Abstract
A storage system includes a plurality of solid-state storage devices and a storage controller operatively coupled to the plurality of solid-state storage devices, the storage controller including a processing device, the processing device to receive, from a first solid-state storage device of the plurality of solid-state storage devices, an indication that data stored at the first solid-state storage device is affected by read disturb. In response to receiving the indication, the processing device is further to identify a second solid-state storage device of the plurality of solid-state storage devices for the relocation of the data and transmit, to the first solid-state storage device, a command comprising information associated with the relocation of the data from the first solid-state storage device to the second solid-state storage device, wherein the command causes the first solid-state storage device to relocate the data to the second solid-state storage device.
