The vSAN presents a robust, secure, and efficient shared datastore to all nodes within a VxRail cluster. External SAN storage is typically not part of a VxRail environment. However, often a requirement exists to access external storage in order to move virtual machines and data into a VxRail environment or move data between environments. Fibre Channel SAN connectivity is supported, and so is IP-based storage. An important distinction is that data in the Fibre Channel, iSCSI or NFS datastore is self-contained and is not distributed to the disk groups within the VxRail cluster.
