Standard Redundant Fans for Cooling

The Lightning 9900™ provides fully redundant fans for uninterrupted cooling to all components of the system. The speed and operation of these fans are monitored by the environmental monitoring system. If a fan should fail, it can be “hot swapped” without disruption to the cooling system.

Unmatched Competitive Advantage in RAID Choices

The flexibility in choice for Lightning 9900™ Series RAID protection for disk drives is unmatched. It is important to have choices in RAID protection since files and data have different characteristics in terms of user required performance, uptime, and rebuild times. RAID-1+ (mirroring) offers the highest performance (read from either disk in the mirror pair) during normal operation. RAID-1+ also offers the highest performance in the event of a failed disk since it is not necessary to read parity (and then data) in the event of a disk failure in other RAID configurations.

The Lightning 9900™ Series also offers the capability to intermix RAID levels within a system, depending on the level of availability and performance required by the data hosted on the Lightning 9900™ Series system. For example, a single Lightning 9900™ Series system can configure both RAID-1+ and RAID-5.

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 Data Protection Services Professional Services and SupportProfessional Services Overview Cost of Risk Analysis methodology CORA Hitachi NanoCopy Implementation Service Data Protection Services LabRemote Copy Assessment and Implementation Service Hitachi Data Systems On-lineData Migration Service Professional Services and SupportContinuous Availability 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 100BaseT Glossary of Terms10BaseT ACP pair Back end Hitachi Data SystemsAvailability Business Continuity Planning BCP Cache GlossaryCARB CHIP Control Frame Hitachi Data SystemsConsistency Groups CORA Cost of Risk Analysis Data Duplication Disaster RecoveryGlossary Data Migration Electronic vaulting Hitachi Data SystemsEBCDIC ESA/390 Fast Ethernet GlossaryFailover Fast write FICON File BackupHitachi Data Systems Front End HDmS Hitachi FlashAccessGlossary Hitachi CruiseControl Hitachi InstantSplit Hitachi Multiplatform Backup/RestoreHitachi Data Systems Hitachi LUN Manager Hitachi Resource Manager Hitachi Rapid RecoveryGlossary Hitachi SANtinel HYPERtape Hitachi Data SystemsHXRC Hitachi Extended Remote Copy Java Lightning 9900 Series Logical VolumeGlossary Logical Unit MIPS Hitachi Data SystemsMBCP Meta-data MTTR GlossaryMTBF NanoCopy Open system Hitachi Data SystemsOn-linesystem Operating System RAID Recovery TimeGlossary RAID Controllers SCSI SwitchHitachi Data Systems Snapshot Glossary Virtual Logical Volume Image ManagerVolume Synchronous Workload Hitachi Data SystemsWarm site Asia Headquarters Hitachi Data Systems Worldwide OfficesCorporate Headquarters Australia/New Zealand Headquarters
