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.

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

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.

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
