Executive Summary: A researcher needs to create a data collection on a storage resource and share the collection’s use and management with a community of researchers who are using many resources.
No effort or changes are proposed at this time.
|Component’s role in the capability
|Globus Connect Personal
|Researchers who wish to use Globus to move data to/from a Service Provider's mass storage via a Globus interface can do so by installing Globus Connect Personal on their personal (laptop or desktop) system, which provides Globus a way to move data to and from their personal system.
|Globus Connect Server
|Some SPs offer Globus interfaces for accessing their mass storage systems, which they provide by installing the Globus Connect Server software on their data transfer nodes. These interfaces allow researchers to access data in the mass storage system without logging into the SP's command-line login services. Campus IT administrators can also install Globus Connect Server on shared campus systems to enable data transfers to and from those systems. Globus Connect services are accessed via the Globus Transfer Web application (in a Web browser) or via an installation of the Globus command-line interface (CLI) or software developer kit (SDK) on the researcher's local system.
|Globus Toolkit GridFTP Service
|Some Service Providers (SPs) offer GridFTP access to their mass storage systems, allowing researchers to access data in the storage systems without logging in to the SP's command-line login services. GridFTP access is via a GridFTP client application installed on the system being used by the researcher.
|When Service Providers (SPs) provide Globus access to their mass storage systems, researchers can transfer data on those systems to other XSEDE, personal, campus, or research laboratory systems via the Globus Transfer service.
|Service Provider Mass Storage Systems
|Mass storage provided by Service Providers (SPs) is the key ingredient for all XSEDE data management use cases because it is the only source of storage within the XSEDE system. (An important alternative available to researchers is commercial cloud storage, but this capability deliver plan focuses on XSEDE's implementation.) SP mass storage is nearly always available from the SP's computation systems, as described in the main use case, but some SPs provide alternate network interfaces as described in Variation 1 of the use case.
|The XSEDE Single Sign-On Hub (SSO Hub) provides a single point of access for Service Provider (SP) login services. Users can login to the SSO Hub using XSEDE credentials and then login to one or more SP login services without additional credentials.
