Hyper-Converged solutions featuring all-flash storage are the future as they continue to decrease in cost and offer dramatically better performance when compared to magnetic disks. Virtual SAN is optimized for modern all-flash storage with efficient near-line deduplication, compression, and erasure coding capabilities that lower TCO.
Deduplication and compression enable considerable capacity savings across the entire Virtual SAN cluster — especially in environments where standard OS builds (templates and clones) are used and where there is abundant data commonality such as file shares. RAID-5/6 erasure coding reduces capacity consumption by as much as 50% versus RAID-1 (mirroring) with the same levels of availability for FTT=1 and FTT=2 Virtual SAN rule sets.
