New Home Backup Server (Dell T640 with 18 20TB Disks)
In this video I create a new backup server from a Dell EMC PowerEdge T640 with 18x 20TB Seagate Exos refurbished drives. Also there’s some more ranting about backups in general. But idk, there are chapters so you can skip to whatever. And it’s not technically a server, in that it doesn’t serve files. It’s really more of a client that takes files from other servers and holds onto them. But I call it a backup server because hardware-wise it’s a server. Anywho, that’s the description. It’s probably not optimal for the YouTube algorithm, but hey, I’m not an influencer even though I have a TikTok account that I don’t use.

————————————————
Why Learn Cyber Security?
Cybersecurity is the gathering of advances that procedures and practices expected to ensure systems, PCs, projects and information from assault, harm or unapproved get to. In a processing setting, security incorporates both cybersecurity and physical security, it is imperative since cyberattackers can without much of a stretch take and obliterate the profoundly grouped data of governments, defense offices and banks for which the results are huge so it is essential to have an appropriate innovation which an avoid digital wrongdoings.

Leslie Lamport revolutionized how computers talk to each other. The Turing Award-winning computer scientist pioneered the field of distributed systems, where multiple components on different networks coordinate to achieve a common objective. (Internet searches, cloud computing and artificial intelligence all involve orchestrating legions of powerful computing machines to work together.) In the early 1980s, Lamport also created LaTeX, a document preparation system that provides sophisticated ways to typeset complex formulas and format scientific documents. In 1989, Lamport invented Paxos, a “consensus algorithm” that allows multiple computers to execute complex tasks; without it, modern computing could not exist. He’s also brought more attention to a handful of problems, giving them distinctive names like the bakery algorithm and the Byzantine Generals Problem. Lamport’s work since the 1990s has focused on “formal verification,” the use of mathematical proofs to verify the correctness of software and hardware systems. Notably, he created a “specification language” called TLA+ (for Temporal Logic of Actions), which employs the precise language of mathematics to prevent bugs and avoid design flaws.

Hi Scott, excellent video, thanks so much for sharing 🙂
Two comments from my side:
– Regarding snapshots, you could use btrfs with built-in snapshots (like on Synology). This way you get free data deduplication and still keep the snapshots principle going, to protect against malware. Data would only be "duplicated" in case of being overwritten by malware.
– Not sure if it's an overkill, but I do new HDD burn-in with badblocks -wsv You can choose how many runs etc. Takes quite a long time, but gives good confidence imo.
My two cents. Thanks again for the great video!

Split it up into 2 x Raid 6 (z2) 8-wide HDD arrays, with a hot spare each. A single one of those arrays should just saturate a 10gbps nic.

The huge empty slot bay cover will be the basis for stuff like card readers to be added with a bezel change. I have an HP server with a similar feature. if you don't need the PCIE lanes or the cores. Taking out the second CPU will reduce your power bill.
You are correct about the CPU 2 expansion slots. You need a second CPU to supply the PCIE lanes for them. A similar deal if you want to use all the RAM slots. A second CPU to use the slots for it.

Many people do not take the rebuild time risk into account. I have explained it many times, and often people are not even paying attention. People nowadays are more and more used to social media information overload and they just feel and react. It's funny because in the hard sciences, engineering and business, we used to look funny to the social science students deciding what is true because it "resonated with them" and today it's mainstream. Flash-based SSDs have a pretty bad write speed (out of cache) but can still perform many more IOPS. They are still expensive, but they already 15TB in the mainstream.

for the T630/T640 I like using the MB998IP-B (icydock 8 bay 2.5'') and the D P/N 010WY power cable.
the 18 bay chassis is a little short on 5.25 space, and comes with a one sata power cable. using the mutli-head power cable saves you needing a power splitter. and the 8-bay icydock has two 8643 mini-SAS connections which are FAR more convenient than using 6 or 8 (especially locking) SATA connectors in such a tight space.
the T630 has SAS connectors on the motherboard. though the T640 has oculink, but can be adapted to SAS 8643 fine. (or pcie if you are exceedingly daring)

Not impressed at all. no need to be swearing.
@leexgx
October 16, 2024 at 8:09 pm
(I am editing this as watching it) It’s really too bad There isn’t a raid 7 for software or hardware raid, i’m surprised that you didn’t use zfs or truenas core for z3 (there is a new os in development called hexos to make it far simpler to use truenas as I find it annoying to use)
if you are using md raid it does support live replace so if the source drive is still functioning you can do a source and target for drive replacement it basically makes a raid6+raid1 mirror with the spare drive once miring is successful it removed the old drive (any uncorrectable read errors will be handled by the parity to correct them the rest of it is done as a straight mirror from the drive so all the other drives stay idle) zfs also has always supported live replace and is the recommended way if the old drive is still working
When buying used dell make sure it has included idrac enterprise license (slightly annoying my 3 blade server I got extremely cheap only had basic so I lost remote access control after 90 days as it converts to basis after trial ends and the idrac key costs more then I paid for 3 dells)
Also what I use for boot is pci-e 2x sata m.2 card that pull the power from the PCI bus and 2 sata cables from the card to plug into the motherboard sata ports (Most dell servers have at least two on board) use raid1 mirror boot
Too bad we didn’t actually see the wait times because it looks like just from the front of the Dell machine drive lights (guessing 40% utilisation ) and It is running the rebuild on one thread because when it means 100 that’s 100% of one thread not every thread on the cpu (that will be like 800 assuming 8 threads available)

Since you are serious about your backups and already have a capable server, then I would definitely split the array at the cost of usable space. Used system, used drives – it's not that hard to have an error on the array and every time it happens it will resilver or scrub. On ZFS maybe 2 RAIDZ2 vdevs or 4 RAIDZ1?
@daven6634

Just found your vid, this 3.5" x18 is the configuration i want to upgrade my R730 with. It's interesting that the 14g T640 use the 13g drive caddies/sleds. This is great because the 13g caddies are a lot cheaper.
I got my R730 idling at 120W with 8x 3.5" drives. I couldn't find it in the comments, have you tested what the T640 idles at with 18 HDDs?

@dagamore
October 16, 2024 at 8:09 pm
because it is a backup system why did you go with mdam vs zfs, zfs allows for snapshots natively and with scrub/re-silver is an easier process for replacing failing drives.

A couple of things I didn't get to in the video if anyone was curious: Noise was about 55dBA @ ~0.5m from the front of the chassis with the disks under full load (array consistency check). At idle it was 45dBA at the same measurement location. (Though one catch is that it was in a small and otherwise empty/echo-y closet, which probably made it measure louder than it would have been in some kind of proper acoustic chamber. Mainly I was concerned with relative measurements, so it served well for that.)
It drew about 105W at idle without any HDDs, and ~235W at idle with all 18 HDDs installed. Under full disk load it was almost bang on 300W most of the time.
To put the sound in perspective, the previous setup was about 66dbA. That was mostly due to the HP D2600 DAS that was perched on top of the old server. (I had spec'd the server itself to be super quiet. Didn't measure it independently, but it was much quieter than the Dell for sure.) But one important thing with sound levels: The D2600 fans ran faster and were of a much higher pitch and buzzier than those in the T640. So even with the disks working hard, the T640 "felt" far quieter than just that 11dB difference. It's more like a low "woosh", and not distracting or uncomfortable to be around… though of course that's fully down to personal preference/tolerance.
I should be posting a follow-up soon, so you can see and hear what I mean. And here it is now: https://www.youtube.com/watch?v=Secv5P01k2M&t=5195
