Configuring AMP modes Not all ProLiant servers support all AMP modes. RBSU provides menu options only for the modes supported by the server. Advanced memory protection within RBSU enables the following advanced memory. • Advanced ECC Mode-Provides memory protection beyond Standard ECC. All single-bit failures and some multi-bit failures can be corrected without resulting in system downtime. • Online Spare Mode-Provides protection against failing or degraded DIMMs. Certain memory is set aside as spare, and automatic failover to spare memory occurs when the system detects a degraded DIMM. DIMMs that are likely to receive a fatal/uncorrectable memory error are removed from operation automatically, resulting in less system downtime. See the server-specific user guide for DIMM population requirements. • Mirrored Memory Mode-Provides protection against uncorrectable memory errors that would otherwise result in system failure. In this mode, the system maintains two copies of all data. If an uncorrectable memory error occurs, the system automatically retrieves the good data from the mirrored copy. The system continues to operate normally without any user intervention. If the system supports hot-plug memory, the failed memory can be replaced while the system continues to operate. • RAID Memory Mode-Provides protection levels similar to Mirrored Memory Mode, and it requires less memory allocation than full redundancy. Array Configuration Utility ACU is a browser-based utility with the following features: • Runs as a local application or remote service • Supports online array capacity expansion, logical drive extension, assignment of online spares, and RAID or stripe size migration • Suggests the optimum configuration for an unconfigured system • Provides different operating modes, enabling faster configuration or greater control over the configuration options • Remains available any time that the server is on • Displays on-screen tips for individual steps of a configuration procedure For optimum performance, the minimum display settings are 800 × 600 resolution and 256 colors. Servers running Microsoft® operating systems require Internet Explorer 5.5 (with Service Pack 1) or later. For Linux servers, refer to the README.TXT file for additional browser and support information. For more information, refer to the Configuring Arrays on HP Smart Array Controllers Reference Guide on the Documentation CD or the HP website (http://www.hp.com). Option ROM Configuration for Arrays The ORCA utility is supported when using an optional Smart Array controller mezzanine card or a directattach storage blade. Before installing an operating system, you can use the ORCA utility to create the first logical drive, assign RAID levels, and establish online spare configurations. The utility also provides support for the following functions: Software and configuration utilities 42
