run concurrently. Reliability is enhanced with retry logic, alternate path routing, and restart from point of failure. Ease of use is provided by a Java-client interface, a system monitor, scheduling support, and remote control of client functions from OS/390®.

HDD

High-density disks. Used in the Lightning 9900™ Series.

HDmS

The Hitachi Data Systems Migration Service™ (HDmS) is a Hitachi Data Systems® professional service that helps users migrate data from existing systems to newly installed systems while minimizing the impact on mission-critical applications. HDmS features a four-phase approach that includes assessment, planning, migration, and post-migration support.

Hitachi CruiseControl™

CruiseControl™ automatically monitors, analyzes and moves logical volumes to eliminate “hot spots” within a Lightning 9900 storage system and provides load balancing to maintain predetermined performance levels.

Hitachi Dynamic Link Manager™

Hitachi Dynamic Link Manager™ is a family of software utilities that is server based and enhances RAID systems by providing automatic failover and load balancing from server-to-RAID channel connection failures. This product allows systems administrators to take advantage of the multiple paths on a Lightning 9900™ by adding redundant SCSI connections between data servers and RAID systems. Hitachi Dynamic Link Manager™ therefore provides increased reliability and performance. Supported platforms include AIX®, Sun Solaris™, and Windows NT/2000®.

Hitachi FlashAccess™

FlashAccess™ is a Hitachi feature that allows specified (usually high access) data sets to be “pegged” or permanently placed in cache memory so they are not managed by the data movement algorithms of the Freedom Storage® system. The Hitachi Flash Access™ feature in the Lightning 9900™ can be used for either S/390 or open systems. Hitachi Flash Access™ is a software utility in the Freedom 9000 Resource Manager™ suite that allows the creating, deletion, and monitoring of data managed by the Hitachi Flash Access™ software. See also Freedom 9000 Resource Manager™.

Hitachi Graph-Track™

Graph-Track™is a software utility in the Freedom 9000 Resource Manager™ suite that allows a robust set of system and network management utilities and provides graphical reports for Lightning 9900™ performance and availability and configuration management.

Hitachi Hi-Star™Architecture

At the heart of the Lightning 9900™ revolutionary design is the Hitachi Hi-Star™

Architecture, which provides multiple, redundant, non-blocking paths between the

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 CruiseControlStorage Maximizer Hitachi SANtinelHitachi Data Systems Professional Services and Support Professional Services OverviewData Protection Services Cost of Risk Analysis methodology CORAData Protection Services Lab Remote Copy Assessment and Implementation ServiceHitachi NanoCopy Implementation Service Hitachi Data SystemsProfessional Services and Support Continuous Availability ServiceOn-lineData Migration Service SAN servicesSoftware Portfolio Review and Analysis Service Hitachi Data SystemsSystem Configurations for the Performance ExperimentHitachi Data Systems The 7700E used all 6GB drivesGlossary of Terms 10BaseT100BaseT ACP pairHitachi Data Systems AvailabilityBack end Business Continuity Planning BCPGlossary CARBCache CHIPHitachi Data Systems Consistency GroupsControl Frame CORA Cost of Risk AnalysisDisaster Recovery GlossaryData Duplication Data Migration Hitachi Data Systems EBCDIC Electronic vaulting ESA/390Glossary FailoverFast Ethernet Fast writeFile Backup Hitachi Data SystemsFICON Front EndHitachi FlashAccess GlossaryHDmS Hitachi CruiseControlHitachi Multiplatform Backup/Restore Hitachi Data SystemsHitachi InstantSplit Hitachi LUN ManagerHitachi Rapid Recovery GlossaryHitachi Resource Manager Hitachi SANtinelHitachi Data Systems HXRC Hitachi Extended Remote CopyHYPERtape JavaLogical Volume GlossaryLightning 9900 Series Logical UnitHitachi Data Systems MBCPMIPS Meta-dataGlossary MTBFMTTR NanoCopyHitachi Data Systems On-linesystemOpen system Operating SystemRecovery Time GlossaryRAID RAID ControllersSwitch Hitachi Data SystemsSCSI SnapshotVirtual Logical Volume Image Manager VolumeGlossary SynchronousWorkload Hitachi Data SystemsWarm site Hitachi Data Systems Worldwide Offices Corporate HeadquartersAsia Headquarters Australia/New Zealand Headquarters
