Abstract
Emulating a Fiber Channel connection to a workstation includes providing a first Fiber Channel emulator that exchanges data between the workstation and a data storage device using a connection mechanism between the workstation and the data storage device, wherein the connection mechanism is incompatible with a Fiber Channel connection and handling emulator events received at the emulator, wherein the events include message events, state events, and driver events. The first Fiber Channel emulator may act as an I/O subsystem providing FICON communication capability. The connection mechanism may be an Ethernet connection. The first Fiber Channel emulator may send a message to a link layer which sends a message to an SLI driver which builds a ring queue message and passes the message to an emulated hardware layer which packages up the message indicating status. The message may be sent using the connection mechanism.
