance impact of having the kernel and /usr on a USB2 flash drive is negligible, all the files it accesses regularly are cached in RAM anyway.

PrimoCache is very good when using Optane as the "L2" cache. I have 4x1TB NVME (Intel 670p) that have 512GB of Intel Persistent Memory (1st gen) in front of them and 32GB of DDR4 ECC 2666 in front of that. The whole setup gets about 18GB/sec in Crystal Disk Mark for the Seq 1M Q8T1, but 680MB/sec in RND4K Q1T1. Latency is around 5 microseconds. I can't really recommend the Intel 670p, but I wanted a full-Intel stack to avoid issues with VROC (it's RAID0, just for games so who cares if it goes up in smoke). It's a shame that prices on Optane were so high and that now it's all being tossed out like this, I would have liked to see an affordably priced solution like the H20 but maybe using 2+TB of NAND and, well, a meaningful amount of Optane for gaming-like workloads (or other desktop-class use). If this had come as a PCIe x16 card it wouldn't have been a big deal, but it probably would have worked better than having to rig up something like I have. Also, the Solidigm tool that replaced the original Intel one for the NVME stuff is slow and clunky. It's such a shame it all went the way it did, but oh well.

Is SSD/NVME caching worth while, if you're a home user w/ a dedicated Hardware RAID controller that has 512MB/1GB onboard RAID caching?

Yeah, not worth it. The problem with normal NAND flash is that when it's writing hard it gets really slow. This is true when it's storing stuff for reading too. This can actually make a fast array run slower than without it. The reason NAND flash devices are fast is they have caching of their own, when this is saturated they are actually quite slow. The on board caching of your card sounds much better. The operating system also does some RAM caching with whatever RAM is not in use. Adding more RAM to your system helps even if technically it has enough, the excess becomes cache.

I use two of those U.2-to-M.2 adapters to connect both my Optane 905P and Optane P5800X SSDs to my PC. The 905P came bundled with the adapter and works at its native PCIe 3.0 speed. The P5800X didn't come with an adapter, so I bought one on AliExpress which was was only certified for PCIe 3.0 but actually worked on the P5800X at its native PCIe 4.0 speed without any issue. Basically the adapter cables are simply wires while the AIC adapters need to explicitly support PCIe 3.0 or 4.0. Intel CEO Pat Gelsinger's decision to kill off Optane was a very bad mistake in my opinion.

[@2intheampm512]

Damn where'd you source the P5800X

[@gagnon124]

well they do not seem to be on sale in canada

[@BikingWIthPanda]

using jim salter's articles for ZFS documentation is going to mislead people. he never admits when he's wrong, never updates old articles. his site is full of dead information that no longer applies.

[@Chris-yc3mm]

Is this a US only thing? I've checked a few places in the UK and optane looks as expensive as ever :(

[@jierenzheng7670]

Sad to see Optane go frankly. Was hoping to see something more from it.

[@mckidney1]

At least LVM got a shout out :) Even if I sense some hesitation :D

[@wishusknight3009]

Would raid one be sufficient for a special volume?

[@emancesooh]

Ordered 5 of the 118gb on this deal around a month ago 😁

[@jeffclark5206]

Is the 905p still the best OS and application drive over say a Seagate Firecuda 530?

[@JacaYT]

It is. Low latency at QD1 makes your OS snappier than any NAND device. You also don't have "glitches" when drive fills up, or garbage collector kicks in.

[@danielsnyder2288]

Not seeing these prices anywhere on new egg. Was that a black Friday only price

[@Usmankhalid-z8k]

What could you do with those 16 gb drives in 2024?

[@VelcorHF]

fk, I'm too late on this. You are blowing up prices wendell! :D

[@JacaYT]

They are back in stock! Grab while they last 🙂

[@jamesbutler5570]

Actually radian rms200 are on sale to. 2gb ddr3 with supercap protection.

[@JourneywithBrandon]

I'm working on my first build, 5x14TB. No idea how much I would need.

[@InquiringJoe]

What is a good ratio of optane to HDD?

[@jllerk]

This is just an insanely compact beautiful masterpiece, thanks for this great advice!!

[@jllerk]

Yes you see this right. I replied Trice!

[@SilverBullet27188]

Question, how much worse is are the consumer SSDs?

[@Y0URGRANDMA]

Consumer ssds certainly aren't getting better with durability like how the 980/990 pro are half as durable as the 970 pro was for caching.

[@denvera1g1]

7:58 I wish motherboards supported bifurcation in x2^8 mode so i can get full PCIe 16x bandwidth with 8 of the 118GB drives.

[@AlexSchendel]

Whoa, 11 months later and those Optane drives are even cheaper on a Black Friday sale?? Might have to snag one for my NAS! Not to mention the 905P has some even crazier deals... Maybe just snag a 905P and partition it for both a SLOG and L2ARC haha.

[@be-kind00]

When you say "striped three way mirror" are you referring to a traditional Raid 5 with three OptAne drives?

[@thomashong7]

Not raid 5 more like raid 10 but ZFS in THREE 2-way mirrors

[@scottylans]

Does anyone know what those m.2 cards are which you need to purchase?

[@TheSimonarne]

I use one of those 16gb as a dedicated swap drive in some of my machines got 2 for 20$ or so a year or so ago

[@gucky4717]

Sadly in Germany those are still freaking expensive... the 118GB goes for >700€ or are not available at all.

[@polik971]

400€ here on Amazon Italy. Damn...

[@Blacklands]

Yeah, they barely seem to exist in Europe. :(

[@-blackcat-4749]

The displayed position is unsurprising. As things 📆 go

[@yasyfawiwaha4088]

Is there really nothing you can do on the 16GB ones? I can only find those in my country, seems like a fun project to work on for dirt cheap.

[@wayland7150]

Waste of a M.2 slot. Might be OK on a desktop system for Windows system on a HDD as a ReadyBoost drive. I've found that ReadyBoost really does help. It does two things, it stores a file for fast booting, it assists with other MS tech for speeding up loading. The problem is the systems that benefit from ReadyBoost are usually old ones with no M.2 slot. An SSD C: drive would be much better.

[@brodriguez11000]

@@wayland7150 Well with current PCIe 4.0 NVMe drives booting from cold is pretty fast. ReadyBoost doesn't shave off that much time.

[@wayland7150]

@@brodriguez11000 PCIe 4.0 NVMe hard drives, crikey.

[@videocardzrule354]

Anyone try a Optane P5801X E1S? Are there any E1S to PCIe Gen4 adapters that are confirmed to work?

[@timramich]

I am on this thread where it shows how to list the number of files by size. I don't run ZFS yet, but I want to when I get new drives. How do I know how large of Optane drives I'd need? I would not be using the special_small_blocks feature. It would just be for metadata.
