1. Introduction The GridFTP User's Guide provides general end user-oriented information. 2. Usage scenarios 2.1. Basic procedure for using GridFTP (globus-url-copy) If you just want the "rules of thumb" on getting started (without all the details), the following options using globus-url-copy will normally give acceptable performance:
globus-url-copy -vb -tcp-bs 2097152 -p 4 source_url destination_url
The source/destination URLs will normally be one of the following: 2.1.1. Putting files One of the most basic tasks in GridFTP is to "put" files, i.e., moving a file from your file system to the server. So for example, if you want to move the file /tmp/foo from a file system accessible to the host on which you are running your client to a file name /tmp/bar on a host named remote.machine.my.edu running a GridFTP server, you would use this command:
globus-url-copy -vb -tcp-bs 2097152 -p 4 file:///tmp/foo gsiftp://remote.machine.my.edu/tmp/bar
[Note] Note
In theory, remote.machine.my.edu could be the same host as the one on which you are running your client, but that is normally only done in testing situations.
2.1.2. Getting files A get, i.e, moving a file from a server to your file system, would just reverse the source and destination URLs:
[Tip] Tip
Remember file: always refers to your file system.
globus-url-copy -vb -tcp-bs 2097152 -p 4 gsiftp://remote.machine.my.edu/tmp/bar file:///tmp/foo
2.1.3. Third party transfers Finally, if you want to move a file between two GridFTP servers (a third party transfer ), both URLs would use gsiftp: as the protocol:
globus-url-copy -vb -tcp-bs 2097152 -p 4 gsiftp://other.machine.my.edu/tmp/foo gsiftp://remote.machine.my.edu/tmp/bar
2.1.4. For more information If you want more information and details on URLs and the command line options , the Key Concepts Guide gives basic definitions and an overview of the GridFTP protocol as well as our implementation of it. 2.2. Accessing data in... 2.2.1. Accessing data in a non-POSIX file data source that has a POSIX interface If you want to access data in a non-POSIX file data source that has a POSIX interface, the standard server will do just fine. Just make sure it is really POSIX-like (out of order writes, contiguous byte writes, etc). 2.2.2. Accessing data in HPSS The following information is helpful if you want to use GridFTP to access data in HPSS. Architecturally, the Globus GridFTP server can be divided into 3 modules: In the GT4.0.x implementation, the data transform module and the DSI have been merged, although we plan to have separate, chainable, data transform modules in the future.
[Note] Note
This architecture does NOT apply to the WU-FTPD implementation (GT3.2.1 and lower).
2.2.2.1. GridFTP Protocol Module
The GridFTP protocol module is the module that reads and writes to the network and implements the GridFTP protocol. This module should not need to be modified since to do so would make the server non-protocol compliant, and unable to communicate with other servers.
2.2.2.2. Data Transform Functionality
The data transform functionality is invoked by using the ERET (extended retrieve) and ESTO (extended store) commands. It is seldom used and bears careful consideration before it is implemented, but in the right circumstances can be very useful. In theory, any computation could be invoked this way, but it was primarily intended for cases where some simple pre-processing (such as a partial get or sub-sampling) can greatly reduce the network load. The disadvantage to this is that you remove any real option for planning, brokering, etc., and any significant computation could adversely affect the data transfer performance. Note that the client must also support the ESTO/ERET functionality as well.
2.2.2.3. Data Storage Interface (DSI) / Data Transform module
The Data Storage Interface (DSI) / Data Transform module knows how to read and write to the "local" storage system and can optionally transform the data. We put local in quotes because in a complicated storage system, the storage may not be directly attached, but for performance reasons, it should be relatively close (for instance on the same LAN). The interface consists of functions to be implemented such as send (get), receive (put), command (simple commands that simply succeed or fail like mkdir), etc.. Once these functions have been implemented for a specific storage system, a client should not need to know or care what is actually providing the data. The server can either be configured specifically with a specific DSI, i.e., it knows how to interact with a single class of storage system, or one particularly useful function for the ESTO/ERET functionality mentioned above is to load and configure a DSI on the fly.
2.2.2.4. HPSS info
Last Update: August 2005 Working with Los Alamos National Laboratory and the High Performance Storage System (HPSS) collaboration ( http://www.hpss-collaboration.org ), we have written a Data Storage Interface (DSI) for read/write access to HPSS. This DSI would allow an existing application that uses a GridFTP compliant client to utilize an HPSS data resources. This DSI is currently in testing. Due to changes in the HPSS security mechanisms, it requires HPSS 6.2 or later, which is due to be released in Q4 2005. Distribution for the DSI has not been worked out yet, but it will *probably* be available from both Globus and the HPSS collaboration. While this code will be open source, it requires underlying HPSS libraries which are NOT open source (proprietary).
[Note] Note
This is a purely server side change, the client does not know what DSI is running, so only a site that is already running HPSS and wants to allow GridFTP access needs to worry about access to these proprietary libraries.
2.2.3. Accessing data in SRB The following information is helpful if you want to use GridFTP to access data in SRB. Architecturally, the Globus GridFTP server can be divided into 3 modules: In the GT4.0.x implementation, the data transform module and the DSI have been merged, although we plan to have separate, chainable, data transform modules in the future.
[Note] Note
This architecture does NOT apply to the WU-FTPD implementation (GT3.2.1 and lower).
2.2.3.1. GridFTP Protocol Module
The GridFTP protocol module is the module that reads and writes to the network and implements the GridFTP protocol. This module should not need to be modified since to do so would make the server non-protocol compliant, and unable to communicate with other servers.
2.2.3.2. Data Transform Functionality

