A Fibre Channel switch with the storage virtualization function (hereinafter called "virtualization switch") is required for using VSC. ESC provides the storage virtualization function by controlling the storage virtualization function engine (hereinafter called "engine") that runs on the virtualization switch.
VSC Manager performs configuration management to form the foundation of the virtual storage function, and handles and supplies processing requests made on the client (GUI) to the engine that runs on the target virtualization switch.
VSC admin client runs on the admin client unit to provide an operation interface related to virtual storage.
The engine, running on a virtualization switch, processes various requests for the virtual disk according to instructions from the Manager. It also controls server access of the virtual disk. However, engine operation has no impact on performance, because it does not interfere with regular read/write data streams.
