 Hard disk capacity and number of packages: Software Update packages can occupy
considerable hard disk space on server volumes, depending on the size and
configuration of the package and the number of packages being stored.
 Number of Ethernet ports on the switch: Distributing Macintosh clients over multiple
Ethernet ports on your switch offers a performance advantage. Each port must serve
a distinct segment.
 Number of Software Update servers on the network: You may want to provide different
software updates to various groups of users. By configuring Directory Services you
can offer different update services by network or hardware type, each targeting a
different Software Update server on the network.
Note: You can’t configure Software Update servers to talk to one another.
Setup Overview
Here is an overview of the basic steps for setting up Software Update service.
Step 1: Evaluate and update your network, servers, and client computers as
necessary
The number of client computers you can support using Software Update service is
determined by the number of servers you have, how they’re configured, hard disk
storage capacity, and other factors. See “Capacity Planning” on page 70.
Depending on the results of this evaluation, you may want to add servers or hard disks,
add Ethernet ports to your server, or make other changes to your servers.
Update all client computers to Mac OS X v10.4 or later in order for them to use the local
Software Update service.
Step 2: Create your software update service plan
Decide which users you want to access your software update service. You may have
groups of users to whom you want to provide unlimited access while offering others a
more limited choice of software updates. Such a plan would require more than one
software update server with client machines bound via directory services to managed
user preferences.
Step 3: Configure the Software Update Server
Decide whether you want to mirror and enable software updates from Apple
automatically or manage them manually. Set the maximum bandwidth you want a
single computer to use when downloading update packages from your server.
Step 4: Start the Software Update Service
Your server will automatically synchronize with the Apple Software Update server by
requesting a catalog of available updates. If you chose to automatically mirror updates,
your server will begin to download all available software update packages.
