	SGI - Developer Central Open Source \| XFS
		XFS is a full 64-bit filesystem, and thus is capable of handling filesystems as large as a million terabytes.
		XFS also continues to evolve to match the capabilities of the hardware it is being deployed on.
		XFS was the first filesystem to implement delayed space allocation for buffered writes, supports direct I/O, provides an optional realtime allocator, and is able to align allocations based on the geometry of the underlying storage device.

	XFS - Wikipedia, the free encyclopedia
		XFS is the oldest journaling file system available for UNIX systems, and has a mature, stable and well-debugged codebase.
		XFS provides journaling for file system metadata, where file system updates are first written to a serial journal before the actual disk blocks are updated.
		XFS does not provide direct support for snapshots, as it expects the snapshot process to be implemented by the volume manager.

		XFS: Tutte le informazioni su XFS su Encyclopedia.it
		XFS è un file system di tipo journaled con indirizzamento a 64 bit sviluppato da SGI per il sistema operativo IRIX, recentemente portato per la piattaforma libera GNU Linux con una sua completa introduzione nel kernel Linux.
		XFS è un file system maturo e scalabile con un sistema di journaling che minimizza l'impatto di read/write massive: usa un'efficiente struttura a tabelle che permette una rapida ricerca e altrettanto rapida nuova allocazione di spazio.

		Thus, XFS was born, and was made available to the computing public with the release of IRIX 5.3 in 1994.
		The arrival of XFS for Linux is exciting, primarily because it provides the Linux community with a robust, refined, and very feature-rich filesystem that's capable of scaling to meet the toughest storage challenges.
		XFS consistently won all tests that involved manipulating large files, which should be expected since it has been designed and tuned over the years to do this very well.

	Scalability in the XFS File System
		XFS has been shipping to customers since December of 1994 in a version of IRIX 5.3, and we are continuing to improve its performance and add features in upcoming releases.
		XFS is designed to run well over large, striped disk arrays where the aggregate bandwidth of the underlying drives ranges in the tens to hundreds of megabytes per second.
		XFS is designed to perform well on both the desktop and the server, and it is this focus on scalability that distinguishes XFS from the rest of the file system crowd.

	SGI - Developer Central Open Source \| Linux XFS (Site not responding. Last check: 2007-10-26)
		XFS is a huge amount of kernel code which means that your kernel is probably to big to fit on a boot floppy together with a inital ramdisk and scsi drivers.
		XFS is using an extra ioctl to set the block size of the device, it is not implemented for this device.
		Since XFS does not write data out to disk immediately unless you tell it to with fsync or an O_SYNC open (the same is true of other filesystems), you are looking at an inode which was flushed out to disk, but for which the data was never flushed to disk.

	Interview With the People Behind JFS, ReiserFS & XFS - OSNews.com
		XFS is an excellent file system, and there is an important area where XFS is higher performance than we are.
		XFS is slower than reiserfs for the typical file size distributions on "typical" file systems, and I encourage you to examine our benchmarks, where you will see that they are faster for very large file writes, and slower for typical file sizes.
		XFS is going to go into Linux 2.5/2.6 (they make changes to the kernel that are considered 2.5 material, and thus are not in 2.4), and I just bet you that by 2.6 they will have improved their "typical" file size performance by the time 2.6 ships.

	[XFS] About Us
		Originally all of the founders of the XFS were members of a Bridge Commander clan known as the X-Clan Starships.
		Since the founding of the XFS, the clan was always intended for the members to hold power and to decide the fate of the clan.
		XFS wanted to ensure that the members would always be in control of their clan and that no matter what, the members would be able to have a say in clan operations.

	LWN: Patch: XFS filesystem support

		XFS considers quota + information as filesystem metadata and uses journaling to provide a + higher level guarantee of consistency.
		XFS quota can be used either + with or without the generic quota support enabled (CONFIG_QUOTA) - + they are completely independent subsystems.

	SGI - Developer Central Open Source \| XFS
		Barry Naujok has documented the XFS ondisk format which is a very useful reference.
		Since XFS does not write data out immediately unless you tell it to with fsync, an O_SYNC or O_DIRECT open (the same is true of other filesystems), you are looking at an inode which was flushed out, but whose data was not.
		For example, the tail of the log is moved when we are notified that a metadata write is completed to disk and we won't be able to guarantee that if the metadata is on a drive with the write cache enabled.

		However, in XFS these inodes are stored in B+Trees and actually are stored in two B+Trees, one for free inodes and the other for used inodes.
		XFS waits as long as possible to actually write data to the disc.
		The only "odd" thing about the XFS superblock is that because of where it is in the partition (right at the beginning), you cannot install a boot block to an XFS partition.

	xFS (Site not responding. Last check: 2007-10-26)
		We are currently designing a serverless file system called xFS which will attempt to provide low latency, high bandwidth access to file system data by distributing the functionality of the server among the clients.
		By reducing the amount of redundant caching among clients and allowing the memory of idle machines to be utilized, cooperative caching can lower the latency of reads by reducing number of requests which must go to disk.
		The function of locating data in xFS is distributed by having each client responsible for servicing requests on a subset of the files.

	XFS: It's worth the wait
		XFS is able to accomplish this fast recovery by logging all file transactions with information on free lists, inodes, directories, and so on.
		After a crash, the logs are analyzed, and XFS can quickly determine which transactions must be done in order to synchronize the file system to the state it was in prior to the crash.
		Because the Linux implementation of XFS is still in the development stages, the features listed may or may not be applicable to the Open XFS for Linux specification.

		XFS is a high-performance journaling file system created by SGI (formerly Silicon Graphics Inc.) for their IRIX UNIX implementation.
		In May 2000, SGI released XFS under an open source license.
		Like ReiserFS (but unlike Ext3), XFS uses a logical journal - it does not journal literal filesystem blocks, but instead logs metadata changes.

		It was nice from the perspective where you could have the modules installed for each kernel installed, but in the case where you just wanted the updated kernel to have the updated driver without having to do anything extra it was a pain.
		The XFS stuff has been moved to module form that can be used in both the standard kernel and the plus kernel.
		I'm not pissing and moaning about an un-supported kernel, but when Johnny 1st mentioned the availability of an un-supported but additional kernel option, he specifically said XFS support was enabled.

	Experience with a Distributed File System Implementation (Site not responding. Last check: 2007-10-26)
		Second, xFS implements a complex, multithreaded service that is tightly coupled with the underlying operating system.
		Furthermore, the xFS system tested the limits of abstractions such as threads, RPC, and vnodes that have traditionally been used in building distributed file systems.
		Based on our experience, we suggest several strategies that should be followed by those wishing to build distributed operating systems services, and we also indicate several areas where programming tools and operating system abstractions might be improved.

		Since these devices are often complex, difficult to manage and proprietary, the development of a standardized interface between them and both Windows-based applications and Windows operating systems can offer financial institutions and their solution providers immediate enhancements to productivity and flexibility.
