Tokyo, November 15, 2012 - Hitachi, Ltd. (TSE: 6501) today announced that it will strengthen its Hitachi WAN Accelerator Family lineup which dramatically increases the speed of data transfer among multiple corporate sites. As the first step, on November 19, 2012, Hitachi will begin selling the newly added Hitachi WAN Accelerator Remote Backup Model (hereinafter "Remote Backup Model") that allows high-speed backup between data centers for domestic and overseas telecommunications providers, data center operators, cloud computer service providers and other customers handling so-called "big data."
The Remote Backup Model can transfer 1 terabyte (TB) of data up to 26 times faster*1 than when this product is not used, by improving the transfer performance*2 of a TCP session*3. This speed enhancement will facilitate high-speed backup of large volumes of data between data centers.
The Hitachi WAN Accelerator Family uses an proprietary Hitachi algorithm to measure the packet loss ratio as well as its fluctuation, and in real time estimates the available WAN bandwidth and optimizes the data transfer speed. To achieve high-speed data communication, it maximizes the use of physical WAN bandwidth. Hitachi is targeting the Hitachi WAN Accelerator High-end Model (hereinafter "High-end Model") at companies that are expanding their businesses globally. This product will dramatically increase the transfer speeds of large volumes of data between distant locations such as between overseas bases. The High-end Model yields productivity gains for companies by increasing the sharing speed for frequently updated data, such as CAD (Computer-Aided Design) data over long-distances.
The Remote Backup Model that Hitachi has announced will increase the data transfer time from 300 Mbps*4 hitherto to 1 Gbps, enabling high-speed backup of large-volume data between data centers.
Data stored in data centers is growing exponentially year after year. Moreover, advances in cloud computing are encouraging more companies to use data centers. As a result, the negative impact of data loss at a data center caused by a major natural disaster or other event is potentially magnified. For these reasons, demand is increasing for sharing and backing up large volumes of data between data centers as a disaster recovery strategy.
However, backing up large volumes of data remotely is difficult because it takes time to transfer data via WANs. This is the reason why data is often backed up and stored within a single data center. In such a case, all data, including the back-up data, could be lost in the event of a disaster.
Hitachi is providing the Remote Backup Model for high-speed backup between data centers in order to provide a solution to the above issue.
As a second step to augment its product lineup, Hitachi also plans to launch sales of an "Office Model" (tentative naming) for network bandwidth between 10M and 100Mbps in the first half of the fiscal year 2013. This product will facilitate high-speed transfers between data centers and offices, and will enable large volumes of data, such as CAD data, e-commerce data and financial databases at data centers to be quickly accessed from each remote site.
With the Remote Backup Model for handling large volumes of data, the existing High-end Model and the planned Office Model, Hitachi is helping to achieve high-speed data transfer that is customized to various applications by continuously strengthening its product lineup.
The Remote Backup Model is a model that combines a high-speed transfer processing section and an interface section. The WAN Accelerator function is handled by the high-speed transfer processing section to substantially increase the maximum TCP session performance from 300 Mbps with the existing High-end Model to 1 Gbps with the Remote Backup Model, thereby enabling the remote backup of large volumes of data. This allows faster transfer of large data volumes, and greatly reduces the time required for remote backup between data centers.

The Hitachi WAN Accelerator Family uses a proprietary Hitachi algorithm to measure the packet loss ratio and estimates the available WAN bandwidth and optimizes data transfer speed in real time. To achieve high-speed data communication, it maximizes the use of physical bandwidth of the WAN line. This allows users of remote backup between data centers to switch from dedicated lines to low-cost wide-area Ethernets with packet loss. It allows high-speed, high-quality remote backup, which in turn allows savings in communication costs.
