The generalization of broadband networks has enabled HD video to be delivered over IP networks. However, due to the challenges of a growing customer base as well as customer expectations in terms of video quality, the workload of video delivery services has been greatly increased. Service providers are faced with an increase of the amount of equipments necessary to handle video delivery, leading to equipment and management cost increase, as well as a serious environmental impact of the service because of the high power consumption of the equipment used.
In response to this demand, Hitachi has developed an I/O control technology (real-time OS) for optimizing storage performance for streaming, which improves video delivery performance by fully utilizing the capabilities of the underlying hardware. Hitachi has implemented a prototype of a streaming-optimized storage with this technology based on Hitachi midrange storage product, and measured that this prototype can deliver up to 12Gbps of video data (1,200 streams of 10Mbps HD video).
Hitachi presented this technology at the 19th International Workshop on Network and Operating Systems Support for Digital Audio and Video (NOSSDAV'09), which was held from June 3rd to 5th 2009, in Williamsburg, USA (VA).
