Getting started with z/VM®

The IBM® Cloud Infrastructure Center is an advanced infrastructure management offering, including on-premises cloud deployments of IBM z/VM-based and KVM based Linux virtual machines on the IBM Z® and IBM® LinuxONE platforms.

This quick guide is to help to navigate through the IBM Cloud Infrastructure Center documentation for z/VM. Some sections also include content for KVM, skip these sections. Read this guide and keep the order of the topics to have a successful installation.

1. Architecture of z/VM

To understand the architecture of z/VM, read the overview page of the IBM Cloud Infrastructure Center, first. Here, you find an explanation and an architecture overview for z/VM: Architecture overview of z/VM

It is suggested to read the following sections first:

2. Prerequisites of z/VM® hypervisor

z/VM® needs to be installed and it is out of scope of the IBM Cloud Infrastructure Center. After z/VM is ready, there are some configurations and resources that need to be prepared before start the installation of the IBM Cloud Infrastructure Center.

The following prerequisites can be found in the link beneath:

If single system image(SSI) is required, the following prerequisites are needed:

(Optional and Reference only) z/VM setup and configuration:

After this step, the IBM Cloud Infrastructure Center architecture looks like in figure 1, means z/VM is ready.

3. Setup of management node and compute node(s)

With previous step done, next step is to install Linux operating system of IBM Cloud Infrastructure Center management node and compute nodes.

The requirement of management node and compute nodes can be found in the link beneath:

For compute nodes, additional configurations are needed:

To setup the management node and the compute node, follow these steps.

Now, the IBM Cloud Infrastructure Center architecture looks like in figure 2. The management node and compute nodes are ready to install the IBM Cloud Infrastructure Center on.

4. Installation

Now, all is ready to for the installation. Refer to following to do the installation of the IBM Cloud Infrastructure Center and add compute nodes to the installed IBM Cloud Infrastructure Center:

Run the environment checker to ensure the IBM Cloud Infrastructure Center is running well after the installation and add compute nodes.

For upgrade and uninstall:

After the installation, the management node and the compute nodes of the IBM Cloud Infrastructure Center are ready to manage the infrastructures, as shown in figure 3.

5. Day2 operations

After the installation of the IBM Cloud Infrastructure Center is complete, the following steps are required to enable the IBM Cloud Infrastructure Center to perform day2 operations such as virtual machine life cycle management, network management, storage management and so on.

Images:

Networks:

With network created and image uploaded to IBM Cloud Infrastructure Center, the architecture looks like figure 4:

6. Persistent storage

This step is optional and depends on the use case of the IBM Cloud Infrastructure Center. If a Fibre Channel Protocol(FCP) is planned, continue with this section.
