Abstract: Example implementations relate to selectively enabling backup power to nodes. For example, a system includes a plurality of compute nodes, where each node includes a plurality of loads. The system also includes at least one backup power supply and control module coupled to the nodes and to the at least one backup power supply. The control module is to selectively enable an output of power from the at least one backup power supply to the nodes based on a comparison of a power capacity of the at least one backup power supply and a backup power demand of the nodes.

Abstract: Techniques for reducing power consumption of a storage controller are provided. An example method includes determining a back-end bandwidth of a storage system, wherein the back-end of the storage system includes a storage drive communicatively coupled to a storage controller. The method also includes determining a front-end bandwidth of the storage system, wherein the front-end of the storage system includes a front-end bus coupling the storage controller to a host. The method also includes computing a target back-end memory bandwidth based on the back-end bandwidth and computing a target front-end memory bandwidth based on the front-end bandwidth. The method also includes reducing power consumption of the storage controller by reducing a clock frequency of a memory device of the storage controller based on the greater of the target back-end memory bandwidth and the target front-end memory bandwidth.

Abstract: Examples of runtime drive detection and configuration are disclosed. In one example implementation according to aspects of the present disclosure, a computer implemented method includes detecting, by a computing system, that a drive is connected to the computing system during a runtime using a sideband signal of the drive. The method further includes determining, by the computing system, a drive type for the drive. Additionally, the method includes configuring, by the computing system, during a runtime, a PCIe multiplexer based on the determined drive type.
