Which storage protocol is supported by vSphere?

vSphere supports the NFS (Network File System) protocol, which is a widely used file-based storage protocol for sharing files over a network. NFS allows multiple servers to access shared storage, enabling better resource utilization and data accessibility within a virtualized environment. It's particularly advantageous in VMware environments for facilitating storage offerings such as NFS datastores, which can be used for hosting virtual machine files, storing templates, and providing shared access among multiple ESXi hosts.

NFS is favored in many scenarios because of its performance, simplicity in setup, and its ability to work seamlessly with VMware’s storage features, such as vMotion and High Availability. Unlike the protocols present in the other options, NFS is specifically optimized for the types of workloads commonly found in virtualized datacenters.
