Abstract
Method and apparatus for managing data transfers. In some embodiments, first and second storage devices respectively include first and second controllers, first and second local memories, and first and second non-volatile memories (NVMs). A virtual controller memory buffer (CMB) is formed from a dedicated portion of each of the first and second local memories for control by a host device. The first controller receives a virtual command set from the host device, and extracts a first local command to transfer data between the host device and the first NVM. In some cases, the second controller also receives the virtual command set and concurrently extracts a different, second local command to transfer data between the host device and the second NVM. Alternatively, the first controller may extract and forward the second local command to the second controller. The first and second NVMs may form an NVMe (Non-Volatile Memory Express) namespace.
