Will ARM CPUs becoming more popular, and good motherboards being available for Ampere Altra It would be awesome if Unraid 7.x would have ARM support. 

 

I currently have the legacy pro license but I'd be willing to pay for a new Lifetime license if that meant I could get ARM support. 

+1 to buying a new license for this. I would like to run unraid on an M4 mac mini actually.

I suspect this is unlikely as Limetech have years of roadmap items left to do on the x64 version. Be nice to e proved wrong though.

I dont suspect that ARM support is anywhere on the roadmap, but even if it were running unRAID on an ARM based MAC is unlikely. So far as i know the one project trying to bring linux to apple silicon is only up to M2 chips and progress is slow.

Would be nice for future builders to have arm bases like https://radxa.com/products/rock5/5itxp/#techspec

Kinda pointless when you have comparable boards with x86 CPUs for similar prices... and where you won't run into issues like half the containers you might want to use not supporting ARM.

I too would like to see arm support but that would double the applications that are currently used in the bzroot route system that is implemented in unraid.

This would also require an almost complete emHTTP rewrite. It's not all commands are universal and there's a lot of differences between the arm chips, the arm processors, and the kernel that is compiled with unraid.

And has to start with recompiling the arm drivers within unraid and even then it would be select arm devices like known devices like pi.

I'd love to see SOC arm boards so that I can put unraid on things like unify UNas.

This was explained and shown somewhere on the forum earlier where they attempted and looked and where arm wasn't maintaining as there's too many weird socs that require third-party drivers and it was not worth the 1% of users or attentive users of hardware when the colonel didn't support half of the arm systems and the repositories for slack, Linux were lacking arm.

Now after some repository, edits, updates and third-party systems of been maintained. The issue is now that the applications that would run for x86 are not the same for arm and how they are processed, which changes how the emhttp and unraid services would have to work.

Which if they did fix the web page system would guarantee to double the installer size for USB to be able to support both x86 or arm.

So maybe in the future a branch for arm only and a branch for x86 64.

That way the systems are universal between each other but not the same software stacked to maintain.

And even then that will require a second r&d and other from limetech. Given the reasons, key change and other structure change for the company, this is going to be way off in the future. I can see this being implemented 5 to 10 years from now and even then it would be the groundwork not a full polish system.
