Feature requests for HC3 (wish list)

Unread post by larstobi » Wed Mar 18, 2020 5:12 pm

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.
