Definition - What does Single-Image Mode mean?
In IT, the term "single-image mode" refers to a software setup where multiple processors are shown as one collective processor within an operating system environment. The separate resources are shown as a single image to give administrators a different view of the full system.
Techopedia explains Single-Image Mode
The idea of setting up multiple central processing units (CPUs) as a single-image view has something to do with the complexity of today's IT architectures. For example, in hardware virtualization, administrators may set up any number of processors or partition physical processors into virtual CPUs for use by individual virtual machines. In order to provide a clear and transparent operational information, a single-image mode can be used to demonstrate how processing gets done across an entire system.
