Abstract
Techniques are provided for latency-based detection of storage volume type. One method comprises sending read commands using a predefined read command sequence to a recipient storage volume, wherein the predefined read command sequence specifies a request size and/or an offset of at least two of the read commands, and wherein an entity associated with a recipient storage volume of a predefined storage volume type is configured to insert a predefined delay before sending a response to at least one of the read commands when the entity detects the predefined read command sequence; evaluating whether the response to at least one of the read commands comprises the predefined delay; and determining whether the recipient storage volume is the predefined storage volume type based on a result of the evaluating. The recipient storage volume may comprise a storage volume and/or a storage data client that exposes a virtual storage volume.
