Hello can you please do me a favor and help me find which type of sas controller do i need i recently bought 2 SAS HDD 3TB each and i have 3 slot open on my motherboard “pciex8” “pci” and “pciex4” im so noob on this type of stuff i would appreciate if you can send me the link or name for the controller card THANK YOU!!!🙏

Just stumbled across your channel three days after buying a r730xd. Boy do I have a lot to learn.

hello, unfortunately I saw your video only now and I ask you a favor if you could suggest me the correct sas cable to connect it to a third-party controller such as a dell h200 or lsi 9217-4i-4e or with adaptec controller always with sff-8088 connections. thank you very much

Never thought about it before... Got it now... Wood bad.

Very help full. Thank you. i do have some ST1200MM0018 2.5" units that formats but once trying to initialize or format for windows does not allow indexing and format.. Any idea why? HD sentinal shows 100% health and no issues.

more than one way to skin a cat :) I just do the command with & at the end so it goes to the backgroup and do it 24 times. Lots of txt on the screen bit it works! good video though.

Can you recommend a raid card the will work with the 3par and windows 10?

This video helped me out tremendously a few months ago when I found a lot of cheap hard drives and decided to setup a homelab. I think I was a little overzealous when I first saw this and bought the linked LSI 9200 card without really understanding the difference between an HBA and a RAID controller as was discussed towards the end. If you're like me and setting something up for ZFS/TrueNas you're gonna want to go for something like the LSI 9211-8i instead, as the MegaRAID cards will not be compatible

Fun project! Love your videos by the way, the knowledge you share is valuable. I should leave more comments and questions. I've personally wanted to put together a "compact" NAS comprised of 24 or more NVMe M.2 or U.2 drives (M.2 better for thr compact plan I'd guess) but it's a difficult ask due to the PCIe lanes. I guess the only way would be to do something with an EPYC CPU (Siena?). I just wonder how it could be put into a compact form factor or if it's infeasible.

And can i change processor

Is any internal ssd upgrade options

There is no way you are a storage architect. You have a below basic understanding of controllers, RAID, zfs and disk management …

What is the maximum capacity hard drive you could put in here?

Max Hardcore is building servers for hosting his masterpieces???

may I know what is the OS and what infrastructure are you doing to it? is this good for home lab?

Great information. Thanks :) You have RF shielded your walls - when it's time to consider doing that? Can you provide some photos of how you're grounding your Racks - Every equipment should have individual ground wire to a Rack, then entire rack wired to a wall outlet ground? Is that considered safe to ground a rack to a wall socket?

1GBe makes the pi useless as a nas imo. Not even gonna talk about the PCIe 2.0 1x. There are solutions not much bigger but way better

I want to learn more of those. Can you provide more information - or a documentations to look for here? I'm looking for building my first homelab - and want to work in industry when I will feel that I'm ready for it. Are you referring here CIS, DISA STIG etc. or hardening systems even further?

I bought a MD1200 and I hated it so much. So heavy, loud and obnoxiously bright. So I ended up building my own DAS, which is way quieter because it uses bigger fans and it has a faster, more efficient controller while being able to handle more drives. Much better

I run 4x1tb firecuda 520 in my dell adapter and am very happy.

Hi Brad, I have often found in my office/lab that heat has always been a big problem. The principle reason is this area is downstairs in my home, therefore has double brick walls and also faces east. The brick walls act like a heat sponge during the morning and make it near impossible to remove heat from the air inside the room during the height of summer. At one point I had 3 42RU racks in a much larger room with most of the gear running 24/7 which included 7 or 8 HDD shelves and DL380+580 servers associated network gear. At one point this “large’ room had a high temperature of around 36 degrees in the middle of summer. Not good at all. I ended up dividing the same space, about 8 x 3.6M, in half. Although I have not finished yet, I’ve calculated I should be able to run the same gear in a smaller room, but with hot and cold aisle type set up, the room can be kept at about 28 degrees C. The hot aisle faces the hot front brick wall of my home. Still not ideal, but this is only applicable when running my whole lab flat out……which doesn’t happen often. But still allows me to use the same heat pump gear, much more efficiently. Which is just one of the things we learn as we go. Also having worked in the HVAC &Building Automation industry at one point has helped. Take care Brad.

