          SI5: Abstraction layer that supports data replication systems

          SI5 Report [PDF 105Kb]. 

          SI5 concerns the development of a higher level abstraction for replication services, called the Grid Replication Framework (GRF). The GRF allows the user to interact with a single API, but use several different replication services. It has a flexible modular design for supporting new replica clients. With this plug-in design, users can easily develop clients for GRF that add data access supports for other systems.

          Overview

          The Storage Resource Broker (SRB) is a data management system that employs a client-server architecture. It provides mechanisms to access data based on some attributes other than filenames. SRB uses a MCAT (Meta data Catalog) service to store meta data information for the stored datasets. Such information is used to identify and describe the associated data. Users of SRB can access the data using the command line clients called Scommands. Other means including a web portal called MySRB, and a Windows-based client called inQ. There are also APIs in C, Java and Python. SRB also provides two libraries, SrbIO and UnixIO, to facilitate code modification for legacy programs.
