Description

A kind of blade server case

Technical field

The present invention relates to a kind of machine box for server, particularly relate to a kind of blade server case.

Background technology

The cabinet height that the current blade server adopts is to be generally about 7U, and unit case blade server number concentrates between 12～16.ProLiant 30p or 35p that 16 maximum blades are Hewlett-Packard, what it adopted is the design of 3U, two like this blades of height stack up and down, insert jointly again in the cabinet of 6U of 8 groove positions, rather than the groove position of 16 standard overall heights.So 16 blades are not standard configurations at a cabinet.

For the product that can hold 14 blades in the cabinet, mainly be the BladeCenter series of International Business Machine Corporation (IBM) (hereinafter to be referred as IBM).IBM has observed an important cardinal rule all the time in its insert design process: the blade server bulk density is to reach 2 times of traditional 1U server bulk density.In order to reach this design object, the IBM blade adopts original and different vector cooling scheme aspect heat radiation; Done the design of compromise in the CPU power consumption.First point, IBM adopts low power processor to solve CPU heat problems of too on blade processor is selected.The power consumption of the general processor of selecting is between 50～65W.Adopt low power processor following two problems can occur: 1, the same time, the low power processor peak performance of release is than low one to two class of processor of corresponding plaintext peak performance; 2, the same time, same frequency approximately is being 1.5～1.8 times of ordinary processor in price with the low power processor of performance.

Second point, IBM adopts the turbine type air exhauster of concentrating " central air conditioner formula " and the heat dissipation problem that vector air channel heat dissipation design solves 14 blades.This point can guarantee under the situation of blade system at low power processor, effective cooling system, but increased the complicacy of system design.

Thirdly, according to the blade server problem that IBM official website reports out, find that power module can not provide enough redundant powers under the situation of 14 blade full loads.And advise that pulling out 2 nodes just can solve, and this shows that IBM is to still existing the excessive problem of density in the design of its 14 slots.To sum up, we as can be seen the 7U14 sheet be not the optimal design of blade.

And in design, had better not adopt odd number, and because like this under the situation of design of the Redundancy Design of carrying out software, load balancing or two-node cluster hot backup, have the single blade node list that falls, preferably adopt 2 integer power power, perhaps 2 integral multiple.So 13 neither a desirable selection.

For 12, owing to be the integral multiple of 2 power power, the application model of software is favourable to future, sums up in addition on IBM BladeCenter design error basis, so be relatively reasonable feasible and a selection that bulk density is also bigger.If adopt the 7U cabinet, and cabinet density is 12 blades, each blade is under the situation of 2 CPU, the bulk density of whole standard 42U rack is 6 * 12 * 2=144,84 CPU density than traditional 42U have improved 71.4%, if each blade node can provide and the suitable performance of standard 1U node, the lifting of so this performance still is appreciable.Though what be noted that especially that XtremeBlade blade that Korea S Appro releases adopts is 12, the width of its cabinet is not an employing standard 19 " width, but 24 ".Its blade system cabinet size is that (H) * 36 " (D), the width of its each blade server also is 1U to 24 " (W) * 12.25 ".Though in summary it can be seen 12 schemes the rationality of certain existence is arranged, consider and the importance of the compatibility of whole server industrial system standard, do not advise adopting 12 solution.

The width of " standard cabinet in, the blade server system cabinet is general to adopt 17.5 " because 19 is so if insert 12 blades, the width of each blade server is 0.83U so.Because this thickness is not the industrial size of standard, thus for CPU, heat radiator, internal memory or the like at chip size, the relative 0.83U in particularly Gao Du design, and heat radiation aspect highly is incompatible.Incompatiblely not only can improve design difficulty, in mechanical dimension and heat radiation process, bring very big design risk also can for us, even the possibility of design failure is arranged.

