Model 9960 Array Frames

Array frames 1-4 of the 9960 contain up to 96 Hard Disk Drive Assemblies (HDDs) and communication interfaces to the Control Frame. Array frames 5-6 contain up to 64 drives for a total of 512 drives for a maximum configured system. An Array Frame is shown in Figure 5.

This design allows for efficient centralized and consolidated storage, which results in reduced management costs and lower overall total cost of ownership.

The Lightning 9900™ Series power subsystem consists of redundant power supplies in both Control Frames and Array Frames. The power supplies are both hot pluggable and hot swappable and are N+1 redundant. This means they can be removed or installed during system operation and that if a power supply fails during operation, the failed power can be dynamically removed without any loss to system operation. A Lightning 9900™ Series power supply module is shown in Figure 6.
