Chapter 3 Working with RAID Storage Using GVG Disk Utility

Determining maximum video data rate per channel
The maximum video data rate per channel depends on the number of video channels in
operation, the video data rate used, and the number of disk drives in the RAID storage
system. You can select the video data rate the Profile XP system uses to record the video
signal. For information on setting the video data rate, refer to “Selecting video quality
for a channel” on page 158.
When selecting video data rates, be sure not to exceed the total maximum system
bandwidth. Keep in mind that Fibre channel transfers, archive operations, off-speed
play, 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.
If you are unsure about maximum video data rate per channel or your Profile XP
available system bandwidth, consult your Grass Valley support representative. Be
prepared to supply the number of video channels, the usual bit rate, uncompressed VBI
usage, the number of audio channels, typical video network loads, and all the other
factors that are used to calculate maximum data per channel and the number of storage
disks required.
NOTE: The information in the following sections do not apply to Profile XP media
platforms connected to an Open SAN.
Connecting RAID chassis cabling
The Installation Guide for your PVS Series model provides complete information on
connecting your RAID storage chassis to the Profile XP system using both single and
redundant RAID controllers. It also describes how to set Fibre Channel Loop address
and Chassis ID for the RAID storage and the Expansion Chassis.
