CCURs architecture has a backplane bandwidth limitation that limits the machine to hundreds of full frame rate MPEG 2 streams. The top end machines have proprietary backplanes (ie ..wide) that allow more concurrent streams from one array. There are ways to "parallel" VoD machines together to get linear scaling but these are tricky and should only be attempted after the core is solid. It is like having 4 PCs dice up a processing job (distributed processing) ... possible in theory but few examples that really work well.

Since a 2 hour movie takes 1.2GB of disk (MPEG2) and your system likely needs to be deep (500-1000 selections) replicating content means replicating disks (as well as a few other things) and thus is usually not cost competitive against machines that can do it without replication. The storage, and the back-up for the storage, are usually over 50% of the VoD server cost. It isn't clear to me if CCUR is providing the storage elements for On Command .... we should have asked them (DAMN!).

I don't know why Omnio signed an exclusive ... they likely did not want others to sign-up with CCUR and steal Omnio's potential market share. Which begs the question, is it an exclusive (CCUR limitted in who they can sell to) or is CCURa single source to them ....Hmmm .....
