Slice of Raspberry Server. BladeRunner v0.3. Test

Slice of Raspberry Server.
BladeRunner v0.3.
Test part of the future enclosure for CM4 based blades (Uptime Compute Blades). 20pcs. at the moment, up to 22 in the future.
Each one has:
- 1Gbt Network
- PoE
- 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU
- up to 8Gb of RAM
- up to 8Tb NVMe storage (theoretical, but 1Tb works great)
- Real-Time Clock (RTC)
- power consumption only about 6W

I finished building and testing my "blade" v0.2. Server-oriented board based on Raspberry Pi CM4. Up to 22 blades in just a one rack unit (1U).
Each one has:
- 1Gbt Network
- PoE
- 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU
- up to 8Gb of RAM
- up to 8Tb NVMe storage (theoretical, but 1Tb works great)
- Real-Time Clock (RTC)
- limited debug functionality (UART, USB, test pads)
- microSD card
- USB port (with 5V in)
- power consumption only about 6W
This board managed to set a new record for the storage speed, which by more than 10 percent faster than the second place (the site with tests is storage.jamesachambers.com).
It has been working in a production environment for more than a week, along with a Raspberry Pi 4 cluster, with no issues.
Next plans: v0.5. And schematic finished already. It will have everything you need for initial setup and debug any software issues.
This will be my first commercial project, and I'll go to Kickstarter with it.
Wish me good luck 🙂
Please write it would be interesting to use such devices for a home cluster or at work?

CM4cast concept
- USB-C (power, HDMI, USB)
- Full-size HDMI
- mSATA SSD
- Super Compact: 6*6*1.1cm
Up to two 4k screens. Nothing extra
Based on Raspberry Pi CM4:
- Wi-Fi 2.4 GHz, 5.0 GHz
- BT 5.0
- Quad-core CPU Cortex-A72 1.5GHz
- up to 8GB RAM
- H.265 (HEVC) (4Kp60 decode)

I am planning this device as a replacement for Chromebit in the first place. It can replace Chromecast and Intel stick in some cases.

"blade" v.0.1 results for CM4 platform: ✔️ PoE

"blade" v.0.1 results for CM4 platform:
✔️ PoE works
✔️ UART works
✔️ SD card works
✔️ LEDs work
✔️ USB 2.0 interface works
✔️ NVMe works
✔️ RTC (Real Time Clock) works
✖️ The network doesn't work and there are two PCB mistakes.⠀
Easy to fix. v0.2 is under development.
That will be a server 1U height only. With up to 22 Raspberry Pi CM4 (up to 8Gb each) and 22 NVMe SSDs.

I've already seen this cube in the feed several times. And I decided to model and print it.
The model is available on the Thingiverse website (you can find me there by nickname "merocle")

I got some parts for the project.
That will be 1U server platform for up to 22 blades with CM4 and NVMe SSD each.
🔸SD card - because eMMC is not reliable and not easy to set up from my point of view. And probably they will add NVMe boot one day.
🔸UART0 - for debug, alternative to USB and HDMI (okay, you need to add one line to the config file)
🔸USB port - for debugging and copying files if needed.
🔸PoE power - I'm sure that PoE switch is better than a custom backplane.
🔸RTC clock mounting place - if you need a real-time clock you can install it
🔸"Half-rack" option

Raspberry Pi 4 with 3GB of RAM. Guess I’ll start

Raspberry Pi 4 with 3GB of RAM.
Guess I’ll start from the beginning. I really wanted to test Raspberry Pi CM4 8GB for one of my projects.
As it’s very hard to find it available in stores (at the beginning of 2021), I had to do it myself.
As a donor, I took Raspberry Pi 4 8GB because the 8GB (64Gbit) chip is hard to find too (by a piece, I mean; if you need 1000x, then it’s possible to buy).
I managed to solder the memory from the Raspberry Pi 4 to CM4. And I decided to experiment a bit.
Unfortunately, 16GB chips are also not available by a piece. But I managed to buy 3GB chips.
Raspberry Pi successfully started with the chip MT53E768M32D4DT-053 AIT:E
And it shows me 3GB at the start. Now I have a really unique Raspberry Pi 4 with 3GB of RAM.
But the system shows only 856MB of RAM available though. I even tried to solder the chip again, but the same.
So… You can call it a failure. But nevertheless, I think the whole project was a success. Memory passes all tests. I got a lot of experience. And perhaps with a firmware update, Raspberry will see 3GB, or I will solder 8GB or even 16GB chip one day.
By the way, I used a cheap Lukey 702 soldering station. And a timer to follow temperature profiles (I have read about it on the internet). To be honest, this is my first reballing experience.
