LaCie 12big Rack Fibre 8 User Manual System Overview page 18 1.4.2.3. StoreView Management Software The StorView Storage Management software is embedded on the RAID Controller module and is a full-featured graphical HTMLbased software suite designed to configure, manage and monitor the 12big Rack Fibre 8 and 12big Rack Fibre Expansion storage solutions. The module is supplied configured with a base IP address to allow the user to connect and access the controller's embedded StorView software. Please refer to 3.4. Starting StorView for further information and the StorView Storage Management Software RAID Module User Guide. 1.4.3. Disk I/O Module The 12big Rack Fibre Expansion enclosure houses one or two Disk I/O Modules. They provide drive expansion for the RAID enclosure. When expanding the storage system, you may add up to seven Expansion enclosures. This will give you a total of eight enclosures including the RAID enclosure for a maximum of 96 SAS or SATA disk drives. IMPORTANT INFO: Do not mix Disk I/O Modules and RAID Controllers in the same enclosure. Processors on the Disk I/O Modules provide enclosure management and an interface to the devices on the backplane, Power Cooling Modules and OPS panel, which monitors the internal functions. In a dual module configuration, these processors operate in a masterslave configuration to allow for path failover in the event of a single module failure. If only one Disk I/O Module is installed, a Blank I/O module must be installed in the unused I/O Bay #1 (lower). The single Disk I/O Module is installed in the I/O Bay #0 (upper). Each Disk I/O Module has three SAS connectors and each connector has four adjacent LEDs. The LEDs indicate status or I/O activity on that specific lane of the SAS port. The module also has a Fault and ID LEDs. Refer to Table 04 for details on these LEDs. In a multiple enclosure configuration, the "OUT" port on the RAID Controller or Disk I/O Module connects to the "IN" port on the Disk I/O Module in the next Expansion enclosure (12big Rack Fibre Expansion). Please refer to section 2.6. Cabling Multiple Enclosures for more information on cabling Expansion enclosures. continued on the next page>> Fig. 12 - Disk I/O Module Fig. 13 - Disk I/O Module Front Panel TECHNICAL NOTE: The white diamond icon with arrow pointing away from the connector indicates a SAS OUT port, and a white circle icon with an arrow pointing towards the connector indicates a SAS host IN port.

1.4.2.3. StoreView Management Software
The StorView Storage Management software is embedded on the
RAID Controller module and is a full-featured graphical HTML-
based software suite designed to configure, manage and monitor
the 12big Rack Fibre 8 and 12big Rack Fibre Expansion storage
solutions. The module is supplied configured with a base IP address
to allow the user to connect and access the controller’s embedded
StorView software. Please refer to
3.4. Starting StorView
for further
information and the StorView Storage Management Software RAID
Module User Guide.
1.4.3.
Disk I/O Module
The 12big Rack Fibre Expansion
enclosure houses one or two Disk
I/O Modules. They provide drive expansion for the RAID enclosure.
When expanding the storage system, you may add up to seven Ex-
pansion enclosures. This will give you a total of eight enclosures
including the RAID enclosure for a maximum of 96 SAS or SATA
disk drives.
IMPORTANT INFO:
Do not mix Disk I/O Modules and RAID
Controllers in the same enclosure.
Processors on the Disk I/O Modules provide enclosure management
and an interface to the devices on the backplane, Power Cooling
Modules and OPS panel, which monitors the internal functions. In
a dual module configuration, these processors operate in a master-
slave configuration to allow for path failover in the event of a single
module failure.
If only one Disk I/O Module is installed, a Blank I/O module must
be installed in the unused
I/O Bay #1 (lower). The single Disk I/O
Module is installed in the I/O Bay #0 (upper).
Each Disk I/O Module has three SAS connectors and each connec-
tor has four adjacent LEDs. The LEDs indicate status or I/O activity
on that specific lane of the SAS port. The module also has a Fault
and ID LEDs. Refer to
Table 04
for details on these LEDs.
In a multiple enclosure configuration, the “OUT” port on the RAID
Controller or Disk I/O Module connects to the “IN” port on the
Disk I/O Module in the next Expansion enclosure (12big Rack Fibre
Expansion). Please refer to section
2.6. Cabling Multiple Enclosures
for more information on cabling Expansion enclosures.
