storage ports, multiple cache nodes, and multiple disk Array Control Processors (ACPs). Each path runs at 100MB/s, permitting the Lightning 9900™ to scale up to a total bandwidth of 6.4 GB/s. This is six-to-eight times the internal bandwidth of shared bus based storage systems. For redundancy and performance, Hi-Star™consists of four cache switches that are cross-connected to four cache modules and two control memory banks. These control memory banks contain addressing and control information and are also cross-connected to front-end storage ports and back-end disk array ports.

Hitachi InstantSplit

Hitachi InstantSplit is an enhancement to ShadowImage™ that provides multiple copies of data against which new applications can be tested or data mining queries can be run even before (newly created) ShadowImage™ pairs have been fully synchronized. With InstantSplit™ and the Lightning 9900™ bottleneck-free performance, applications can be deployed faster, resulting in the faster delivery of products to market and better-targeted sales campaigns. See also ShadowImage™.

Hitachi LUN Manager

Hitachi LUN Manager is a software utility in the Resource Manager 9000™ suite that allows for complete systems management of LUNs. See also LUN and Resource Manager™ 9000.

Hitachi Multiplatform Backup/Restore

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

Hitachi RapidXchange™

Hitachi RapidXchange™ provides for the file conversion and exchange of data between S/390® and open systems hosts. Hitachi Multiplatform Data Exchange provides file access library software for open systems hosts and runs on the following host servers: HP/UX®, AIX, Sun Solaris®, Compaq Tru64™, UNIX®, Sequent DYNIX/ptx®, SGI IRIX®, NCR UNIX® SVR4, Windows NT®, and Windows 2000®.

Hitachi Multiplatform Resource Sharing

Hitachi Multiplatform Resource Sharing is built right into the Lightning 9900™. With Hitachi Multiplatform Resource Sharing, Lightning 9900™ users can share resources between UNIX®- or Windows NT®/2000-based servers and S/390® mainframe platforms. Sharing resources across heterogeneous platforms lowers total cost of ownership, provides a centralized point for data management, and simplifies the management of heterogeneous systems..
