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: Apparatus and methods employing wormhole structures supporting ultra-high density optical routing systems. Microstructures comprising wormhole tunnels are formed in optical looms with wormhole openings arranged in patterns, such as a high-density XY grid. Optical fibers are inserted into respective wormhole tunnels, and sleeves are used to precisely align fiber ends. A rack loom comprising a wormhole backplane is fabricated in a similar manner, with wormhole openings arrayed in the same patterns. The sleeves comprise plug-receptacle sleeve pairs, where when an optical loom (or connector bar of the optical loom) face urged toward the front face of the rack loom, the plug and receptacle sleeves are mated, resulting in precise alignment of the optical fiber ends in the pairs of sleeves. Palpebral structures may also be fabricated to provide a self-cleaning function with optional lubrication.

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. In some embodiments, certain physical resources such as storage may be placed in racks that are in zones closer to the network switch and therefore use shorter data cables with lower latency. 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.
