Why the SMB Still Needs Hardware RAID

@scottalanmiller said in Why the SMB Still Needs Hardware RAID:
The most common RAIN approach that I see is taking all disks in the pool, noting their nodal presence and using mirroring to distribute the data so that data mirrors never go to the same disk and/or the same node. So a little like a networked RAID 1E but with more flexibility and the option to add nodal separation and performance testing so that data moves to where it is used.
Ok that makes sense.. thanks.

Are you aware of any open source RAIN systems?

Gluster and Swift

I think Ceph and Lustre may be two others.

Lustre is RAIN, but is closed. Gluster was the open replacement for Lustre.

Just a quick search showed that Lustre was GPL 2.0, not sure if that is new or not.

Oh wow, must be new. It was crazy expensive in 2006 when we were really investigating it. That's awesome.

Ah looks like it went open source in 2010.

Oh cool, so I remember things well then. I'm just out of date. Gluster probably forced their hand, why would anyone consider Lustre when it was closed source? The answer was probably... they wouldn't and didn't.

Yep, I'd assume that was the case. Especially when it is a such a specific, and at the time, niche market.

And when Gluster went directly after them, even in name.
