In one aspect, a method includes providing a splitter at a first storage array, receiving data from a host, storing the data on the first storage array, using a data protection appliance (DPA) to expose a device, continuously copying data stored on the first storage array to the device using the splitter and replicating the data to a second storage array using the DPA.

Splitter used in a continuous data protection environment

Described are techniques for indicating a state associated with a device. A request is received over a path for information about a device. A response to the request is sent. The response indicates a state regarding the device on the path. The response has a response status of good and a payload of a varying size. The payload is truncated at a location prior to that at which a device identifier for the device is expected. In accordance with the response, a state regarding the device on the path is determined.
