•File Deletes. The number of bitfile delete requests processed in the Core Server since startup or
last reset of the statistics.
•Last Reset Time. The last time the subsystem statistics were reset. If this value is 0, the statistics
have not been reset since server startup.
Name Space Statistics:
•Files. The number of files managed by this Core Server.
•Directories. The number of directories managed by this Core Server.
•Symbolic Links. The number of symbolic links managed by this Core Server.
•Hard Links. The number of hard links managed by this Core Server.
•Junctions. The number of junctions managed by this Core Server.
•Filesets. The number of filesets managed by this Core Server.
•Total Name Space Objects. The total number of namespace records in the database. Note that this
total may not match the total achieved by summing the number of the above objects. Some objects,
such as hard links, require more than one record.
Disk/Tape Statistics:
•Total Disk Virtual Volumes. The number of Disk Virtual Volumes managed by this Core Server.
•Total Tape Virtual Volumes. The number of Tape Virtual Volumes managed by this Core Server.
•Tape Aggregates. The number of tape aggregates managed by this Core Server. A tape aggregate
is a single tape storage segment that contains more than one file.
•Files in Tape Aggregates. The number of files in the tape aggregates managed by this Core
Server.
•Bytes in Tape Aggregates. The number of bytes stored in the tape aggregates managed by this
Core Server.
•Active Disk Bytes. This is the sum of the bytes in the storage segments assigned to files, including
slack space. Slack space is the disk space assigned to disk storage segments that is not occupied
with file data. The sum of the lengths of files on disk will be less than the Active Disk Bytes
because of the presence of slack space.
•Free Disk Bytes. This is the sum of the bytes not assigned to files. More preci sely, it is the sum of
the disk volume bytes not assigned to disk storage segments.
•Active Tape Bytes. This is the sum of the bytes assigned to files on tapes. It does not include
deleted file space that has not been reclaimed.
