Panasas Parallel File System and RAID
In this video blog post, Garth Gibson, Panasas founder and CTO, talks about file system RAID and how the Panasas parallel file system, PanFS, provides redundancy as part of the file system itself. He compares this innovative approach to most parallel file systems which push reliability down to the storage device layer, usually to hardware RAID controllers. Watch Garth as he explains the problems with the RAID controller approach to redundancy, which include: cost and long reconstruction times. He concludes by talking about the various technologies essential to making reconstruction as parallel as are applications.
