Powervm; Powervm Editions; Logical Partitions - IBM Power 750 Technical Overview And Introduction

3.4 PowerVM

The PowerVM platform is the family of technologies, capabilities, and offerings that deliver
industry-leading virtualization on the IBM Power Systems. It is the umbrella branding term for
Power Systems virtualization (Logical Partitioning, Micro-Partitioning, POWER Hypervisor,
Virtual I/O Server, Live Partition Mobility, Workload Partitions, and more). As with Advanced
Power Virtualization in the past, PowerVM is a combination of hardware enablement and
value-added software. The licensed features of each of the three separate editions of
PowerVM are described in 3.4.1, "PowerVM editions" on page 122.

3.4.1 PowerVM editions

This section provides information about the virtualization capabilities of the PowerVM. The
three editions of PowerVM are suited for various purposes:
PowerVM Express Edition
This edition is designed for customers who want an introduction to more advanced
virtualization features at a highly affordable price, generally in single-server projects.
PowerVM Standard Edition
This edition provides advanced virtualization functions and is intended for production
deployments and server consolidation.
PowerVM Enterprise Edition
This edition is suitable for large server deployments such as multi-server deployments and
cloud infrastructures. It includes unique features like Active Memory Sharing and Live
Partition Mobility.
Table 3-3 lists the editions of PowerVM that are available on Power 750 and Power 760.

3.4.2 Logical partitions

Logical partitions (LPARs) and virtualization increase utilization of system resources and add
a new level of configuration possibilities. This section provides details and configuration
specifications about this topic.
Logical partitioning
Logical partitioning was introduced with the POWER4 processor-based product line and the
AIX Version 5.1, Red Hat Enterprise Linux 3.0 and SUSE Linux Enterprise Server 9.0
operating systems. This technology offered the capability to divide a pSeries system into
separate logical systems, allowing each LPAR to run an operating environment on dedicated
attached devices, such as processors, memory, and I/O components.
