Configuring the Array Name
The Array Name page is used to define Vault arrays, Streamer arrays, or ISV arrays. For more
information about arrays, see the “Content Delivery System Architecture” section on page 1-10.
Note Currently the CDSM allows only for the creation of one Vault array.
To view the current Array Name listings, choose Configure > System Level > Array Name. The array
names currently configured are listed.
To configure an array name setting, do the following:
Step 1 Choose Configure > System Level > Array Name. The Array Name page is displayed.
Step 2 Enter the array name used to identify the group of servers.
To reset the field, click Reset.
Step 3 Click Submit.
Configuring QAM Gateways
The QAM Gateway page is used to define associations between the Streamers and QAM gateways and
to define the QAM gateway type when using the Asynchronous Serial Interface (ASI) streaming mode.
Note The QAM Gateway page is not available if the Stream Destination is set to IPTV. For more information,
see the “Stream Destination” section on page F-4.
A QAM gateway is a device that sits between a Streamer and a QAM modulator. Depending on the
streaming mode and design of your network, a QAM gateway is a Layer 3 routing device, gigabit
Quadrature Amplitude Modulation (GQAM), Harmonic Narrowcast Services Gateway (NSG), Path1, or
a similar device. If you are using gigabit Ethernet as the streaming mode, the QAM gateway and the
QAM modulator are the same device—a GQAM.
Stream Steering
Stream steering determines which Streamers serve streams to a QAM device. There are two types of
stream steering:
• Single site
• Multi-site
Single-site steering uses only one Stream Group to serve streams to a QAM device. Multi-site steering
can use more than one Stream Group to serve streams to a QAM device.
