Understanding and Maintaining Components
RAID Controllers (6320SS and 7320SS only)
The 6320SS and 7320SS storage subsystems house one or two RAID
controllers. The subsystems provide configurations for single
stand-alone and dual active-active/active-passive controller
solutions.
In the stand-alone mode, the controller operates autonomously. In
the active-active/active-passive mode, the two controllers operate
as a pair. If one controller fails in the active-active/active-passive
mode, the other can take over the failed controller’s work.
The Adaptec Disk Array Administrator storage management tool
is embedded in the controller firmware. See
and the
Adaptec Disk Array
Administrator User’s Guide
on your
DuraStor CD
for more
information.
Figure 5-2 RAID Controller and Canister
The DuraStor 6320SS includes a single Ultra160-to-Ultra160 SCSI
RAID controller as standard equipment. The controller has two
Ultra160 host channels that connect to four host I/O ports on the
subsystem and two Ultra160 SCSI disk channels connecting to two
disk I/O ports. This controller is referred to in this
Guide
and in the
storage management software as the DuraStor 6200S.
The DuraStor 7320SS includes a Fibre Channel-to-Ultra160 SCSI RAID
controller a standard equipment. The controller has four 2 Gigabit FC
host ports and four Ultra160 SCSI disk channels. This controller is
referred to in this Guide and in the storage management software as
the DuraStor 7200S.
