FlexRAID

What is FlexRAID?

FlexRAID is a highly scalable and smart storage system that turns independent hard drives of various sizes, makes, and models into storage pools and storage pools into storage clouds.

Additionally, FlexRAID provides both snapshot and real-time parity data protection with support for RAID4, RAID6, and RAIDX where X is any number of tolerances desired. Parity data protection can be configured at the storage pool level and/or at the storage cloud level.

Furthermore, FlexRAID is not limited to hard disks as it can pool data from all accessible sources including removable media, external storage, network shares, LUNs, disk arrays, etc.
