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).

Oracle ZFS Storage ZS5-x Cluster Cabling

Three Category 5 Ethernet cables are provided. Each cable is 2.5 meters in length.

  • Connect one cable from serial port 0 of one controller to serial port 1 of the other controller.

  • Connect the second cable from serial port 1 of one controller to serial port 0 of the other controller.

  • Connect the third cable between the Ethernet ports of each controller.
