A method and a computer program product executed by a processor may include or perform various operations. The operations include periodically reading a wear level for each of a plurality of storage devices operating in a multi-tiered storage system which includes a first storage tier and a second storage tier that is a lower tier than the first storage tier. At least one storage device operates in the first storage tier and at least one storage device operates in the second storage tier. The operations further include identifying a first storage device of the plurality of storage devices that is operating in the first storage tier and has a wear level that is higher than an average wear level for the plurality of storage devices. The operations additionally include causing the first storage device to switch from operating in the first storage tier to operating in the second storage tier.

Battery monitoring systems having conductive strips and related methods are disclosed herein. According to an aspect, a battery monitoring system includes a conductive strip having a first end and a second end. The system also includes conductivity measurement circuitry operatively connected to the first end and the second end of the conductive strip. The conductivity measurement circuity is configured to indicate whether conductivity between the first end and the second end meets a predetermined threshold. Further, the system includes a strap attached to at least one of the first end and the second end, configured to attach to a battery, and configured to apply tension to the conductive strip when attached to the battery.

Power distribution systems having a bi-directional link for delivery of power between each other are disclosed. According to an aspect, a PDU includes a first power inlet configured to receive electric power from a power source. The PDU includes a second power inlet configured to receive electric power from another power distribution unit. The PDU also include an electric power router configured to determine whether the power source is in a fault condition for delivering electric power to the first power inlet. Further, the electric power router is configured to communicatively engage the other PDU for managing receipt of electric power from the other PDU based on the fault condition. The electric power router is configured to receive, at the second power inlet, electric power from the other PDU. The electric power router is also configured to route, to power outlets, the electric power received from the other PDU.
