Abstract: A method may include receiving a request for a memory page in a memory tier comprising a first memory device and a second memory device, wherein the first memory device has a first parameter and the second memory device has a second parameter, selecting, based on the first parameter and the second parameter, the first memory device, and allocating, based on the request, based on the selecting, the memory page from the first memory device. The selecting may include determining a first result based on the first parameter, determining a second result based on the second parameter, and comparing the first result and the second result. The determining the first result may include combining the first parameter with a first weight. The first weight may include a first scale factor, and the combining the first parameter with the first weight may include multiplying the first parameter and the first scale factor.

Abstract: A Solid State Drive (SSD) is disclosed. The SSD may include a host interface logic to receive a write command from a host and flash memory to store data. The SSD may also include an SSD controller, which may include storage for a just-in-time threshold and a tail latency threshold flash translation layer. The flash translation layer may invoke a just-in-time garbage collection strategy when the number of free pages on the SSD is less than the just-in-time threshold, and a tail latency-aware garbage collection strategy when the number of free pages is less than the tail latency threshold. The tail latency-aware garbage collection strategy may pair the write command with a garbage collection command.
