On a FlashArray//XR4, which port is enabled for the management service by default?

Consistent with previous FlashArray generations, the FlashArray//XR4 adheres to the standard port designation for administrative connectivity.

ETH0 is the primary port enabled for the management service by default.

When an Implementation Engineer first connects to a new //XR4 controller to perform the initial IP configuration, they utilize ETH0 (and often ETH1 for redundancy).

These ports are physically labeled for management and are logically separated from the data and replication traffic in the default configuration.

ETH2 and ETH3 are typically reserved or defaulted for replication traffic, while higher-numbered ports (like ETH10+) are used for host I/O or backend shelf connectivity on the R4 platform. Using ETH0 ensures immediate access to the Purity GUI and CLI without requiring custom port reconfiguration.
