Fibre Channel over ATM
Direct FC-to-ATM conversion is supported by the Fibre Channel standards. However, currently, no
vendors sell direct FC-to-ATM gateways. If you have an ATM-based network, consider using
FC-to-GbE IP gateways, with an ATM blade residing on the Ethernet switch or IP router to convert
the GbE to ATM.
For detailed information about distance rules for Fibre Channel over ATM, see “ATM extension
Fibre Channel distance rules” (page 160).
