OS X Server

Product Overview

Xsan is a 64-bit cluster le system specically designed for small and large computing

environments that demand the highest level of data availability. This specialized

technology enables multiple Mac computers to share RAID storage volumes over

a high-speed Fibre Channel network. Each client can read and write directly to the

centralized le system, accelerating user productivity while improving workgroup

collaboration. Because everyone can work with the same les on the network, Xsan

dramatically improves the eciency of post-production and other data-intensive

workows.

The Xsan le system is built into OS X, allowing any Mac with appropriate connectivity

to access an Xsan volume. OS X Server includes the Xsan Admin application for hosting

and conguring Xsan volumes.

Volume Management

Xsan allows you to create storage pools made of identical sets of LUNs and stripe

them together for fastest-possible performance. Dierent pools oering special

storage characteristics can be combined into volumes; data placement settings, or

anities, enable you to direct data to specic volumes depending on performance

and protection requirements.

Metadata Controller Failover and File System Journaling

Xsan has a high-availability design that allows users to access mission-critical data

even in the event of a system or Fibre Channel network failure. Metadata controller

failover protects storage availability from server hardware failure. File system journaling

tracks modications to metadata, enabling quick recovery of the le system in case of

unexpected interruptions in service. And Fibre Channel multipathing allows le system

clients to automatically use an alternate data path should a failure occur.

Real-Time Monitoring, Graphs, and Event Notications

For day-to-day SAN management, OS X Server includes the Xsan Admin application.

Xsan Admin makes it easy to manage and monitor your SAN and to receive notications

about impending issues.
