Overview

The Deploying Resilient AIX workloads on Power Virtual Server pattern deploys a multi-region solution on Power® Virtual Server that includes backup, high availability, and disaster recovery. This pattern can be used to provide an all-in approach for deploying a resilient power architecture within the Power® Virtual Server for AIX workloads.

The solution does not address application or database level high available design.

  • It can support up to 99.99% infrastructure availability when deployed as a multi-region.

  • It can support local high availability to protect from immediate LPAR failure.

  • It can support backups for AIX workloads to protect against data loss and can support disaster recovery scenarios.

  • It can support out-of-region disaster recovery.

The Power® Virtual Server resiliency pattern is intended to:

  • Accelerate and simplify solution design by providing a standard IBM Cloud deployment architecture reference following the IBM Architecture Design Framework.

  • Provide a prescriptive, end-to-end enterprise-class solution design, with diagrams, component architecture decisions along with rationale for cloud component selection for a resilient architecture.

  • Ensure that requirements can be met from a performance, system availability, and security perspective.

Pattern Considerations

  • Backup AIX data using a managed backup service.

  • Provide OS level local high availability between two AIX LPARs.

  • Provide a disaster recovery solution using SAN to SAN replication between two regions.

Always validate offerings are available in the regions you are deploying by using the IBM Cloud portal.

Resiliency needs to be considered for both the infrastructure and application levels. This pattern doesn't address application or database level high availability design. Consider latency between environments before deciding on a replication method. Consider options for synchronous and asynchronous replication when designing database replication to meet the requirements.
