VMware supports both file and block storage. Through vSphere, which includes the ESXi hypervisor, VMware provides features and APIs which offer an abstraction layer for physical storage resources to be addressed, managed, and optimized in a virtual environment.
VMware vSphere allows you to create logical containers called datastores. Virtual machine operating systems and their data are stored in these containers. Datastores can also be used for storing .iso
images, templates and other files.
VMware has its own storage system format known as the Virtual Machine File System (VMFS). VMFS can be deployed on a SCSI-based local or networked storage device such as a SAN device. NFS is a filesystem from the *nix world and can be deployed on a NAS device.
VMFS allows multiple vSphere servers to access shared virtual machine storage concurrently and enables virtualization-based distributed architectures to operate across a cluster of vSphere...
