	IBM Storage Tank— A heterogeneous scalable SAN file system
		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
		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.

	IBM Storage Tank—a heterogeneous scalable SAN file system IBM Systems Journal - Find Articles
		ST goes beyond cluster file systems, such as the IBM General Parallel File System (GPFS), (1) that allow a cluster of homogenous (single operating system) computers to share data by allowing thousands of heterogeneous computers, some subset of which may be clustered, to share data.
		SANs solve many problems for customers and simplify storage management, but their full potential remains untapped without a scalable, multiplatform, SAN file system such as ST.
		SANs enable the direct connection of large numbers of computers to large numbers of storage devices that range from simple disks to large, high-performance, high-function storage systems.

	InfoStor - File systems deliver on the promise of SANs
		Today's SAN file systems support a wide range of operating systems, which allows data in a single SAN pool to be shared among multiple operating systems.
		SAN file systems, on the other hand, allow heterogeneous servers to access each other's data and to use the same storage devices without allocation restrictions.
		SAN file systems have the potential to create opportunities to add data management features that can enhance the way that IT administrators use their storage resources.

	IBM unveils storage management system \| Tech News on ZDNet
		SAN refers to storage area networks, which connect storage devices and are often used by larger companies to hold data.
		SAN File System works by tying together servers in multiple locations over an Internet Protocol network and then allowing the distributed storage network to look and behave like a local file system, no matter where or on what operating system the data resides, according to IBM.
		SAN File System allows an organization to minimize copying, he suggested, by letting multiple servers access the same data.

	College of Business -- Computer Support -- File Storage
		Thus, faculty stored files on one server; student files were on other servers; and websites were on yet other servers.
		To provide better and more consistent service, the college recently purchased a file server cluster known as a SAN file system; that is, a storage area network file system.
		Files are backed up regularly in two ways: daily incremental back-up to disk and weekly full back-up to tape.

	SAN File Systems: Failure or Future? (Site not responding. Last check: 2007-10-24)
		SAN file systems are used mostly in applications where extremely large files are being shared and high data throughput (in the range of hundreds of megabytes per second) is needed.
		SAN file system technology is already relatively expensive, however, and use of Fibre Channel will up the ante by requiring expensive switches, host bus adapters and management software.
		SAN file systems will also be a logical fit for emerging object-based storage technologies, where applications are able to indicate to storage devices their performance and data-retention needs.

	IBM updates SAN File System software \| InfoWorld \| News \| 2004-05-25 \| By Robert McMillan, IDG News Service
		SAN file systems are useful for companies looking to provide a number of different servers with identical views of data on the network, said Arun Taneja, founder of storage industry research firm Taneja Group.
		The Ohio Supercomputer Center has been working since mid-January on implementing the SAN File System on 520T bytes of storage it is using for a variety of high-performance computing tasks.
		Though the center is using the SAN File System exclusively on IBM FAStT900 and FAStT600 storage servers right now, version 2.1 might change that, she said.

	SAN file system - Wikipedia, the free encyclopedia
		In enterprise storage, a SAN file system is a file system which has been optimized to be shared by multiple clustered servers over a storage area network.
		SAN file systems are like network attached storage (NAS) protocols (like SMB and NFS) in that they allow multiple computers to access the same file system (and even file) at the same time.
		Examples of File Systems include the Global File System, the SAN File System, and Oracle Cluster File System.

	Apple's SAN file system turns heads
		SAN file systems are a great idea, if you can afford one.
		They enable multiple users simultaneous access to the same file, but the price tag for this functionality, which includes sophisticated stuff like multi-platform data sharing, policy-based provisioning and file-level locking, is outrageously steep.
		The file system holds 16 TB of data and up to 64 clients can read and write to shared storage at the same time.

	IBM unveils SAN File System
		He said that SANs provide physical connectivity but not logical connectivity, which is a problem that needed to be solved at the file system level.
		Instead of installing a file system on each individual server connected to the SAN, SAN FS resides on a metadata server that runs out of band, meaning that data traveling among servers and storage does not travel through them.
		"[The SAN File System] provides a single file system interface that is easy to manage and install [applications] on, but allows administrators to select which files and directories are protected by remote copy," he said.

		05-03-2002 04:54 PM If you are using a clustered file system (two hosts mounting the same volumes on the SAN) then you can run multiple databases, on different hosts, from one set of binaries.
		If you are not using clustered file system then you will need to install the binaries on each host.
		Currently, our system is configured as Active/Passive so this means at one time only one node can access the database.

		Bruce Hillsberg, director of storage software strategy and technology at IBM, said the point of the SAN File System is to help companies with large data warehousing needs and customers deploying grid computing environments become more competitive by providing an easier way for administrators to manage the massive amounts of data that is stored.
		The traditional thorn in the side of administrators is that each file system is managed separately, making it difficult to set consistent user policies, or instructions on how the files can be accessed.

	Apple - Xsan
		Dozens of systems on the SAN can read and write to shared storage simultaneously, unlike other solutions which gate access at the volume level.
		Using Fibre Channel multipathing, in which two Fibre Channel cables connect a computer to the SAN, an Xsan client can theoretically achieve throughput of up to 400MBps, perfect for multiple editors working on a video project or a compute cluster that needs fast access to data to ensure each node crunches at full capacity.
		You may also use Xsan in a cross-platform environment alongside Windows-, UNIX- and Linux-based systems, using the ADIC StorNext File System, which is 100% interoperable with Xsan.
