Tokyo, January 11, 2012 - Hitachi, Ltd. (NYSE: HIT/TSE:6501) today announced that it has unveiled a WAN Accelerator Family for global data centers, and for enterprises with global R&D, design, and manufacturing operations. The initial model goes on sale worldwide from January 12, 2012.
Hitachi WAN Accelerator Family speeds up international transfers of large volumes of graphical design data and the like - by minimizing the performance impact of packet losses and round-trip delays on global Wide Area Networks (WANs). It makes it possible in less time to share and update large volumes of data necessary for global operations. Thus it improves the productivity of global banks and manufacturers, for example in the automobile, steel and semiconductor industries.
There is an increasing demand for transferring large volumes of data, for example for CAD (Computer-Aided Design) and other areas, among overseas offices. However, the commonly-used conventional TCP/IP protocol is not efficient over long-distance global links - its throughput is severely impacted by round-trip delay and packet losses. Commonly-used content-cache technologies also waste bandwidth when delivering large volumes of frequently-updated data, and therefore are not effectively improving performance.
The Hitachi WAN Accelerator Family is not a cache-type solution, and instead makes best use of the physical bandwidth of communication channels, reducing the time to access data updates, and thus improving productivity of global companies significantly.
Leading global companies are thus highly motivated to use such reliable high-speed communication technologies to accelerate large-data transfers, or to expand their private-enterprise cloud services worldwide.
By using an innovative Hitachi algorithm for performance improvement, the products minimize performance degradation associated with long round-trip times and packet loss over global channels, and improve the throughput of TCP sessions.*1

Hitachi WAN Accelerator Family measures packet loss ratio in real time, estimates the available bandwidth, and optimizes data transfer speed on a real-time basis. To realize high-speed data communication, it makes most of the physical channel bandwidth.
The Hitachi WAN Accelerator Family can be installed at both ends of circuits in the existing systems, without changing network design or client terminal and server applications.
From June 2009, Honda R&D Co., Ltd., Hitachi, and Hitachi High-Technologies Corporation ("Hitachi High-Tech") have jointly researched technologies to significantly improve the data transfer speed over WANs. Honda R&D Co., Ltd. initially started its research on global high-speed data exchange to improve its productivity. Hitachi decided to join the research to meet the needs of the automotive industry. The results of the joint research have been implemented into the products.
Hitachi starts to sell the Hitachi WAN Accelerator Family in Japan, the United States, and Europe. Hitachi plans to promote the business globally by expanding the sales area (outside these initial three regions) in the future, and is committed to enhancing the products in response to new requirements of customers and markets. And Hitachi continues to contribute to big data solutions in enterprises worldwide by providing higher-speed data-transfer technologies that are particularly important in cloud services.
On February 28 and 29, 2012, Hitachi WAN Accelerator Family is to be exhibited at Cloud Days Tokyo 2012.
The following figure shows an example of the deployment of Hitachi WAN Accelerator Family in an enterprise cloud service to realize fast data transfer among R&D, design, and manufacturing sites, and to realize fast data backup service in distributed data centers.
