NX7700i/5020M-16 System Overview

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 for the base module. 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 8 processors can be installed in the base module.

1.2.2.Expanding Memory Capacity

The minimum required memory capacity for the base module is 2GB. This memory capacity can be expanded up to 64GB for each cell. This means a maximum of 128GB of memory can be installed in the base module.

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 for the base module. For system expansion, such as the addition of processors, the cell must be added first using the cell expansion feature. Up to 2 cells can be installed in the base module.

1.2.4.Adding I/O Modules

At least one I/O module is required for the base module. A maximum of two I/O modules can be installed in the base module.

A maximum of four magnetic disk units can be mounted on the built-in device bay of the I/O module. The magnetic disk units supported at present are 73GB, 146GB and 300GB HDD. For other types, contact the sales personnel of NEC.

1.2.5.Adding Peripheral Units

The iSP is installed in the base module to satisfy various customer’s requirements for system configurations. The system is designed to connect a wide variety of peripheral units through this iSP. Peripheral units can also be connected through various types of PCI cards available on the I/O module.
