R RAID Redundant array of inexpensive or independent disks. A method of configuring multiple disk drives in a storage subsystem for high availability and high performance. S SAN See Storage Area Network. SAN agent A software program that communicates with the manager and controls the subagents. This component is largely platform independent. See also subagent. SCSI Small Computer System Interface. An ANSI standard for a logical interface to computer peripherals and for a computer peripheral interface. The interface utilizes a SCSI logical protocol over an I/O interface that configures attached targets and initiators in a multi-drop bus topology. Server A program running on a mainframe, workstation, or file server that provides shared services. This is also referred to as a host. Shared storage Storage within a storage facility that is configured such that multiple homogeneous or divergent hosts can concurrently access the storage. The storage has a uniform appearance to all hosts. The host programs that access the storage must have a common model for the information on a storage device. You must design the programs to handle the effects of concurrent access. Simple Network Management Protocol (SNMP) A protocol designed to give a user the capability to remotely manage a computer network by polling and setting terminal values and monitoring network events. SNMP See Simple Network Management Protocol. SNMP agent An implementation of a network management application that is resident on a managed system. Each node that is to be monitored or managed by an SNMP manager in a TCP/IP network must have an SNMP agent resident. The agent receives requests to either retrieve or modify management information by referencing MIB objects. MIB objects are referenced by the agent whenever a valid request from an SNMP manager is received. SNMP manager A managing system that executes a managing application or suite of applications. These applications depend on MIB objects for information that resides on the managed system. SNMP trap A message that is originated by an agent application to alert a managing application of the occurrence of an event. Software zoning This is implemented within the Simple Name Server (SNS) running inside the fabric switch. When using software zoning, the members of the zone can be defined with node WWN, port WWN, or physical port number. Usually the zoning software also allows you to create symbolic names for the zone members and for the zones themselves. SQL Structured Query Language. Storage administrator A person in the data processing center who is responsible for defining, implementing, and maintaining storage management policies. Storage area network (SAN) A managed, high-speed network that enables any-to-any interconnection of heterogeneous servers and storage systems. Glossary 755
