Storage System and Method for High-Correlation Data Analysis with Unified Time Mapping

A method comprising:

• performing the following in a host in communication with a storage system comprising a memory:
• synchronizing a clock of the host with a timing reference configured to coordinate playback of audio and video in a data stream so that corresponding audio and video segments in the data stream are presented at a same time;
• sending the data stream and the timing reference to the storage system, wherein the host and the storage system use different time domains;
• and
• receiving metadata from the storage system tagged with a time stamp generated by a clock of the storage system, wherein the clock of the storage system is synchronized to the timing reference of the data stream, and, as a result, the time stamp is in the host's time domain.

A storage system comprising:

• a memory;
• means for receiving a data stream from a host, wherein the data stream comprises a clock signal configured to coordinate playback of audio and video in the data stream so that corresponding audio and video segments in the data stream are presented at a same time;
• means for synchronizing a clock of the storage system with the clock signal of the data stream;
• means for tagging metadata with a time stamp generated by the clock of the storage system, wherein because the clock of the storage system is synchronized to the clock signal of the data stream, the time stamp tagged to the metadata is in a time domain of the host;
• and
• means for sending the tagged metadata to the host.
