Red Hat Network uses the RPM Package Manager (RPM) technology to determine what software additions and updates are applicable to each client system. Packages retrieved from Red Hat Network are usually in RPM format. Entire ISO images, however, are available through the Software tab of the Red Hat Network website, but are not available in RHN Satellite Server installations. If your Satellite has Solaris support enabled, you can use RHN Push to upload Solaris packages to custom channels used by Solaris clients.

RPM is a tool that provides users with a simple method for installing, uninstalling, upgrading, and verifying software packages. It also allows software developers to package the source code and compiled versions of a program for end users and developers.
