摘要
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.
說明書
The host devices 102 comprise respective sets of IO queues 110-1, 110-2, . . . 110-N and respective functionality for implementing interface logic 114-1, 114-2, . . . 114-N. In some embodiments, one or more of the host devices 102 may also optionally comprise respective MPIO drivers, e.g., MPIO drivers 112-1, 112-2, . . . 112-N. The MPIO drivers 112 collectively comprise a multipath layer of the host devices 102. In some embodiments, the MPIO drivers 112 may comprise functionality for implementing the interface logic 114.
