Maximum video data rate per channel
The maximum video data rate per channel depends on the Profile XP model, the
number of PFC500 chassis connected, and the number of disk drives in the system.
The Profile XP system accesses the disk array through the PFC500’s RAID Controller
board. As video data rates and number of channels in operation increase, the
bandwidth of a single RAID controller board may be exceeded. Some Profile XP
models require at least two or three PFC500s to satisfy the bandwidth required.
The table shows the minimum storage configuration required for your Profile XP
model for different video data rates.
You can select the video data rate the Profile XP system uses to record the video
signal. When selecting video data rates, be sure not to exceed the total maximum
system bandwidth. Fibre channel transfers, archive operations, and high bandwidth
recording or playout may require that you reduce the data rate on other channels or
operate fewer channels at one time. Although playout and recording take priority over
other operations, exceeding your Profile XP system bandwidth may result in record
or playback problems. For information on setting the video data rate, refer to
“Selecting video quality for a channel” on page 118.
