Proactive scheduling of background operations for solid state drives

A solid state storage device (SSD), comprising:

• a non-volatile storage area divided into a plurality of pages each having a first size, wherein the plurality of pages are grouped into a plurality of blocks each having a larger second size, wherein read operations are performed on individual pages of the plurality of pages, and background erase operations are performed on individual blocks of the plurality of blocks;
• a device controller coupled to the non-volatile storage area, the device controller to:
• perform a background erase operation on a first block of the plurality of blocks;
• receive a request from an input-output controller to read data from at least one page of the plurality of pages that is included in the first block on which the background erase operation is performed;
• initiate recovery of the at least one page to reconstruct the data;
• and
• send the data to the input-output controller.

A non-transitory computer readable storage medium having instructions that, when executed by a processing device of a storage server that manages a plurality of solid state storage devices (SSDs), cause the processing device to perform operations comprising:

• receiving, by the processing device, a request to read data;
• determining a first SSD of the plurality of SSDs on which the data is stored;
• determining that the first SSD is performing a background operation;
• determining whether the data is located on a block of the first SSD that will be unavailable during the background operation;
• responsive to determining that the data is located on the block of the first SSD that will be unavailable during the background operation, reconstructing the data by the processing device based on additional data on one or more remaining SSDs of the plurality of SSDs;
• and
• generating a response to the request, the response comprising the data.
