Abstract
A method includes (a) receiving a setup command directing a computing device to create a protocol endpoint to allow a remote host device to access storage volumes of the computing device presented to the remote host through the protocol endpoint as virtual storage volumes, (b) in response to receiving the setup command, creating a logical storage device object representing the protocol endpoint, the logical storage device object having zero underlying storage capacity, (c) subsequent to creating the logical storage device object, receiving a command directed at the protocol endpoint, and (d) in response to receiving the command, processing the command by a driver stack on the computing device containing the logical storage device object representing the protocol endpoint, the driver stack being shorter than another driver stack on the computing device used to process storage commands directed at another logical storage device object having non-zero underlying storage.
