## Coupling Facility mode logical partition 

Parallel Sysplex is a synergy between hardware and software, which is a highly advanced technology for clustering that is designed to enable the aggregate capacity of multiple z/OS systems to be applied against common workloads. To use this technology, a special LIC is used, which is called CFCC. To activate the CFCC, a special logical partition must be defined. Only PUs that are characterized as CPs or Internal Coupling Facilities (ICFs) can be used for Coupling Facility (CF) partitions. For a production CF workload, it is recommended to use dedicated ICFs. 

## The z/VM-mode LPAR 

z14 servers support an LPAR mode, called z/VM-mode , that is exclusively for running z/VM as the first-level operating system. The z/VM-mode requires z/VM V6R4 or later, and allows z/VM to use a wider variety of specialty processors in a single LPAR, which increases flexibility and simplifying system management. 

For example, in a z/VM-mode LPAR, z/VM can manage Linux on IBM Z guests that are running on IFL processors while also managing z/VSE and z/OS guests on CPs. It also allows z/OS to fully use zIIPs. 

## Secure Service Container 

Secure Service Container (SSC) is an integrated IBM Z appliance and was designed to host most sensitive client workloads and applications, acting as a highly protected and secured digital vault, enforcing security by encrypting the whole stack: memory, network and data (in-flight and at-rest). An application that is running inside SSC (software appliance) is isolated and protected from outsider and insider threats.
