Abstract: Disclosed is a virtualization device communicating with a host device executing a virtual machine and including a computational storage virtualization (CSV) device, a storage device, and a computational device. A method of operating the virtualization device includes receiving a first request indicating a first address of the virtual machine, a second address of the storage device, and a read operation, acquiring a third address of a real machine and a fourth address of the computational device based on the first request, providing the storage device with a second request indicating the second address, the fourth address, and a redirection, providing the computational device with raw data based on the second request, providing the computational device with a third request indicating the third address, the fourth address, and a processing operation, generating processed data, and providing the host device with the processed data.

Abstract: Disclosed is an operation method of a storage virtualization device which communicates with a host device and a storage device set, includes a first submission queue (SQ) and a first completion queue (CQ), and supports a first virtual machine executable by the host device. The method includes fetching a first command of a first virtual submission queue (VSQ) of the first virtual machine, distributing the first command thus fetched to the first SQ, providing the first command of the first SQ to the storage device set, receiving, from the storage device set, a first completion indicating that the first command is processed, wherein the first completion is written in the first CQ, distributing the first completion of the first CQ to a virtualization layer, and writing the first completion thus distributed to a first virtual completion queue (VCQ) of the first virtual machine.

Abstract: A peripheral device controlling device according to an embodiment of the inventive concept includes a command queue for storing at least one Device to Device (D2D) command for data communication between a first peripheral device and a second peripheral device, a command parser for obtaining information related to the data communication from the at least one D2D command, and an orchestrator for controlling at least one of the first peripheral device and the second peripheral device to transfer data from the first peripheral device to the second peripheral device based on the acquired information.
