The maximum length of the SCSI bus segment, including the combined length of BN38C cables and
internal device length, must not exceed 25 meters.

Figure 2–8 shows a three-member TruCluster configuration and an RA3000
pedestal with active/active or active/passive failover radially connected to a
DS-DWZZH-05 UltraSCSI hub. This configuration uses independent
connections to the two pedestal host ports to increase the available
bandwidth to the RA3000 controllers.
_______________________ Note _______________________
If you connect a DWZZH-05 host port to an RA3000 pedestal
host port to provide active/active failover, you must disable fair
arbitration on the DWZZH-05 by placing the fair arbitration
switch in the DISABLE position.
