Doug,
AMASS is a product of Advanced Archival Products, Inc. It is
a UNIX filesystem designed for optical and tape jukebox systems.
It can handle jukebox configurations of virtually any size. We
have installations ranging from stand-alone optical drives to
9 Terabyte tape jukeboxes.
AMASS is implemented at the VFS and is designed to provide a single
filesystem (single device) view of one or more jukeboxes. This
overcomes the typical limitations imposed by systems implemented
as a filesystem per side of optical media.
Files and directories can span media boundaries.
One mount point.
One filesystem to administer, etc...
AMASS uses a magnetic disk cache to support data caching allowing
read and write caching to eliminate jukebox thrashing. In addition,
the primary meta data is also accessed from magnetic disk allowing
trivial meta data operations such as cd, ls, find, ... to
function without creating contention and jukebox thrashing.
To address your questions specifically, we do not have experience
running the product under AFS. I am not familiar with the /vicep
filesystems referenced in your document. I would be happy to review
any information you could provide.
Since AMASS is its own filesystem, and since there are no filesystem
size restrictions inherent in the VFS or AMASS, the 2GB filesystem size
limitations typical of other filesystems has not been a problem to date.
The only limit inherited from UNIX is the 31 bit signed offset which
limits file sizes to 2GB.
If you have any questions, please feel free to call or email them. We
have had other inquiries relative to AFS and would be happy to help
you determine if this will work for you.
