Feature requests for HC3 (wish list)

Post by larstobi »

I'm enjoying my stacks of ODROID-HC2 very much. :) It's a great platform for building highly available and highly performant storage clusters for the home.

Pros (keep doing):
  • Stackable
  • Low 54 USD price per HDD slot
  • High throughput with 1 Gbps per HDD
  • Horizontally scalable storage (with the right software, i.e. seaweedfs, ceph et.al.)

Cons (improve upon):
  • 32-bit CPU
    • Low bariety of OS support (not that many distros makers release ARM 32-bit Linux distros)
    • No OS with atomic updates supports it (i.e. Fedora CoreOS)

3 things missing to make it even better:
  1. ARM64 CPU (Would open up OS support to Flatcar Linux, AWS BottleRocket, Ubuntu Core and soon Fedora CoreOS)
    • OS-es with atomic updates eliminates partially completed upgrades and lowers the consequence of broken upgrades, and eases the burden of patching large amounts of machines.
  2. Power over Ethernet (PoE) with IEEE IEEE 802.3bt support for single cable attachment.
    • With built-in support for PoE we can basically just attach the Ethernet cable to the ODROID-HC3, insert the MicroSD and HDD, and be going.
    • WIth a PoE managed switch we also automatically get remote power off, on and cycle, one of the most used features of BMCs on enterprise server boards.
    • Lowers the price per HDD if you've already got a 802.3bt capable PoE switch.
    • If the board with the HDD attached consumes less than 24W, then IEEE 802.3af PoE support is sufficient.
  3. Network bootable with PXE boot.
    • Can eliminate need for MicroSD card to boot (less cost)
    • Will spend less time flashing MicroSD cards for new boards

Adding those features will increase the cost a bit. The future Kobol64 product (https://kobol.io) comes out at a cost of about 65 USD per disk slot (295 EUR / 5 slots, converted to USD), whereas the ODROID-HC2 costs 54 USD per disk slot, so there is still a possibility to beat that price point. For ODROID there's no need to spend time creating a 5-slot cabinet, just develop a new board, keep the HC2 aluminium frame and ship it. :-D

What do you think? Am I barking up the wrong tree? Let me know in the comments below.

We will consider the suggestions. But we have no firm plan yet.

I would totally agree with this.
The only thing, the more RAM the better. A 4Gb and an 8Gb option. 2-4 cores totally enough. Higher clock rate is better than more cores.

Fully support this as well! Big upvote! Given the drop of support for 32bit with glusterfs, the HC3 (especially with these features) would be a perfect fit. For a cluster, it seems like there will be relatively large demand for this hardware in the niche space.

If not HC3, is there something similar in the works for the near future? I'm looking forward to it and if not I'll have to buy something else, but would prefer odroid!

Thanks!

I love the HC2/HC1, I have 5 at this point.

For an HC3 my biggest wants would be a 64bit cpu, multi-gig 2.5g ethernet and POE support.

More-or-less my wishes as well + USB3, from a very satisfied owner of HC2's.

seeing posts or raspberry pi 4 with 4gb ram doing ceph cluster, it would be very awesome to see 4/8gb ram HC3 with 2.5gbe and POE

Not sure if 2.5G is doable with current socs. They usually expose 1G eth via soc pins, and need only a phy. H2+ uses pcie as a bus for network, while most arm socs don't have pcie internally (or have only one)

I would like to add a humungous +1 to this thread. The addition of 64-bit ARM + PoE would be an instant purchase, at least 5 to start. PXE boot, eMMC option, and 2.5GBe would be icing on the cake if possible. I'd be ecstatic.

Why PXE boot if it's designed to hold a HDD?

The minimum order of 5 is a hint ;)

Good support by the mainline kernel would be very nice. XU4 platform has had its issues with that over the years, from what I've seen.

I'd like a better stackable heat sink.

Due to heat rising, the topmost drive in the stack is several degrees Celsius warmer than the bottom drive.
Perhaps increasing the spacing between drives (heatsink is taller) or adding more surface area can mitigate this.

Also, it would be nice if the heat sink's corners aren't as sharp as they are. I'd dress each corner with a file just before anodizing; it doesn't have to be an actual machined radius.

I'd also like it so the microSD card doesn't stick out to where it can be easily broken off.
