An Overview of the Lightning 9900 V Series Architecture

The Lightning 9900 V Series intelligent storage systems are the most powerful enterprise systems in the industry today and two generations ahead of the competition. The new architecture used in the Lightning 9900 V Series has almost twice the internal processing power and bandwidth of our earlier enterprise systems. Figure 2 illustrates the architecture of the Lightning 9900 V Series.

At the heart of the Lightning 9900 V Series is enormous capacity for throughput, thanks to Hi-Star architecture. This network of interconnecting high-speed links to system components provides an unequaled internal aggregate bandwidth of 15.9GB/sec (gigabytes/sec) in the Lightning 9980V system. This bandwidth is divided into 10.6GB/sec for data transfer and 5.3GB/sec for separate internal control information transfer. This superhigh bandwidth is approximately 10 times that of competitive products.

The Lightning 9980V system has almost twice the processing power of our earlier enterprise systems.

Figure 2 – The Lightning 9900 V Series is based on an internal switched architecture.

The Lightning 9980V system has an internal bandwidth of 15.9GB/second.
