mhddfs & GlusterFS

I haven't posted any links for a while.  They've been piling up.

There's a FUSE plug-in for Linux called mhddfs that aggregates storage devices into a single virtual filesystem.

I'm thinking I'd like to use a SATA port multiplier to pull together a bunch of drives.  (Such as those made by DAT Optic.)  Unfortunately, that system wouldn't have any redundancy, although one could still copy to individual drives manually to establish multiple copies.

I also found reference to a distributed filesystem called GlusterFS that appears worthy of further investigation.

Addendum: SATA-IO has an article about port multipliers and the difference between implementations, i.e. command-based switching (CBS) vs. FIS-based switching (FBS or just FIS).
