Planning your HA pair configuration
As you plan your HA pair, you must consider recommended best practices, the requirements, and the possible variations.
- Best practices for HA pairs
To help your HA pair to be robust and operational, you must be familiar with configuration best practices. - Setup requirements and restrictions for standard HA pairs
You must follow certain requirements and restrictions when setting up a new standard HA pair. These requirements help provide the data availability benefits of the HA pair design. - Setup requirements and restrictions for mirrored HA pairs
The restrictions and requirements for mirrored HA pairs include those for a standard HA pair with these additional requirements for disk pool assignments and cabling. - Requirements for hardware-assisted takeover
The hardware-assisted takeover feature is available on systems where the Service Processor module is configured for remote management. Remote management provides remote platform management capabilities, including remote access, monitoring, troubleshooting, logging, and alerting features. - If your cluster consists of a single HA pair
- Storage configuration variations for HA pairs
Because your storage management and performance requirements can vary, you can configure HA pairs symmetrically, asymmetrically, as an active/passive pair, or with shared disk shelf stacks. - HA pairs and storage system model types
