8  IBM z15 (8561) Technical Guide Coupling Facility mode logical partition The z/VM-mode LPAR Secure Service Container 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. 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 (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. IBM Z servers also offer other virtual appliance-based solutions and support other the  following hypervisors and containerization: The following LPAR modes are available for DPM: 6 IBM HSBN is a cloud service plan that is available on IBM Bluemixfi for Blockchain. 7 For more information, see the Running Docker Containers on IBM Z topic of IBM Knowledge Center. – IBM z/VMfi – IBM z/VSEfi –z / T P F – Linux on IBM Z GLYPH<SM590000> Coupling Facility: Coupling Facility Control Code (CFCC) GLYPH<SM590000> Linux only: – Linux on IBM Z GLYPH<SM590000> z/VM –z / V M GLYPH<SM590000> Secure Service Container: – VNA (z/VSE Network Appliance) – IBM High Security Business Network (HSBN) 6 GLYPH<SM590000> z/VM  GLYPH<SM590000> Linux on IBM Z (also used for KVM deployments) GLYPH<SM590000> Secure Service Container GLYPH<SM590000> IBM GDPS Virtual Appliance GLYPH<SM590000> KVM for IBM Z GLYPH<SM590000> Docker Enterprise Edition for Linux on IBM Systems 7
