Kasenna upgrades servers with 64-bit Linux
Kasenna has announced advances in their VOD systems. By developing its own high-performance I/O enhancements to the Linux kernel and capitalizing on advances in Intel’s processor and system architecture, Kasenna has ported its MediaBase platforms to 64-bit processing architecture. This design 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 3.2Gb/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 1 RU server or 60,480 streams per 42 RU rack. Using a hybrid system of disk-based clusters and RAM-based clusters and its patent-pending Stream Clustering technology, Kasenna has achieved new densities in streaming performance.
Leveraging a 64-bit architecture, such performance from the server enables advanced services such as network-based Personal Video Recording (NPVR) at the headend or central office. These capabilities open doors for telcos, cable operators and next-generation broadband service providers to deliver compelling offerings that attract new customers, reduce customer churn and increase revenues. Kasenna’s highly available, clustered architecture also enables operators to separate storage from streaming capacity, putting greater processing power behind the streaming application for faster delivery.
Products based on 64-bit Intel Xeon systems and a 64-bit port of Kasenna’s server platforms will be available to customers beginning Q2 2005.
