VSI for vSphere Web Client
Virtual Storage Integrator (VSI) allows you to easily provision and manage EMC ViPR software-defined storage for ESX/ESXi hosts. VSI is an architecture that enables the features and functionality of EMC ViPR™ software-defined storage. Tasks that you can perform with VSI include storage provisioning, storage mapping, and viewing information such as capacity utilization. VSI consists of a graphical user interface and the EMC Solutions Integration Service code (the programming interface within VSI that provides the communications to the storage systems). VSI interacts with:
A web browser
vSphere Web Client Server
EMC Solutions Integration Service
The administrator uses the vCenter to manage and provision storage. VSI interfaces within the vCenter to access the ViPR storage.
The VSI Plugin now comes as a the EMC Integration Service virtual appliance. The appliance provides the interface for the Web Client to communicate with ViPR.
