It would be interesting to see Ceph running on this thing. CERN uses Ceph for data from the LHC.

The concept of cluster voting was developped by Digital Equipment Corp in the 1980s for its VMS clusters. The votes and quorum mechanism did not handle just failure of a node, but more importantly prevented a node that left the cluster from continuing to function (thus proventing it from accessing drives without enforcing locks/synchrinization with the other nodes). (called cluster partitioning). In the case of a 2 node cluster, you could designate a drive as quorum disk and give it votes, so any node in the cluster that still saw that/those drives would get the votes and could then continue. (in VMS clusters, drives could either be served by a node (and accessed from other nodes via network) or be standalone with direct hardware links to each node. (Digital developped extention to SCSI (called DSSI) to allow multiple hosts to access the same SCSI bus so multiple nodes coul write directly to the same physical drives). (later on, I beleive SCSI did get that functionality). The freezing of a node to prevent partitioning is very clitical to prevent a node that lost its connection to the other nodes from continuing to write to disks or perform tasks without the synchronization with the other cluster nodes. (in a cluster, there was a single lock database so when a process on a node too a lock on a file (or area of file) or a resource, that lock would exist on all nodes so processes on other nodes would not get that lock until first one released it). From a failover POV: You can have 2 nodes doing work since the locking is synchronized, so when one node fails, the other one continues and new network connectiosn all go to the second node instead of being split between the two. The other way is to have node 1 take and get lock and do all the work. Node 2 requests the lock but is put on hold because lock is unavailable. When node 1 goes down, node 2 gets the lcok and then processes all the work. Tandem NonStop (used for mission critical stuff such as Interac/credit card) has different fault tolerance. In the same chassis, a process would run on a single CPU/RAM, but a copy would run on a designated CPU/RAM, but basically have it writes to disk/network disabled. Both processes got the same data from network/disk. So the backup was a copy of the main one, and shoudl main one go down, the backup tok over right where the backup failed since the backup had identical RAM, process state and conections to network etc. However, while VMS clusters could be spread across multiple buildings (and up to 96 nodes), the Tandem Nonstop was within a single chassis in 1 computer room. so fault tolerant within chassis, but not disaster tolerant. A mere smb file server just blindly executes writes/reads from any node to any area of disk/file and when you have different windows instances accessing the same time, the last one writing to it wins.

To Add to the split brain talk, you need an odd number of nodes to guarantee they can reach quorum. Running only 3 nodes also creates issues when there is a failure as you now can't reach quorum and need to immediately get the node back up. When running 5//7/9 nodes outages are not nearly as urgent .

My guess is when you have more servers, the load on each is decreased, such that occasionally one can take a backseat. So with an even number of servers, by this logic, the failure of one server would not compromise the process and it would function as normal since the “extra” would not be needed right away and thus have more time to get resolved and back up and running. Networking allows the servers to handoff tasks to neighboring servers in the network. This is also why it was mentioned in this video that “two entire servers” can go down and not cause an issue and nobody would even notice. Also, the odd number discrepancy to check for biases, that’s usually an ideal for if you have multiple tasks computing at once that put the network of servers at full load, but otherwise an even number will still work fine as one is backup.

Excellent comment. Really excellent. The serious stuff for HA is not interesting for a general audience. Is pretty boring, even for us IT professionals. Is not "cost vs risk", it doesn't have the features for being redundant and secure. Is like building "the world's most powerfull PC" with $200, and then argue that well... it has prioritized costs... A recomendation? Just do it right, and if it is not right for a video, don't make a video about it, period.

@@maxhennessy6676 sure, but that doesn't make it HA... that's my point. You can't say "it's a discount HA", since there is a real name for it... just a failover cluster. Even if it load balances, still not HA. HA has many requirements and physical distribution is one...

Oh wow! It's an actual use for large language models and training that's ethical, reasonable, and useful! Incredible!

One thing I love about these server videos is that, unlike the high end PC builds you make, I might actually interact with one of these! Obviously not of my own, but as a professional software engineer deploying stuff for an employer. Even just making decisions based on what hardware bottlenecks will appear for different types of services! And the best part is not having to spend your own money on the outcome 😂

Until Linus said, "It would cost 50$ for 1 minute of downtime in payroll alone." I didn't really understand how much overhead he has. I'm a idiot so I probably did the math wrong, but there's 480 minutes in a day × that by 50, you get 24,000$ a day at least. So I 100% understand the need/want for daily uploads

You should try an IBM server sometimes!

This is a legitimately insane trio of cool new technologies that all add up to be greater than the sum of their parts: Supermicro's insane node architecture, BLAZING fast AND large capacity NVMe drives running ON A FILESYSTEM MEANT FOR NVMe, and that insanely cool AI detection software. I can easily see how just four rack units worth of servers, including these HA servers, GPU rendering servers, email/AD servers, and cold storage servers could conceivably run the entire infrstructure a major VFX house, versus previously needing a literal datacenter full of equipment. 1024 cores, 24TB of RAM, and 3PB of flash in 4U work of rackspace running at 100GB/s WITH a filesystem (over a network using non-optimal NICs) is WILD.

Holy frick... that AI scanning is hella dope. Excited for the road ahead for ya'll.

Jake is looking great. Looks like he’s been hitting the gym quite a bit

I love that server setup! Awesome!

I love the not jank era of Linus tech tips. This is more like a proper corporate setup than home lab setup.

Let’s get some popcorn and watch Linus drop it

This was a great video guys, thanks!

Ey! Long time no see Jake. Great to see you again man.

Cannot lose data… except when Linus has to be the one to replace a drive

Why don't you ceph?

I'd love a video on the evolution of Whonnock over time. I think that's good for learning how to evolve our home server storage over time. Fun fact: one of the Whonnock videos was the first LTT video I ever saw.
