Stop right there. RAID has nothing to do with cryptographics. The softraid(4) driver can do some things which provide software RAID capability, and it can also conduct cryptographics.
RAID stands for Redundant Array of Inexpensive Disks, or Redundant Array of Independent Disks. It was devised at the University of California, Berkeley. As initially concieved, there were a number of different methodologies devised, and assigned a series of different numbers, such as RAID 1 (mirroring) or RAID 5 (parity data interspersed with user data). This even included something they called RAID 0, which has no redundancy capability at all, and should have been called "AID" instead of "RAID". See http://en.wikipedia.org/wiki/RAID for details.

But yeah, softraid(4) is supposed to be a better replacement for the RAIDframe driver, with a uniform set of utilities shared between it and hardware RAID drivers (..bio(4)/bioctl(8)).
EDIT: I had a erroneously stated that RAID0 was equal to JBOD, this was wrong.. apologies. Last edited by BSDfan666; 23rd September 2009 at 06:53 PM. |

Eventually, BSDfan. We have different opinions about the state of softraid(4);

My opinions are based solely on speculation, I don't use disk arrays.. so I concede to your experiences on the matter.

I know, I thought I mentioned that I am not experienced with RAID though.

It would also be worth your time searching through the misc@ archives for related information. I recall that Marco Peerboom has stepped a few people through configuration issues within the last year.
