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™.
