When we're buying the parallela cluster kit, it comes with a 16 GB microsd. Can we change the microsd size, or can we upgrade it later on easily? It'd be nice to have it as large as possible for my project. Would it be possible to make options as this configurable in the shopping page? If I got 16 such kits, they would make 1024 cores and just 256GB disk, which is probably not enough for the data-intensive compute tasks I'm considering this hardware for. Well, it's some proprietary parallel data mining algorithms, basically.
The 1GB RAM limitation per board is also a bit challenging but that's not drastic.
