Product Overview

OS X Server

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 tech-

nology enables multiple Macs 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 be working 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 the fastest-possible performance. Dierent pools oering special

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

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

and protection requirements.

Metadata Controller Failover

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.

Journaling

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cation

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 noties you of

impending issues.
