_____________________ Note _____________________
Dual power supplies are recommended for any BA356 shelf
containing a DS-DWZZH-05 UltraSCSI hub in order to
provide a higher level of availability between cluster member
systems and storage.
• The lower righthand device slot of the BA370 shelf within the RA7000
or ESA 10000 RAID array subsystems. This position minimizes cable
lengths and interference with disks.
A DS-DWZZH-05 UltraSCSI hub uses the storage shelf only to provide its
power and mechanical support (it is not connected to the shelf internal SCSI
bus).
______________________ Note _______________________
When the DS-DWZZH-05 is installed, its orientation is rotated
90 degrees counterclockwise from what is shown in Figure 3–3
and Figure 3–4.
The maximum configurations with combinations of DS-DWZZH-03 and
DS-DWZZH-05 UltraSCSI hubs, and disks in the same storage shelf
containing dual 180-watt power supplies, are shown in Table 3–3.
______________________ Note _______________________
With dual 180-watt power supplies installed, there are slots
available for six 3.5-inch SBBs or two 5.25-inch SBBs.
