Data Storage Mechanism Using Storage System Determined Write Locations

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed by a storage system controller of a storage system comprising a storage medium, causes the storage system controller to:

• receive a write request to write at least one block of data to the storage medium of the storage system, wherein the write request does not specify a location on the storage medium to which to write the at least one block of data;
• determine a current position of a write mechanism of the storage system relative to the storage medium;
• determine a location on the storage medium to write the at least one block of data based on the current position of the write mechanism;
• send a notification, from the storage system controller to a host system from which the write request was received, identifying the location of the at least one block of data on the storage medium as determined by the storage system controller;
• and
• write the at least one block of data to the determined location on the storage medium.

An apparatus, comprising:

• a storage system controller;
• and
• a storage medium coupled to the storage system controller, wherein the storage system controller comprises logic configured to:
• receive a write request to write at least one block of data to the storage medium of the storage system, wherein the write request does not specify a location on the storage medium to which to write the at least one block of data;
• determine a current position of a write mechanism of the storage system relative to the storage medium;
• determine a location on the storage medium to write the at least one block of data based on the current position of the write mechanism;
• send a notification, from the storage system controller to a host system from which the write request was received, identifying the location of the at least one block of data on the storage medium as determined by the storage system controller;
• and
• write the at least one block of data to the determined location on the storage medium.
