Hi all,

 

I am looking for the best queue depth and other HBA configuration settings to maximize Oracle 12c RAC and ASM performance with Hitachi HBA configuration. Based on your experience testing performance for Oracle, what values have worked best for you with queue depth settings? The default HBA queue depth setting for Hitachi HBA is 32 but I wanted to find out what your experiences have been setting it to a much higher value with Oracle 12c performance in terms of large and small read and write I/O performance for OLTP, DSS and mixed workloads.

 

Thanks,

Ben
