| Shared block storage for databases and VMs | An enterprise SAN array over Fibre Channel or NVMe/FC |
|---|---|
| Use existing Ethernet | iSCSI or NVMe/TCP on a dedicated storage network |
| Highest availability | A high-end array with synchronous replication |
| No physical SAN | A software-defined or virtual SAN on server storage |
| Heterogeneous arrays | Storage virtualisation such as DataCore |
| File sharing | NAS, not SAN, or a unified platform that offers both |

Quick answers.
A SAN is a dedicated high-speed network that gives servers block-level access to shared storage arrays. Servers see the storage as local disks, while it is pooled and managed centrally.
A SAN delivers raw block storage over protocols such as Fibre Channel and iSCSI, so servers format it themselves. NAS delivers files over protocols such as NFS and SMB. Many modern arrays can provide both.
Fibre Channel is a dedicated, lossless fabric that is common in large enterprises. iSCSI runs over standard Ethernet and is cheaper to start. NVMe over Fabrics is now an option on both.
NVMe over Fabrics carries the NVMe command set across a network, over Fibre Channel, RDMA or TCP, giving lower latency than SCSI-based protocols.
For small environments, simple file sharing or cloud-native workloads, a SAN can be costly and complex. NAS, hyperconverged infrastructure or cloud block storage may fit better.
