Abstract
A method, corresponding control logic, and a correspond system for detecting a virtual storage volume. The method includes: determining a first access pattern for a read operation of a target storage volume; monitoring a second access pattern of at least one other storage volume of a computer system during the read operation; determining a correlation between the first access pattern and the second access pattern; and deriving that the target storage volume is a virtual storage volume if the determined correlation is above a predefined threshold.
