Description
This is the continuation of work done in LU-2043.
Similarly to obdfilter-survey scripts,
- the output of sgpdd-survey should be fixed to display minimal and maximal bandwidth of sgp_dd instances. This allows to detect if "low" LUNs are present which is critical to get optimal storage performance.
- the plot-sgpdd script should be reorganize (and simplified) to handle read, write, or both operations.
Additionally, the sgpdd-survey script could be enhanced to support NUMA servers. Each sgp_dd instance would need to be binded to the cores local to the device it works on.
I am going to provides patches for these items.
