Hitachi recently announced a new WAN Accelerator that serves as high-speed big data backup between data centers for domestic and overseas telecommunications providers, data center operators, and cloud computer service providers.
The device promises to reduce the required time for remote backup for 1 TB of data from more than 58 hours to about 2.25 hours.
According to the manufacturer, the speedup is due to a proprietary algorithm to measure the packet loss ratio as well as its fluctuation. Hitachi said that the technology can estimate the available WAN bandwidth and optimize the data transfer speed accordingly.
Initially, Hitachi is offering a high-end version of its Remote Backup Model, which features a maximum of 6,000 TCP sessions, a maximum TCP session performance of 300 Mbps, as well as an optimized WAN bandwidth of 1 Gbps. A lower-end "office" version will be added in April 2013, providing up to 2,000 TCP sessions.
