摘要： A gas replenishment component for an electronic enclosure is described. A main body defines a containment volume. The main body is sealed about the containment volume. A charging gas is contained in the containment volume. The containment volume has less than 5% N2. The main body defines a diffusive area that is permeable to the gas. A reversible seal obstructs the diffusive area.

摘要： A storage system with temperature control. The system includes a plurality of storage devices such as solid state drives, a system controller such as a baseboard management controller, and one or more cooling fans. Each storage devices includes a controller configured to estimate the heat load in the storage device and/or an effective temperature, resulting from operations performed in the storage device. The system controller employs active disturbance rejection control to adjust the fan speed based on the estimated heat loads, the estimated temperatures, and/or the sensed internal temperatures, of the storage devices.
