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 Cost of Risk Analysis methodology CORA Professional Services and SupportProfessional Services Overview Data Protection ServicesHitachi Data Systems Data Protection Services LabRemote Copy Assessment and Implementation Service Hitachi NanoCopy Implementation ServiceSAN services Professional Services and SupportContinuous Availability Service On-lineData Migration ServiceHitachi Data Systems Software Portfolio Review and Analysis Servicethe Performance Experiment System Configurations forThe 7700E used all 6GB drives Hitachi Data SystemsACP pair Glossary of Terms10BaseT 100BaseTBusiness Continuity Planning BCP Hitachi Data SystemsAvailability Back endCHIP GlossaryCARB CacheCORA Cost of Risk Analysis Hitachi Data SystemsConsistency Groups Control FrameData Migration Disaster RecoveryGlossary Data DuplicationESA/390 Hitachi Data SystemsEBCDIC Electronic vaultingFast write GlossaryFailover Fast EthernetFront End File BackupHitachi Data Systems FICONHitachi CruiseControl Hitachi FlashAccessGlossary HDmSHitachi LUN Manager Hitachi Multiplatform Backup/RestoreHitachi Data Systems Hitachi InstantSplitHitachi SANtinel Hitachi Rapid RecoveryGlossary Hitachi Resource ManagerJava Hitachi Data SystemsHXRC Hitachi Extended Remote Copy HYPERtapeLogical Unit Logical VolumeGlossary Lightning 9900 SeriesMeta-data Hitachi Data SystemsMBCP MIPSNanoCopy GlossaryMTBF MTTROperating System Hitachi Data SystemsOn-linesystem Open systemRAID Controllers Recovery TimeGlossary RAIDSnapshot SwitchHitachi Data Systems SCSISynchronous Virtual Logical Volume Image ManagerVolume GlossaryWarm site Hitachi Data SystemsWorkload Australia/New Zealand Headquarters Hitachi Data Systems Worldwide OfficesCorporate Headquarters Asia Headquarters
