摘要： A method of operating a storage system is provided. The method includes executing an operating system on one or more processors of a compute device that is coupled to one or more solid-state drives and executing a file system on the one or more processors of the compute device. The method includes configuring the compute device with one or more replaceable plug-ins that are specific to the one or more solid-state drives, and executing a flash translation layer on the one or more processors of the compute device, with assistance through the one or more replaceable plug-ins for reading and writing the one or more solid-state drives.

摘要： A method for processing blocks of flash memory to decrease raw bit errors from the flash memory is provided. The method includes identifying one or more blocks of the flash memory for a refresh operation and writing information regarding the identified blocks, to a data structure. The method includes issuing background reads to the identified blocks, according to the data structure, as the refresh operation. The method may be embodied on a computer readable medium. In some embodiments the background reads may be based on a time based refresh responsive to an increase in raw bit error count in the flash memory over time.
