Odroid H4 🎉

 

16th April Hardkernel announced 3 new Odroid models! See https://forum.odroid.com/viewtopic.php?f=168&t=48344 | https://wiki.odroid.com/odroid-h4/start

I appreciate that they listen to user needs and new models are improved based on the user feedback!

especially 2 models are very attractive: H4 Plus and H4 Ultra (with 8-core Intel N305) are interesting because they have 4x SATA III, 1x m.2, 2x LAN (2.5Gbit Intel I226-V)

there is also kit for converting to mini-ITX format ! https://www.hardkernel.com/shop/h4-mini-itx-kit/

10x SATA you can have with m.2 to 6x SATA ASM1166 controller

For me, the H4 Plus will be enough, it has Intel N97, which is better than very popular N100.

 

I need to highlight an awesome work and focus on idle power consumption.

Only 2,7~2,8 W ⚡️ (on the DC side, so potential inefficiencies in the power supply are not taken into account)

In this test, Ubuntu Desktop OS was used, and we think that power consumption could have been slightly reduced if Ubuntu Server OS had been used.

 

This will be most probably my main home server / NAS.

❓Anyone with Odroid H4 Plus / H4 Ultra here?

 

I have one H4+ but I don't plan to have my unraid server on H4+ because I already running unraid on older model H3. However I can sometime test unraid on H4+ and do some power consumption measurements, like with my H3 here: https://forums.unraid.net/topic/11386-whats-your-power-consumption/?do=findComment&comment=1404417

They have added support to ECC (in-band ECC) with new BIOS:

Hi! Is there an update? I already use a H2 plus with proxmox and pfsense as VM and some lxc (nginx, technitium, searxfs, apt-cacher-ng, gitea and omada) and it only needs 7-9W in idle, if I use my 100MBit internet line it is about 12W. An incredibly good machine. The same constellation on a Lenovo M920x Tiny or similar requires 15-30W.

Now I want to update my unraid machine as well. currently a 10 year old fujitsu serverboard with a xeon is running at about 18w idle (hdd in spindown), I want to get it down to 5 w. I have 2x 22TB HDDs and 2x SSDs. The odroid h4plus (N97) or ultra (N305) would be perfect.

Does anyone have one of the two and can say something about it? they are not cheap. with RAM and power connector 400€ or 540 €....

I have Odroid H4 (not Plus)

also I have 2x2 card - for 2x m.2 SSDs

Without 2x2 card (1x Samsung 980 Pro 2TB)

• ...

With 2x2 card + 2x m.2 SSDs:

• ...

BIOS: - version: 1.08 for 2x2 card
      - ASPM enabled
      - IB-ECC enabled
DISK: 2x m.2 Samsung 980 Pro 2TB
RAM:  1x DDR5 32GB Crucial
ETH:  connected to 1Gbps switch
OS:   DietPi (Debian 12)
      Kernel: 6.1.0-37-amd64 
      Packages: 262 (dpkg) 
      CPU Governor: powersave

It is not unraid, but DietPi (Debian) but the results should be very similar with unraid.

• on the left side, you can see logged power consumption (from Riden RK6006) every 0,3 second

• when running htop you can see slightly higher power consumption compared to total idle.

All with enabled IB-ECC.

Thank you! This is unbelievable low. I appreciate the efforts of hardkernel to design/make the power consumption as low as possible for their hardware. Unlike the other cinese brands for n100 boards.

But I m worried about higher odroid models like plus and ultra with higher processors, not in deep idle, but under a bit workload.

A lenovo m920x with an i7-8700(? I have to look it up in my cellar) needs without attachments 3w idle with debian headless, but consumes with some services 15-30w with middle regular load. My odroid h2 needs 7W with middle load for the same. I think it’s because of the processor.

My unraid on Odroid H3 (with 1x. m.2 SSD, 2x SATA SSD and 2x USB flash drives) and running some docker containers:

running containers: immich_redis immich immich_postgres14 scrutiny PortainerCI

has real consumption ~ 5 Wh from socket, see details in my post: https://forums.unraid.net/topic/98070-reduce-power-consumption-with-powertop/page/28/#comment-1363492

I think Odroid H4 / H4+ will achieve very similar or better results (newer CPU has better efficiency). But remember H4 has ~0,5 W less power consumption compared to H4+ due to missing SATA ports and 1 ETH port.
