NEC HX4500 manual System Overview

Overview

The server is a modular, multiprocessing server based on the Intel® Pentium®

IIXeon chip set. The chip set incorporates a modular scaleable architecture that integrates a 64-bit bus interface with three Peripheral Component Interconnect (PCI) buses and an Industry Standard Architecture (ISA) bus. The architecture supports Symmetrical Multiprocessing (SMP) and a variety of operating systems. The chassis and system boards are designed to meet the needs of the server marketplace.

The combination of computing performance, memory capacity, and integrated I/O provides a high performance environment for many applications including network servers and multi-user systems. The server is designed for use in applications where downtime must be minimized. To this end, the server includes or has the option to include the following.

Power system redundancy; in a system configured with redundant power supplies, the system will continue to operate with a single power supply failure.

Self-contained power supply units that can be easily installed or removed from the back of the chassis.

Hot-swap SCSI hard drive bays accessible from the front of the chassis; a failed drive can be removed, and a new drive installed without system power being turned off.

High degree of SCSI hard disk fault tolerance and advanced disk array management features through the use of RAID (Redundant Array of Independent Disks) technology.

Hardware monitors (temperature and voltage) and software monitors to

Tindicate failures.

Easy access to all parts for service.
