Rack mount case would be nice.

#32Outside of doing it for the heck of it (which is a valid enough use case , IMHO), what practical use do you see out of this ? To me, it looks like I can do all of the same things mentions (perhaps even waay faster) on a x86 processor in the same size factor.
Re: Show HN: Turing Pi 2 – a compact ARM cluster with 32 GB RAM
#33Besides academic uses to perhaps teach distributed systems on these are there any real world use cases for these clusters?
Main use case might be doing whatever you would do on 10 year old laptop reused to be your home server. Similar performance, similar power usage.

So your question what's the advantage of cluster comparing to one processor unit?

#35Forgive me if this is a stupid question; but I see that it has SATA support. Does that mean this can be shoehorned into NAS service?
I have an irrational desire to create a cluster, but I would like to use it for something practical like a NAS. Bad idea?

You can. Why not?

You'd be hard pressed to find an old laptop with 32GB of RAM, and a laptop doesn't provide the same operational conditions experienced by a cluster of 4 computers communicating over a network connection.
Scaling horizontally presents entirely new classes of challenges that aren't experienced while scaling vertically.

A considerable amount of people is already assembling and running clusters of raspberry pis, including hosting companies. A cursory search through eBay or Amazon can provide you with an idea of how many people are already operating these small clusters and spending money on this sort of setup. I'm sure there's a significant demand for a COTS cluster solution that allows people to avoid having to MacGyver their own cluster just to get Docker Swarm or Kubernetes running on a small cluster of raspberry pis.

You could get an off-the-shelf x86 machine in the same form factor and run the cluster nodes in VMs, for instance.
Maybe you could argue that four RPis on a network are more reliable than a single x86 with VMs, but that doesn't seem to be the point of this machine.

Couldn't you buy four 10 year old laptops?
