Abstract:
1. A method of operating a storage system, the method comprising: a storage controller receiving a first life parameter of a first storage device; determining if the first life parameter indicates that the first storage device has a remaining life that is less than a pre-determined life parameter threshold; in response to the remaining life being less than the pre-determined life parameter threshold, designating the first storage device for replacement; in response to designating the first storage device for replacement, determining if the first storage device is at an end of life; in response to the first storage device being at the end of life, transferring data from the first storage device to a second storage device that has a remaining life which is not less than a corresponding life remaining parameter threshold for that second storage device; and in response to completion of the transferring of the data to the second storage device, disabling the first storage device.
