The SAN File System, also known as SFS, is distributed file system software created by DataPlow that enables high-speed, cluster file sharing among multiple, storage area network (SAN)-attached computers. DataPlow SFS is well suited for read/write-intensive applications where bandwidth and scalability are critical, such as webserving, digital media, data warehousing, scientific computing, broadcast, seismic processing, bioinformatics, CAD/CAM, datamining, medical imaging, and email serving.

Department of Defense SAN Study

The United States Department of Defense (DOD) commissioned a study of storage area network (SAN) technologies. This study compared DataPlow SFS, IBM/Tivoli SANergy, ADIC CentraVision File System (CVFS), and SGI CXFS file systems. After the study was completed, SGI opted not to publish CXFS performance numbers. This study, Functionality and Performance Evaluation of File Systems for Storage Area Networks (SAN) by Martha Bancroft, Nick Bear, Jim Finlayson, Robert Hill, Richard Isicoff, and Hoot Thompson, is published in the proceedings of the Eighth NASA Goddard Conference on Mass Storage Systems and Technologies [1].

IBM Storage Tank— A heterogeneous scalable SAN file system (10131 words)
	Fourth, it is not possible to move an application from a computer running one file system to another computer running a different file system without also reading all of the data of the application, modifying the data to the format of the second file system, and writing all the data back to disk.
	File meta-data, such as directory entries, and file attributes, such as last modification time, are presented to users and applications in a form that is compatible with the native file system interface of the platform.
	Although cluster file systems can probably be made to support heterogeneous server environments, it is much harder for them than it is for ST because the code to implement a cluster file system is larger and more complex than the code to implement an ST client.

EnterpriseStorageForum: SANs/NAS News (718 words)
	Crafting a SAN that shares an almost limitless amount of files irrespective of their make-up has been a challenge for storage vendors — until now, according to IBM.
	Hillsberg also said one of the reasons why a product like SAN File System is important is that many enterprises organize data in different ways and attach different significance to their data.
	The new IBM file system automatically sets policies and shuttles data to the appropriate server pools based on their degree of importance.
