High Availability RequirementsThis section summarizes the requirements for high availability. Through ACPI and OnNow power management capabilities, Windows 2000 allows more control of dynamic configuration changes and power state changes. These features help implementers in handling event-based issues such as lights that are keyed to system failures, pending failures, or system power states. 223. System includes alert indicators for occurrence of failure
Alert indicators should be provided that indicate hard failure. In addition to visual alerting mechanisms, a design can also provide software alerts such as paging, fax, or e-mail notifications. The following are required sources of alert indicators for hard failures for systems running Windows 2000 Advanced Server and Datacenter Server. These indicators are recommended for servers running other server versions of Windows 2000.
Recommendation Recommended: These sources of alert indicators for hard failures are recommended for all servers:
224. Hot-swappable drive includes a local disk drive replacement indicatorRequired A hot-swappable drive must have a local indicator that shows which drive or drives are ready for replacement, facilitating the servicing process and improving reliability by reducing possible errors. This indicator should be on the drive chassis, not on the screen. The Device Bay “eject” signal can be used to activate a replacement indicator. Designers can choose to use existing LEDs for dual purposes to fulfill this requirement, but the LED display should clearly show when a drive is ready for removal, as opposed to other information the display would normally provide. For systems with multiple drives, an individual replacement indicator should be physically associated with each hot-swappable drive slot. 225. System includes alert indicators for imminence of failure
Alert indicators that indicate informative failure are required for servers running Advanced Server or Datacenter Server and should be provided for all servers. The hard failure and informative failure indicators cannot be on simultaneously. In addition to visual alerting mechanisms, a design can also provide software alerts such as paging, fax, or e-mail notifications. The following are required sources of alert indicators for imminent failures for systems running Windows 2000 Advanced Server and Datacenter Server. These are recommended for servers running other server versions of Windows 2000:
226. IA-64 system supports monitoring for power and down conditionsRequired The following monitoring capabilities are required for the hardware, SAL and firmware on IA-64 systems.
