About adding 3U16 storage shelves to an
operational appliance
Configurations
The NetBackup 5230 Appliance supports up to four storage shelves.
The following scenarios define the supported and unsupported configurations.
■
You can add up to four 3U16 shelves to a standalone NetBackup 5230 Appliance
that has no storage shelves attached.
■
You can add 2U12 storage shelves to an NetBackup 5230 Appliance that already
has at least one 3U16 shelf for a total of four shelves. In doing so, you must
connect the 2U12 storage shelf to the last daisy-chained 3U16 storage shelf
that is connected to the appliance.
For example, NetBackup 5230 App 3U16 24TB Storage Shelf + 3U16
24TB Storage Shelf + 3U16 36TB Storage Shelf +
2U12 49TB Storage Shelf
.
In addition, attaching a 2U12 storage shelf to a 3U16 storage shelf requires a
SAS3-to-SAS2 cable to connect the shelves. Finally, the SAS3 data transfer
rate of the 2U12 storage shelf drops to match the SAS2 data transfer rate of
the 3U16 storage shelf.
■
You cannot add additional storage shelves to an NetBackup 5230 Appliance
that already has four connected shelves.
Note:
Veritas does not support adding additional storage shelves to an existing
system without first shutting down the NetBackup 5230 Appliance and all attached
storage shelves.
See
on page 50.
Hardware requirements
A NetBackup 5230 Appliance that does not have storage shelves needs additional
components to support the new storage shelves. The components in the NetBackup
Expansion Storage Kit must be installed into the appliance. The appliance must be
turned off during the installation.
Caution:
Veritas service technicians must perform all tasks that involve the inside
of the appliance chassis.
Note:
When you add an additional storage shelf to an operational appliance, Veritas
recommends that you schedule this task during low system activity.
