We used DD9300 as the backup appliance to test the backup and recovery of an Oracle database in this reference architecture. Four front-end 10 GbE interfaces spread across two NICs installed in the DD9300 were connected to the same spine switches that the MX network switches were connected to. This provided highly available connectivity and sufficient bandwidth between the MX840c database servers and the DD9300 backup appliance. The interfaces configured for public network traffic within the database servers were used for the backup and recovery traffic as well. For this communication to happen, the 10 GbE interfaces on the DD9300 were also configured within this same public IP network address range.
For details about the DD9300 and the database server configuration, backup and recovery test methodology and results, see Chapter 5 Data Domain Backup and Recovery Solution.
