Compaq servers and storage deliver on this reputation by offering the highest level of reliability and uptime with features such as: • Industry standard PCI Hot Plug and internal hot-plug storage • Redundant hot-plug fans, power supplies, and NICs • Automatic Server Recovery-2 (ASR-2) • ECC protected memory • Integrated Management Display (IMD) • Integrated Remote Console (IRC) • Compaq SmartStart and Compaq Insight Manager The Compaq ProLiant Cluster for NetWare 4.2 is designed to help customers reduce the risk and costs of downtime due to hardware or software failures. Benefits include: • Automatic failover protection - In the event of a failure on one server, the remaining server maintains availability of network data and resources. • Active servers - Users can now cluster two active NetWare 4.11 or NetWare 4.2 servers on the network, providing failover support and significant cost savings, since purchasing a dedicated server for failover is no longer necessary. • Shared storage - Support for shared storage devices allows customers to reduce overall management costs by centralizing administration and back-up. Shared storage also allows more efficient use of storage space by eliminating the need to maintain duplicate files on different servers. • No single point of failure - The new Compaq StorageWorks RAID Array 4000 storage system provides redundant fibre channel loops for No Single Point of Failure configurations. The ProLiant Cluster for NetWare 4.2 provides the highest levels of system and application availability for customers with high system uptime requirements for NetWare 4.x environments. These levels are necessary to meet the requirements of demanding business-critical environments. This Integration Note details the configuration options and server requirements, provides insight into the administration, and describes some of the features available with the ProLiant Cluster for NetWare 4.2.
