SAN data paths require FC and iSCSI connections. Single-mode and multi-mode optical fiber connections are supported on PCIe cards.
- Prerequisites:
The Fiber Channel (FC) data paths require 8 GbE or 16 GbE optical FC connections.
The iSCSI connections require 10 GbE copper or optical connections.
Note: The iSCSI SFPs are Gigabit Ethernet type, either 1 GbE or 10 GbE.
Note: The type of connection (Ethernet, FC, or iSCSI) was defined when the Oracle FS System was ordered.
CAUTION
Use only the Oracle-supplied SFP modules for the external cabling.The following figure shows the SAN HBA connections from the Controllers to the customer data network.

- For SAN FC connections, connect the FC cables from the SAN FC ports on the Controllers to the customer’s SAN environment.
- For SAN iSCSI connections, connect the 10 GbE optical or copper cables from the SAN ISCSI ports on the Controller to any open data ports available on two separate Ethernet network switches.
- Route the cables through the Controller cable management arm (CMA).Figure 2 Controller CMA
