Abstract
Embodiments of the present disclosure relate to a method for I/O data transmission in a Hyper-Converged Storage System (HCSS). The HCSS comprises at least one storage node having at least one device constructed with virtualization technology and a storage I/O processing module for accessing persistent storage resource of the HCSS. According to the method, an I/O request of a first type is received from the device by a System Disk front-end driver (SFD), wherein the I/O request of the first type is an I/O request to a system disk of the device. The I/O request of the first type and its corresponding response of a first type are transferred by the SFD between the device and the storage I/O processing module via a first shared memory, wherein the first shared memory is created by allocating a first memory region of the HCSS as the first shared memory.
