Zoning
96-30052-001 Rev. A4 DataDirect Networks StorageScaler 8460 User Guide | 54
The SS8460 enclosure supports two zoning schemes. Zoning is configured by the storage
controllers.
B.1 Zoning Configuration 0
Zoning configuration 0 is the single zone configuration. In this configuration, all installed
disks are presented to all the host ports on both I/O modules (Figure 54).
B.2 Zoning Configuration 1
When zoning configuration 1 is active, the devices are divided into two groups of 42 disks as
shown in Figure 55.
Figure 56 illustrates how the disks are represented in zoning configuration 1. If host port 1
or host port 2 is connected, the devices in drive group 1 are reported. If host port 3 or host
port 4 is used, the devices in drive group 2 are reported. In this configuration, host port 5 is
not used and will be turned off.
