Abstract
A data storage system is implemented with an active power monitoring and control performed by a control node elected among a number of nodes. A real-time power monitoring information is supplied to the control node from, a power monitoring logic residing at each device in the system. The devices in the data storage system are pre-allocated with respective individual power budgets which are below the maximum power usage thereof. The power budgets of all the equipment cumulatively constitute a power budget assigned to the group of equipment. The control node controls dynamically and in real time power sharing between the plurality devices so that the devices with required power usage below the pre-allocated power budget can share their extra power credits with devices which are in need for extra power for performing its operation. The control node provides sharing of the power among the equipment in the data storage system with a goal of avoiding exceeding of the cumulative power budget assigned for the entire system or the cluster of the equipment.
