    1 Introduction Overview This manual describes how to install, set up, and use the FCArray Assistant Client/Server software on HP NetServers using Microsoft’s Windows NT 4.0 Workstation and Server operating systems. The FCArray Assistant software is delivered on the CD-ROM accompanying the hardware. However, diskettes must be created to install the software.

  • Page 8: Monitoring Functions, Configuration Functions

    FCArray Assistant Server is sufficient for these tasks. The FCArray Assistant Client software, an additional component available from Hewlett-Packard, accesses this information and then organizes it through an intuitive graphical display. Errors and events are recorded in a log and if a problem is serious enough to warrant immediate attention, operators can be alerted electronically via popup windows, pagers, fax or e-mail, if desired.

  • Page 9: Management Functions, Maintenance Functions, Client/server Requirements

    Chapter 1 Introduction The RAID Assistant is an intuitive, wizard-like utility that can automatically configure the disk arrays. In Automatic Configuration mode, the utility operates interactively with the user to answer a few simple questions and then automatically configures the disk arrays. The Assisted Configuration and the Manual Configuration modes provide more control over drive group setup or individual configuration parameters.

For a Dual Active controller configuration, the load should be balanced across the two controllers. In the event of a failure to either controller, the surviving controller will activate its failover port and transparently take over the workload of the failed controller.

This state is sometimes referred to as "Write-Only" (WRO). RAID RAID stands for Redundant Array of Independent Disks.

    Appendix B Glossary Level 5 Data is "striped" across several physical drives. For data redundancy, drives are encoded with rotated XOR redundancy. Level 0+1 Combines RAID 0 striping and RAID 1 mirroring. This level provides redundancy through mirroring. Levels 00, 10, 30, and 50 Multi-layer RAID levels, which span RAID levels 0, 1, 3, and 5 by striping data across, drive groups (RAID Drives).

    Appendix B Glossary A "standby" disk drive of identical or larger size is found attached to the same controller. All of the system drives that are dependent on the failed disk are redundant system drives, for example, RAID 1, RAID 3, RAID 5, and RAID 0+1.
