A registration application that allows a service provider customer that is using data storage resources (storage and/or storage-related services) provided by the service provider to register with a Service Provider Management System (SPMS) that is maintained by the service provider. The registration application executes on each of the customer's servers (that is, those which are connected to resources being used) to produce registration information and provides that registration information to the SPMS. The resources have a scratch pad storage area that is used by the servers and the SPMS to communicate with each other. The registration information is passed to the SPMS by the servers indirectly via the scratch pad area. The SPMS uses the registration information to associate customer information with the resources used by that customer's servers. The association of the customer information and resources can then be used by the SPMS to track customer usage of the resources for billing and other applications.
