storage system in the industry today. The new architecture used in the Lightning 9900
Series is specifically designed for the brutal I/O demands of open systems environments.
Extremely high internal bandwidths, high-speed back-end design, scalable internal
pathways, increased processor speeds, and increased number of processors, larger cache sizes,
and a new and improved high-performance RAID-1 (called RAID-1+) sets the Lightning
9900 Series apart from all other storage systems. Figure 2 illustrates the architecture of the
