The iSCSI configuration using SFP or optical connectors is used for smaller implementations, where the Oracle FS System has only iSCSI connectivity to the network and no FC SAN connectivity. The iSCSI configuration provides an iSCSI data path between the Oracle FS System and the Oracle MaxRep Replication Engine. The Replication Engine is connected to the customer’s LAN using 1 Gb/s or 10 Gb/s optical connections.
The iSCSI configuration using SFP or optical connectors requires three 10 Gb/s SFP HBAs to be installed in the PCIe slots of the Replication Engine in addition to the standard SAS RAID controller. The following figure indicates the HBAs that must be installed on the Replication Engine PCIe slots for the iSCSI configuration using SFP or optical connectors.
