Estimating storage capacity
The storage capacity is determined by the number and size of disk drives in system, and
the video data rate selected to record video. The Fibre Channel RAID storage system can
be configured with five to thirty disk drives, including the Expansion chassis.
You can refer the following tables for storage capacity estimates based on the number of
disk drives installed and the video data rate. The estimates in these tables are based on
use of four audio channels and one time code channel per video channel using the 525
video format.
