Configuring a Multi-Master cluster

You can implement high availability of real-time data by configuring IBM® Security Key Lifecycle Manager servers in a Multi-Master cluster.

Overview

All IBM Security Key Lifecycle Manager servers in the Multi-Master cluster are called master servers. Each server points to a single data source (primary database). The server that hosts the primary database is called the primary master server. The other master servers are called as standby master servers, and the databases on these servers are the standby databases.

You can configure a Multi-Master cluster by using the graphical user interface (GUI) or REST APIs. For more information, see Setting up a Multi-Master cluster.

Db2® high availability disaster recovery (HADR) is used as the underlying feature that ensures data redundancy. HADR configuration is managed internally by IBM Security Key Lifecycle Manager. Db2 HADR supports multiple standby databases in a Multi-Master setup.

Key features of a Multi-Master configuration

  • Keys that are created on a master server are accessible to other master servers in the cluster.
  • IPP devices and KMIP clients that are registered on a master server can access keys on another master server in the cluster.
