- Introducing a Dell R7920 Precision Workstation to everyone here. This thing is really freaking sweet. It's actually an R7920, a rack mount form factor of the T7920. AKA the Tower 7920 workstation. The R7920 is basically a R740 but at a steep discount. Check out what the hardware I got and you might understand why you need one too.

I love those Dell rackmounts ever since the PowerEdge days. Maybe i'll revisit once closet is finished. Great content as always!
The rail system alone is to die for. I forgot how much engineering Dell dumps into their systems. It’s so nice. Thank you!
Nice Server. Well done!
Check your PCIe Cards IF the Airflow works OK - Rackmount is optimized for high Front-to-Back Air, and sometimes Heatsinks are different or rotated to account for that, Fan Inlets etc as well
This is such a great video ❤
Y’all are being so nice today!
Was this a good deal or not? What would you get instead?
Helped a friend build out a MI lab box using one of these as the base as it was ridiculously cheap for what it was at the time. I think 799 from Met Servers and they only had a handful of them. Found them originally as they needed 2-3 2 slot GPU support and had a rack. Seems they completely dried up supply wise, but I have found a few places listing them for $799, just never any in stock. Great price compared to R740 machines which just now bare bones configurations are getting down to starting in the 800-900 range. By bare bones literally just case, board, heatsinks and maybe some caddies. Wish I grabbed one of these when I had them order there's.
Yeah and the funny part is it’s the same damn hardware as the R740
@@SPXLabs 7920 towers are still available. Not the same storage options, but still the same boards and GPU compatibility if you were doing an MI box. Also cheaper at 499 bare bones. You can covert them to rack as well. Just limited to 4 bay for the most part, plus add in PCIe storage. I've seen you can do them as 8 bay, but haven't found anything concrete on how.
I’m pretty sure the workstation towers can hold 12 drives plus 16 PCIe NVMe drives. Pretty sure
I know a friend who bought used DELL gear like this. Saved a tone of money over buying his own case and building a server from scratch. If it were not for me having unused components around, I would have probably have done the same but then I would also have to take into account the noise factor these DELL servers generate and that means having a dedicated server room / area.
Yeah huge trade offs all around. Turns out that my Eaton UPS are louder than the R7920 and I don't know how I feel about it lol. I didn't think I would get back into a Dell system after being annoyed about noise but here I am.
@@SPXLabsIf you really want too, I guess you could tweak everything and install your own NOCTUA fans in there. I've seen various videos of people slightly modifying their DELL servers to do that to make them more "HOUSE NOISE FRIENDLY". But then again, if your EATON UPS is louder, who cares right? Your servers are in dedicated "rooms" anyway.
@@ptessier73 Naw, everything is fine. Although I am tempted to maybe do some sound dampening in the future for fun.
Hello, I'm looking at upgrading from a T7910 to a T7920. I noticed you're planning on using the Dell Quad NVMe PCIe adapter, and so am I. I wondered how to set up RAID for the four m.2 cards. (I'm considering Samsung cards (2TB)). Can you discuss this in the upcoming video and include your recommendations on the m.2 cards (manufacturer, size, etc.)?
Plus, I'm wondering about the ability to use the eight drive bays with RAID. Finally, in your earlier diagram, it should have the ability to have up to 136TB. How does one accomplish this feat? I've seen Dell sell 6TB SAS individual drives, but nothing can reach 136 TB. Please cover this, too. Thank you,
It's hard to say if you would actually say power but not having a graphics card because you have dual power supplies running. Although if you unplugged one of them, I guess technically that statement with people are accurate on saving power, but that's the whole point of having dual power supplies is having the dual redundancy and stability
Yeah I guess it really depends on how everything is configured
What is it the PCI express card between Nvidia Quadro P4000 ( short PCB and be lack plastic end for fan) and Dell 4*nvme drives ?! Ot has a aluminum black backplate...
Always interesting to see the hostnames of used servers. Seems it was a NASDAQ server if you look at the hostname at 3:32.
I wonder if it was actually used for trading or if they just named them like that. I wonder if they have S&P500 also.
Got a R620 with a Yahoo asset tag on it once right next to the service tag pull out. They went cheap with a 4 bay unit.
Oh nice. Perhaps they didn’t need the storage?
