Multi-storage device lifecycle management system
A multi-storage device lifecycle management system includes a server computing system having a plurality of devices and an operating system engine. The operating system engine identifies an estimated first device remaining lifetime for a first device, identifies an estimated second device remaining lifetime for a second device, and determines whether a difference between the estimated first device remaining lifetime and the estimated second device remaining lifetime is less than an estimated multi-device minimum end-of-lifetime difference. If so, the computing system distributes workload operations between the first device and the second device in order to cause the difference between the estimated first device remaining lifetime and the estimated second device remaining lifetime to be greater than or equal to the estimated multi-device minimum end-of-lifetime difference.
