Carhartt's Implementation of Maxava HA for IBM i

This case study outlines how Carhartt utilizes Maxava HA to maintain business continuity for its IBM i operations. Carhartt operates a large IBM i environment across two IBM Power10 servers, supporting critical applications such as Warehouse Management and Commerce. The company traditionally employed a one-to-one high availability/disaster recovery (HA/DR) strategy but has adopted a flexible one-to-many configuration for its Commerce environment. This approach allows for efficient handling of business intelligence tasks and backups without disrupting production. The case study details a significant incident where a role swap was executed to address a critical issue with the Commerce database server. Carhartt's staff followed a detailed recovery runbook, which was developed through prior testing and collaboration with Maxava's technical team. The role swap was completed smoothly, minimizing disruption. The case study emphasizes the importance of simulated role swap tests in preparing for real-life scenarios and highlights the partnership between Carhartt and Maxava in ensuring reliable IT operations.
