Abstract

A method includes programming an FPGA based controller of a master blade with a power scheme. The master blade receives a first power management signal from the master blade and slave blades. The master blade transmits a second power management signal to itself and to the slave blades responsive to the first power management signal. The master blade receives a third power management signal from itself and the slave blades. The power scheme controls an order and delay in which the second power management signal is transmitted to the first master blade and the slave blades. The power scheme controls an order and delay in which the third power management signal is received from the master blade and the slave blades. The system can be expanded by connecting the master blades to a grand master blade and multiple grand master blades to a great grand master blade.

Dependent claims

A computer-implemented method, comprising:

programming a Field Programmable Gate Array (FPGA) based controller of a master blade with a power scheme, wherein the master blade is connected to one or more slave blades;
receiving, using the FPGA based controller of the master blade, a first power management signal from the master blade and one or more slave blades, wherein the master blade and the one or more slave blades operate in a first mode of operation;
transmitting, using the FPGA based controller and based on the power scheme, a second power management signal from the master blade to the master blade and to the one or more slave blades in response to the first power management signal, the master blade and the one or more slave blades operating in a second mode of operation in response to the second power management signal;
and
receiving, using the FPGA based controller and based on the power scheme, a third power management signal from the master blade and the one or more slave blades, wherein the third power management signal is received in response to the second power management signal and is indicative of the master blade and the one or more slave blades operating in the second mode of operation.
