Installing the System Software

Before you install the system software, you must perform some tasks to prepare for the installation. One of the tasks you will perform is to determine if Stratus preinstalled the system software (that is, Automated Uptime Layer with Smart Exchange and Windows Server) at the factory. This information determines which type of system software installation you perform:

• If Stratus preinstalled the system software at the factory, you perform a factory-installed system software installation.

• If Stratus did not preinstall the system software at the factory, you perform a full system software installation. This installation procedure installs Automated Uptime Layer with Smart Exchange and Windows Server, and allows you to enter customized configuration settings for your ztC Endurance system.

  Note: On all ztC Endurance systems, the Standby OS (Ubuntu, a Linux distribution) is preinstalled at the factory in an internal NVMe drive inside each compute module. In general, you need to access the Standby OS only for system software installation or troubleshooting purposes.

For both types of installations, you power on the system to boot the preinstalled Standby OS on both compute modules, and you later run configuration scripts to enter different settings that are required to support the software installation.

After the software installation completes, you need to perform some post-installation tasks, as described in Post-Installation Tasks.
