NEC 1080Xd manual System Overview

Overview

Your Express5800/1080Xd server is a modular, multiprocessing server based on the Intel® Itanium® 2 64-bit processor. The combination of Intel Itanium 2 architecture, along with your server’s innovative crossbar switch and high-speed memory access technology, provides for massive power and scalability using the latest available operating systems. Your server is ideal for large-scale applications as well as compute intensive environments. Your server is conveniently housed in a rack-mount cabinet (see Figure 1-1).

Advanced features of your Express5800/1080Xd server include:

!High-speed processing and high scalability

High-speed processing is realized through a combination of the new Intel CPU and NEC crossbar switch and high-speed memory access technologies. In addition to support for up to 8 CPUs, the server employs the advanced PCI-X bus to connect peripheral and network devices and can be configured with up to 26 I/O slots, demonstrating the high scalability ideal for large-scale configurations.

!Partitioning functionality for flexible system operation

Your server can be partitioned at the hardware level, enabling each subsystem to operate as an independent computer system. It is possible to divide an 8 CPU system configuration into two subsystems, each of which has 4 CPUs, and let them each operate separately. In this way, it’s possible to allocate processor capacity according to workload status, resulting in flexible system operation and guaranteed security.

!High reliability and availability

Many hardware components allow redundancy, and the CPU/memory cell board and I/O card hardware are hot-swap compliant. Easy system recovery is possible even at the time of failure.
