In-memory de-duplication technology to accelerate response for large-scale storage
Fujitsu Laboratories today announced the development of a high-speed in-memory data deduplication technology for all-flash arrays, which are large-scale, high-speed storage systems and use multiple flash devices such as solid-state drives. This technology enables the production of storage systems with up to twice the response speed when writing data, compared to previous methods. In recent years, all-flash arrays have incorporated deduplication technology that consolidates duplicate data into one to write to a flash device, in order to utilize the limited capacity of flash devices. However, as the system connects to multiple flash devices through a network in order to search for duplicate data each time it writes data, and storage devices grow in capacity and increase in speed, a problem of lowered response speed during write operations arises.
