I am trying to optimise the performance of an MSA 2040 DAS which provide storage to a 2 nodes cluster. The hosts are using qlogic 8GB HBA (82Q) and am trying to set the Queue depth. Using the SANsufer I can see the execution throttling value of 65553 ! such a big value. I need to set the queue depth to between 48 - 64. My question is what value of qlogic execution throttling will equal to queue depth value of 64 for example ? or simply put , what ieases the mapping between the queue depth and execution throttling?
Please advise. thanks.
