Sector/Sphere: High Performance Distributed File System and Parallel Data Engine

Sector is also a member of the Open Cloud Consortium:

One caveat: Sector/Sphere is not used by anyone (notable) in the industry. I hope they become a viable alternative to Hadoop as they do have some strong points on paper.

OTOH, an industry maven told me recently that "they don't listen" (to industry feedback), which I hope, is not entirely true.

A lot of interesting and bold claims. Has anyone played with this product? Does it actually work well?

I'll be spending some time on this.

Glusterfs, Hadoop, Pohmelfs, there are a lot of interesting developments in this sphere.
