Abstract
Methods and systems of causation of a data read operation against a first storage system by a server associated with a second storage system according to a host generated instruction are disclosed. In an embodiment, a method of causing a data read operation against a first storage system, the data read operation performed by a server associated with a second storage system according to a machine-readable instruction generated by a host directly associated with the first storage system. The method further includes saving data from the host to the first storage system, creating a record of at least one data write comprising the data saved to the first storage system, and using a variable contained in the record to process a mapping scheme resulting in knowledge of at least one physical offset in the first storage system to receive the at least one data write.
