Summary of the invention
A kind of method that technical assignment of the present invention provides a kind of reliability that greatly improves electric power system, realizes no cable connection, maintains easily to RACK system concentration supply power.
Technical assignment of the present invention realizes in the following manner, adopts N+1 power module parallel redundancy supply power mode to produce+the 12V bus of power by the intermediate power supplies backboard, comes to power to server node in the RACK system; Adopt the power supply of two level power supplies, one level power supply adopts multi-power module parallel operation mode, be N+1 power module parallel redundancy supply power mode, realize of the conversion of 220V AC power, output in the RACK system on each server node by the 12V DC power supply to the 12V DC power supply; The DC-DC secondary power supply that each server node plate carries is changed the 12V power supply, provide the required 12V of each server node, 5V, 3.3V, 5VSB ,-clock signal of 12V voltage and PS-ON and PowerGood switching on and shutting down; Power supply module and server node all adopt the connected mode of golden finger to be connected one by power supply backplane.
The N+1 power module parallel redundancy supply power mode of one level power supply is by the power module of in-parallel operation, and distributed power source is provided; All power module parallel runnings, the load that equalization of incidence is current, the power module array is put a power power-supply module than rated capacity polygamy, when a power module breaks down, the trouble power module is disconnected from load, other power module will be supported all loads immediately, make it be the power supply of RACK system uninterruptedly; One level power supply power module is powered to each server node of RACK system by power supply backplane; The design of one level power supply power module has the functional circuit of fault detect, location, isolation, warning, hot swap, supports hot plug, and also designing in the level power supply power module has overvoltage, overcurrent, the too high safety protective circuit of temperature.
One level power supply adopts multi-power module parallel operation mode, optimizes the output coupled modes on the power distribution plate, guarantees the current-sharing output between power module.N+1 power module parallel redundancy supply power mode has not only effectively reduced the power supply cost, but also guarantees that fully RACK system power supply do not interrupt.The design of one level power supply has the functional circuit of fault detect, location, isolation, warning, hot swap, when breaking down in the power module subsystem, sends information by the administrative unit in the power module, realizes can monitoring efficiently and the on-line maintenance function; Design has overvoltage, overcurrent, the too high safety protective circuit of temperature in the one-level power subsystem; Monitor And Control Subsystem can be made preventive measures according to the abnormal conditions of power supply itself and system, avoids mortality infringement and other security incident that the RACK system is brought
One level power supply adopts 1 group of 3+1 power module parallel redundancy supply power mode, the rated output power of each power module configuration 5000W, total maximum rated power 15000W.
Secondary power supply is provided with and prevents the node power-off protecting circuit to what each server node in the RACK system provided short-circuit protection function; The fault in case certain server node is short-circuited, secondary power supply can disconnect immediately and stop to this server node power supply; Secondary power supply adopts the hot plug design.
Secondary power supply improves the versatility of each server node motherboard in the RACK system and provides short-circuit protection function (this function mainly is to prevent in the RACK system that certain server node is short-circuited fault and causes) to each server node in the RACK system.The fault in case certain server node is short-circuited, secondary power supply can disconnect immediately and stop to this server node power supply.Thereby avoid the whole RACK system generation loss of power accident.The beneficial effect of this function is: when placing multiple servers in the RACK system, can not influence the reliable and stable operation of other server in the same rack because of the damage of certain server secondary power supply wherein.
Before entering the RACK system, three-phase 380V power supply adopts rack supply socket (Power Distribution Unit is called for short PDU) to convert single-phase 220V power supply to, and single-phase 220V power supply is the intrasystem power module power supply of RACK.The three-phase 380V electricity that enters rack converts N to by two PDU and organizes single-phase 220V electricity, is respectively the intrasystem power module power supply of RACK.Why adopt PDU and do not adopt the power supply plan of common power insert row, mainly be for avoiding occurring RACK system safety hidden danger, this is because PDU compares with the common power socket, its circuit design arrangement is more reasonable, stricter, the safe time between failures of quality and standard is long, Plug Action is frequently and not fragile, installation and maintenance are more flexible, can fundamentally stop the common power socket because of loose contact, the little frequent outage that causes of load, burn, potential safety hazard such as fire.
Power supply backplane is fixed in the level power supply stuck-module.
A kind of method to RACK system concentration supply power of the present invention has the following advantages:
1, N+1 Redundancy Design: a level power supply adopts the N+1 Redundancy Design, has not only effectively reduced the power supply cost.And can under the situation that any 1 power module lost efficacy, still guarantee RACK system operate as normal;
2, level power supply design has the functional circuit of hot swap, and hot plug is supported in the power module design, can not have the instrument dismounting, and the personnel of maintaining easily change the trouble power module, and after the trouble power module was changed, power module can return to normal condition again;
3, fault can detect and handle design certainly: when power module breaks down in the power subsystem, the trouble power module can be isolated, send warning information to Monitor And Control Subsystem; Overvoltage, overcurrent, temperature exceeding standard etc. occur when unusual, the functional circuit in the power subsystem takes to increase heat-sinking capability or action such as outage automatically automatically, avoids the harmful effect to power supply and whole RACK system;
4, node short-circuit protection function: the fault in case certain server node is short-circuited, secondary power supply can disconnect immediately and stop to the power supply of this server node, thereby avoid the whole RACK system generation loss of power accident;
5, the use of rack supply socket: can fundamentally stop the common power socket because of loose contact, the little frequent outage that causes of load, burn, potential safety hazard such as fire;
6, power supply module and computing node all adopt the connected mode of golden finger to be connected one by power supply backplane, have greatly improved the reliability of electric power system, realize no cable connection, maintain easily;
7, reasonable in design, easy to use, thereby, have good value for applications.
