Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1 to Fig. 6:
Power-supply system is responsible for providing power supply to each module in the whole blade system and cabinet, carries out electric sequence control and power and distributes; Following electric sequential control and Power Recovery; Power supply redundancy control, power module fault analysis, warning.Power-supply system adopts the mode of operation of two kinds of voltages that power-supply system integral body is divided into two working fields: power management territory (Power Management Domain:PMD) and power supply task domain (PowerTask Domain:PTD).
The order power-on and power-off system of a kind of blade type server system of the present invention comprises: fan (FAN), blade (Blade), switch (SW), IOE expansion module, and its special character is also to comprise:
Administration module (MM) adopts connection of " centralization " formula and control power-supply system, IOE expansion module, switch, blade, fan;
Power-supply system (PS) is used for power-on and power-off sequential control, power distribution and recovery, power supply redundancy control, fault analysis and warning, is divided into: power management territory and task domain;
Wherein, described power management territory is the power supply of originate mode ADMINISTRATION SUBSYSTEM, adopt the 12v Standby power unit of power module, as long as there is the AC input in power module, whole PMD just has power output, the corresponding management subsystem is the energy operate as normal just, the not managed module controls that powers on here; The power supply task domain is powered for each module is under the normal mode of operation, for example parts such as the CPU of blade server, internal memory, hard disk just adopt the power supply of PTD power supply, these systematic unities come from the 12v of power module, and power-on and power-off simultaneously are subjected to ADMINISTRATION SUBSYSTEM control and the management among the PMD.For PTD part power-supply system is the control model of being carried out " functionalization " by administration module.
Described administration module powers on to the power supply task domain and asks to adopt the pattern of " applying for-examine ", " notice-affirmation " adopted in following electricity request, other module is if make change to the PTD state, particularly for the request that powers on, must at first file an application to administration module, after the process administration module is examined, take corresponding operating, what power on employing is " applying for-examine " pattern, and for electric control down, because electricity does not need new power resource down, so what adopt is " notice-affirmation " pattern, implication is exactly that the one side administration module can notify blade and other each module need descend electric control, also can send the following electricity of each module transmission of blade and other in addition and be notified to administration module, and decide down the affirmation that electricity does not wait administration module in its sole discretion, such as situation very urgent in heat radiation, blade server can be decided down the electricity operation in its sole discretion.
The RS485 bus is adopted in being connected of described administration module and blade, adopt the I2C bus with power-supply system, IOE expansion module, switch, being connected of fan, the power-supply system management realizes by various power management command, and power management command is transmitted on the various buses of management system with the form of Frame, System Management Bus embodies central controlled thought, be that various device all is connected with administration module by industrial bus, do not connect each other.
Described blade server system can be supported hot plug operations, and for the parts of not supporting hot plug, administration module blade server system at once carries out electric treatment under the system.
The parts of described support hot plug are: blade, administration module, gigabit switch, Infiniband switch, the redundant power module of band, in addition, no longer include any hot plug parts, parts for hot plug, there is administration module to control in proper order according to normal power-on and power-off, in a single day pulled out for the parts of not supporting hot plug, administration module blade server system at once descends electric treatment, promptly work as the IOE module, or pull out too much no longer redundant power module and just descend electric treatment by administration module blade server system at once.
According to the division of blade server system state, electric sequence is divided into two kinds: first kind, and the electric sequence of the whole blade system that begins from resting state; Second kind, can the hot plug module electric sequence the single of run mode.The blade server system push button function that powers on is defined as follows: blade server system is always gone up eletric button: function is by the administration module software arrangements, and cabinet, fan etc. only power under the default situation; Eletric button on the blade: only for specifying blade to power on, the not operation of total button can't power on.The electric sequence of whole blade server system is the important assurance that security of system can safe and reliable operation, also is the process that blade server system is changed from the resting state to the run mode.The initial necessary condition that blade server system powers on is: have at least a power module to be present in the blade system; Having at least an administration module to be present in needs at least one blade server module online in the blade system.Starting condition: referring to blade server system is starting condition in the situation that does not insert the AC input, inserts the electric sequence of the module of combination in any in this case.State input: the blade server system request of powering on, can be from the blade server system request button that powers on, the also request of powering on of the administration interface that can provide from administration module.The basic thought that powers on is: and administration module powers on-fan powers on-switch powers on-and blade and IOE power on simultaneously.
