Notes:
Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will
vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be
given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.
IBM hardware products are manufactured from new parts, or new and serviceable used parts. Regardless, our warranty terms apply.
All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual
environmental costs and performance characteristics will vary depending on individual customer configurations and conditions.

Extreme Virtualization with Linux on z/VM
Linux Exploitation of z/VM Discontiguous Saved Segments (DCSS)
DCSS support is Data-in-Memory
technology
– Share a single, real memory location among multiple
virtual machines
– Can reduce real memory utilization
DCSS DCSS DCSS
“B”
“B”
“B”
Linux exploitation: shared program
executables
– Program executables are stored in an execute-inplace file system, then loaded into a DCSS
– Execute-in-place (xip2) file system
– Access to file system is at memory speeds;
executables are invoked directly out of the file
system (no data movement required)
– Avoids duplication of virtual memory and data
stored on disks
– Helps enhance overall system performance
and scalability

z/VM Statements of Direction
Clustered Hypervisor Support and Guest Mobility
Clients can cluster up to four z/VM systems in a Single System Image (SSI)
Provides a set of shared resources for the z/VM systems and their hosted virtual machines
Users can run z/VM system images on the same and/or different System z10 servers
Simplifies systems management of a multi-z/VM environment
– Single user directory
– Cluster management from any system
• Apply maintenance to all systems in
the cluster from one location
• Issue commands from one system
to operate on another
– Built-in cross-system capabilities
– Resource coordination and protection:
network and disks
Dynamically move Linux guests from one z/VM
system to another with Live Guest Relocation
Cross-system communications for
“single system image” management
z/VM 1
z/VM 3
Shared disks
z/VM 2
z/VM 4
Cross-system external network
connectivity for guest systems
– Reduce planned outages; enhance workload management
– Non-disruptively move work to available system resources and non-disruptively move system
resources to work
Note: All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice, and represent goals and objectives only.

IBM Systems Director VMControl Image Manager
for Linux on System z Version 2.1
Announced July 21, 2009; Available July 24, 2009
VMControl Image Manager is a plug-in to IBM Systems Director V6.1
– Effectively replaces the “z/VM Center” extension of IBM Director V5.20
Provides support to manage and automate the deployment of virtual images from a
centralized location
– A virtual image consists of an operating system instance and the software stack, such as
middleware and applications, running on that operating system
VMControl Image Manager provides a graphical interface to create and deploy Linux images
on z/VM and AIX images on Power systems
– Definition of these system images is based on the industry-standard Open Virtualization
Format (OVF) specifications – facilitates importation of virtual images
– Deploy an all-in-one solution instead of OS, middleware, and application piece parts
– Clone already-tested system configurations
– Propagate virtual image updates to all instances
IBM Systems Director and VMControl Image Manager help
support a Dynamic Infrastructure
– Helps improve responsiveness to changing business needs
– May increase operational productivity
– Can help reduce service and support costs

KMD: Unix and Oracle Consolidation on System z
Source: Clabby Analytics, December 2008
When KMD, Denmark’s largest locally-owned information technology (IT) service
provider, ran out of capacity on its four, large Hewlett-Packard HP-UX/PA-RISCbased HP 9000 servers it decided to migrate its Perspektiv payroll/human
resource applications environment off of the HP-UX operating environment over
to Linux running on an IBM mainframe. By doing this, KMD was not only able to
greatly increase its application processing capacity but was also able to
demonstrate very significant cost savings over a five year period.
Use the end-of-life for HP
9000 and upcoming Itanium
technology refresh costs as
the catalyst for funding a
move to IBM.
Figure 1 KMD projected cost
savings moving from HP to an IBM
Mainframe
In this case - IBM has lower
investment costs and lower
ongoing running costs
