AMASS Overview
bar code
An array of spaces and vertical bars in varying widths in a
BFS
Bitfile Server component of DataMgr. The BFS maintains storage policies, assigns bitfile IDs, and manages the licensing of clients.
bitfile
Bitfile identifies the contents of a migrated file on DataMgr. Bitfiles are never modified. If the original file is subsequently modified, a new bitfile (as well as a new bitfile ID) is created when the file is remigrated.
bitfile ID
DataMgr assigns each migrated file a unique bitfile ID. The bitfile ID is never changed and is never reused.
C
cache
All data flows into a central cache located on the UNIX server before being read from or written to media. By using the cache, AMASS allows applications to read and write at hard disk speeds, and to access the library only when the requested data is not in the cache. See also striping.
cleaning group
A special volume group that contains drive cleaning cartridges. AMASS automatically uses a cleaning cartridge from this group when it receives the appropriate SCSI request sense data from specific drives.
client
Program running on a workstation requests the services provided by a network server. Part of a client/server architecture.
