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.

OpenStack and z/VM
Background about z/VM
 A 40 year history
 Supports Linux, as well as other IBM Operating Systems like z/OS, zVSE, zTPF.
 Part of a 2-layer approach to virtualization with logical partitioning
 Strengths: memory overcommitment, I/O, ability to run hundreds to thousands of guests on a
single hypervisor
 Examples of workloads that we run: web servers, databases
 Examples of customers: banks, insurance companies, government agencies

OpenStack and z/VM
Challenges for z/VM customers
 No native GUI interface for setting up/managing guests or applications, many customers
were writing their own
 Virtual machine sprawl
 Virtual configuration sprawl
 All system z shops have other platforms as well and they want solutions that manage across
the different platforms
 A standardized interface would make it easier to bring new applications to z

OpenStack and z/VM
Cloud and self-service
 System z customers tend to be worried about security and track their virtual machines very
closely for auditing purposes, even those used for development and test
 That process can be very time-consuming
 It also leads to extra virtual machines being left around, no one wants to give up a resource
if it takes a long time to get new machines
 Self-service for guest creation could save time/money, submit one request for a pool of
resources and let developers create what they need
 Of course this has to still have the security and auditing necessary
 System z customers are interested in the savings, but wary of the auditing and performance
implications of cloud

OpenStack and z/VM
Architecture
 Use our existing xCAT support to provide REST API interfaces
 Minimize specialty code in OpenStack, since we're not yet in the community
 Take advantage of system z features (more on this later)
 Build the support into z/VM itself, although the supported configuration is for use with the
IBM Cloud Manager family of products
 Also there was a corporate directive for all IBM hypervisors to support OpenStack. There
were a few reasons for this:
– Continuity and ease of use of different IBM products. We're trying to make our portfolio
more uniform.
– IBM is dedicated to the Open Source community. This means that our Cloud Manager
controller node can control several different architectures.

OpenStack and z/VM
Advantages of OpenStack on z/VM
 Ease of installation:
– Instead of buying lots of extra products that you have to configure, you only need to
know:
• Disk configuration
• An IP address for OpenStack
• An OSA card address for OpenStack
– Installation and configuration of SMAPI, xCAT, and OpenStack is done automatically
 Because we own and configure the whole stack, we can take advantage of data sharing, like
having nova and glance share images
 We can also use system z special features, like our super-fast copy (Flashcopy) for copying
an image to a volume.
 Because we're supporting OpenStack APIs, it means that new applications written to use
them will work on z, no porting required
