Cabling a mirrored HA pair

To cable a mirrored HA pair, you must identify the ports that you need to use on each node, cable those ports, and then cable the HA interconnect.

Before you begin

You must have cabled the SAS disk shelves. The disk shelf product library has instructions for cabling SAS disk shelves.

  1. Cabling the HA interconnect (all systems except 32xx or 80xx in separate chassis)
    To cable the HA interconnect between the HA pair nodes, you must make sure that your interconnect adapter is in the correct slot. You must also connect the adapters on each node with the optical cable.
  2. Cabling the HA interconnect (32xx systems in separate chassis)
    To enable the HA interconnect between 32xx controller modules that reside in separate chassis, you must cable the onboard 10-GbE ports on one controller module to the onboard 10-GbE ports on the partner.
  3. Cabling the HA interconnect (80xx systems in separate chassis)
    To enable the HA interconnect between 80xx controller modules that reside in separate chassis, you must cable the QSFP InfiniBand ports on one I/O expansion module to the QSFP InfiniBand ports on the partner's I/O expansion module.
