Hitachi 9900 Series - Manual (Page 18)

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 ™ Series models to connect
with the different electrical outlet configurations used around the world.
Model 9910 Packaging
Although the 9960 has the ability to be upgraded from one to six array frames, the
Lightning 9910 is a fixed-configuration, single-cabinet storage system. The 9910 is targeted
for IT environments where floorspace is a premium and data growth is limited, yet where
premium storage functionality is required. The 9910 looks very much like the Control
Frame of a Lightning 9960. The back end contains four HDD arrays housing up to 48
disks in a 70.5 inch high, 27.6 inch wide, and 31.5 inch deep footprint. This is shown in
Figure 7.
