The transfer rate should be slightly above the video input bit rate for the the
SGI Media Server. The example above (32000000) represents approximately 1.2 times the
real-time rate for a single DVCPRO 25 video stream.
The number of FTP transfers set by the vtr.ftp.procs.max control plus the total
number of active video codecs defines the number of concurrent data streams under
SGI Media Server control. This value, when multiplied by the number the value of
control vtr.ftp.io.rate.default, determines the peak bandwidth of the XFS
real-time filesystem in megabits per second. The following formula shows this
symbolically:
max-bandwidth = (vtr.ftp.procs.max + #active_codecs) * vtr.ftp.io.rate.default
The capacity requirements for the filesystem resource can be tuned to suit this
anticipated load.
