A customer has recently deployed an XtremIO 20 TB two X-Brick cluster to run an existing instance of Oracle RAC previously leveraging VNX for back-end storage. The application environment uses a block size of 1 MB. Multiple tables are in use with the PARALLEL_DEGREE_POLICY variable set to AUTO. The customer wants your help with tuning the DB_FILE_MULTIBLOCK_READ_COUNT parameter for best performance with XtremIO. Which values should be recommended for tuning the DB_FILE_MULTIBLOCK_READ_COUNT parameter in the Oracle RAC environment?

XtremIO storage is optimized for high performance with large block sizes. Setting DB_FILE_MULTIBLOCK_READ_COUNT to 64 or 128 aligns with the 1 MB block size used by the application, allowing efficient read operations and maximizing throughput.