My PowerEdge R720 came from USC college.
That’s pretty cool. Any custom paint?
Hello
Please share the video on how to replace the memory cards
Mine doesn't have memory card slots, so I can't help you :/
I have had R series WS's since the R5400 and onwards. Still on an R7910 and have a few of them, others just being what they actually are, servers. The R series are just their server cousins with some slight changes and different BIOS.
Wow nice. I prefer the workstation BIOS I think. They seem to work more simply for GPUs I feel like
@@SPXLabs LOL, careful though, the R's have still had their share of noisey fans from GPU's and other PCI cards being installed and BIOS sends fans from ground-idle to take-off power. You will in cases with big GPU's have to move the fan speed offset to move more airflow.
The thing with these is though, they are not designed to sit and a desk with the operator, they are designed to sit in a server room/rack and have things like PCoIP or remote video/USB extension. Doing soo keeps noise and heat as well as physical access to the machines away from the human.
Typical. I wish they never screwed up idrac and removed the ability to control the fans more perfectly. I got a dedicated room but it’s not perfectly sound insulated so I can hear it but right now it’s not too loud. Currently, no GPU required but we will see lol
@@SPXLabs If no GPU or PCIE cards added in, that rig should quieten down to barely audiable. You still have fan control in BIOS just have to hunt for the settings that have different names and several spots they hide.
True but no like the hex codes you could send for absolute perfect control like in the past.
Just curious if there is a noise difference between what you demo'd and the tower 7920. I have an old SuperMicro 4U (Ivy Xeons!) server rackmount server in my basement hanging out in the furnace room. As long as you don't hang out in the furnace room (rarely go in there), it's not too bad. Prior to that, I had an even older rackmount server - the fans on it were crazy and could be heard throughout the house. Anyway, I'm assuming the tower station would probably be a lot quieter.
The tower version is definitely more quiet. The tower is whisper quit. I wouldn’t want to sit next to the R7920. Can’t hear the R7920 throughout the house when it’s in the server closet.
@@SPXLabs if you put the psus in non-redundant mode it will quiet down a lot, that's certainly the case on my R730/R7910.
The other thing is to turn off the 3rd party pcie fan mode, which sends the fans crazy if it doesn't recognise pcie cards like consumer GPUs
That’s good to know. Thanks for dropping the details. Right now with Red Hat installed its more quiet than any previous racked server from dell I’ve had.
wish i could upgrade to this!
This thing has been absolutely rock solid. I feel like I’m wasting its potential on running essentially nothing
@@SPXLabs Would be tough to find workloads to use it to its potential for me aswell. I am still running a hpz440 for a homelab server. So i am due for an upgrade.
Dell no longer sells the rails for the tower. I tried to order them 3 months ago and was sent the wrong rails. When i spoke to customer service, they suggested that they don't sell them any longer, at least in the US. I would love for someone to tell me I'm wrong and point out the correct rails in stock. somewhere.
Hang on a minute. For real? I haven’t heard that yet but I have also never attempted rack a tower server except on shelf rails
I would love to know how loud it is. The reason I ask is I'm currently running an R720XD in my rack. With blue iris as the only service, its desktop quiet. Due to the space constraints of my home, my 25U rack is in my office. I was contemplating putting a graphics card in my R720 but I was concerned about the fans ramping up and becoming to loud.( I keep the fan curve at stock settings) What I'm hopping is with an R7920, the addition of a graphics card will not cause the fans to go ballistic.
The addition of a graphics card doesn’t make it go ballistic. Right now it’s more quiet than my UPSs surprisingly. If you stay tuned I’ll be sure to get a video up giving better detail of how loud it is. Just don’t hold your breath. It’s the holidays after all
@@SPXLabs Any word on when that R7920 update video is coming?
I'm really interested in the noise aspect.
@rdsii64 ooops I forgot. Good reminder. I’ll try and knock it out this week in like a UA-cam short
@@SPXLabs Thank you.

A poweredge withou paying full poweredge money
Yeah basically. Really bizarre that they both exist with the same hardware too. But different bios
@@SPXLabs been considering one as it's a cheap way to build a cluster instead of R740s
@JimtheITguy similar boat man. Looks like the towers went down in price but they are pretty big. Although the 7820 tower has the same hardware and is cheaper
