Embodiment
For the deficiency at available data center, the present invention designs and makes up from the several aspects of driving power, power supply-distribution system, server system of data center.
1, microserver Clustering.Adopt the microserver cluster to replace a conventional server group of planes among the present invention, microserver is made of a plurality of computing nodes, the CPU of each computing node is the computing node SOC chip of independent brand, special use, and the CPU core dominant frequency is low, computing node is simple, but quantity is many.Because chip power-consumption and dominant frequency are 3 powers relations, and with number of chips be the near-linear relation, so, with One's name is legion, hang down the calculated performance that the computing node of dominant frequency approaches high primary frequency CPU, can be under equal calculated performance, the decrease Overall Power Consumption.The microserver cluster has the multiple advantages such as high density, low-power consumption, high-performance, high reliability, enhanced scalability.
2, sun power main supply power technology.It is the main power supply of data center that the present invention adopts solar photovoltaic assembly, and data center surpasses 80% energy source in the sun power of cleaning, and is good such as illumination condition, can reach 100% solar poweredly, has realized the energy-saving and emission-reduction of data center, environmental protection.External electrical network is done Emergency use at sunshine in the inadequate situation only as backup battery, has reduced the input of outside electric power network.
3, the embedded ups system of microserver.Among the present invention, microserver itself can compatible direct current with exchange the two-circuit input, and embedded ups system, forming distributed UPS disposes, compared to the centralized UPS installation method of tradition, can make power fail localization, move more stablely, reliable, reduce simultaneously disposable Large UPS construction input.
4, high voltage direct current power supply-distribution system design.The present invention adopts the direct current standard to carry out the design and establishing of power supply-distribution system, and the direct current scope is DC180V-DC400V.The electricity that solar photovoltaic assembly sends is direct current, directly concentrates UPS battery group or the embedded UPS battery of server, does not need to do any conversion of AC-DC therebetween.Be different from the design of traditional AC220 and AC380 electric power system fully, reduced repeatedly the loss that the power supply conversion causes, improved energy utilization rate.
The below highlights the energy-saving principle of microserver cluster:
The power consumption of server master board concentrates on the CPU chip, reduce the cpu chip power consumption, just can effectively reduce server power consumption, and then reduce the electricity damage of the power consumption of cooling-down air conditioner, proportional minimizing power supply-distribution system, reach the purpose of the whole power consumption of decrease data center.The consumption reduction of cpu chip is the key of the whole consumption reduction of data center.The power consumption of the every reduction of chip-scale IW, the power-dissipation-reduced amount of a series of equipment such as the power supply conversion, distribution system, UPS, refrigeration system and the transformer that bring therefrom will reach 2.68-2.84W.The energy-saving and cost-reducing of this explanation chip-scale is the primary measure that realizes green energy conservation.
The CPU chip is the power resources of server, data center's computing power, data-handling capacity, in the past, people are the raising of single pursuit CPU chip arithmetic speed when design CPU chip, and improving CPU frequency is the absoluteness index that improves the CPU arithmetic speed.And need now balanced consider speed ability and power consumption, pursue the raising of computing power under the unit power consumption, rather than single computing power improves.The comparison of two technology paths has so just appearred.
The first improves the CPU dominant frequency to improve server computational power.For server is installed the more CPU of high primary frequency, higher complexity, to improve the computing power of server.Width of transistor and metal routing width, increase CPU data bus etc. in the pipeline series that the continuous CPU of increasing of this route meeting instruction is carried out, instruction issue number, the minimizing chip.These complexity, ultimate attainment design, the exactly work clock (dominant frequency) in order to promote CPU.But its result makes the power consumption of CPU be exponent increase, and it is considerably beyond the speed of CPU computing power increase, and both increases are extremely uneven.
It two is to increase CPU quantity to improve computing power.More CPU is installed or makes the more CPU core of CPU chip increase for server, improve the computing power of server, server cluster.The CPU that this route adopts is lower complexity, low dominant frequency often, and for example pipeline series is less, and the CPU data-bus width is less etc.The complexity that these have all significantly reduced the CPU circuit operates in below the lower dominant frequency it.Its result is the computing power linear increase with the increase of CPU quantity that makes server or server cluster, and power consumption also is linear increase, both balanced development that gathers way.
The below does more deep analysis to this, for the purpose of clear, supposes that the CPU design all is monokaryon under two kinds of technical schemes, and efficient is carried out in the instruction of ignoring simultaneously under the different CPU framework.
1) improves the CPU dominant frequency and improve computing power
The computing power of CPU chip with IPC(Instruction per Clock), namely the relation of every clock instruction actual figure, CPU dominant frequency can represent with formula 1:
CP = IPC * f （1）
CPThe computing power of (Computing Performance) expression CPU, IPCRepresent performed instruction number in the clock period, IPC is higher, and the CPU circuit is more complicated, uses CsThe scale complexity that represents the CPU circuit, it can be reflected as the logic gate element circuit quantity size of CPU circuit intuitively.The increase of CPU internal bus width also can increase the complexity of CPU circuit. fThe work clock frequency of CPU, the namely what is often called dominant frequency.Study again the power consumption of CPU.With reference to the energy consumption model of CMOS circuit, CPU power consumption and CPU operating voltage V, CPU circuit scale complexity Cs, CPU dominant frequency fRelations Among can represent with formula 2:
Pcpu＝ Cs * V * V * f （2）
PcpuBe the power consumption of CPU, it is proportional to the logic gate quantity of CPU circuit, namely is proportional to Cs, circuit load. PcpuBe proportional to the quadratic power of CPU operating voltage, be proportional to the CPU dominant frequency fUnder in same technique, with design, improve the CPU dominant frequency fAlso need synchronous raising V, so that formula 2 can be written as again:
Pcpu＝ Cs * V(f) * V(f) * f （3）
PcpuBe proportional to fCube relation.In fact, improve the dominant frequency of CPU f, design complexities improves, CsAlso be fDependent variable.
