![]() "Although this configuration can already be accomplished with the basic Mac OS X Server and appropriate hardware, Xsan provides better control over file locking, and almost completely eliminates the chance of file contention. faces: NAS (network attached storage) simply uses your existing network to access storage (usually as a file server). Xsan is a complete SAN solution that includes the metadata controller software, the file system client software, and integrated setup, management and monitoring tools. ![]() With the Xsan file system installed, these computers can read and write to the same storage volume at the same time. Xsan enables multiple Mac desktop and Xserve systems to access shared block storage over a Fibre Channel network. EonStor DS is a fast and reliable SAN storage with superior performance for media editors collaborating on macOS, Microsoft Windows, and Linux via high-speed Fiber channel or Ethernet network. Xsan is Apple Inc.'s storage area network or clustered file system for macOS. An alternative configuration uses servers to present volumes in a NAS configuration. Infortrend enhanced performance of its SAN storage EonStor DS that is ideally suited for building Apple Xsan SAN/StorNext. Apple's documentation assumes Xsan will be used in what some would call a "pure" SAN, where as many as 64 clients and control-lers can connect directly to the FC fabric. "In an Xsan environment, user files - up to 16TB - are transported over a FC (Fibre Channel) network, while file system meta-data and management information use a private Ethernet IP connection. At $999 per computer, Apple brings SAN technology within the reach of small and midsize enterprises. Xsan has also been designed for storage consolidation in business, government, education and high performance computing.Xsan is a 64-bit cluster file system. "The result is an inexpensive way to support Macintosh clients on an existing StorNext SAN, to create an Xserve-based SAN for Linux, Unix, and Windows systems, or a combination. Xsan is far and away the leading candidate for storage product of the year, because it takes an accepted SAN file system - in this case, ADIC's StorNext - and adds excellent integration with the Mac OS X operating system. For example, Apples Xserve RAID system provides no multipathing protection against the storage device, and if the storage port or controller fails, all the. As one would expect, the interface is pretty, but don't let the GUI lull you into Candyland. But Xsan beats all comers in the game Apple knows. ![]() "The first thing on my New Year's list is Apple's Xsan storage networking software. In particular, lifecycle management is left to ADIC's own StorNext Storage Manager or similar products. Apple Computer fixed a vulnerability in its Xsan storage area network software that could enable attackers to execute malicious code on computers connected. While the buzz whirls around product news coming out of Macworld Conference & Expo in San Francisco this week, here is a preview of Apple's just-released Xsan storage software, by InfoWorld Senior Analyst P.J.
