This document provides an overview of the functionality of and relationship among the Virtual Storage protocols, which provide a means for a client to access, read, and write to virtual storage (for example, a virtual disk file) on a remote server. Virtual Storage protocols can also provide this functionality to multiple clients by using a shared virtual SCSI disk.
This document describes the intended functionality of the Virtual Storage protocols and how those protocols interact with each other. It provides examples of some common use cases. It does not restate the processing rules and other details that are specific for each protocol. Those details are described in the specifications for the protocols and data structures that belong to this group.
