Glossary

Hitachi Dynamic Link Manager™

Dynamic Link Manager is a server-based family of software utilities that 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 V Series system by adding redundant SCSI connections between data servers and RAID systems. Dynamic Link Manager therefore provides increased reliability and performance. Supported platforms include IBM AIX®, Sun Solaris™, and Windows NT®/Windows 2000.

Hitachi FlashAccess™

FlashAccess software 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 Hitachi Freedom Storage™ system. The FlashAccess feature in the Hitachi Freedom Storage™ Lightning 9900™ V Series systems can be used for either IBM® S/390® or open systems. Hitachi FlashAccess is a software utility in the Hitachi Resource Manager™ suite that allows the creation, deletion, and monitoring of data managed by the FlashAccess software. See also Resource Manager.

Hitachi Graph-Track™

Graph-Track is a software utility in the Hitachi Resource Manager suite that enables a robust set of system and network management utilities and provides graphical reports for Lightning 9900 V Series performance, availability, and configuration management.

Hi-Star™Architecture

At the heart of the Lightning 9900 V Series revolutionary design is Hi-Star architecture, which provides multiple, redundant, non-blocking paths between the storage ports, multiple cache nodes, and multiple disk Array Control Processors (ACPs).

Hitachi LUN Manager

LUN Manager is a software utility in the Hitachi Resource Manager™ package that allows for complete systems management of LUNs. See also LUN and Hitachi Resource Manager.

Hitachi Multiplatform Backup/Restore

Multiplatform Backup/Restore software provides channel-based backup/restore of open systems volumes using standard mainframe utilities, which leverage current investment in hardware, software, skills, and procedures. Multiplatform Backup/Restore provides high-performance, high-bandwidth capabilities. One copy of software resides on each controller.
