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
