The connections between storage systems require fibre channel cable
and GigaBit Interface Converters (GBICs) at each SP. If the
connections include extender boxes, then the distance between
storage systems can be up to the maximum supported by the
extender — generally 40-60 kilometers.
Without extender boxes, the maximum distance is 500 meters.
