In the grim darkness of 2025, Linus tech tips finds itself barely recognizable as thousands of servers coat their buildings like a 2 meter thick layer of armor, shielding the world from the madman at it's heart. Inside the asylum, a monument to the sins of Linus' technology addiction, he slaves away streaming 24/7 as he tries in vain to "save the universe" in sever project after server project. His employees are wired directly into everything as little more than motherboards waiting to be dropped by Linus. As time goes by, Linus will himself finally become the master of the internet as he wires himself into his temple of tech tips, continually giving tips about tech so arcane that they are lost upon the ears of the masses. In the year 2025, Linus tech tips becomes unknowable, unrecognizable, feared, and worshipped.

Finally, they are doing it right, I've seen so many of their setups and thought, well if that works best for you and the team, then cool.

Your storage is starting to look strong now LTT, sweet !! ❤️

@archaon8853 Год назад

Going from something like glusterfs to what's effectively just a single file server really isn't an upgrade. However if downtime isn't a particular issue and there's no need for clustering etc then it's an ok solution that's much easier to manage, and sometimes that's more important than how good the tech is.

12:19 Biggest thing I have to deal with as a datacenter Storage Admin is constantly checking people that assume Storage doesn't need lots of host resources. Perfectly competent technical people somehow miss that processing and handling IO isn't free in terms of system resources, both at the Storage System AND Host Initiator sides. 20:20 Metadata dedicated is a godsend for huge fileservers like yours -- The idea is that filesystem metadata lookup is actually a really big performance hit because metadata reads/writes are very small, very random, and usually with a sync_required status so they hold up the line. With a metadata tier, you put all your metadata in a dedicated high performance tier/pool/spam/whatever and it not only speeds up your metadata activity, but it also keeps your other storage open for regular IO without having to shudder around working those small metadata IO packets in the middle of regular workload.

@QualityDoggo 2 года назад

Well... for most people storage truly doesn't need many resources... any computer within the last 10 years could probably serve as a 10TB 1-drive NAS. But the little bits of processing power really add up when you have multiple petabytes... not to mention the sheer bandwidth just to keep so many drives happy. Add a NAS-grade filesystem like ZFS and it's a lot of work for any system.

Relative to the size of the system, it's not that much power since it's literally just spinning up disks plus minimal power for the SAS IO module and expanders, IPMI board etc. You can use more than that in a 1U server or a workstation if you want to. Couple of Xeons or Epycs and a couple of GPUs and you're already past that.

It's very cool but from what I've heard LTT has like 50 employees. This is like 26 Terabytes per person if you are doing a 1-to-1 backup (and not all employees will utilize this fully). Perhaps LTT has a larger data inefficiency/clean-up issue? A media company of this size should not/does not need this much storage. It's definitely cool but it seems like for the past year or so we've been getting server upgrades pretty often. It seems like a bandaid solution to a larger problem IMO. It may be in LTT's best interest moving forward to hire someone to establish standardized procedures around data retention and general operational efficiency. If these things weren't sponsored like they are LTT would be breaking the bank just trying to keep up with its data problem.

@ashleighrowe2565 2 года назад

you are aware that they keep all old video footage for archival purposes, right? A media company this large, i'm actually surprised they're *only* using those Petabytes. yes, they could delete their old footage, and to be honest, for archival really going to tape would be cheaper and in their best interest, but they've not got a data retention problem, they just have a lot of data that is considered to be relatively valuable to LTT

There's one cool thing with ceph : it makes data loss *reaaaly* unlikely, because when an error is detected, as long as you have enough space left in the cluster, in terms of redundancy, and space, it will recover automatically and after that, even if you didn't change your bad drive, you'd have the same amount of redundancy as before the drive went bad, you just lost the drive's capacity, and usually you don't let such a cluster fill up to the point where it's unable to do that, and you expand before. Also, ceph is a joy to expand : make the node join the cluster, create OSDs, done. Ceph will automatically rebalance the data if needed. Same thing if a node goes down, if there are enough nodes left to keep the required level or redundancy, it will automatically rebalance the data to make it happen. We use this in our IT club at our uni, it saved us multiple times, keeping our infrastructure up and running even when we f things up. It is capable of recovering from very, VERY bad situations. There was a time where we didn't have the "manpower" needed to replace bad drives in our cluster : if was fine : ceph kept these bad drives out of the cluster and rebuilt the redundancy, so even after all the drives of a node failed (bad HBA card), some within days of another, with no manual operation, there was no data loss, only capacity loss, which was fine, as we overprovisioned. Truly a marvel. In comparison, ZFS is only *good*, I think, a lot less flexible, certainly. Edit : also, ceph is able to handle drives of drastically different capacities, and handling it as best as possible, without much intervention, if at all (depending on the crush rules, etc ...).

