Level Up Your Homelab With The Raspberry Pi CM4 Compute Blade

Today we’re taking a look at the Compute Blade, a rack-mountable PoE carrier board for a Raspberry Pi Compute Module 4. These are designed to allow you to stack up to 20 blades, each carrying a CM4 module, into 1U of 19" rack space. So you’re able to create a low-profile cluster with 80 ARM cores, up to 160GB of RAM and up to 160TB of NVMe storage.

Now I want someone to make a clear acrylic rackmount case for 20 of these!

Interesting and thanks for doing this. Your case is great. Its still very frustrating that its so hard to my RPi in Q1 2023

[@disasterincarnate]

always like the variety of CM4 related products that spring up, but am still confused why more appear and are advertised to home users when none of us can even buy them any more, their always sold out.

[@kobs9636]

and over priced.

[@ReganMcCullough]

right? This project looks awesome but procuring a CM4 is much too difficult. It sucks, I feel like we'd have more ideas produced like this if there was better availability

[@xanderplayz3446]

At least the pi shortage has cooled down now.

[@Bianchi77]

Nice video, thank you for sharing it :)

[@peteradshead2383]

if only we could get a CM4 anytime some.

[@the-real-random-person]

NICE so cool!!

[@jumpmaster5279]

This can be a potential design for Linux ultra mini pc

[@NeseComedy]

This would have been amazing back when the CM4 was cheaper than the RPi 4

[@kingtungstenworldwide4472]

I hope this isnt a silly question, but could this make a great NAS server, versus the larger NAS servers for home use & editing? SInce the ones I have from WD & QNAP are only for HDD drives, having a low power Raspi version with NVMe drives would be a game changer.

[@MichaelKlements]

Yes, you could definitely use this as a NAS running storage on the NVME drive.

[@fedyaf2710]

You don't get all advantages of NVMe drive with basicaly mobile cpu

[@-Tholos-]

I assume you only have one but I would be really interested in temperature with two blades in the case.

[@MichaelKlements]

Yes, I only have one. I doubt that it would make more than a one or two degree difference. There is quite a lot of room for airflow over the heat sink, even with two in place.

[@siddharthchordiya]

Any thoughts for a detailed Clustering Video
How to Do ?
Where to Start?

[@MichaelKlements]

There are lots of good clustering videos available on RUclips - Network Chuck has a good one on clustering Pi’s using Kubernetes

[@siddharthchordiya]

@@MichaelKlements Watched that whole video but didn't understand a thing but was fun to watch
What I am looking for is an In-depth introduction series with tutorials and explanation and not in an whole video but as a Series of multiple videos if possible

[@anandmoon5701]

So the blade is powered via POE module.

[@MichaelKlements]

Yes it is powered through onboard PoE

[@davidhilsabeck]

I am pretty much ignoring all things Raspberry Pi until stocks are available. Not holding my breath.

[@haydenc2742]

1st! Very very very nice!
These are so cool...just wish RPi had more chips so they could sell em at their recommended price not 5X the cost
Jeff Geerling does a TON of video's on these too!
Keep em coming!!!!

[@Marthisdil]

not 1st...5th ;)

Hi Micheal, I saw your previous vedio that Make a Simple arduino energy meter. In that i have done query that unfortunately all the reading in the lcd shows zero only, even though i apply the load. What is my mistake, pls help. I am using the same Ct talema ac1030. And I checked the code for KW and I am getting Maximum of 6663 W. Is it the maximum limit or somewhere I am doing any mistake. ruclips.net/video/W2Pa91I6QuY/видео.html(This Was the link of That Vedio)

[@the-real-random-person]

I already see my next 63 slaves k8 kluster fr

Looks like a uni students project like your monotone voice haha!

"The reason CM4s are unavailable"

[@RinksRides]

Dunno where you got all those cm4's, but your wasting your time. Risc-V FTW.

[@niceride]

Which carrier boards would you suggest trying the Milk-V CM on?

[@Berlinticket]

hot shit👊
