The AFF A20, AFF A30, and AFF A50 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.

  • Add an I/O module

    You can add I/O modules to improve redundancy, helping to ensure that the storage system remains operational even if one I/O module fails. You can add I/O modules when there are slots available or when all slots are fully populated.

  • Hot-swap an I/O module

    You can hot-swap certain I/O modules for an equivalent I/O module to restore the storage system to its optimal operating state. Hot-swapping is done without having to perform a manual takeover.

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

  • Replace an I/O module

    You can replace a failed I/O module to restore the storage system to its optimal operating state. This procedure requires a manual takeover of the controller with the failed I/O module.
