XT2+ Series DISK RECORDER - Version 10.05 - Hardware Technical Reference Manual

Issue

10.05.A

EVS Broadcast Equipment SA – July 2011

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.
