Stagebox camera converter and Typhoon Ingest Card lower broadcast video production costs with Ethernet

Question

The broadcast video market is in a transition period between the use of proprietary broadcast-specific networks and Ethernet. The proprietary broadcast video network protocols came into existence because, at the time, Ethernet speeds and standards were not up to the demands of live video production. Now they are. Ethernet-based broadcast networks promise to reduce video production costs by allowing the use of standard Ethernet cabling and switches to ship video from multiple cameras at an event to the production and editing suite. But there’s plenty of equipment already in the field that uses the older broadcast video network standards. Two new products developed by Xilinx Premier Alliance Member CoreEL in conjunction with BBC R&D can adapt existing broadcast equipment to Ethernet networks specifically for venues such as small- and medium-scale sporting events and multi-location live events (like elections).

Answer 1

I haven't the faintest idea. I only use DV, HDV and XDCAM-EX/HD and have never tried it with any (RED) 4K material. I assume it should be sufficient to handle that. But let's be honest, when I increased my raid array from 10 to 12 disks, I did not notice ANY performance gains. The limiting factor must be the PCI-e bus or the Areca controller, that just does not show any improvements from adding a couple of disks. Another thing to consider is that the various benchmark programs widely in use show quite different results.
As an example, here are two images from HD Tune Pro, one for my 2 disk raid0 on the Marvell chip and the other from my 12 disk raid30 array. First of all, HD Tune shows the wrong size, it is not 2199 GB but should be 10000 GB (at least that is what Areca claims as shown in the last picture), second it ONLY performs at around 745 MB/s transfer rate.
The most noteworthy item to look at is the rapid performance degradation of this raid0 when the disks get fuller. An average transfer rate of 165 MB/s is quite acceptable for a 2 disk setup, but seeing it go down to below 100 MB/s when the disks fill up is bothersome. It will not allow you to handle uncompressed HD at all.
