4: System Configurations
Storage
Each Origin 300 base module contains two disk-drive bays; however, you can add
additional storage to the system. The TP900 storage module provides a SCSI JBOD
solution for the Origin 300 system with NUMAlink module. The TP900 can be configured
as follows:
•
For a single-port configuration (eight drives), one I/O module is required (bay 1/1).
•
For a dual-port configuration (four drives per port), use two I/O modules.
•
Populate all disk drive bays with a
disk drive or a filler plate.
•
Install the drives in the following order:
The TP900 storage module resides in the Origin 300 rack. The placement of the storage
modules within the rack depends on the number of other modules in the rack. The
following rules apply:
•
In the short rack, place the TP900 in the highest available location of the rack. For
example, if the short-rack system contains two base modules, one NUMAlink
module, and one PCI expansion module, place the TP900 storage module in U16. If
you want to add another storage module to the system, place it in U14.
•
In the tall rack, the placement of the TP900 storage module alternates between the
top and bottom portions of the rack; the storage modules do not have to be grouped
together.
In the bottom portion of the rack, place the first TP900 module in location U10. If
this location is not available, place the TP900 in the next available location in the
bottom portion of the rack (for example, U8).
Place the second TP900 in location U30. If this location is not available, place the
TP900 in the next available location in the top portion of the rack (for example, U32).
Continue to alternate between the top and bottom portions of the rack as you place
the TP900 modules in the system.
Note:
Locations U12 through U29 are reserved for the NUMAlink, Origin 300 base,
and PCI expansion modules. If you need additional rack space for storage modules
and space is available within U12 through U29, you may place additional TP900
modules within this reserved space.
The Origin 300 base modules can connect to the TP900 storage module via the SCSI port
connector on the rear of the Origin 300 base module or via a low-voltage differential
(LVD) PCI card (refer to Figure 4-5).