@v1mja 2 года назад

Jup. Ceph is absolutely amazing. We ran our cloud on GlusterFS and absolutely hated every bit of it. Now we are running on Ceph. Every issue we have encountered has been just so pleasant in comparison. Drive failure - no sweat (as you explained above, Ceph handles it so well. I'll replace the disk just whenever I feel like it). Expanding the cluster - It gets faster as a bonus! Bitrot on a drive - detected and fixed reliably. Rebalancing the cluster after a node-outage or adding new drives / nodes - works as expected with virtually no ill-effect on the performance delivered to VMs.

Meanwhile: Dual Epyc is around $20k 3.2PB of drives is around $60k JBOD box is like $10k That's $100k one time purchase vs $200k a year.

@XIIchiron78 2 года назад

Yes you can do something similar, the setting is called "pin all metadata to SSD cache", if you Google it synology's support article comes up

24:22 Jake you're running 16 jobs all to the same drive, this makes it more random. You should be good enough with a single job at 1m block size. Your real world performance will probably be similar to what FIO showed if your application or RAID software doesn't serialize what is possible. Also SES pages should show drives connected in one of the pages

@bronekkozicki6356 2 года назад

Since you seem to have missed it - a loss of SPECIAL (metadata) device will result in the total loss of data. I mean, the data without metadata is useless. If you were to go this way, I would suggest splitting this device across disks in different locations - e.g. a mirror with half of it in the JBOD. Which kind-of kills most of the benefits.

@ashleighrowe2565 2 года назад

you may have missed that Jake was suggesting using redundant SSD drives for that. yes the loss of data risk is still there, but given they're doing RAID-Z2, the loss of data risk is there too, and with the AFR of a SSD being lower, on average, than that of a HDD, assuming you get past the start of the bathtub curve, the risk is not any more raised by using the special metadata vdevs on a SSD like his suggestion than it would be staying on the drives that are there already, especially as Jake has 3 cold spare of those drives ready to deploy in the case of a failure of a drive

@bronekkozicki6356 2 года назад

@@ashleighrowe2565 Bathub curve applies to the risk of single disk failure. In case of a critical device such a SPECIAL, it bears to consider other sources of risk as well, like for example accidental wiping of all disks in a single computer chassis. Normally "accidental wiping" is not much of risk, but you know - Linus Sebastian has his ways :^-D

At this point, you SHOULD be running a robotic tape library by now if you're running 3.6 PB of raw storage for archive. There's literally NO excuse for you NOT to be running a robotic tape library by now. But yes, at startup, because the system doesn't know the state of your environment nor the thermal conditions of the drives, it will run the fans at 100% (which is not unusual/uncommon) until it gets the environmental sensor data and the drive temp data and it will start ramping down the fans. The old Sun Microsystems SunFire X4200 was I think rated at something like 106 dBA for the front six fans that it had. You're getting into data center class/hyper scaler class hardware and leaving the realm of "normal" business/enterprise grade hardware.

I love that you have finally done a episode on jbod and head server. I have been looking into this for a home or small business. There is not much on you tube on this that clearly show you how to build a home or a small business level. Would you ever considering on doing a episode on how to build both jbod and a head server and how to connect them.

@archaon8853 Год назад

Obviously depends on capacity or number of drives but for home or small business you would normally use internal disks. A server chassis with say 12x 3.5" drive bays and internal SAS or SATA controllers is way cheaper to buy than a server + JBOD + external SAS + cabling, it's less to worry about, less space, less power, etc. Also to be blunt if it's just file storage, then unless you want to nerd out for the sake of it - just go and buy a NAS from someone like QNAP or Synology.

@Fren160 2 года назад

Having worked a lot of these types of servers in DC environment, you're going to want spares of: the external SAS cables, HBAs, drive sleds, the controller in the back of the JBOD and possibly the backplanes too. Also, if your rack isn't already floor mounted I'd recommend doing that as well since these pose a decent tipping hazard when extended in a rack. May also be time to get a room cooling solution better than the AC