In addition, from the CPU developing history, be main method by improving processor frequencies merely, the epoch of improving processor performance are over and done with.From the historical statistics data, when processor host frequency was more and more higher, " acceleration " of frequency upgrading but slowing down gradually.Along with the thought of multinuclear design, under the prerequisite that does not reduce each processor core performance, meeting increase process nuclear and L1, L2Cache at double, transistor size is doubled and redoubled, and will inevitably cause the rapid lifting of power consumption.On the other hand, though power consumption can decrease along with the improvement of technology, along with deep-submicron (90nm is following) technology, the quiescent dissipation that is caused by grid leakage current more and more becomes a problem that is on the rise that influences power consumption.And along with further the dwindling of technology, this situation will worsen more.All of these factors taken together all can cause the single cpu power consumption that the trend of increase is arranged.Therefore excessive blade density is difficult to support the growth rate of CPU power consumption from now on.

Summary of the invention

The purpose of this invention is to provide a kind of blade server case, can be good at guaranteeing compatibility in design, also help reducing simultaneously component costs with the 1U industrial standard based on the 7U10 sheet.

Technical scheme of the present invention is achieved in that

A kind of blade server case, described cabinet height is 7U, cabinet is provided with middle plate, is arranged side by side 10 on the described middle plate and holds the connectors that 10 1U calculate blades.

Plate is positioned at the middle part of cabinet in described, and middle plate one side is to hold the space that 10 1U calculate blade, and opposite side is the space of placement module.

The space of described placement module comprises space, the space that is used for the placement management module that is used to place Switching Module, the space that is used to place the space of IO expansion module and is used to place power module.

The described space that is used to place Switching Module is two-layer, and ground floor is for placing the space of infinite bandwidth switch, and the centre of the second layer is for placing the space of 2 gigabit switch, and respectively there is the space of a placement management module on second layer both sides.

Beneficial effect of the present invention is as follows:

1, adopts the 19 " racks of normal width; select 7U10 sheet cabinet scheme of the present invention for use; the width of each blade is standard 1U (1.75 ") width so, like this, a lot of parts can both adopt the design part of standard 1U, can be good on the one hand guaranteeing compatibility in design, help reducing component costs on the other hand with present 1U industrial standard;

2,,, have bigger directive significance for carrying out the cabinet exploitation like this so can from the design of 1U cabinet, obtain reference for calculating the design of blade air duct radiation because manufacturer server has the experience that designs for standard 1U, 2U cabinet for many years;

3, owing to used calculating blade in the blade server case of the present invention adopts the 1U width, processor and heat radiator that so common 1U rack-mount server can be suitable for, blade server to the 1U width also guarantees to be suitable in mechanical dimension, and heat radiation can be relatively easy simultaneously.So used calculating blade can adopt the main flow processor among the present invention, not the processor that must use low-power consumption, therefore, can reduce the CPU cost greatly, obtain good cost performance, thereby reduce whole blade cost of products, have more the market competitiveness.Simultaneously, adopt the design proposal of 7U10 sheet of the present invention, make used calculating blade among the present invention can either support the CPU of high-performance, high power consumption, also can support the CPU of low-power consumption, therefore have CPU selection scheme flexibly.

4,, can be good at realizing 4 road and 8 road SMP (SymmetricalMulti-Processing, symmetrical multiprocessing technology) for 10 frameworks of 7U.For 4 road SMP, each calculating blade accounts for the words of 2 groove positions and can support 5 to calculate blades; For 8 road SMP, each calculates blade and accounts for 5 groove positions, can support 2 to calculate blade.Here want Special attention will be given to once, account for the 5U SPATIAL CALCULATION according to present 8 road SMP A950, the 42U rack is supported 8 at most, and the bulk density of a rack is 8 * 8=64 so.And adopt the accessible bulk density of blade type 8 road SMP solutions is 2 * 8 * 6=96, and bulk density totally doubles than traditional rack.

5,7U10 sheet blade server case of the present invention helps reducing system cost, simplifies heat dissipation design.
