Z13S Servers Highlights; Processor And Memory - IBM z13s Technical Manual

Open Systems Adapters (OSAs) across z/VM systems, z/VM 6.3 delivers enhanced
availability and reduced cost of ownership in network environments.
IBM z13s brings a new approach for Enterprise-grade Linux with offerings and capabilities for
availability, virtualization with z/VM, and a focus on open standards and architecture. The new
support of kernel-based virtual machine (KVM) on the mainframe provides a new modern,
virtualization platform to accelerate the introduction of Linux applications and new open
source-based technologies.
KVM: In addition to continued investment in z/VM, IBM has made available a KVM for
z Systems that can host Linux guest virtual machines. KVM for IBM z Systems can coexist
with z/VM virtualization environments, z/OS, IBM z/VSE®, and z/TPF. This modern,
open-source-based hypervisor enables enterprises to capitalize on virtualization
capabilities by using common Linux administration skills, while enjoying the robustness of
z Systems' scalability, performance, security, and resilience. KVM for IBM z Systems is
optimized for z Systems architecture and provides standard Linux and KVM interfaces for
operational control of the environment. In addition, it integrates with standard OpenStack
virtualization management tools, enabling enterprises to easily integrate Linux servers into
their existing traditional infrastructure and cloud offerings.
z13s servers continue to provide heterogeneous platform investment protection with the
updated IBM z BladeCenter Extension (zBX) Model 004 and IBM z Unified Resource
Manager (zManager). Enhancements to the zBX include the uncoupling of the zBX from the
server and installing a Support Element (SE) into the zBX. The zBX Model 002 and Model
003 can be upgraded to the zBX Model 004.

1.2.1 Processor and memory
IBM continues its technology leadership at a consumable entry point with the z13s servers.
z13s servers are built using the IBM modular multi-drawer design that supports 1 or 2 CPC
drawers per CPC. Each CPC drawer contains eight-core SCMs with either 6 or 7 cores
enabled for use. The SCMs host the redesigned complementary metal-oxide semiconductor
