Abstract: In some examples, a control unit is configured to adjust charge termination voltage of a rechargeable energy storage device. The control unit is adapted to charge the rechargeable energy storage device to a charge termination voltage where the rechargeable energy storage device has capacity to support peak load but comes close to a system shutdown voltage after supporting peak load. The control unit is also adapted to increase the charge termination voltage if a voltage of the rechargeable energy storage device is near a system shutdown voltage after supporting peak load.

Abstract: Technologies for connecting data cables in a data center are disclosed. In the illustrative embodiment, racks of the data center are grouped into different zones based on the distance from the racks in a given zone to a network switch. All of the racks in a given zone are connected to the network switch using data cables of the same length.

An orchestrator server may, in some embodiments, schedule workloads or create virtual servers based on the different zones and corresponding latency of different physical resources.
