With Hitachi LUN Manager, open systems Logical Units LUNs can be defined, configured, and maintained. There is no more waiting for the hardware vendor to come and make configuration changes. Hitachi LUN Manager includes an easy-to-use, GUI-basedinterface that allows the easy definition of paths for LUNs, the reconfiguration of LUN-to-portassignments, or the viewing of the Lightning 9900 remote service information messages. Because the Hitachi LUN Manager can assign multiple paths to a single LUN, support of alternate path failover, path load balancing, and clustered systems is possible. Running on a standard Windows-basedPC connected to the storage subsystems by a dedicated LAN, Hitachi LUN Manager can support up to eight Lightning 9900 systems Hitachi CruiseControl Hitachi Data SystemsHitachi SANtinel Storage MaximizerHitachi Data Systems Professional Services Overview Professional Services and SupportData Protection Services Cost of Risk Analysis methodology CORARemote Copy Assessment and Implementation Service Data Protection Services LabHitachi NanoCopy Implementation Service Hitachi Data SystemsContinuous Availability Service Professional Services and SupportOn-lineData Migration Service SAN servicesHitachi Data Systems Software Portfolio Review and Analysis Servicethe Performance Experiment System Configurations forThe 7700E used all 6GB drives Hitachi Data Systems10BaseT Glossary of Terms100BaseT ACP pairAvailability Hitachi Data SystemsBack end Business Continuity Planning BCPCARB GlossaryCache CHIPConsistency Groups Hitachi Data SystemsControl Frame CORA Cost of Risk AnalysisGlossary Disaster RecoveryData Duplication Data MigrationEBCDIC Hitachi Data SystemsElectronic vaulting ESA/390Failover GlossaryFast Ethernet Fast writeHitachi Data Systems File BackupFICON Front EndGlossary Hitachi FlashAccessHDmS Hitachi CruiseControlHitachi Data Systems Hitachi Multiplatform Backup/RestoreHitachi InstantSplit Hitachi LUN ManagerGlossary Hitachi Rapid RecoveryHitachi Resource Manager Hitachi SANtinelHXRC Hitachi Extended Remote Copy Hitachi Data SystemsHYPERtape JavaGlossary Logical VolumeLightning 9900 Series Logical UnitMBCP Hitachi Data SystemsMIPS Meta-dataMTBF GlossaryMTTR NanoCopyOn-linesystem Hitachi Data SystemsOpen system Operating SystemGlossary Recovery TimeRAID RAID ControllersHitachi Data Systems SwitchSCSI SnapshotVolume Virtual Logical Volume Image ManagerGlossary SynchronousHitachi Data Systems Warm siteWorkload Corporate Headquarters Hitachi Data Systems Worldwide OfficesAsia Headquarters Australia/New Zealand Headquarters
