20 Chapter 2 Setting Up a Storage Area Network
IP Addresses and Domain Names
For best results, assign fixed, non-routed IP addresses to all clients, controllers, and
storage devices connected to the SAN Ethernet network. You can use the following
ranges of IP addresses in your private (non-routed) subnet:
Directory Services
If you plan to use user and group privileges to control access to files and folders on the
SAN, you can simplify management by setting up or joining a user and group directory.
Although not required, a central directory lets you manage users and groups on one
computer instead of having to visit all SAN clients and controllers.
If you already have a directory, you can use the Directory Access application on each
controller and client to access the directory for user and group information.
If you don’t use a central directory service, you need to set up users and groups on
each SAN computer.
Important: If you create users and groups on each SAN computer, be sure that 1) each
user or group has a numeric user ID (UID) or group ID (GID) that is unique throughout
the SAN and 2) each user or group defined on more than one computer has the same
UID or GID on each computer.
If you don’t have access to a directory, you can use the directory services in Mac OS X
Server to set up an LDAP directory of SAN users and groups.
Outgoing Mail Service
Xsan can send SAN status notifications via email on your local subnet or corporate
network without using a separate mail server. However, to send notifications outside
your local network, you need an SMTP server to act as a mail gateway. If you don’t have
access to an outgoing mail server, you can use the mail service in Mac OS X Server to
set one up.
