User group and user quotas can be tracked at the file system level or per
independent fileset.</span></p><p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt;font-family:Calibri">But
obviously as a customer I don't know if that "Really" depends

about 70% of our filesets in the Data Science Storage systems get backed
up to ISP. But that number may change over time as it depends on the requirements
of our projects. For them it is just selecting "Protect this DSS Container
by ISP" in a Web form an our portal then automatically does all the
provisioning of the ISP Node to one of our ISP servers, rolling out the
new dsm config files to the backup workers and so on.</span></p><br><span style=" font-size:12pt;font-family:Calibri"><br>Best Regards, </span><br><span style=" font-size:12pt;font-family:Calibri">Stephan Peinkofer</span><br><hr><br><span style=" font-size:11pt;font-family:Calibri"><b>From:</b> gpfsug-discuss-bounces@spectrumscale.org

the primary reasons for us are:</span></p><p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt;font-family:Calibri">-
Per fileset quota (this seems to work also for dependent filesets as far

Per user per fileset quota (this seems only to work for independent filesets)</span></p><p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt;font-family:Calibri">-
The dedicated inode space to speedup mmpolicy runs which only have to be
applied to a specific subpart of the file system</span></p><p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt;font-family:Calibri">-
Scaling mmbackup by backing up different filesets to different TSM Servers
