	Xsan - Wikipedia, the free encyclopedia
		Xsan enables you to share one or more Xserve RAID devices with multiple Xserve or Macintosh systems.
		Xsan may be used in a cross-platform environment alongside Windows-, UNIX- and Linux-based systems using the StorNext File System, which is 100% interoperable with Xsan.
		Xsan 1.4 is available for Intel-based Macintosh computers as a Universal binary and supports file system access control lists.

	Apple - Xsan
		Xsan includes high-availability features to eliminate potential single points of failure, so you can use high-performance storage networking for enterprise consolidation and network-attached storage (NAS) replacement projects.
		Xsan Admin helps you get the most from your storage resources with user and group quotas, as well as affinities to associate files and folders with specific classes of storage.
		Xsan works with a number of third-party Fibre Channel switches, which are required to build a SAN.

	AFP548 - Xsan Introduction
		Apple has been heavily beta testing Xsan since mid-2004 at a number of different sites tweaking the StoreNext filesystem and the Xsan GUI for OS X. While Apple is very much targeting Xsan towards the video space, the enterprise data center can easily come along for the ride on this one.
		At the heart of it, this means that Xsan allows for multiple machines to directly access the same storage without the need for a fileserver in the middle.
		Also, Xsan can take advantage of Fibre Channel multipathing to allow for redudandent connections to redundant Fibre Channel switches so the failure of any Fibre Channel cable or switch will not result in an interruption of service as long as you have another FC connection to fall back on.

	Apple - Xsan - Video Workflow
		Xsan lets you work well within the bandwidth required per video stream for the most common editing formats.
		Xsan makes it easy for you to set storage policies and allocate different classes of storage to different purposes without forcing your editors to adhere to onerous rules.
		Xsan Admin will notify you via pager or email if a particular user, such as your capture/ingest or finishing station, nears its storage quota.

	AFP548 - Xsan Deployment Advice
		Xsan is a cluster file system for OS X. A SAN filesystem allows us to open up all our storage to all our devices.
		Xsan will control access to the files to make sure everyone is happy - and it does all this through metadata which is controlled, surprisingly enough, by what is called a metadata controller.
		Xsan supports 64 clients on the FC network (an XSR is not a client but a metadata controller is).

	MacDevCenter.com -- Xsan and You
		Xsan operates at speeds 20 times faster than typical network storage, since it uses 2 gigabit per second Fibre Channel protocol for its data transfer.
		Xsan uses a separate Ethernet network to pass these tokens, so that the Fibre Channel network is free to just pass the file data back and forth.
		If you glean one thing from this article, besides how cool Xsan is, it should be that you will need the guidance of someone who is not only an expert in the video realm, but someone who also knows a lot about Ethernet and Fibre Channel networking, OS X Server, and Unix in general.

	Apple Xsan Delaware Apple Administration for Xsan
		Apple Xsan Certification covers the knowledge necessary to configure and maintain all Apple software and hardware components necessary for an Xsan cluster file system.
		Xsan is Apple's 64-bit cluster file system which allows large amounts of hard disk storage to be utilized by multiple systems simultaneously and very high transfer speeds.
		Xsan is designed and suited for Video production, Data Center Storage, HPC (High-performance computing) and other situations requiring large amounts of disk space with high bandwidth needs.

	Apple ships Xsan, upgrades Xserve G5
		Xsan's applications extend beyond video and film, however; Apple sees a market for Xsan in business, government, education and high-performance computing -- all environments that can benefit from storage consolidation where features like metadata controller failover, Fibre Channel multipathing, file-level locking and more sophisticated volume management can be used effectively.
		The support plan covers Xsan setup and configuration, but users can also use the service to get answers to questions about setting up RAID, Fibre Channel cards, switches, Mac OS X Server and application software that will be used with the Xsan system.
		Xsan is interoperable with Advanced Digital Information Corp.'s StorNext File System, which means it can be used in mixed-platform environments that include the Windows, Unix and Linux operating systems, according to Apple.

	Apple's Xsan - The macosxhints Forums
		Xsan lets multiple computers concurrently access terabytes of storage on Xserve RAID over high-speed Fibre Channel.
		Xsan storage networking eliminates the bottlenecks of Ethernet-based network file servers, whose performance will only get worse over time as denser formats such as HD become more common.
		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.

		Not well known is the fact that the command's parameters change from one Xsan version to the next.
		The general rule with Xsan, since version 1.1 or so, is this: DNS isn't necessary, but if you have some you had better make sure it is perfect.

	Apple's Xsan Takes a Bite out of Storage Market
		As advertised, Xsan is ''The SAN File System for Mac OS X.'' It is Apple's OEM version of ADIC's StorNext File System, which is designed to be used in a SAN environment.
		One thing to note here, Xsan is not a ''SAN in a box'' solution that other vendors, such as HP or EMC, offer.
		So while it's not the ''perfect storage solution'', Xsan is, if used correctly, a solid entry into the midrange SAN field, and a compelling product for SMBs, especially those doing multimedia work, or for any company with a multimedia department.

	blog.noetech.com: Avid Unity and Apple's Xsan
		This means that on the Xsan you can have multiple pools per volume, and on Avids, multiple volumes per pool.
		On the Xsan, or most other SAN systems I would think, the smallest a volume can be is the size of one LUN.
		The Xsan is half to a third the cost of a comparable Unity system.

		Goguen said the Xsan, available in beta now and slated for autumn in production form, originally was built to meet demand from video professionals who found it impossible to work with high-definition video without a SAN.
		According to Apple, setup, administration and monitoring are built into Xsan's Admin tool, which provides volume management, SAN file system configuration and remote monitoring in an integrated interface.
		He added that he believes Xsan will follow the same path as other Apple products that were made for the company's core markets but spread to wider use over time.

	The visible SAN from Apple \| InfoWorld \| Column \| 2004-05-21 \| By Tom Yager (Site not responding. Last check: 2007-08-09)
		First, Xsan is really a SAN file system, which makes SANs useful and accessible beyond their core capabilities.
		But Xsan presents that storage in its most readily usable form, as disks that are partitioned into OS X HFS+ (HFS second-generation) volumes.
		Xsan is, by far, the most complex technology that Apple has produced.
