Background technology

In the past decade, infotech is develop rapidly, and for example the effect at the computer network center of server farm and group of server has become for our society and become more and more important.Server farm provides effective data storage and data allocations ability, and described data allocations ability is supported the information infrastructure in the whole world, and described facility has been arranged our life style and daily commercial activity.

Server farm is the computing machine that a group or a group are served as server, and it is contained in single position together.For example, the Web server field can be the Web place with an above server, also can be to utilize a plurality of servers that the ISP of web hosting service service is provided.In commercial network, server farm or group can realize such service, as provide concentrated access control, file access, printing to share and the backup of workstation user.

In order to utilize the effect of scale economy, in the past decade, the computing machine number of lodging in the server farm constantly increases.This caused increasing day by day to the demand in the space of capacity network main computer unit and the demand of integrating (consolidation) their spaces of living in.The place that is known as place, same place has occurred to satisfy this market demands, and wherein a plurality of network computers find boarding space (home).Usually hire out the space that is used for described computing machine in this place.The calculating of rent can be based on absorb space, power consumption and the bandwidth that takies the Computer Processing in described space.Because the mutual relationship between these factors, maximize the density and the operational efficiency of computing machine simultaneously at given website, this helps place, same place and Computer Service provider usually simultaneously.By being increased in the density of holding computing machine in the given area, when needing less space for given quantity Calculation machine, the service provider can benefit from it; Owing to can roll up the final available bandwidth relevant with free space, therefore place, same place also can be benefited.

Other distant interests derive from saves the main frame occupation space.In many cases, it is economically viable withdrawing from other out-of-date main frame in advance, because the space hold expense of described out-of-date main frame is lower, thereby adjusts their continuous services in a period of time.On the other hand, when the high-end computer in preferred the reservation server, be apparent that, under the condition that does not influence its performance, saved expense by the size that minimizes these computing machines.Like this, need a kind of computer system that is suitable for realizing these advantages.

Usually, in the place that a large amount of computing machines is connected to network, be stacked in the frame computing machine and row or unit cell arrangement to repeat.For keep in repair, upgrading hardware, load software, stube cable, connection or powered-down etc., the contact computation machine is inevitable.By reducing attaching space as far as possible, can increase the density of computer system, described computer system is set on the given floor area of building at a place.Therefore, this need reduce irrelevant attaching space, and still keeps using (or being greater than or less than standard size) frame relatively cheap, standard.

In present market, the standard rack size of widespread use is that about 19 inches wide, 30 inches are dark and 74 inches high.In at least one place, same place, these frames are embarked on journey arranges and has about 10-30 unit, and has on each side of frame and contact.On the two sides of being expert at contact channels is set.On a plurality of frames, place the computing machine that is installed in the heaviness on the slider, by the attached described slider of the mounting hole on the front and back that is arranged on frame.No matter computer cabinet design (or no frame, wherein just computing machine is installed on the open bracket, and does not cover its parts), with and be installed to the mode of frame, can be from the data equipment the positive access computer.These visit mainboard I/O equipment, other I/O equipment, power lead etc. from the back side usually.For this back one design proposal, it not only causes the inefficiency of required attaching space amount, also causes and the necessary management frequent inefficiency relevant to the maintenance on computing machine two sides.Therefore, need a kind of computing machine that can be used in the network settings, it can be from single face contact and full maintenance.

Since the increase of the number of computers in the server farm, two inconsistent factors contribute: the consumption of floor area and heat radiation/ventilating management.Increase the computing machine number and do not increase density of computers in given server farm, meaning need more space.Because especially in the high city of the density of population, therefore house property cost continuous rise wishes the space that maximum using is given consumingly.And, in the facility of some existing server farm, there is not more free space to be used for expanding development.In this case, must bear the expense of newly opening server farm in order just to expand.

Optionally, can attempt increasing the number of computers that is contained in the given space.In order significantly to increase the density of computers in the given space, a common scheme is the size of dwindling each each independent computing machine in the frame.Another possibility is the interval that reduces to be equipped with between the frame that computing machine piles up.

Yet along with the increase of density of computers, the problem index relevant with heat radiation increases.A main cause of electronic component fault is exactly overheated.For example the high performance electronic element of CPU produces a large amount of heats.And along with the increase of computation requirement, processor of future generation can produce more heats.Produced further requirement like this to efficiently radiates heat.In order to make computing machine continue normal operation, just must provide suitable heat radiation approach.Because each computing machine comprises the electronic units of thousands of heatings, when increasing density of computers, must solve the difficult problem of the cooling mechanism that provides suitable, so that from single computer node and whole group, remove heat.

With respect to the other electron component in the computing unit, power supply also produces a large amount of heats, with the traditional structure in power distribution each computing unit in computer rack, there are many defectives in the heat levels in being controlled at single computer node level and group level.Each layer that power supply is placed in the computer rack of independent computing unit therein all produces a large amount of heats.In order to cool off power supply, independent fan is set usually to remove power supply heat on every side.Power supply fan self will produce extra heat.Because hot-air is because the rising of its buoyancy, the heat that power supply in computer rack lower layer or groove produces must by or around the computing unit that is positioned at above it, and also having too much caloric requirement, these computing units self are removed, because their its own power source and electronic component also produce heat.

Can provide significant advantage aspect two of the efficient of the independent computing unit of computer system each in frame of multicomputer platform and the efficient of computing system as a whole, described system redistributes power supply in computer rack, and promotes each the independent computing unit from be placed on computer rack to remove heat.Because to control of generating heat and the ability of cooling off a large amount of computing machines is the major limitation that increases the ability of density of computers in the given area, therefore the computer rack that obtains to have the heating control structure of improvement can overcome this problem, and allows the computer operator to place more multicomputer frame in given space.In addition, when power supply is removed from single computer node, can use additional space to hold miscellaneous equipment or parts, thereby improve the global density of server farm.

Therefore, the higher density of computers of a kind of permission, and improve the technical scheme of heat radiation to computer set (for example improve that heat is ventilated and to the cooling of machine element) simultaneously, bring remarkable economic efficiency can for the operation of server farm.