Thanks for making this video. Just to understand, does this mean when you use the previous SAS/sata connector cable you are halving the bandwidth to 6bbps as opposed to using this cable which is SAS to SAS providing 12Gbps?

Purposely degrading products and services seems to be the norm. Interesting video👍

Brad, I have watched you for only a few years but I love your videos

Is it as easy as changing out the boot drive SSD with another one even if the replacement drive is not empty? Im referring to the cards that go in that J4/J3 slot that work as master/slave on ada1 and ada0

Interesting video!

This is true. This is what we've discovered with the Nimble AF40 arrays. The controllers would bottleneck before the SSDs reach capacity.

If you factory reset will it clear data

Beautiful

How does your proposal differ from a mainframe? I have a feeling that once you start building a low latency topology of hyper-converged machines, that's kind of where you end up. A video comparing those concepts would be interesting from you, as you've put a lot of thought into this!

pcie bandwidth might be a bottleneck to utilize all possible devices for each machine

There were a few clustering operating systems back in the day that allowed distributed processing without having to rewrite code. The projects died off when multi-core CPU's became ubiquitous. I have always liked the idea of spreading the load across multiple machines - I have lots of computers. Your idea of extending the processing further across GPU's NPUs etc is awesome!

Two thumbs up the audio no clothes where you go I'm really happy for the change

A LONNGGGGG time ago, there used to be Cluster Knoppix, which boot up off a Live CD. Worked quite well for what it was.

Was watching a completely unrelated video and youtube recommend. So your in the algorithm somewhere. I will say your lab setup is intriguing. Just started to consider using proxmox in my homelab recently.

Hey Brad, I’ve seen a couple of your videos and every time that server rack stands out can you go over it and show it. It looks super cool. Cheers

The obsolescence cycle coincides with the megapixel / lens multiplier cycle too. The image sensor resolutions didn't outpace the capacity for displaying them unscaled so many times over to meet provisioned user needs or even on-device features. They don't enable remote service delivery to the user, they supply remote data for any purpose parties using tools and applications with administrative access enable them.

Sr. ,,,can i conect it to a TV via HDMI cable and eliminate monitor??

Just got one on eBay for 50$

Wonderful video.

What a buffoon. To you, the creator of this video, I suggest that you watch it and ask yourself if any viewer could understand it.

My personal opinion as IT-Professional: Personal Devices are a godsend for corporate IT. You can force your users to use ONLY specified Services and connections with their devices. And we all know, your general User is very much too uneducated and simple minded to handle a whole operating system. The Money on the other hand is quickly fixed , if you consider manufacturing large quantities for your corporate directly from factories. As this is of course only possible for bigger companies, smaller ones need to rely on vendors. I remember Apple offering a specific version of their SE2 to us, because we had a limit of 450,- for a singular device. Anything above that would've needed special approval. So we got the most barebones packaged SE2's without charger and any kind of booklet.

I used a sata disk to install centos. This drive does not have raid. I then attached a nettapp x371a sas ssd 12gbs drive. The system has recognized my drive. But when I install sg3 into centos and then use the sudo sg_scan command, only the drive where centos is installed appears, the sas drive is not recognized. Therefore I cannot use the command sg_format --format --size=512 /dev/drivename. Can you help me see where I'm wrong? Or do I have to use untubu?

please answer sir.. 1. Is the Dell Precision Rack 7910 a server or workstation type? 2. Can the nvme drive be used as a boot drive? thank you

Will this create a computer with a higher cpu power output

I agree full classic system being more and more integrated as a SOC is the pretty clear next step.

I'm very worried that there will be no room for the magic smoke anymore?

Thanks very impressive, and I remember all the old cables and standards too. All the best Joseph
