The AFF C30 and AFF C60 storage systems offer flexibility in expanding or replacing I/O modules to enhance network connectivity and performance. Adding, hot-swapping, or replacing an I/O module is essential when upgrading network capabilities or addressing a failed module.

You can replace a failed I/O module in your storage system with the same type of I/O module, or with a different type of I/O module. You can hot-swap a cluster and HA I/O module when your storage system meets specific requirements. You can also add an I/O module to a storage system with available slots.

  • Add an I/O module

    Adding additional I/O modules can improve redundancy, helping to ensure that the storage system remains operational even if one I/O module fails.

  • Hot-swap a cluster and HA I/O module

    Hot-swapping a failed cluster and HA I/O module can restore the storage system to its optimal operating state. Hot-swapping is done without having to manually take over the impaired controller.

    To use this procedure, your storage system must be running ONTAP 9.17.1 or later and meet specific system requirements.

  • Replace an I/O module

    Replacing a failing I/O module can restore the storage system to its optimal operating state.
