You can configure the bandwidth that is used for moving
stub files. You can also configure how many stub files are identified
before a move process begins.
Use the HSM for Windows client GUI Preferences window Move
Settings tab to configure two move settings:
- Bandwidth
- The Bandwidth value controls what percent
of time the HSM for Windows client spends
on move operations. For example, if you set Bandwidth=40% and
a move operation takes 20 milliseconds, the HSM for Windows client pauses for 30
milliseconds before the next move operation starts. The total elapsed
time is 50 milliseconds, the move operation is 20 milliseconds (40%)
of the elapsed time.
- Stub Files
- The Stub Files value controls how many
stub files are identified before a move operation begins. The HSM for Windows client moves the stub
files in an optimal order to minimize the number of tape mounts and
seeks. When the list of stub files is large, more files can be moved
with fewer tape mounts. However, it takes more time for the HSM for Windows client to identify a
large number of stub files. A larger value improves the efficiency
of the move process, but delays the start of the move operation.
The value can be 1 to 50,000. The
default is 5,000.
