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.
