Abstract
A data storage system includes a first storage processor including a first memory device; a second storage processor including a second memory device; and a third memory device coupled to the first storage processor and the second storage processor. The first and second storage processors are interconnected to enable mirroring of data between the first memory device and the second memory device. During a first mode of operation, data processed by the first storage processor and the second storage processor is mirrored between the first memory device and the second memory device and, during a second mode of operation, data processed by the first storage processor is mirrored from the first memory device to the third memory device.
