This video is one of those random, should be on the playlist every beginner makes themselves kind of videos. Just for its random go off in a whole new direction learning surprising new things.

will ZFSs arrays typically support 10GB ethernet transfers or 25GB links?

the solder mask (green overlay on the pcb) can be different shades as they may use different bare pcb manufactorers depending on pricing. Even different lots from the same PCB MFG can be different shades. The best thing to look for is lack of ground vias in the counterfeit along with cheap chinese capacitors instead of better japanese ones

Can I install an optical drive?

I have this and and no screw. Been looking through my bit and pieces of computer parts but no luck. Thank you for the information 😊

While this guide is helpful and makes alot of sense, Im having a hard time getting CentOS on a bootable OS like you have. Do you have a guide on how this has been done as it seems to have been glossed over

sucks you can't do that to external drives anymore, they have started removing the sata interfaces

I can't quote statistics at the moment, but I've been very pleased with the apparent performance of the built-in LSI-2308 RAID controller on the Z840. There's also a built-in Intel with RSTe RAID controller that's supposed to be even more performant than the LSI controller on the Z840.

Done loads of these back in the old days with the SAS2 cards I could do them with my eyes shut but I struggled a bit getting this one to work with the SAS3109 quirk Thanks so much for this video it helped me get me sorted

$29 Australian eBay in 2024. I was shocked. Going to put it into my old HP Z 440.

Not all heroes wear caps. But those who make a video tutorials for smooth brained people like me, should.

Is it ok to run these in x4 mode pcie with spinning drives? I already have an lsi-9201-8i from your store. Looking to buy a 9207 for pcie 3.0 spec but still limited to x4 lanes. Thanks

The thing to bear in mind is that 92xx and 93xx are both regarded as "long obsolete" legacy cards by Broadcom and they've farmed them out to 3rd parties. Any new cards you may run across are OEM or _very_ old stock (at least a decade, maybe older) As a nice "bonus", these cards don't support ASPM and will keep your machine in higher power modes(*). That's OK in a server room, not so great for a SOHO server It's not just the power difference of the cards (1.5W/port in 92/93xx vs 0.5W/port in later models), but on my X10Dri motherboard I'm seeing the system base power load (no drives) almost double (50W to 100W) with 9200 or 9300s plugged in vs a 9400 9300 and earlier fusion MPT use a PowerPc core, 9305 and 9400 onwards use Arm core, which explains the power difference. Additionally the 9305 onwards support 24 ports natively so you don't have the kludge of the 9300-16's 2 controllers and a PCIe bridge bringing the things up to 25W/card (*) You _can_ enable L1 on 9300 series cards by forcing the OS and using setpci but you'll throw random intermittent SMART errors on a near continuous basis, so it's best not to do it Ok, that power difference is dwarfed by the 250W my (aging) 22 4TB HDDs are drawing, but as time goes by and they're replaced with fewer (larger) drives, it starts bcoming more noticable

what about the pdb i2c cable on non-SM mobos? No way to view/control the pdb if you're not use a SM mb?

Thank You very much!

Can you use this to say, see the VGA output for example if I were to install an OS on my server?

I have two PowerEdge servers, R620 and R730XD. After booting, R620's fan speeds fall down to 20% (which is not noticeable at all), but R730XD's fans remain at 68%. It sounds exactly like a plane taking off. I'm unsure if it's because of a faulty sensor, but the temperature graph shows 27°C. To address this, I created a temporary VM inside the server to send an ipmitool command to manually set the fan speed to 20% after boot, which worked for me. I monitored the temperatures and they remained at 26-27°C. Now both servers are running at 20% fan speed and they are barely audible.

oh wow, i didn't know counterfeit cards were this common. I bought a cheap LSI 9200-8i in 2020. No clue if its counterfeit or not, luckily mines is still working and has been running 24/7 since the day I bought it.

i am testing a Fujitsu D3262-A12 Controller U.2 NVMe SSD card PEX8732 in this configuration, hope this work for get pcie3

wtf supermicro... but perfect timing. will swap a regular atx mobo in a supermicro case in the next month or so. Thanks for this instruction ! :)

👌 solder free

Do you need to utilize a Supermicro motherboard with a sas controller to be able to utilize the backplane ?

Ya but that Fn key at the corner instead of Ctrl... =.=

Is there an HBA with internal and external ports? I have an mitx and it only has 1 PCIe slot, but I would like to add a DIY JBOD like this

Does it be the case with cards labelled lsi 9270 cv 8i, I brought it from ebay and it didn't work in hp z420.

The music was good... the work was... eh... Just kidding! Thank for the video and the lesson!

Instead of using a screwdriver I'd recommend getting a pair of something like fish bone tweezers and bending the tips a bit, that way they work very similarly to something like a keycap puller!

Repairable ok we take that

I did not know these were compression/sockets.

Is this the same for 9860 servers? I mean powering up n checking or a diff method ?

Stumbled upon this when I found out the 9400 and newer Broadcom "HBAs" don't have the ability to directly pass the hard drives or SSDs on to the OS and so things like SMART and such don't work. 45drives recommends the 9305, so my question is what are homelabbers going to do when the stock of these older HBAs dry up?

If I remember correctly most motherboards come with two ground pins for the power LED so it may be fine to just plug it in as is.

It mode mean and it what is difference give to people information.

👍👍

👍👍👍👍

Hey art of server ive been having a look at your channel and was wondering if you could help i am having an issue iwth a 9305-16e LSI HBA card where it will show the drives on linux but not windows Its flashed to IT and the drives are all umounted as NTFS but they dont show up on windows any ideas would be absolutely amazing !

Have you tried it with 32gigs of ram? Thanx!

Thank you for these.

Each lane 25Gbit and the connector aggregate to 4x25Gb so if you try with 4 parallel you get the same results like 8 lane. Or up to the cable it's qsfp or osfp. That's why you don't get much than 25Gbit on one lane.

If you want a cost-effective home server, get an HP microserver (G7). You can safely ignore the HP specs, I currently have two with 4x 6TB drives. One I have upgraded to SAS drives at minimal cost. As far as I can see, the only advantage of a Z840 (as a server), is that you can have four SAS drives without any other hardware changes. The downside is the cost of the electricity to run a high power workstation 24-7. PS I lust after Z840s, but not as servers.

thanks

I might be the first to comment on your Lenovo Tracpoint Keyboard II 👌

As long as the card has a properly stitched ground with adequate amount of (max spacing in between the vias based on rise/fall time of return path) vias and correct spacing in between pcb layers

I have storcli installed, but when I enter the command storcli64 /c0 at the Linux Ubuntu prompt, it returns the error message "storcli64: command not found". The command: dpkg -l | grep -i storcli returns ii storcli 007.2908.0000.0000 all Storage Command Line Tool, manages storage controllers.

So I tried the hack of no CPU and ram and I press power, nothing happens. When I go into ipmi and try and power on, I get please wait for a moment after acpi system status has changed. Help?

Are you available to support my team with the default setting? I will cover your time

Great video! I am pulling my hair out working with the CSE-846. Instead of swapping out the psu with 'less' loud psu, are the small loud fans in the psu swappable to quieter ones? Thanks!

So my X9DRi-F can run without CPU and ram? I plan to use my 4u as jbod as well

nice one. such a detail video. Thanks
