Chapter 2 Setting Up a Storage Area Network 37
IP Addresses and Domain Names
Assign fixed, non-routed IP addresses to all clients, controllers, and storage devices
connected to the SAN Ethernet network. Don’t use DHCP to assign addresses to SAN
devices. You can use the following ranges of IP addresses on 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 service, 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.
