8.1 Overview
SD-UX install and copy throughput are dependent on the following factors:
• Speed of the network
• Size (i.e., number of bytes) of the product being transferred
• Number of files being transferred
• Number of targets any one source is serving simultaneously
SD-UX provides many features that can be used together to increase the speed and
success rates of distributed installations and copies. Many features are controlled by
options set in the system defaults file, separate options file, command line, or GUI. This
lets you set these features and options to best suit your own particular network and
software needs.
