Also, isn't RAIN basically an array of RAIDs ??
No, that would be Network RAID.
That how would you define RAIN? Wouldn't each node be a NAS of some sort, and more than likely that NAS would be configured with RAID, or am I missing something?
It depends. RAIN is a blanket term for a lot of things, unlike RAID which is quite specific. You could make a great argument that Network RAID is a member of the RAIN family.
But in general terms, if you use Network RAID (treating each node as a disk) it's not called RAIN.
RAIN is assumed to have nodal awareness. RAID treats all members as drives and can't tell what is a node, and what is a drive.

What type of system would be a good example of RAIN? Gluster? Ceph? or am I totally missing the boat?

Yes, Cluster, CEPH, SCRIBE, Exablox... all RAIN. Traditional RAIN by everyone's standards.

I'm familiar with Gluster and Ceph. Exablox is not open source...
SCRIBE is done by @scale -- so it's not open source, right?

Well, I think you guys really RAIN'd on this guys parade. Good work.

Correct, it is closed source.

You were hoping for a RAIDing party?

@scottalanmiller With this group? You're just spinning in place.
