Virtual Storage Area Network
VSAN is a hyper-converged, software-defined storage product that pools together direct-attached storage devices across hosts to create a distributed, shared data store. It maximizes the use of hardware resources while providing high performance.
- • VSAN eliminates the need of dedicated physical storage by mirroring internal disks between servers.
- • Create a fault-tolerant storage pool across servers.
