System Overview ■ 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. 20 NAS 4000s and 9000s Administration Guide
