XT2+ Series DISK RECORDER - Version 10.05 - Hardware Technical Reference Manual
Issue
10.05.A
EVS Broadcast Equipment SA – July 2011
21
Calculation:
Maximum SDTI bandwidth / Actual Bandwidth = real time transfers:
110MB/s / 18.4MB/s = 6 real time transfers.
Note: This number is the maximum that the network connection can support.
Of course it is also necessary that the XT2+ where the material is stored has
enough local disk bandwidth to feed the network accesses, on top of its own
local channels (cfr point 4. Max. RT Channels)
To get information on the recording capacity of the servers according to the video
bitrates, refer to section 1.8.4 ‘Recording Capacity for XT2+ Servers’ on page 13.
