Reconfigurable storage device

A host that reconfigures a storage device, comprising:

• a memory;
• a processor coupled to the memory;
• and
• a first software component executed by the processor that is configured to:
• receive user requirements including a service level agreement (SLA) specifications;
• convert the SLA specifications to feature settings based on a device profile;
• determine optimal combinations of the feature settings;
• generate multiple plans comprising configuration commands from the optimal combinations;
• and
• select one of the plans considering performance and status of the storage device and the user requirements;
• and
• a second software component executed by the processor that is configured to:
• receive the selected plan;
• send the plan to the reconfigurable storage over a configuration channel;
• receive a response from the storage device;
• and
• iterate the plans in case of a negative response from the storage device;
• and
• a third software component executed by the processor that is configured to:
• collect the device profile and send the device profile to the configuration planner;
• monitor the one or more logical devices created on the storage device, and determine if all the user requirements are satisfied;
• and
• notify the configuration planner to adjust the plan based on the device profile in case of a SLA violation.

A reconfigurable storage device, comprising:

• a main storage;
• a processor coupled to the main storage;
• and
• a software component executed by the processor that is configured to:
• receive a plan comprising at least one configuration command containing feature settings;
• check availability and applicability of the feature settings in the plan based on a device profile;
• when the plan is not valid, rejecting the plan and rolling back any changes that were made by the plan;
• validating the plan when both availability and applicability of the feature settings are true;
• executing the plan, and updating the device profile;
• and
• creating one or more logical devices on the reconfigurable storage device by associating the executed plan with a storage space.
