Hitachi to Launch WAN Accelerator Family for Dramatically Faster Data Transfer Among Global Offices.

15 Times Faster than Conventional TCP/IP in the United States-Japan-file-transfer Experiment

Tokyo, Jan 11, 2012 - (JCN Newswire) - Hitachi Ltd today announced that it has unveiled 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 volume of data necessary for global operations. Thus it improves the productivities of global banks and manufacturers, such as automobile, steal and semiconductor industries.

There is an increasing demand for transferring large volumes of CAD (Computer-Aided Design) data and the like, 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, so do not effectively improve performance.

Hitachi WAN Accelerator Family is not cache-type solutions, but making the 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.

Highlights of Hitachi WAN Accelerator Family

(1) Efficiency improvements for long-distance data transmission

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.

(2) Monitoring and dynamic control of bandwidth

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 the most of the physical channel bandwidth.

(3) Easy installation without major changes in existing systems

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.
