Determining adjustments to the spare space in a storage device unavailable to a user based on a current consumption profile of a storage device

An apparatus to manage spare space in a storage device to:

• maintain a write amplification function providing spare space percentages for different write amplifications to optimize performance at the storage device;
• determine a remaining storage write rate of remaining writes permitted at the storage device;
• determine an adjustment factor to a current storage write rate to result in the remaining storage write rate;
• determine an adjusted write amplification by applying the adjustment factor to a current write amplification;
• determine from the write amplification function an adjustment to spare space for the adjusted write amplification, wherein the spare space comprises overprovisioned storage space not comprising user accessible storage;
• and
• reconfigure the spare space and free space available to a user to adjust the spare space by the adjustment to spare space.

A system in communication with a storage device to manage spare space in the storage device, comprising:

• a processor to execute computer instructions in a memory device to:
• maintain a write amplification function providing spare space percentages for different write amplifications to optimize performance at the storage device;
• determine a remaining storage write rate of remaining writes permitted at the storage device;
• determine an adjustment factor to a current storage write rate to result in the remaining storage write rate;
• determine an adjusted write amplification by applying the adjustment factor to a current write amplification;
• determine from the write amplification function an adjustment to spare space for the adjusted write amplification, wherein the spare space comprises overprovisioned storage space not comprising user accessible storage;
• and
• send a resize command to the storage device having as a parameter the adjustment to the spare space for the adjusted write amplification to cause the storage device to reconfigure the spare space and free space available to a user by the adjustment to the spare space in the parameter of the resize command.

A system, comprising:

• a host including a processor and memory having computer instructions executed by the processor;
• and
• a storage device, a spare space adjustment module implemented in one of the host and the storage device to:

• determine a remaining storage write rate of remaining writes permitted at the storage device;
• determine an adjustment factor to a current storage write rate to result in the remaining storage write rate;
• determine an adjusted write amplification by applying the adjustment factor to a current write amplification;
• determine from the write amplification function an adjustment to spare space for the adjusted write amplification, wherein the spare space comprises overprovisioned storage space not comprising user accessible storage;
• and
• cause the storage device to reconfigure the spare space and free space available to a user by the adjustment to spare space.
