2 Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide Fibre Channel Fibre Channel Arbitrated Loop (FC-AL) Fibre Channel Fabric GBIC-SW module Heartbeat High availability Hot-pluggable Hot spare Interconnect Integrated Distributed Lock Manager IP Address LAN An IEEE standard for providing high-speed data transfer among workstations, mainframes, supercomputers, desktop computers, storage devices, and display devices. A data path from the Fibre Host Adapters in the cluster nodes to the array controllers in the RA4000 Arrays or RA4100 Arrays. A PDC/O2000 requires one or more redundant FC-ALs. Each FC-AL is redundant because there are at least two paths from each node to each RA4000/RA4100 Array. A storage area network (SAN) topology that uses Fibre Channel SAN Switches to connect cluster nodes with shared storage resources. Gigabit Interface Converter-Shortwave module. A module installed at both ends of a Fibre Channel cable. A signal transmitted between cluster nodes to indicate whether the nodes are operating. A term used to identify a computer system that can continuously deliver services to its clients 99.9 percent of the time (no more than 8.5 hours of downtime per year). A computer component that can be removed and replaced without powering down the system. A computer component that is powered on, not actively processing data, and awaiting a request to take over operation of a failed component. A physical connection between cluster nodes that transmits intra-cluster communication, also called the cluster heartbeat. The Compaq Parallel Database Cluster interconnect is dedicated to servicing requests only between cluster nodes. An Oracle software component that coordinates database locks among cluster nodes. Sometimes abbreviated as IDLM. Internet Protocol Address. An address assigned to a network interface card, which computer entities use to locate and communicate with each other. IP addresses can be statically or dynamically assigned. Local Area Network.
