During an iSCSI deployment, if a customer requests a change from twinax cables to fiber-optic cables, two NetApp tools can be used to verify the supported port speeds and transceivers:

Hardware Universe (HWU): This tool is essential for determining the supported transceivers and port speeds for NetApp hardware. It provides detailed information on hardware compatibility, including supported transceivers, cables, and port speeds, which helps ensure that the selected components are compatible with the NetApp storage system.

Interoperability Matrix Tool (IMT): The IMT provides comprehensive compatibility information between NetApp products and third-party components. It includes details on supported transceivers and port speeds, ensuring that any changes made to the network connections are supported and will function correctly in the given configuration.
