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 Data Systems Hitachi CruiseControl Storage Maximizer Hitachi SANtinel Hitachi Data Systems Professional Services and Support Professional Services OverviewData Protection Services Cost of Risk Analysis methodology CORA Data Protection Services Lab Remote Copy Assessment and Implementation ServiceHitachi NanoCopy Implementation Service Hitachi Data Systems Professional Services and Support Continuous Availability ServiceOn-lineData Migration Service SAN services Software Portfolio Review and Analysis Service Hitachi Data Systems System Configurations for the Performance Experiment Hitachi Data Systems The 7700E used all 6GB drives Glossary of Terms 10BaseT100BaseT ACP pair Hitachi Data Systems AvailabilityBack end Business Continuity Planning BCP Glossary CARBCache CHIP Hitachi Data Systems Consistency GroupsControl Frame CORA Cost of Risk Analysis Disaster Recovery GlossaryData Duplication Data Migration Hitachi Data Systems EBCDICElectronic vaulting ESA/390 Glossary FailoverFast Ethernet Fast write File Backup Hitachi Data SystemsFICON Front End Hitachi FlashAccess GlossaryHDmS Hitachi CruiseControl Hitachi Multiplatform Backup/Restore Hitachi Data SystemsHitachi InstantSplit Hitachi LUN Manager Hitachi Rapid Recovery GlossaryHitachi Resource Manager Hitachi SANtinel Hitachi Data Systems HXRC Hitachi Extended Remote CopyHYPERtape Java Logical Volume GlossaryLightning 9900 Series Logical Unit Hitachi Data Systems MBCPMIPS Meta-data Glossary MTBFMTTR NanoCopy Hitachi Data Systems On-linesystemOpen system Operating System Recovery Time GlossaryRAID RAID Controllers Switch Hitachi Data SystemsSCSI Snapshot Virtual Logical Volume Image Manager VolumeGlossary Synchronous Warm site Hitachi Data SystemsWorkload Hitachi Data Systems Worldwide Offices Corporate HeadquartersAsia Headquarters Australia/New Zealand Headquarters