A kind of order power-on and power-off method of blade server system, concrete steps:
I, system power on from stationary state (original state):
A:AC imports access, power module output 12V Standby, and the ADMINISTRATION SUBSYSTEM of administration module and online other module is started working, and carries out the total system initialization operation;
B: administration module and power module carry out communication, judge online power module power amount, state and quantity, and administration module calculates the whole useful power output that power module can provide;
C: whether power module work is normal:
C1: when working properly, the waiting system request of powering on,
C2: work when undesired, stop power up at once and report the corresponding system mistake;
D: whether system's request of powering on, at first detecting has blade online if being arranged:
D1: there is blade online, carries out the request of powering on,
D2: do not have blade online, stop the request of powering on, send alarm simultaneously;
E: start blower module and whether satisfy the minimalist configuration requirement (minimalist configuration requires and can determine the air channel according to the Present-Detect pin of blade, thereby determines the fan minimalist configuration) that starts:
E1: satisfy, the full speed running fan,
E2: do not satisfy, stop power up at once and report the corresponding system mistake;
F: check whether the fan operation is normal:
F1: operation is normal, detects all at wire module,
F2: it is undesired to move, and stops power up at once and reports the corresponding system mistake;
G: detect the whether online or request of blade and power on:
G1: have online or the request of powering on, judge whether switch is online,
G2: do not have the online or request of blade to power on, reduce rotation speed of the fan and wait for that blade powers on;
Whether h: it is online to detect switch:
H1: online, judge whether the IOE module is online,
H2: not online, switch is not carried out the initialization power up;
I: judge whether the IOE module is online:
I1: online, give do not power in the minimum blade server of groove position code power on, give IOE associated socket power on (guaranteeing that main frame and PCI-E interface power on synchronously) simultaneously,
I2: not online, power on for the middle minimum blade server of groove position code that do not power on;
J: detection also has or not the blade request to power on:
J1: have, continue to carry out operation,
J2: do not have, jump to the l step;
K: whenever gone up a blade (, so just comprising corresponding PCI-E slot), distributed actual distribution condition to judge whether to allow next blade to power on according to current power if IOE is arranged:
K1: allow, jump to the i step, continue as next groove position blade and power on,
K2: do not allow, reporting an error stops powering on operation;
L: adjust rotation speed of the fan according to system operation situation, the entire system initialization powers on and finishes.
When powering on for first blade, do not make power calculation, be to be based upon a power module can support under the hypothesis prerequisite of at least one blade server and every other supplementary module, if being false, this hypothesis need before first blade powers on, calculate, calculating was divided into for two steps for power division, the first step is the power predistribution before powering on, in this step functional module is that the power demand from the maximum full configuration situation of the storage in fixing Flash is sent to administration module examining, and what illustrate here is that full configuration is not represented actual disposition.So finished the application that also will carry out the power actual allocated after the BIOS self check and give administration module on blade, this is the second step power distribution result.Such as according to different configurations, can insert 8 internal memories, 4 internal memories, 2 internal memories or two or a hard disk in the blade, even the two CPU differences of list in the future, for power consumption notable difference is arranged still.This two strategies that go on foot power distribution can guarantee that blade can not power on (maximum full configuration power consumption) by mistake on the one hand, can guarantee the accuracy that power consumption is used on the one hand in addition, are that the power consumption distribution is more reasonable.
Following electric process is relative with power up, also divides two kinds: first kind, and the following electricity order of the whole blade system that begins from run mode, second kind, electricity order under the individual module of run mode.
The whole initial electricity order down of blade system, starting condition: be meant that working as blade system is starting condition (having a blade at least in operation) in the situation of operation, state input: electricity request under the system, can be under the system power supply button request, the also request of powering on of the administration interface that can provide from administration module, the basic thought of following electricity is: blade and IOE stop to export 12v voltage with electricity-power module under electricity-fan under electricity-switch at present and get back to resting state.
