HP NetServer LH3000 with HP Rack Storage/12FC & HP Rack Storage/12 Cluster Configuration Guide 5 September 2000 (see Versions at the end of this document) Introduction This document defines the supported HP NetServer LH3000 configurations using the HP Rack Storage/12FC and Microsoft Cluster Server and one or two HP Rack Storage/12s. These configurations minimize single points of failure (SPOF) and provide extended availability. The specific configuration certified and supported by both Hewlett-Packard and Microsoft is defined, as are other guidelines to assist you in configuring your clustered NetServers. This guide is prescriptive; it describes the configurations supported by HP. Any deviance to these configurations can result in an inoperative cluster or an operating cluster with degraded performance, hidden SPOFs, etc., and therefore will not be supported by HP. What's Defined in a Cluster • Cluster • SPUs • Local and Shared Storage • Intra-cluster and Client LANs • Shared Storage Cabling Cluster Type of SPUs Installation Number of nodes Shared Storage LANs: Client LAN Intra-cluster (Heartbeat) LAN Power source System software: HP NetServer LH3000 Each node must be the same model SPU, but may have different clock speeds, main memory sizes, cache sizes, and number of CPUs. Pedestal or racked 2 HP Rack Storage/12FC with two FCArray Cards, HP disks, and using a HP D8602A HBA in each server. See Shared Storage below. Any NIC that is HP and Microsoft approved. See Client LAN below. Embedded NIC with crossover cable. See Intra-cluster LAN below. Direct from power mains, power conditioner or uninterruptible power supply (UPS) using any power conditioner or UPS. Redundant power distribution units (PDU's) are strongly recommended. 1
