About the datastores in Veritas InfoScale Operations Manager
A datastore is a collection of physical storage that is created based on the disks and LUNs that are attached to an ESX server. The storage is assigned to VMware virtual machines from the datastore. Veritas InfoScale Operations Manager lets you view the storage mapping between the datastore and the virtual machines.
A datastore is a storage location for virtual machine files. This storage location can be a VMFS volume or a directory on an NFS file system.
Also, VMware can assign storage to the virtual machines directly from the physical disks that are available with the ESX servers. This storage assignment is known as Raw Device Mapping.
