Storage Capacity
The Profile Video File Server storage capacity is determined by the number of disk
drives in the system and the selected video data rate used to record the video signal.
The Profile Video File Server storage space can be expanded by adding one or two
PDX 218 Disk Expansion Chassis containing eight 18GB disk drives each.
Table 1-1 shows storage capacity estimates at selected video data rates for a single
PDX 218 containing eight 18GB disk drives
All Profile applications software allows you to select the video data rate used to record
the video signal. For more information about setting the video data rate, refer the
appropriate sections of the Profile Family User Manual.
Storage estimates include 4 channels of audio and 2 channels of timecode. Adding 4
more channels of audio adds approximately 3Mb/s to the total data rate.
