Lightning 9980V System Array Frames
Each array frame of the Lightning 9980V system contains up to 256 Hard Disk Drive
(HDD) modules and communication interfaces to the Control Frame, for a total of 1024
drives for a maximum configured system. An Array Frame is shown in Figure 9.
This design allows for efficient centralized and consolidated storage, which results in
reduced management costs and lower overall TCO.
The Lightning 9900 V Series power systems consist 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, if a power supply fails during operation, the failed power can be
dynamically removed without any loss to system operation. The Lightning 9900 V Series
power supply modules are shown in Figure 10.
