What is Grid File Replication Manager?
Grid File Replication Manager (GFRM) is a Web-based tool for managing replicas on the data grid.
In a grid environment, it is often desirable to create remote, read-only copies (replicas) of files. Replication can be used to reduce access latency and improve data locality. Replica Location Service (RLS) is a system developed by the open source grid community to maintain and provide access to information about the physical locations of copies. Grid File Replication Manager builds on top of RLS to provide a Web-based tool for managing replicas on the grid. In addition, it provides an easy mechanism for creating and searching through entries in RLS.
How does it work?
GFRM binds standard grid components to provide a reliable replication service. It presents a user-friendly interface that simplifies the current means of managing grid data, as follows:
- Users enter search criteria for replicas.
- GFRM queries RLS for infomation on the resulting replicas.
- Users are then able to perform various tasks such as replicate, add or delete RLS entries, view properties, and add, delete, or change attributes.
- If asked to replicate, GFRM selects a replica and initiates replication through third-party transfer. If RLS is running on the destination, GFRM creates mappings on the RLS server.
- Users also have the option to publish single or multiple files to the RLS server in a single step.

Scott Colbeck is an associate software engineer who has worked at IBM for five years. He spent three years developing SCSI and Fibre Channel command processing for Shark. After Shark, he spent about a year and a half with the Storage Software Strategy team on prototypes of grid technology, I/O throttling, and a caching algorithm. Currently, Mr. Colbeck is working on a storage virtualization product for automating basic storage management tasks.
Vandana Gupta is a staff software engineer in the Storage Software Development group. She received her B.E. (1998) in Computer Engineering from University of Pune, India, and M.S. (2000) in Computer Science from the University of Nebraska-Lincoln. Since graduating, Ms. Gupta has worked on various products and prototyping activities in IBM. This technology was co-developed by her as a member of Storage System Technology Institute at IBM. Her current focus is on automating Storage Provisioning through workflows to be delivered as part of TotalStorage Productivity Center, which is IBM's latest product designed to help reduce the effort of managing complex storage infrastructures.
