E.4.2 Summary - IBM z13s Technical Manual

E.4.2 Summary

DPM provides simplified z Systems hardware and virtual infrastructure management that
includes integrated dynamic I/O management for users who intend to run Linux on z Systems
and KVM for IBM z as hypervisor, running in a partition.
The new mode, DPM, provides partition lifecycle and dynamic I/O management capabilities
through the HMC to provide these capabilities:
Create and provision: Creation of new partitions, assignment of processors and memory,
configuration of I/O adapters (Network, FCP Storage, Crypto, and Accelerators).
Manage the environment: Modification of system resources without disrupting running
workloads.
Monitor and troubleshoot the environment: Source identification of system failures,
conditions, states, and events that might lead to workload degradation.
A CPC can be in either the DPM mode or standard PR/SM mode. The mode is enabled prior
to the CPC power-on reset (POR).
DPM mode requires two OSA-Express 1000BASE-T Ethernet features for primary and
backup connectivity (OSA-Express4S 1000BASE-T Ethernet #0408), along with associated
cabling (HW for DPM FC0016).
