System Overview
855-900547-200 1-8
1.2. Expandability
This section explains the expandability of this system and available configurations.
CAUTION
Contact the maintenance personnel of NEC to replace or
upgrade the system.
1.2.1. Adding
Processors
At least one processor is required in the main cabinet. Using the CPU expansion feature, the
Itanium2 processor can be added one by one. Up to four processors can be installed for each
cell. To install more than four processors, the cell must be added first using the cell expansion
feature. A maximum of 32 processors can be installed in the main cabinet.
1.2.2.
Expanding Memory Capacity
The minimum required memory capacity in the main cabinet is 2GB. This memory capacity can
be expanded up to 128GB for each cell. This means a maximum of 1TB of memory can be
installed in the main cabinet.
2GB, 4GB and 8GB memories are supported at present. For other memories, inquire the sales
personnel of NEC.
1.2.3. Adding
Cells
At least one cell is required in the main cabinet. For system expansion, such as the addition of
processors, the cell must be added first using the cell expansion feature. Up to 8 cells can be
installed in the main cabinet.
1.2.4.
Adding I/O Enclosures
At least one I/O enclosure is required in the main cabinet. A maximum of two enclosures can be
installed in the main and expansion cabinets, respectively.
1.2.5.
Adding I/O Modules
At least one I/O module is required in the main cabinet. It is contained in the I/O enclosure. A
maximum of four I/O modules can be installed in the main and expansion cabinets, respectively.
The device bay contained in the I/O module is able to accommodate up to four magnetic disk
units. 73GB, 146GB and 300GB HDD units are supported at present. For other HDD units,
inquire the sales personnel of NEC.
1.2.6.
Adding iSPs (Service Processors) (Duplicated Configuration)
An iSP (service processor) is installed in the main cabinet as standard equipment. A maximum
of two iSPs can be installed in the main cabinet.
