At the Cable-Tec Expo in Denver last week, Arroyo Video Solutions, a company that specializes in offering VOD servers based on industry-standard hardware, unveiled scalability enhancements which it says it achieved by combining its Linux-based, video networking software with IBM System x366 products: according to the company, the combo delivers over 80,000 streams per rack, which it claims is double the density of competing systems. Arroyo says that the combo allows any number of servers and racks to be networked together within a metropolitan, regional or national topology, effectively creating one large virtual server with unlimited scalability. At the Cable-Tec show, Arroyo demo’d its software running on five IBM System x366 servers interconnected by a Cisco Catalyst 7606 switch equipped with 20 10-Gigabit interfaces; the solution supported 30,000 simultaneous MPEG-2 streams. "As personalized TV services such as nPVR begin mass market deployment, operators need the scalability to deliver a stream to every home as well as to expand their ability to ingest and store increasing volumes of programming," Arroyo president and CEO, Rick DeGabrielle, said in a prepared statement. "With Arroyo’s video networking software running on IBM systems, we’ve not only raised the bar with respect to stream density, but we can take any number of servers, distribute each where it makes the most sense within the network, and manage them all as a single, cohesive unit. The result is a ‘virtual server’ that encompasses the entire network and provides unlimited scalability. Our solution is unique in that it does for video what has previously been applied only to voice and data. You can’t do that with proprietary standalone servers."
