Abstract
An apparatus in one embodiment comprises a host device comprising a processor coupled to memory. The host device is configured to communicate over a network with at least one storage system. The host device is further configured to generate a user space block device and to generate a kernel space block device corresponding to the user space block device. The host device is further configured to receive an input-output operation at the kernel space block device from an application executing on the host device and to transfer the input-output operation from the kernel space block device to the corresponding user space block device. The host device is further configured to submit the input-output operation to the at least one storage system based at least in part on the user space block device.
