Table 9–3 shows the components used to create the cluster shown in
Figure 9–12 and Figure 9–13.
Figure 9–13 shows two AlphaServer systems in a TruCluster Server
configuration with dual-redundant HSZ50 RAID controllers at the end of
the shared SCSI bus. As with Figure 9–12, the SCSI bus adapters are
KZPSA-BB PCI-to-SCSI adapters. They could be KZPBA-CB host bus
adapters without changing any cables.
