Dell System Update is an application designed to facilitate the application of updates on Dell EMC PowerEdge systems. DSU is a lightweight utility that provides an enhanced scripted update process for Dell EMC’s Linux customers. DSU includes an Inventory Collector that will inventory the target system, compare the results against a Repository or Catalog and only deploy the updates that are required. DSU also provides advanced scripting capabilities to customize the updates that are deployed. DSU can be pointed at the Dell Linux Repository for gathering the updates to deploy or at a custom catalog built with Dell Repository Manager for those customers that want to have a tightly controlled baseline of Firmware levels for their systems.
DSU introduced the ability to build a Bootable DSU that provides the advantages of the advanced scripting capability along with an innovative approach to gathering the updates for deployment. Bootable DSU can be built as a self-contained Bootable ISO that includes a Linux Kernel, DSU, Inventory Collector and the physical update files. But an innovative approach is also available that allows the creation of a Bootable DSU that points to a remote location for the update files. The advantage of this unique approach is that the Bootable DSU portion only needs to be built once, and when you want to change the updates to apply you just change the contents of the remote location.
The following are key advantages for Dell System Update:
Starting with DSU 1.4, support for Ubuntu operating systems is pre-enabled and the support is limited. All the DSU commands may function as usual without any issues. For more information on the catalog that has the updates for Ubuntu operating system, refer Ubuntu Catalog
