1. A data storage system, comprising:
a first storage channel for providing a connection to a first storage device;
a first controller coupled to the first storage channel;
a second storage channel for providing a connection to a second storage device;
a switch coupled to separate the first storage channel from the second storage channel in a first state and to connect the
first storage channel to the second storage channel in a second state; and
a control circuit configured to cause entry of the switch in the second state in response to detecting a failure of the first
controller.
