18. World-Class Server Virtualization:
System z LPAR and z/VM
Helping clients reduce costs and improve control of their IT infrastructure
 Virtualization  Consolidation  Workload management  Automation
• Logical Partitioning (LPAR) and
z/VM are complementary
technologies
– Both employ great hardware and
firmware (PR/SM) innovations
developed over the years
– Virtualization is a part of the basic
componentry of the System z
platform
• LPAR
– Host a relatively small number
of very high-performance
virtual servers
– Very low overhead, hardware-based
virtualization through
partitioning
• z/VM
– Host large numbers of high-performance
virtual servers
– Low overhead, hardware-based,
true virtualization with extreme
levels of software augmentation
Together, System z LPAR and
z/VM technology provide:
– High performance “on the metal”
virtual servers for larger,
performance-critical workloads
– The ability to provision 1000s of
additional virtual servers flexibly
and on demand

The Linux’s all look the same (on different architectures)
and have the same Linux kernel source.
But they have different personalities, qualities,
features and options derived from the architectures.

Virtualization enables mixing of high and low priority workloads without penalty
Enterprise Linux Server
 Priority Workload
– No throughput reduction
– No response time increase
 Low Priority Workload
– Soaks up remaining processor minutes
