Abstract
An apparatus, system, and method are disclosed for caching data. A storage request module detects an input/output (“I/O”) request for a storage device cached by solid-state storage media of a cache. A direct mapping module references a single mapping structure to determine that the cache comprises data of the I/O request. The single mapping structure maps each logical block address of the storage device directly to a logical block address of the cache. The single mapping structure maintains a fully associative relationship between logical block addresses of the storage device and physical storage addresses on the solid-state storage media. A cache fulfillment module satisfies the I/O request using the cache in response to the direct mapping module determining that the cache comprises at least one data block of the I/O request.
