In this little demo I show you two improvements for storage stats processing.
One of them is small enhancement of IBM DS3000/DS5000 series statistics. Originally, DS-series do not provide average IO Size in their service dump, so I have taught Pytrend to recognize bandwidth (KB/sec or MB/sec) and IOPS data to correctly calculate average IO size.
Another small enhancement for graphs now shows Average and 95-percentile for each plotted value. It is required in most situation for determining correct workload profile. This feature is available for all storage types.
It is real pleasure doing such data processing with Python, so I am full of plans.
Note, that it took as little as 15 seconds to process service dump of each storage array. Most of this time is for saving plots, not for actual data processing.
If you would like to discuss how to analyse storage performance data, of course contact me at firstname.lastname@example.org