2) increase CPU quantity and improve computing power
The raising of CPU cluster computing power is that to increase group interior CPU quantity be main, and the computing power of CPU cluster is expressed as:
CPs = K * Mcpu * f （4）
CPsThe computing power of expression CPU cluster, K is one and adjusts coefficient, represents the dispatching efficiency of CPU cluster, McpuThe quantity of expression CPU.K is subjected to McpuThe impact, and K and McpuWith fBetween be independent variable, by formula 4 as seen, CPsWith fBetween just first power relation, i.e. linear relationship.Investigate the relation of CPU number of clusters and power consumption, CPU group's power consumption is the product of single CPU power consumption and CPU quantity, shows suc as formula 5:
Pcluster＝ Pcpu* Mcpu （5）
PclusterCPU group's power consumption, PcpuThe power consumption of single CPU, PclusterWith McpuLinear.
Reach equal computing power, can by improving the method for CPU dominant frequency, also can pass through to increase the method for CPU quantity.By above-mentioned analysis as can be known, improve dominant frequency and can make energy consumption be exponent increase, only make energy consumption be linear increase and increase CPU quantity, so, if can satisfy under the prerequisite of using, adopt the way that increases CPU quantity as far as possible, can very effectively reduce the energy consumption of server.
CPU pursues high primary frequency, can increase the pipeline stages (the CPU streamline such as Intel has surpassed 30 grades) that instruction is carried out, and can increase the scale complexity of CPU circuit design and the load number of demand motive (in the formula 2 Cs), thereby the increase that brings power consumption; CPU improves computing velocity also can widen the internal bus width, and this also can cause the increase of complexity and the power consumption of CPU circuit; The CPU circuit is for improving dominant frequency, and the live width of employing is near physics limit, and leakage current obviously increases, and has also brought electric energy loss.These have all reflected to continue to continue to use and improve dominant frequency, increase highway width, reduce the chip live width, and the old road of improving computing power has been not suitable for the demand for development when exhibition, walks to be at the end.
Can reach a conclusion by above-mentioned analysis: according to towards the different application field, the dominant frequency of choose reasonable CPU, highway width, CPU number of clusters, and cooperate the algorithm optimization of software are the correct methods that improves unit power consumption computing power.
The application facet of a server group of planes can be divided into high priority data and calculate preferential two classes.To reduce overall power consumption, to improve unit power consumption computing power as guiding, sum up the server CPU chip Top-layer Design Method standard that high priority data is used:
1) the control dominant frequency is below 1GHZ, because under current chip manufacturing technology condition, the CPU chip of the above dominant frequency of 1GHZ step can occur at technique, energy consumption and cost, and technique is take 90 nanometers as the boundary.
2) the CPU bus adopts 32, can satisfy the application of large section high priority data.Calculate preferential application for data, can the larger CPU of plug-in highway width.
3) CPU chip SOCization reduces the support to Peripheral Interface, reduces until cancellation peripheral matched chip strengthens the support to network communication.
4) adopt multinuclear, multithreading to calculate, suitably control pipeline series.
5) use for high priority data, or some special algorithm application, do not relate to the applied environment of Floating-point Computation, the cancellation floating point unit.Calculate preferential application for data, can plug-in GPU or CPU with floating point unit in order to accelerating, and carry out power managed.
Specification Design CPU chip out is called " cloud computing node CPU chip " according to this.Use this chip design little computing node circuit module out, except starting FLASH chip, memory chip, almost without any unnecessary peripheral chip and circuit module, power consumption control is at floor level, and volume is also very little.A plurality of little computing node modules cooperate power module, data exchange module, and assembling server out is called " microserver (Micro-Server) ".A large amount of microservers form cluster, can replace the General Server that the most of high priority data of data center is used, and are the primary and basic steps that realizes decrease data center total power consumption.
Instruct according to above-mentioned theory, one embodiment of the present of invention are, form little computing node with the CPU of 0.65GHZ dominant frequency, 32 MIPS frameworks, and power consumption is 50 watts.Comparison other is the HP server (Intel G850) of 2.9GHZ dominant frequency, 64 double-cores, X86 framework CPU, and its mainboard power consumption is greater than 200 watts, and both equal Adoption Network disks are the data storing mode.Because the super low-power consumption characteristic of microserver, originally 24 hours necessary air conditioner in machine room forced coolings of data center have become the air-conditioning use of common working environment.Microserver reduces energy consumption and then reduces air conditioning electricity, and only these two combine, and the power consumption of data center can reduce to original 25%.
