In this environment setup, the production database runs across two physical R940-based nodes or servers. Each database server has four HBA ports or initiators that are connected to the XtremIO storage array by redundant FC switches.
On the XtremIO storage array, configure the storage that is based on the design for the physical production database environment.
Note: For detailed steps to create the Initiator Groups, volumes, and mappings that are based on the previously described design for the production database environment, see Appendix A.
- Create two Initiator Groups.
- Initiator Group 1 contains the four initiators from the first database cluster node.
- Initiator Group 2 contains the four initiators from the second database cluster node.
Record the four unique World Wide Names (WWNs) of the four HBA initiators in each of the physical database servers. You need these initiator WWNs when you create the two Initiator Groups on the XtremIO storage array.
- Create dedicated storage volumes for the clustered database, which includes separate volumes for OCR, DATA, REDO, FRA, and TEMP.[2]
The following table shows the XtremIO volume design for this two-node production database:

- Map the production database volumes to the two database servers by mapping the volumes that you created in step 2 to the two Initiator Groups that you created in step 1.
