The modular design of an Oracle FS System provides a highly scalable storage facility. You achieve scalability by deploying a collection of specialized subsystems that are connected by external cables and internal cables to create a system.
External Ethernet cabling connects the Pilots to the customer’s management network.
Fibre channel (FC) and Ethernet iSCSI cabling connects the Controllers to the customer’s SAN-based data paths.
Power cables provide the AC power feed between the main power supply and the Oracle FS System.
Internal cabling of a system is completed during the manufacturing process.
Ethernet cabling between the Pilot nodes and the Controller nodes provides the private management interface (PMI) messaging.
Serial cross-connect cabling between the Pilot nodes provides a backup heartbeat path.
SAS cabling between the Controller nodes provides the paths for cache mirroring and redundant SAS data paths through the partner Controller to the Drive Enclosures.
SAS cabling from the Controller nodes to the Drive Enclosures supports the Backend SAS Interconnect.
SAS cabling among the Drive Enclosures extends the internal fabric to the Drive Enclosures.
Power cords from the hardware components to the power distribution units (PDUs) provide load balancing among the outlet groups.
For multiple rack systems, SAS cabling connects the hardware components across the multiple racks.
For system expansion, SAS cabling connects the added Drive Enclosures to the system.
