Full system partition

A special partition called the Full System Partition assigns all of your managed system's resources to one large partition.

The Full System Partition is similar to the traditional, non-partitioned method of operating a system. Because all resources are assigned to this partition, you cannot start any other partitions when the Full System Partition is running. You also cannot start the Full System Partition when other partitions are running. You should choose to use either the Full System Partition or create other partitions. Your I/O usage might be affected if you switch between these two options frequently.
