Abstract
Architecture for data communications optimization based on generating and communicating “intents” or “hints” to a storage device and faster/slower solid state memory optimization. Data destined for storage on the storage device (capable of hints processing) can be bracketed to take advantage of improved performance associated with the hints processing. Data can be communicated in block format such that individual series of block exchanges can occur. Hints processing can be optional at the storage device. When communicated to the storage device firmware facilitates optimization of internal data flow and device operation. A write optimization schema is provided for storage system such as solid state storage devices. For example, frequently-modified data can be stored in faster memory to provide more efficient overall application data processing, and less-frequently modified data can be processed into and out of lower cost (or slower) memory.
