Follow the steps in Table 10–1 to start the TruCluster Server hardwareinstallation procedure. You can save time by installing the Memory Channeladapters, redundant network adapters (if applicable), and KZPSA-BB orKZPBA-CB SCSI adapters all at the same time. Follow the directions in the referenced do...

The DWZZH-series UltraSCSI hubs are designed to allow more separationbetween member systems and shared storage. Using the UltraSCSI hub alsoimproves the reliability of the detection of cable faults. A side benefit is the ability to connect the member systems’ SCSI adapterdirectly to a hub port witho...
