Abstract:
In a computer system having at least one main communications path, a system power control network providing a power control path independent of the at least one main communications path, a plurality of system devices including direct access storage devices, direct access storage device controllers, and at least one power supply, a smart direct access storage device spin-up system comprising:a system power control network processor coupled to independently control and monitor the computer system direct access storage devices and the at least one power supply with the system power control network, and having and executing a program and being operational at computer system initialization to independently:determine, using the system power control network, system device power requirements and system power supply capabilities;based on the determining, calculate a maximal number of direct access storage devices which can be started at one time; andstart the maximal number of direct access storage devices calculated before the computer system initialization has completed initialization of the direct access storage device controllers.
