Methods and Systems for Flash Buffer Sizing

摘要

The embodiments described herein are used to allocate memory in a storage system. The method includes, at a memory controller in the storage system, determining a current memory allocation for a set of memory devices, wherein the set of memory devices is formatted with a ratio of first storage density designated portions to second storage density designated portions in accordance with the current memory allocation. The method further includes detecting satisfaction of one or more memory reallocation trigger conditions. The method further includes, in response to detecting satisfaction of one or more memory reallocation trigger conditions, modifying the ratio of the first storage density designated portions to the second storage density designated portions in the set of memory devices to generate a second memory allocation for the set of memory devices.

1. A method of allocating memory in a storage system that comprises a memory controller and a set of memory devices, the set of memory devices comprising a plurality of memory portions, the method comprising:
at the memory controller:
determining a current memory allocation for the set of memory devices, wherein the set of memory devices is formatted with a ratio of first storage density designated portions to second storage density designated portions in accordance with the current memory allocation;detecting satisfaction of one or more memory reallocation trigger conditions; andin response to detecting satisfaction of one or more memory reallocation trigger conditions, modifying the ratio of the first storage density designated portions to the second storage density designated portions in the set of memory devices to generate a second memory allocation for the set of memory devices.
