System Overview

20 NAS 4000s and 9000s Administration Guide

■ Insight Manager is a comprehensive tool designed to be a key component in the systems

management environment. It monitors the operations of HP servers, workstations, and

clients. Insight Manager provides system administrators more control through

comprehensive fault and configuration management, and industry leading remote

management.

■ The Integrated Lights-Out feature provides remote access, sends alerts, and performs other

management functions, even if the operating system of the host server is not responding.

Product Redundancy

The NAS server is specifically designed to perform file serving tasks for networks. Using

industry standard components, redundancy of power supplies, NICs, and fans ensures

reliability.

The clustering ability of the NAS device further ensures continuous data availability, because

data being processed by one server transitions over to the other server in a failover situation.

Other industry standard features, such as redundant array of independent drives (RAID) and

remote manageability, further enhance the overall dependability of the NAS server.

The server contains dual 36.4 GB hard drives preconfigured with the NAS operating system so

that the active system volume is mirrored (RAID 1+0) to the second drive. If one of the

internal drives fails, the integrity of the system is preserved, because the system will use the

copy of the operating system on the remaining healthy drive. The drives in the server are

hot-pluggable, so the failed drive can be replaced while the system is running. When the failed

drive is replaced, the system automatically uses the version of the operating system on the

healthy drive to rebuild the replacement.

The NAS server includes dual power supplies. A power supply can be replaced while the

server is running. To ensure redundancy, it is important to connect each power supply to a

separate power source. If one power source fails, the server remains operational through the

second power source.

Through a seamless, hardware-based, graphical remote console, the Integrated Lights-Out port

provides the administrator with full control of the server from a remote location. Using a client

browser, the administrator can remotely power up, power down, and operate the console. A

built in processor makes the port independent of the server and the operating system.
