We used a four-node Dell EMC software-defined, all-flash, SAS-SSDs-based enterprise array as the shared Oracle Database storage. Each storage node had two dedicated 25 GbE ports for data traffic. On the shared storage array, we created eight volumes for Oracle DATA (includes HLR benchmarking schema and TimesTen cache management objects), four volumes for Oracle REDO logs, three volumes for Oracle OCR-Voting Disks, and six volumes for Oracle TEMP, and presented them to the two RAC nodes.
