Method and System for Cooling Radiators of Servers using Integrated Sparing

Disclosed is a method and system for cooling pumps, blowers, power supplies and sensors used in radiators of servers using integrated sparing. The integrated sparring is applied to all mechanical components sensors and drive circuitry that may be prone to failure.

In accordance with the method and system, an N+2 hardware arrangement is provided as illustrated in Fig. 1.

Figure 1

The N+2 configuration includes pumps and attached drive card where N mode =1.

Additionally, the N+2 configuration includes blowers and drive card attached to the blowers where N mode = 2. Further, the N+2 configuration includes a thermistor in

water cooling processors and level sensors in reservoir used during filling and

operation where N mode=1. Still further, the N+2 configuration includes leak sensors in both Radiator pan and in System Pan where N mode = 1 in each case.

The system includes hardware which consists of three pump Field Replaceable Unit (FRU) assemblies in a vertical orientation for ease of fill and drain in a radiator

Water after cooling the server drawers is received. Any one pump of the three pump

FRU assemblies provides entire water flow required for cooling. One pump is run at a time to improve pump life cycle. Each pump is run periodically. The drive card is integrated into the pump FRU assembly as the repair frequency (due to Integrated Sparing) is low and cost of replacing the FRU pump assemblies is inconsequential. This enables 100% accuracy in identifying right component that needs to be replaced.

The water exits the pump and enters a common manifold that feeds the air to water heat exchanger or Radiator. The hardware includes leak sensors that are located in a pan under the radiator as well as a larger pan that is able to handle entire liquid contents of the server should that ever be required. The water is fed to a supply manifold that is embedded with an Integrated Sparing thermistor that monitors effectiveness of the cooling system. The heat from the servers is ejected out of the radiator by blowing air over the heat exchanger. The air movement is created by an Integrated Sparing blower system when two blower assembl...
