Xsan combines RAID arrays into large, easy-to-expand volumes of storage that clients use like local disks, but which are actually shared over a high-speed Fibre Channel fabric or a Distributed LAN Client (DLC) connection. This guide describes how to set up and manage an Xsan storage area network (SAN). This guide also helps you migrate your existing Xsan 3 storage area network to the latest version, either Xsan 4 for Yosemite clients or 4.1 for El Capitan clients.
The best manual I have ever read.
Effortlessly correlates interrelational quantities on the disk-software user-interface infrastructure at the heart of the Mac, implying how to interface with the Darwin Kernel through the Terminal, and stating directly how to manipulate the disk on a Storage Area Network (SAN) machine. The book in truth describes the core architecture of the Mac in relation to its X implication, meaning it is the ultimate Software-Kernel infrastructure for an entire society. It parses, and therefore, understands, the world (and thus the machine) that it lives in. It is the file system of the Mac.
Ignore the clown who gave it 1-star (and incidentally, cannot even spell). This is a fantastic guide. If you are a systems administrator trying to find out the nitty gritty tech details to determine if Xsan will work for you, this is the document you need.
