This article is from the storage FAQ part2, by Rodney D. Van Meter with numerous contributions by others.
Metior (pronounced like meteor) is targetting an incredibly broad market, from laptops with removable media through supercomputers, with prices from $650(!) to $118K. They handle multiple coordinated copies, so off-site backup can be automatic. Can do migration for client machines (with appropriate software licenses and changes to the file system). The hierarchy seems to be extremely flexible, variable on a per-user or per-group basis. Machines without client licenses can mount the Metior FS using NFS. Runs on Suns, SGI, and HP 9000/700. ANT is new, and they've only got a handful of customers so far, but it looks very interesting.
