Installing Stratus Cloud Availability Services

Installing Stratus Cloud Availability Services supplements the standard KVM hypervisor with Stratus availability extensions that allow you to deploy your mission-critical instances in fault-tolerant KVM (KVM-FT) pair groups. You can install Availability Services before or after installing Stratus Cloud Workload Services.

You may prefer to install Availability Services on your compute nodes when you configure your OpenStack environment to meet the requirements of the Stratus Cloud Solution, as described in other topics of the Stratus Cloud Solution Installation Guide.

To install Stratus Cloud Availability Services:

1. Prepare your OpenStack environment for the additional requirements of the KVM-FT hypervisor. See KVM-FT Hardware and Software Requirements.
2. Connect the Ethernet cables between the compute nodes that will run the KVM-FT hypervisor. See Connecting Ethernet Cables Between KVM-FT Compute Nodes.

3. If the network firewall at your site prevents you from accessing the Internet, set up local yum software repositories and prepare each compute node to work around this restriction for the installation process. See Preparing to Install the Stratus Cloud Solution Without Internet Access.

4. Install the Availability Services software on the compute nodes. See Installing Stratus Cloud Availability Services on KVM Compute Nodes.
5. Install the Quorum server service (QSS) on two dedicated servers in your OpenStack environment. See Installing Quorum Servers for Stratus Cloud Availability Services.
6. Set the KVM-FT hypervisor pair group(s) and create a test application. See Configuring the KVM-FT Hypervisor.
7. Before deploying any KVM-FT applications for production use, optionally configure your KVM-FT hypervisors and Ethernet switches to increase performance, as described in Improving the Performance of Stratus Cloud Availability Services.
