Mini-ARM cluster

I currently don't have a server in my Sydney apartment, sure I've got a Raspberry Pi doing a few minor things (Radius, syslog, NTP, DNS), but those are all for my network devices, I don't use them directly.

What I'd love to be able to buy is some form of mini-cluster, probably in the form of a 3ish RU rackmount device that has a gigabit ethernet switch as a backplane, and lets me slot in CPU blades.

Ideally I'd want two kinds of blades, the first being ARM64, with as much RAM as parts will allow (8-32GB), and two disks (allowing a mix of spinning for bulk, and SSD for speed). These would mostly run something like OpenShift.

The second set of blades would be standard Intel i7, again with as much RAM as possible (32-64GB), and the same storage as the ARM's (or external) to allow VM's where I can't just run on ARM.

Obviously there'd need to be some form of self-backup, and ideally the cluster admin role could automatically failover between nodes as needed.

With something like this I could deploy it at the three sites I've got servers, allocating an IPv6 /64 to each site, which would let every instance have static addressing and just migrate between nodes.

ARM64 systems have been talked about, but I've yet to see a serious design that isn't a dense cluster, only useful if you've got hundreds of nodes.

Wasn't there something on slashdot last year about an all-in-one that does that? Also a guy I have been meaning to introduce you to has something very very similar as a project. I really need to get you two talking when you are down here.
