According to embodiments of the invention, provide a kind of electric power system of server.
As shown in Figure 1, comprise according to the electric power system of the server of the embodiment of the present invention:
Multiple rack 1, be arranged in multiple servers of each rack of multiple racks 11;
Be positioned at the Power entry module 2 of each rack, the power supply parameter for the mainboard 3 according to multiple server is changed the input current received, and obtains the supply current of the mainboard 3 of multiple server and exports;
At least one busbar 4, busbar 4 comprises the cabinet busbar 41 being positioned at rack 1, in cabinet, busbar 41 is connected respectively with the mainboard 3 of Power entry module 2, multiple server, and in cabinet, busbar 41 is powered based on the mainboard 3 of supply current to multiple server for the supply current that receives from the Power entry module 2 in this rack 1.
Wherein, in one embodiment, Power entry module 2 according to the embodiment of the present invention comprises power module (not shown), Power entry module 2 is further used for exporting the supply current of the mainboard 3 of the multiple servers be converted to power module (not shown), to power to power module (not shown).
Wherein, in one embodiment, power module (not shown) according to the embodiment of the present invention is connected with busbar 41 in shown cabinet, the power module (not shown) Power entry module 2 be used in cabinet cannot receive input current, powered by the mainboard 3 of the multiple servers in the 41 pairs of racks 1 of busbar in cabinet.
In addition, in one embodiment, according to busbar 42 between the cabinet that the busbar 4 of the embodiment of the present invention also comprises between adjacent rack, between cabinet, busbar 42 is connected with busbar in cabinet respective in adjacent rack.
Wherein, in one embodiment, in multiple rack 1, there is Power entry module 2 in any one rack 1 when damaging, and in this cabinet comprising in the adjacent rack 1 ' of the rack 1 of the Power entry module 2 of damage, busbar 41 ' is further used for the supply current received to transfer to busbar 42 between corresponding cabinet;
Between this cabinet, busbar 42 is for transferring to busbar 41 in the cabinet in the rack 1 of the Power entry module 2 comprising damage by the supply current received, thus powers to the mainboard 3 of the multiple servers in this rack 1.
In addition, in one embodiment, the top according to the rack 1 of the embodiment of the present invention comprises opening 5, is positioned at the top of the cabinet busbar 41 of rack 1, and in 41 cabinets, busbar is connected to busbar 42 between the cabinet that is positioned between adjacent rack 1 and 1 ' by opening 5.
Preferably, in one embodiment, the Fig. 1 according to the embodiment of the present invention can find out, comprises two busbars 4 in rack 1 of the present invention, and is positioned at the sidewall being arranged on rack 1 of two cabinet busbar 41 symmetries of rack 1.
Preferably, in one embodiment, the mainboard 3 of the multiple servers in each rack 1 to be plugged in symmetrically arranged two cabinets between busbar 41 and to be connected with busbar 41 electric power in these two cabinets.
Preferably, in one embodiment, be arranged on the bottom in rack 1 according to the Power entry module 2 of the embodiment of the present invention, and be connected with the bottom fitting electric power of busbar 4.
Optionally, this electric power system comprises the PDM (not shown) being positioned at first cabinet of each row further, and city's electric current for receiving city's electric current, and is inputed to the Power entry module 2 in each rack by PDM (not shown).
Above-described embodiment for a better understanding of the present invention, is described in detail technical scheme of the present invention below in conjunction with an instantiation.
UPS can be omitted in the present embodiment, city's electric current is connected directly to PDM, and make PDM connect Power entry module in each rack, be equivalent to each rack like this and a Power entry module is only set, and do not need to make all to configure in each server in rack Power entry module, cause battery redundancy, Power entry module receives city's electric current from PDM, and voltage stabilizing process is carried out to civil power, the DC voltage of the supply voltage 12V of server master board is converted to (certainly by 220V alternating voltage, if server master board is it is desirable that the alternating voltage of 12V, then be converted to the alternating voltage of 12V), then the 12V DC power transmission after conversion is given busbar in two cabinets by Power entry module, and to the powered battery in Power entry module.Like this, multiple server master boards that in cabinet, the electric current after conversion just can input in rack by busbar carry out main board power supply; Meanwhile, the battery in Power entry module also can obtain sufficient power supply.
Because electric power system of the present invention is provided with battery in Power entry module; so when commercial power interruption (forced outage); battery in Power entry module in this rack just can be powered to the multiple server master boards in rack by busbar in cabinet, server (i.e. load) is maintained normally work and protect the software of server, hardware is not damaged.But also avoid as each server in cabinet all configures the tedious steps of Power entry module.
In addition, owing to being also connected by busbar between cabinet between different rack, material is thus formed a direct supply pond.That is, when the Power entry module in a certain rack damages, the Power entry module in two so adjacent with this rack racks can be powered for it, works on to make the load in this damage rack.Be specially, in Power entry module in rack, battery is installed, after the Power entry module of some racks damages, the rack of busbar between cabinet can be shared, just have shared the readiness time of battery, so when power-off, battery in different rack can be connected by busbar between cabinet, thus formed " direct supply pond ", the rack be so connected with this " direct supply pond " therefrom can obtain electric power, thus when achieving power-off the battery backup time share.
In sum, by means of technique scheme of the present invention, by arranging a Power entry module in each rack, thus eliminate the loaded down with trivial details of Power entry module is set in each server; And continue load supplying after power-off can being realized by Power entry module, namely achieve adjacent cell redundancy, achieve again power-off preparation time and share.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
