24 Chapter 2 Setting Up a Storage Area Network
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.
Note: If you do create your user accounts in a centralized directory, be aware that some
applications running on SAN client computers, such as Final Cut Pro, for example, work
better when users have local home directories. For help setting up local home
directories for users with network accounts, see “Creating Local Home Directories for
Network Accounts” on page 79.
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.
