Disk Imaging Option - Symantec ALTIRIS DEPLOYMENT SOLUTION 6.9 SP4 - V1.0 Manual

Disk Imaging Option

Altiris® Deployment Server® Configuration Utility
The Disk Imaging tab lets you specify the number of client computers for image
multicasting and the maximum bandwidth to use during disk image multicasting.
Note
When multicasting a disk image using the PXE Server, the boot disk on the PXE Server
cannot be configured with an Intel Universal NIC driver (also known as an UNDI driver).
The multicasting feature is disabled for multicasting because of continued data
corruption problems inherent with the Intel Universal NIC driver. This unreliability
results in random files being corrupted in the image file, a problem that may appear
immediately or go undetected until you access the files later. As a result, if the
computers being imaged are booting to PXE boot files configured with an Intel universal
driver, multicasting is disabled and all computers are imaged using direct connections.

Mbps
To set when multicasting is used
1. Open the Altiris Deployment Server Configuration Utility from the Control
Panel of the Deployment Server computer.
2. Click Options and click the Disk Imaging tab.
3. Select one of the following, depending on when you want to use multicasting:
If you do not want to use multicasting, select the Use disk image multicast
threshold of n clients check box and set n to 0.
If you want to use multicasting whenever there is more than one client
computer, do NOT select the Use disk image multicast threshold of n
clients check box.
If you want to use multicasting only when there are more than a specific
number of client computers, select the Use disk image multicast threshold
of n clients check box and set n to the number of client computers.
Deployment Server Configuration Utility
Description
Specifies the number of client computers that must be
involved in a job before image multicasting is used. If the
number of client computers is less than or equal to the
number specified, multicasting is not used. Set this value to
0 to disable multicasting. If this option is not selected,
multicasting is used whenever there are two or more client
computers. When multicasting is not used, all client
computers become master computers and read from the
image server independently. You can use this option if your
client computers can read an image file from the server
faster than trying to coordinate master computers and
client computers.
Limits the bandwidth used in a multicasting session to a
user-defined number of Mbps. This option prevents the
multicasting operation from using all available bandwidth on
a network, so other network traffic can take place at a
reasonable rate.
