CHAPTER 5
Oracle FS Systems: Cabling Overview
Cabling an Oracle FS System
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 cabling
External cabling involves the following types of cabling:
•
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
Internal cabling involves the following types of cabling:
•
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.
