Kasenna offers 64-bit video server platforms

Kasenna has ported its MediaBase platform to a new 64-bit processing architecture. Stating that the port sets a new standard for next-generation VOD systems while lowering the cost of ownership, the manufacturer said it developed its own high-performance I/O enhancements to the Linux kernel and capitalized on advances in Intel’s processor and system architecture.

In addition to industry-leading performance, Kasenna said 64-bit port delivers better space utilization, higher switch port densities and increased reliability for cable MSOs and Telcos deploying advanced on-demand services.

Using the 64-bit capability of Intel Xeon processors, Kasenna MediaBase achieved 3.2 Gb/s of streaming throughput and (853 streams at 3.75Mb/s) from a dual-CPU, 3RU disk-based server. The Kasenna system delivered 5.4Gb/s from a 1RU RAM-based server.

At the CableLabs specification of 3.75Mb/s for streaming video, this amounts to 1440 streams per 1RU server or 60,480 streams per 42RU rack. Using a hybrid system of disk-based clusters and RAM-based clusters and its patent-pending Stream Clustering technology, Kasenna said it has achieved breakthrough densities in streaming performance.
