• Compression: SD-UX supports compression functionality to reduce
the amount of data being transferred.
• Staging: SD-UX supports staging software to intermediate depots
either on the installation target or onto a source more accessible to
the target, which has been preconfigured to use the alternate source.
• Recovery: SD-UX supports automatic procedures to recover from
failed installations, leaving the system in the same state as previous.
There are also manual means through use of multiple versions.
• Multiple Versions: SD-UX supports installing multiple revisions of
the same software on a system at the same time, if the software
supports it. Then, the old version can be unconfigured, and the new
version configured as the active version. In case of any problems, the
old version can be restored as the active version by unconfiguring the
new version and reconfiguring the old.
Each of these topics is discussed in the following sections.
