I have been toying with the idea of an open source project to achieve a
more generalized functional spec. than what symform has created. I was
thinking of calling it RAINcloud (redundant array of independent nodes)
I started drawing up the requirements over the holiday weekend.

symform, a startup create 32 parity stipes of 64 original stripes, and
distribute the fragments in different geographies.
they call it, RAID-96 And apparently reed-solomon coded.

As far as i know, theres not support for this, however, i do believe
raid6 uses reed-solomon.

I was wondering if there is support for a raid level where one can
choose the redundancy level. Raid 5 allows for one redundant drive,
Raid 6 for two, but there's no raid level that would support arbitrary
redundancy (even to the point of allowing one to add extra redundancy
later on, by simply putting spare drives to immediate use).
I'm just a casual Software Raid user, and have been using Raid 6 for a
small 8 TB array for a few years now and I realize that there's quite
some CPU overhead involved for such redundancy, but for my purposes
speed is not a relevant concern (10 MB/sec is enough).
