Abstract
A drive assisted storage controller system includes a first storage device that is coupled to a bus that includes a data path and a control path. The first storage device receives via the control path from a storage controller, a first peer-to-peer write command that identifies a host memory address included in a memory system, a first storage location provided in the first storage device, and a second storage location provided in a second storage device coupled to the bus. The first storage device retrieves, via the data path from the host memory address, first write data such that the first write data is not provided through the storage controller. The first storage device provides, via the control path to the second storage device, a second peer-to-peer write command that includes the second storage location. The second peer-to-peer write command causes the second storage device to retrieve the first write data from the first storage device via the data path.
