Black box testing was performed by running the same script in two configurations - one using a filer for VOB storage and the other using local disk. Start and end times were recorded in a log file and then compared to determine performance improvement. Conclusions Cleartext pool performance is improved by 2-3 times. Derived object pool performance is improved approximately 1.6 times. Source pool performance is improved approximately 1.1 times.
Single filer can service multiple VOBs with no degradation in performance.
Other Observations Size of the view cache has little impact on results. Linking the view storage area has little impact on results. Test Plan Running a set of ClearCase operations on a VOB server in two configurations, one using a filer and one without, black box testing was performed. Start and end times were recorded in a log file and then compared to determine performance improvement. Each storage pool has its own set of characteristics.