The disadvantage to this is that you remove any real option for planning, brokering, etc., and any significant computation could adversely affect the data transfer performance. Note that the client must also support the ESTO/ERET functionality as well.
2.2.3.3. Data Storage Interface (DSI) / Data Transform module

2.2.3.4. SRB info
Last Update: August 2005 Working with the SRB team at the San Diego Supercomputing Center, we have written a Data Storage Interface (DSI) for read/write access to data in the Storage Resource Broker (SRB) (http://www.npaci.edu/DICE/SRB). This DSI will enable GridFTP compliant clients to read and write data to an SRB server, similar in functionality to the sput/sget commands. This DSI is currently in testing and is not yet publicly available, but will be available from both the SRB web site (here) and the Globus web site (here). It will also be included in the next stable release of the toolkit. We are working on performance tests, but early results indicate that for wide area network (WAN) transfers, the performance is comparable. When might you want to use this functionality: 2.2.4. Accessing data in some other non-POSIX data source The following information is helpful If you want to use GridFTP to access data in a non-POSIX data source. Architecturally, the Globus GridFTP server can be divided into 3 modules: In the GT4.0.x implementation, the data transform module and the DSI have been merged, although we plan to have separate, chainable, data transform modules in the future.
[Note] Note

2.2.4.1. GridFTP Protocol Module
The GridFTP protocol module is the module that reads and writes to the network and implements the GridFTP protocol. This module should not need to be modified since to do so would make the server non-protocol compliant, and unable to communicate with other servers.
2.2.4.2. Data Transform Functionality

[Nov 08, 2018] GT 6.0 GridFTP

Notable quotes:
"... GridFTP is a high-performance, secure, reliable data transfer protocol optimized for high-bandwidth wide-area networks ..."
Nov 08, 2018 | toolkit.globus.org

The open source Globus® Toolkit is a fundamental enabling technology for the "Grid," letting people share computing power, databases, and other tools securely online across corporate, institutional, and geographic boundaries without sacrificing local autonomy. The toolkit includes software services and libraries for resource monitoring, discovery, and management, plus security and file management. In addition to being a central part of science and engineering projects that total nearly a half-billion dollars internationally, the Globus Toolkit is a substrate on which leading IT companies are building significant commercial Grid products.

The toolkit includes software for security, information infrastructure, resource management, data management, communication, fault detection, and portability. It is packaged as a set of components that can be used either independently or together to develop applications. Every organization has unique modes of operation, and collaboration between multiple organizations is hindered by incompatibility of resources such as data archives, computers, and networks. The Globus Toolkit was conceived to remove obstacles that prevent seamless collaboration. Its core services, interfaces and protocols allow users to access remote resources as if they were located within their own machine room while simultaneously preserving local control over who can use resources and when.

The Globus Toolkit has grown through an open-source strategy similar to the Linux operating system's, and distinct from proprietary attempts at resource-sharing software. This encourages broader, more rapid adoption and leads to greater technical innovation, as the open-source community provides continual enhancements to the product.

Essential background is contained in the papers " Anatomy of the Grid " by Foster, Kesselman and Tuecke and " Physiology of the Grid " by Foster, Kesselman, Nick and Tuecke.

Acclaim for the Globus Toolkit

From version 1.0 in 1998 to the 2.0 release in 2002 and now the latest 4.0 version based on new open-standard Grid services, the Globus Toolkit has evolved rapidly into what The New York Times called "the de facto standard" for Grid computing. In 2002 the project earned a prestigious R&D 100 award, given by R&D Magazine in a ceremony where the Globus Toolkit was named "Most Promising New Technology" among the year's top 100 innovations. Other honors include project leaders Ian Foster of Argonne National Laboratory and the University of Chicago, Carl Kesselman of the University of Southern California's Information Sciences Institute (ISI), and Steve Tuecke of Argonne being named among 2003's top ten innovators by InfoWorld magazine, and a similar honor from MIT Technology Review, which named Globus Toolkit-based Grid computing one of "Ten Technologies That Will Change the World." The Globus Toolkit also GridFTP is a high-performance, secure, reliable data transfer protocol optimized for high-bandwidth wide-area networks . The GridFTP protocol is based on FTP, the highly-popular Internet file transfer protocol. We have selected a set of protocol features and extensions defined already in IETF RFCs and added a few additional features to meet requirements from current data grid projects.