II, system descend electric concrete steps from running status (original state):
M: blade system is in run mode;
N: receive electricity request under the system;
O: judged whether that the IOE module is online:
O1: have, administration module electric requirement under the corresponding PCI-E slot broadcasting of blade server with the IOE module,
O2: do not have, administration module is to blade server broadcasting electric requirement down;
P: wait for that electricity is confirmed under all blades and the IOE respective grooves position;
Q: the notice switch down;
R: wait for switch electricity affirmation down;
S: the notice fan down;
T: wait for fan electricity affirmation down;
U: the notice power module stops 12v output, and following electric process is finished.
When blade server was in run mode, independent module can be carried out hot plug operations, so also there is certain electrifying timing sequence problem.Module that can hot plug has: blade, switch, administration module, consider separately for redundant power.Owing to all be operated among the PTD, can adopt identical strategy to power on for blade and switch, unified HPPM (the Hot Plug﹠amp that adopts here; Play Module) expression.And administration module is owing to being operated among the PMD, so the situation when designing the PMD output power greater than two administration modules just can directly power on.
III, at the module electric sequence of blade server system hot pluggable condition, carry out following steps:
Insert hot plug module HPPM in the blade server system of a, operation;
Whether b, administration module rated output distribute remaining sum, allow hot plug module HPPM to power on,
B1, be, carry out step c,
B2, not, power-supply system provides system's warning, and halt system powers on simultaneously;
C, administration module judge whether that blade is online,
C1, be, carry out steps d,
C2, not, power module powers on to switch module;
D, administration module judge whether to contain the IOE module,
D1, be, power-supply system powers on for the blade server that sends the request of powering on, and power module powers on for IOE module associated socket simultaneously, and carries out step e,
D2, not, power-supply system powers on for the blade server that sends the request of powering on, and carries out step e;
E, hot plug module HPPM power on and finish;
F, administration module are adjusted each rotation speed of the fan according to the final ruuning situation of system.
The strategy that powers on adopts the pattern of " applying for-examine ", each module at first provides the power number of self-demand to administration module, and administration module is examining according to present power remaining sum, if the power remaining sum is not enough, then do not power on and examine, otherwise the approval that powers on.For obtaining of the authority that powers on, adopt the mechanism of the authority acquiring that once powers on.Such way can guarantee: the first, can not cause blade to miss the operation that powers on, all need once new application because power at every turn.The second, in a single day apply for successfully, under electric down situation (even restarting), distribute, also need not apply for once more, reduce the communication number of times because change power.
Basic thought at electricity under the module of run mode is: following electric module files an application-and electric under the administration module approval-module, and send acknowledge message-administration module and carry out Power Recovery, electricity is finished under the module.Here it should be noted that, when the neither one administration module is online, also to support down the electricity operation, if promptly continuous three the transmission requests of electric module can not be given the ratification down, just think and just descend the electricity operation by local management system immediately by administration module not online (considering whether will increase the online position of administration module).When electric instantly module is last blade server, carry out electric step under the system, close total system.What mainly adopt in the electric strategy down is " notice-affirmation " pattern, is different from the strategy that powers on, and mainly is that rated output reclaims problem.Owing to adopt the power module design proposal of full customization, need to specify the line related function, power interface and relevant communications protocol parts for power module for this reason.Power supply function definition: peak power output 4800W; Supporting N+1 power supply redundancy pattern, unless a power supply is only arranged, is redundant configuration otherwise a power module is necessarily arranged, and can finish redundant the switching automatically when power supply breaks down; Correlation behavior information can be provided, comprise output voltage values, power module temperature value, power module peak power output, power module power operating position, power module health and fitness information, promptly redundant situation; Power interface bus: I2C bus; Power supply communications protocol: TBD.
IV, in proper order electric under the module of blade server system hot pluggable condition, carry out following steps:
G, following electric module are filed an application;
H, administration module approval;
Electricity and send acknowledge message under i, the module;
J, administration module control power-supply system are carried out Power Recovery;
Electricity is finished under k, the module.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present invention.
