NEC 1080Xd manual Main Components, Itanium 2 Processors, System Memory, PCI-X Core Module

Main Components

The following sections provide information about the components in the main chassis.

Itanium 2 Processors

Depending on system configuration, your system includes four or eight Intel Itanium 2 64-bit 1.3-GHz/3-MB or 1.5-GHz/6.0-MB processors. Four Intel Itanium 2 processors are installed within one CELLV board. See Figure 1-5. A second CELLV board has an additional four Intel Itanium 2 processors. All processors installed in your system must be of identical bus and core speed.

System Memory

Each CELLV board in your system contains sixteen 168-pin DIMM sockets.

See Figure 1-5. Memory DIMMs must be populated four at a time with 1-GB ECC SDRAM DIMMs. Depending on the number of DIMMs installed, your system may include from 4 GB up to a maximum of 32 GB of memory using 1-GB DIMMs.

PCI-X Core Module

The server’s expansion capabilities meet the needs of file and application servers for high performance I/O by providing twelve hot-swap PCI-X expansion slots within the Core Module. The Core Module consists of a CrossBar Controller (XBC) and an I/O Router (IOR). The Core Module can be connected with up to two CELLV Boards, to control data transfers between the CELLV Boards.

The Core Module includes five full-length and three half-length 64-bit/66-MHz hot- swap PCI-X slots and three full-length and one half-length 64-bit/133-MHz hot-swap PCI-X slots. The PCI-X slots allow PCI-X boards to be installed or removed while the server is powered on (if the operating system supports the Hot Plug PCI function). A Basic I/O Board to support standard I/O interface and a video VGA controller board are installed in the Core Module. The Basic I/O Board and video VGA board are not hot- swappable.

Note: Your operating system must support the Hot Plug PCI function.

A DVD-ROM drive is installed in the Core Module as standard equipment. Optionally, a DAT tape drive or USB FDD and up to 4 disk storage hard disk drives may be added to the Core Module. See Figure 1-2.
