Samsung patents storage system that sorts data by speed needs
This patent describes a method where a computer's host tags data with a specific ID before sending it to storage. The storage device then places data requiring fast access into high-performance memory and slower data into standard memory based on that tag.
In the filing’s own words
A data storage method includes: in response to a stream ID carried by an IO write request of a host satisfying a first preset condition, writing data corresponding to the IO write request into a first storage unit; and in response to the stream ID carried by the IO write request satisfying a second preset condition, writing the data corresponding to the IO write request into a second storage unit, wherein the stream ID indicates write latency requirement information of the data corresponding to the IO write request, wherein a data write latency indicated by the stream ID satisfying the first preset condition is less than the data write latency indicated by the stream ID satisfying the second preset condition, wherein a read and write performance of the first storage unit is higher than the read and write performance of the second storage unit.
What exactly they claim (claim 1)
1. A host comprising: a data type determining unit configured to: determine a type of data corresponding to an Input/Output (IO) write request to a storage apparatus, wherein the storage apparatus includes a first storage unit and a second storage unit configured to support multi-stream; a stream identifier (ID) determining unit configured to: determine a stream ID corresponding to the IO write request based on the type of the data; and a transmission unit configured to: send the IO write request carrying the stream ID to the storage apparatus, the IO write request indicating for the storage apparatus to store data corresponding to the IO write request in the first storage unit in response to determining that the stream ID meets a first condition and to store the data corresponding to the IO write request in the second storage unit in response to determining that the stream ID meets a second condition, wherein the stream ID indicates data write latency of the data corresponding to the IO write request, wherein a first data write latency meeting the first condition is less than a second data write latency meeting the second condition, and wherein the first storage unit has higher read and write performance than the second storage unit.
