Description
Technical field
The present invention relates to computer communication field, be specifically related to a kind of large-scale control method of large server system fan more than 32 tunnel.
Background technology
Multipath server is accompanied by development of computer and develops.The invention original intention of computing machine is exactly in order to improve computing power, handles numerous and diverse data.But along with the development of technology, the progress in epoch is calculated and some fields such as financial sector in science, and the processing power of computing machine has been proposed more and more higher requirement.In the past few decades, can be described as the age that computer technology is constantly brought forth new ideas, new system architecture constantly occurs, from initial single cpu system, to multi-CPU system afterwards, new system architecture is constantly being explored by chip manufacturer, and new architecture is also constantly being studied by system applies manufacturer, various architectures and network interconnection technologies such as MPP, SMP, cluster have occurred.
Yet more and more huger system also means increasing power consumption, from tens watts of a single CPU computing machine, till now one may be up to the high-performance computer of several myriawatts, the power consumption of system has increased hundreds of times, thereby requires cooling system more and more efficiently.Meanwhile, energy problem has progressively developed into one of the most great problem of 21 century.How the various countries scientist is studying energy savings, and also more and more about the authentication of system energy consumption, the product energy consumption aspects that a lot of countries all require to come into the market need be by a series of understanding.About how reducing the energy consumption of system, become a more and more important problem.
Usually our computing machine all is to be in power-up state at operational process always, prepares deal with data at any time.Like this, can lossy a lot of power consumptions in the process of waiting for.Yet serious day by day along with energy problem had higher requirement to the energy-conservation of system, on this basis, proposes a kind ofly can dynamically control rotation speed of the fan according to system loading, suitably saves the power consumption of system, just seems very necessary.
Domestic server system seldom has to surpass 32 tunnel big system at present, so all be single node control in system fan control, the fan control that the present invention mentions is meant the single node monitoring control of whole big system in addition.
Summary of the invention
The concentrated controling management method that the purpose of this invention is to provide a kind of large server radiator fan.
The objective of the invention is to realize in the following manner, temperature by each node of monitoring management module real-time monitoring system and Switching Module, the rotating speed of fan is detected and controlled to fan grouping management in the fan disk by the SMBUS bus, best heat radiation of the system that reaches and purpose of energy saving, system architecture comprises: the hot plug control module, fan control module, time delay module, fan disk Head switches and failure indication module, the monitoring management unit module, wherein:
When the hot plug control module is responsible for the hot-plug fan dish, the protection of power supply and signal;
Fan control module is responsible for the detecting of rotation speed of the fan and the control of rotation speed of the fan;
Fan disk Head switches and failure indication module are responsible for the alarm of the switch and the fault fan of fan disk;
The monitoring management unit module reads the temperature of all modules and the monitoring management of all fans by System Management Bus;
Concrete steps are as follows:
After the total system all devices installs, start, each several part enters normal duty, hot plug partial bus switch and power unit switch closure, power supply from backboard directly to fan control module, fan control module connects fan governor, 5 fans of each fan governor control, corresponding with it is that per 10 fans are formed a fan disk, per 5 fans are one group, whenever open behind one group of fan by time delay module time-delay 150ms, open second group of fan again, reduce of the influence of the surge of start all fans generations of moment with this to system, start simultaneously by original 80 fans and to be reduced to 40 fans and to start simultaneously, after fan is opened, the monitoring management unit module also carries out monitoring management by SMBUS to fan, when the monitoring management unit module detects that fan breaks down in each fan disk, can notify fan governor in the fan control module by SMBUS, fan governor receives that the alarm lamp that can light the front after the information notifies the keeper, the keeper opens switch afterwards, carrying out fan disk changes, in the moment of opening switch and Closing Switch, the switch of hot plug part is open and close thereupon also, also notify simultaneously the monitoring management unit module, the monitoring management module also shields the SMBUS of this fan disk, in the process of hot swap, can not impact backplane and system.
The invention has the beneficial effects as follows:
A. energy-saving design and fan divide the batch initiation design.This system adopts monitoring total system in real time, control the speed of relevant position fan according to the temperature of the diverse location that monitors, in other words, the rotating speed of each fan all is a dynamic adjustments, their rotating speed is designed just satisfies the system radiating needs, thereby has reached purpose of energy saving.Because this system is big system, tens fans are opened has very big electric current in a flash, so this control system adopts to get up in two batches, the demand to electric current just can reduce by half like this! Influence to system also reduces.
B. operate simple and easy, charged for replacement fan at any time.Most of servers are because be no more than 8 the tunnel, fan is directly controlled by mainboard, the hot plug and the energy-saving design that do not possess fan, when fan breaks down, can only turn off the system conversion fan, the support hot plug that has, but without any operation circuit, the moment that so not only plugs fan disk can produce very big surge, backboard and system is caused very big injury, but also may cut off the bus communication between fan governor and the system.Adopt the method for native system can avoid the problems referred to above, this system is a unit with the fan disk, and any one fan breaks down in the fan disk if detect, and makes whole fan disk is changed.Application scalability that in addition should invention is very strong, and it is a unit with 10 fans, makes fan disk, and system is big more, and the quantity that increases fan disk gets final product, applicable to 32 the tunnel, and 64 the tunnel even higher system.
