Storage Resource Broker(SRB) isdata gridmanagementcomputer softwareused incomputational scienceresearch projects. SRB is a logical distributedfile systembased on aclient-server architecturewhich presents users with a single global logical namespace or file hierarchy.[1]Essentially, the software enables a user to use a single mechanism to work with multiple data sources.
Description
editSRB provides a uniform interface to heterogeneouscomputer data storageresources over a network. As part of this, it implements a logicalnamespace(distinct from physical file names) and maintainsmetadataon data-objects (files), users, groups, resources, collections, and other items in an SRBmetadatacatalog (MCAT) stored in a relationaldatabase management system.[2]System and user-defined metadata can be queried to locate files based on attributes as well as by name. SRB runs on various versions ofUnix,Linux,andMicrosoft Windows.
The SRB system ismiddlewarein the sense that it is built on top of other major software packages (various storage systems, real-time data sources, a relationaldatabase management system,etc.) and it has callable library functions that can be utilized by higher level software. However, it is more complete than many middleware software systems as it implements a comprehensive distributed data management environment, including various end-user client applications. It has features to support the management and collaborative (and controlled) sharing, publication, replication, transfer, and preservation of distributed data collections.[3]
SRB is sometimes used in conjunction with computationalgrid computingsystems, such as Globus Alliance, and can utilize the Globus Alliance Grid Security Infrastructure (GSI)authenticationsystem.
SRB can store and retrieve data in archival storage systems such as theHigh Performance Storage Systemand SAM-FS, on diskfile systems(Unix, Linux, or Windows), asbinary large objectsor tabular data in relationaldatabase management systems,and on tape libraries.
SRB was used since 1997. In 2008 the SRB was estimated to be managing over two petabytes of data.
While licensed, SRB source distributions are freely available to academic and non-profit organizations.NirvanaSRB, a commercial version of SRB, featured capabilities specifically adapted to government and commercial use.[4]
History
editSRB development began in 1995, through the cooperative efforts ofGeneral Atomics,the Data Intensive Cyber Environments Group (DICE), and theSan Diego Supercomputer Center(SDSC) at theUniversity of California, San Diego(UCSD) with the support of theNational Science Foundation(NSF).
SRB builds on the work of Reagan Moore. Moore, a doctorate in plasma physics from UCSD and former computational plasma physicist at General Atomics, joined the San Diego Supercomputer Center at its inception.[5] A project for a distributed object computation testbed was funded byDARPAand theUS Patent and Trademark Officein 1998 and 1999.[6]
In 2003,General Atomicswas granted an exclusive license from UCSD to develop SRB for commercial applications.[7] New versions were announced in 2008 and 2012.[8][9]
The integrated Rule-Oriented Data management System (iRODS) is a follow-on project of the SDSC SRB team (which became the Data Intensive Cyber Environments group), and largely replaced the use of SRB. iRODS is based on SRB concepts but was completely re-written, includes a highly-configurable rule engine at its core and is fully open source. Conferences in 2011 included demonstrations of iRODS.[10]
