Abstract: A DPU creation system is described herein. The DPU creation system may receive an indication of one or more data processing unit (DPU) design specifications. The DPU creation system selects one or more protocols and one or more hardware modules for a DPU based on the DPU design specifications. The DPU creation system generates a simulated representation of the DPU by composing the one or more protocols and the one or more hardware modules. The DPU creation system tests the simulated representation of the DPU and determine whether to modify one or more aspects of the DPU based on test result data and design specifications. The DPU creation system may cause an aspect of the simulated representation of the DPU to be modified based on the determination. The DPU creation system may cause a hardware implementation of the DPU to be created based on the simulated representation of the DPU.

Abstract: Techniques for disaggregated storage acceleration are disclosed. A storage acceleration device offloads data plane operations from a host device. The storage acceleration device includes a transport acceleration system and a payload acceleration system. The transport acceleration system offloads, from the host device, transport operations such as encapsulating a payload into a transport message or decapsulating a transport message into a payload. The payload acceleration device offloads payload operations from the host device. The payload operations may include translating the payload from a fabric storage format to a local storage format. By offloading data plane operations from the host device, the storage acceleration device frees computing resources of the host device.

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: 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.
