Nexenta Systems, the five-year-old open storage player, has come up with in-line deduplication for primary or production storage including virtualized storage, calling it a first. It means more data can be stored on a server by reducing duplicate data, a winnowing process usually reversed for backup and replication, and should cut pricey high-speed proprietary storage needs. The widgetry’s in the NexentaStor 3.0 upgrade of the start-up’s enterprise-class storage solution, which is based on Sun’s open source Zettabyte File System (ZFS), and Nexenta’s own Virtual Machine Datacenter (VMDC) 3.0, a new release of its virtualization management platform. NexentaStor 3.0 also includes support for Microsoft Hyper-V, making it the only storage solution to support all the major virtualization environments and it does it from a unified VMDC environment. VMDC can also be used to clone a virtual desktop for hundreds of users.
