HPE Serviceguard for Linux (SGLX) is a High Availability and Disaster Recovery clustering software designed to protect applications / workloads from planned and unplanned downtimes. It ensures 24x7 application / workload availability by continuously monitoring the health of the infrastructure and other resources impacting their availability . Any event or failure affecting the application / workload availability, SGLX automatically moves the application and its associated resources to other servers (nodes) in the cluster. SGLX inbuilt monitors quickly responds to failures affecting the server, storage, network, SAN & LAN connectivity, data replication, processes, memory, disk, operating system, and its framework allows monitoring and responding to any custom event e.g. security vulnerabilities. SGLX also allows moving the applications within or across on-prem and cloud environments to perform system maintenance or upgrades.

The offering is available via "BYOL" and you can get a quote for licenses from HPE SGLX product page.

1. You need just one instance of SGMGR+ UI and Quorum Server across multiple clusters. If you do not have it already, select Centralized Serviceguard Management and Arbitration Instance from dropdown of SGLX Azure VM extension and create one. If you already have it then you can skip this step.
2. Provision Serviceguard Cluster Nodes for the workload of your choice by selecting the appropriate Serviceguard Add-on from dropdown of SGLX Azure VM Extension.
3. Install and configure the application on the systems provisioned in step 2. If desired application is already installed and configured on the selected nodes then you can skip this step.
4. From SGMGR+ Graphical User Interface (refer Step 1):
   1. Navigate to HA-DR Platform under Infrastructure menu option, and follow the on-screen instructions to create a HA-DR Platform (cluster) of the nodes provisioned in Step 2
      OR
   2. Navigate to Deploy under Workloads menu option, and follow the on-screen instructions to bring your workload in the purview of SGLX cluster on the nodes provisioned in Step 2
