Hitachi 9900 User Manual

Cables carry 48-volt main system power from the back of the Control Frame and Array

Frame where the power is converted to the required voltages.

Different AC power cord options allow all Lightning 9900 V Series models to connect

with the different electrical outlet configurations used around the world.

Although the Lightning 9980V system has the ability to be upgraded from one to four

array frames, the Lightning 9970V

™

system is a fixed-configuration, single-cabinet storage

system. The Lightning 9970V system is targeted for IT environments where floorspace is at
a premium and data growth is limited, yet where premium storage functionality is required.
From the front, the Lightning 9970V system looks very much like the Control Frame of a
Lightning 9980V model. However, the back end contains HDD arrays housing up to 128
disks in a 73.2 inch high, 30.8 inch wide, and 31.5 inch deep footprint. This is shown in
Figure 11.
