Using porn to recover a RAID 5 array (Talk from Defcon 17)

[Rajahal]

This is a pretty fascinating talk on how to use porn (or any images and sounds) to guide you in recovering a RAID 5 array with more than one disk failure. Naturally, none of this applies to unRAID, but I think it does a good job of explaining the concept of RAID 5 (and distributed parity in general) in a visual and easy to understand manner (assuming a certain level of geek knowledge, of course). Pretty fascinating to see the actual striping structure of RAID 5 show up in garbled images!

 

 

The talk is 48 minutes long. Feel free to skip the intro stuff about other RAID types (start at about 27 minutes in), or skip to the live demo (start at about 37 minutes in).
