Step 3: Set Up Your Streaming Server
An administrator computer must be set up before you can configure and manage your
streaming server if, as in this example, the streaming server is running headless. For
information on setting up an administrator computer, see “Setting Up an Administrator
Computer” in Getting Started With Mac OS X Server (included on the Mac OS X Server CD).
Any computer with a reasonably up-to-date browser connected either directly to the local
network or to the Internet can be used to manage QTSS remotely once Mac OS X Server has
been configured. For this example, we assume that the broadcaster laptop in the streaming
setup illustration is also used for this purpose.
Although the Xserve comes with Mac OS X Server and QTSS preinstalled, the software must
be configured for the particular network to which it is being added and for the specific uses
to which it is to be put. For information on setting up Mac OS X Server, see Getting Started
With Mac OS X Server and Mac OS X Server Administrator’s Guide, included on the
Mac OS X Server CD.
Among the questions to be answered when setting up your streaming server are the
following:
Can the server computer be dedicated solely to streaming?
It’s best if your streaming server doesn’t also have to handle web serving, mail serving, and
other server tasks. This example setup includes a dedicated streaming server.
How much random access memory (RAM) is needed?
The minimum required to run QTSS is 128 megabytes (MB). Estimate about 256 MB of RAM
for every 50 MB of throughput you plan to serve. This setup assumes 256 MB of RAM.
How much hard disk storage is needed?
Video files can be large. A hinted one-hour presentation encoded at 300 Kbps (not optimized
for a server) will take up approximately 135 MB of hard disk space. A 60-GB hard disk can
store more than 400 such presentations.
Note: Here’s a formula for calculating streaming file sizes:
dataRateInBits / 8 bits * timeInSeconds = file size
