Connecting Cluster Cables for Oracle ZFS Storage ZS7-2, ZS5-x, ZS4-4,
ZS3-x, and Sun ZFS Storage 7x20 Controllers
Oracle ZFS Storage ZS7-2, ZS5-x, ZS4-4, ZS3-x, and Sun ZFS Storage 7x20 controllers
employ serial-based clustering using two serial cluster links, and provide Ethernet
connectivity via one link. The Ethernet link provides a higher-performance transport for non-
heartbeat messages, such as rejoin synchronization, and provides a backup heartbeat.
The cables between the serial ports form a crossover pattern: 0 to 1 and 1 to 0. This
crossover cabling enables the use of straight-through cables between two identical
controllers.
For details about the cluster interface cards, see Controller Cluster I/O Ports.
Oracle ZFS Storage ZS7-2 Cluster Cabling
Three Category 5 Ethernet cables are provided: one green, one yellow, and one black. Each
cable is 2.5 meters in length.
• Connect either the green cable or the yellow cable from serial port 0 of one controller to
serial port 1 of the other controller.
• Connect either the green cable or the yellow cable from serial port 1 of one controller to
serial port 0 of the other controller.
• Connect the black cable between the Ethernet ports of each controller.
The following figure shows cluster cabling between two Oracle ZFS Storage ZS7-2
controllers (high-end model shown).
