This allows to detect if "low" LUNs are present which is critical to get optimal storage performance.</li> <li>the plot-sgpdd script should be reorganize (and simplified) to handle read, write, or both operations.</li> </ul> <p>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.</p> <p>I am going to provides patches for these items.</p> LU-3478
