MediaBase XMP with Advanced RAM-Based Streaming Option Delivers 40,000 3.75 Mbps VOD Streams in a Single Linux Rack

November 16, 2004, London, UK— Kasenna, the acknowledged market leader in broadband video solutions, has announced the introduction of its patent-pending High Performance Streaming (HPS) technology, an advanced option to its MediaBase™ XMP video server platform. MediaBase XMP and HPS software enables the newest product in Kasenna’s field-proven line of video servers, the RAMBase™ video server. RamBase provides industry-leading stream density of over 40,000 streams per-rack, all on off-the-shelf hardware utilising the latest Intel® Xeon™ processors with Intel® Extended Memory 64 Technology (Intel® EM64T).
Available for testing immediately, the new RAMBase is a 1RU device that supports up to 1000 video streams using four Gigabit Ethernet ports. Through its integration with Kasenna’s Stream Clustering technology, RAMBase can quickly be deployed as a high-performance cache option extension to any MediaBase server cluster and extend the company’s existing near-linear scalability to dramatically reduce the operator’s cost to deploy VOD services . RAMBase servers with various storage capacities will ship in Q1 2005.
“With the addition of HPS and RAMBase to our product offerings, Kasenna brings to the market not only advanced technologies on mainstream platforms, but also a proven and time-tested server solution for high-performance streaming,” said Kasenna CEO and Chairman Mark Gray. “As video on demand deployments grow in size and scope, RAMBase will help our customers scale their networks in the most cost-effective way.”
RAMBase enables hybrid RAM/disk-based streaming clusters that combine the performance and reliability of RAM-based servers with the capacity of disk-based servers at a far lower cost than exclusively using RAM-based streaming servers. With RAMBase, service providers can easily extend the capacity and performance of their MediaBase XMP server clusters by sharing content assets, balancing subscriber traffic loads and providing fail-over redundancy. Kasenna’s large scale streaming clusters are built using standard server components, not proprietary hardware design. This means server providers utilise off-the-shelf server hardware for VOD rather than costly components that can quickly become outdated and difficult to support.
“Kasenna’s in-memory video caching technology in RAMBase running on Intel Xeon processors with Intel EM64T enables powerful new solutions such as video streaming for the service provider market,” says Melissa Laird, general manager of Intel’s Solutions Enabling Division.
“HPS is more than delivering popular titles from RAM,” said Dr. Satish Menon, CTO of Kasenna. “By implementing a system-wide approach to scalability, Kasenna has addressed the need to dynamically move content through cache hierarchies as titles become popular. As operators begin to deploy massive VOD libraries, migrating these popular assets to a RAMBase server enables service providers to cost-effectively offer a wide variety of titles.”
“RAM caching will improve the performance of content delivery networks,” said Michelle Abraham, director of media research at In-Stat/MDR. “By adding a RAM cache option to its MediaBase XMP server line, Kasenna is offering its customers a more effective way to manage their network and a lower overall cost of ownership.”
