Abstract
Techniques are provided for dual port storage device emulation. A switch is configured with a first virtual switch to provide a first computing device with access a first single port device through a first port and a second port. The switch is configured with a second virtual switch to provide a second computing device with access to a second single port device through a third port and a fourth port. In response to determining that the first computing device has experienced a failure, the first virtual switch and the second virtual switch are reconfigured to provide the second computing device with access to the first single port device through the second port and access to the second single port device through the fourth port. The first computing device is disconnected from accessing the first single port device through the first virtual switch.
