Product Description
The HPE Q0D26A Red Hat High-Availability Add-On is a critical component for organizations that require maximum uptime and resilience for their mission-critical applications and services. This add-on extends the capabilities of Red Hat Enterprise Linux (RHEL) by providing robust clustering and failover mechanisms. It ensures that if a primary server or service fails, a secondary system can automatically take over, minimizing or eliminating service interruptions. The solution is built upon industry-standard open-source technologies, primarily Pacemaker and Corosync. Pacemaker is the cluster resource manager that controls and monitors the resources (like IP addresses, file systems, and applications), while Corosync provides the reliable messaging layer for cluster communication. Together, they create a highly available environment that can withstand hardware failures, software crashes, or planned maintenance without impacting end-users. This add-on is essential for workloads such as databases, web servers, and other business-critical applications where downtime can lead to significant financial losses or reputational damage. The subscription model ensures that customers receive ongoing support, updates, and access to the latest features and security patches from Red Hat, maintaining the integrity and performance of their high-availability infrastructure.
