Infrastructure Simplification– Consolidate distributed, discrete servers and their networks– IBM mainframe qualities of service– Exploit built-in z/VM systems management
Speed to Market– Deploy servers, networks, and solutions fast– React quickly to challenges and opportunities– Allocate server capacity when needed
Technology Exploitation– Linux with z/VM offers more function than Linux alone– Linux exploits unique z/VM technology features– Build innovative on demand solutions
Why Run Linux on z/VM?
© 2009 IBM Corporation6
Do more with less– Consolidate more servers, more networks, more
applications, and more data with Linux on z/VM– Achieve nearly 100% utilization of system resources nearly
100% of the time – Enjoy the highest levels of resource sharing, I/O bandwidth,
and system availability
Reduce costs on a bigger scale– Consume less power and floor space– Save on software license fees– Minimize hardware needed for business continuance and
disaster recovery
Manage growth and complexity– Exploit extensive z/VM facilities for life cycle management:
provisioning, monitoring, workload mgmt, capacity planning, security, charge back, patching, backup, recovery, more...
– Add hardware resources to an already-running system without disruption – the epitome of Dynamic Infrastructure
– Consolidation on a scale up machine like System z means fewer cables, fewer components to impede growth
Smarter Virtualization with IBM System z
© 2009 IBM Corporation7
System z is thoroughly architected to host applications in a virtualized environment
This is accomplished with a coordinated set of investments that permeate the technology stack of hardware, firmware, hypervisors, and operating systems
This means clients can maximize the utilization, scalability, and security of all system assets, including:
– CPU– Memory– I/O– Networking– Cryptography
All with exceptional levels ofoperational ease and cost efficiencies
“But there’s another key factor that could impede the growth of x86 server virtualization. With the mainframe, most system components [come] from the same vendor (IBM). With x86 server virtualization, the microprocessor, server platform, storage, hypervisor and operating systems typically come from multiple vendors. ‘These vendors may have conflicting objectives,’ Burns writes.” – Charles Burns, author of “The Many Faces of Virtualization: Understanding a New IT Reality”, quoted in NetworkWorld.com*

A fundamental strength of z/VM is its ability to share system resources to an extreme level
System z virtual machines can share all hardware assets with very high levels of resource utilization– Both real and virtual (z/VM) resources can be shared with very high
levels of bandwidth and reliability for enhanced workload throughput Linux can exploit z/VM-unique facilities for even higher levels
of resource utilization and operational efficiencies– Increase staff productivity and reduce memory consumption by sharing
Linux program executables with z/VM DCSS technology– Improve memory utilization with Virtual Disks in Storage and
Cooperative Memory Management– Enhance virtual networking bandwidth and availability using Link
Aggregation and the z/VM Virtual Switch

Allocate system resources per guest image using SHARE command– This is a highly flexible and self-managed
function of the z/VM Control Program – Reserve CPU capacity for peak usage
• Use it when needed• Relinquish the processor cycles for
other servers when not needed– "Absolute guests" receive top priority– The Virtual Machine Resource Manager can
be used to monitor and adjust remainingcapacity allocated to "Relative guests“
– Also use VMRM to prioritize I/O operationsamong guest images via “I/O PriorityQueuing” z/VM Control Program

A fundamental strength of z/VM is its ability to overcommit system resources: “Do more with less”
Users can host an environment that consumes considerably more CPU and memory, in aggregate, than what is configured in the z/VM LPAR
– This can translate into cost savings for hardware and software– Consider a Linux-on-z/VM environment with a 25-to-1 overcommitment of
CPU capacity:

Allows z/VM guests to expand or contract the number of virtual processors it uses without affecting the overall CPU capacity it is allowed to consume
– Guests can dynamically optimize their multiprogramming capacity based on workload demand
– Starting and stopping virtual CPUs does not affect the total amount of CPU capacity the guest is authorized to use
– Linux CPU hotplug daemon starts and stops virtual CPUs based on Linux Load Average value
Helps enhance the overall efficiency of a Linux-on-z/VM environment
Note: Overall CPU capacity for a guest system can be dynamically adjusted using the SHARE setting

Extreme Linux-on-z/VM VirtualizationLinux Exploitation of z/VM DCSS Support
Linux Linux Linux Linux Linux
VirtualMemory
RealMemory
Discontiguous Saved Segments (DCSS)– Share a single, real memory location among
multiple virtual machines– Can reduce real memory utilization
Linux exploitation: shared program executables– Program executables are stored in an execute-in-
place file system, then loaded into a DCSS– DCSS memory locations can reside outside the
defined virtual machine configuration– Access to file system is at memory speeds;
executables are invoked directly out of the filesystem (no data movement required)
– Avoids duplication of virtual memory– Helps enhance overall system performance
and scalability z/VM V5.4 support enhancements:
– Segments can reside above 2 GB address line– Enables even greater system scalability– New addressing limit is 512 GB

VDISK support is Data-in-Memory technology– Simulate a disk device using real memory– Achieve memory speeds on disk I/O operations– VDISKs can be shared among virtual machines
Linux exploitation: high-speed swap device– Use VDISKs for Linux swap devices instead of
real disk volumes– Reduces demand on I/O subsystem– Helps reduce the performance penalty normally
associated with swapping operations– An excellent configuration tool that helps clients
minimize the memory footprint required for virtual Linux servers
– Helps improve the efficiency of sharing real resources among virtual machines

architecture (e.g., z/OS and Linux for System z)– Provides the potential benefit of PAVs for I/O issued to minidisks owned or shared by
guests that do not support native exploitation of PAVs, such as z/VSE, z/TPF, CMS, or GCS
IBM System Storage DASD volumes must be defined to z/VM as:– 3390 Model 2, 3, or 9 on a 3990 Model 3 or 6 Controller– Or…2105, 2107, or 1750 Storage Controller– Note: 3380 track-compatibility mode for the 3390 Model 2 or 3 is also supported.
Potential benefit:– Designed to improve I/O response times by reducing device queuing delays

z/VM HyperPAV Support
IBM System Storage DS8000 HyperPAV is designed to:– Provide more efficient Parallel Access Volumes (PAV) function – Help customers who implement larger volumes to scale I/O rates without the need
for additional PAV-alias definitions – Help reduce overhead, improve addressing efficiencies, and provide storage
capacity and performance improvements– Enable a dynamic response to changing workloads– Reduce costs via simplified management of aliases– Enable customers to stave off migration to larger volume sizes
z/VM support is designed to:– Potentially reduce the number of alias-device addresses needed for parallel I/O
operations– Provide support of HyperPAV volumes as linkable minidisks for guest operating
systems, such as z/OS, that exploit this new PAV architecture– Provide the potential benefits of HyperPAV volumes for minidisks owned or shared
by guests that do not specifically exploit HyperPAV volumes (e.g., CMS, Linux)
