Abstract
Described are techniques for providing a plurality of logical connections over a physical connection. A login frame is transmitted for each of the plurality of logical connections from an initiator port to a target port. The login frame includes a payload comprising a first identifier of a virtual port associated with the initiator port. Upon receiving the login frame, a login acceptance frame is transmitted from the target port to the initiator port and includes a second identifier of a virtual port associated with said target port in the payload. The initiator and target ports are included in hardware components in compliance with a version of a protocol that does not support multiple logical connections over a same physical connection. Each logical connection is established as a result of processing including transmitting a login frame and a login acceptance frame.
