Blade server case

Abstract

A cabinet of blade server is prepared as setting cabinet height to be 7U, setting medium plate in cabinet and arranging ten connectors for containing 10 pieces of IU calculation blades on medium plate in parallel way, arranging medium plate at middle part of cabinet as its one side being space to contain 10 pieces of IU calculation blades and another end being space to place modules.

Description

Technical field [0001] The invention relates to a server chassis, in particular to a blade server chassis. Background technique [0002] At present, the height of the chassis adopted by blade servers is generally about 7U, while the number of blade servers in a single chassis is concentrated between 12 and 16. The largest 16 blades are Hewlett-Packard’s ProLiant 30p or 35p, which uses a 3U design. Two blades of this height are stacked on top of each other and then inserted into a 6U chassis with 8 slots instead of the 16 standard. Full-height slots. Therefore, 16 blades are not a standard configuration in a chassis. [0003] As for the products that can accommodate 14 blades in a chassis, mainly the BladeCenter series of International Business Machines Corporation (hereinafter referred to as IBM). In its blade design process, IBM has always adhered to an important basic principle: The computing density of blade servers is twice that of traditional 1U servers. In order to achieve ...

Problems solved by technology

The following two problems will arise when using a low-power processor: 1. At the same time, the highest performance of the low-power processor launched is one or two grades lower than the corresponding ordinary version of the highest performance processor; 2. At the same time, The price of low-power processors with the same frequency and performance is about 1.5 to 1.8 times that of ordinary processors

This can ensure that the blade system can effectively cool the system in the case of low-power processors, but it increases the complexity of the system design

[0005] The third point, according to the blade server problem reported on IBM's official website, it is found that when 14 blades are fully loaded, the power module cannot provide enough redundant power

With the idea of ​​multi-core design, without reducing the performance of each processor core, the processing core and L1, L2Cache will be doubled, and the number of transistors will increase exponentially, which will inevitably lead to a rapid increase in power consumption

On the other hand, although the power consumption can be reduced with the improvement of the process, with the deep submicron (below 90nm) process, the static power consumption caused by the gate leakage current has become an increasingly serious problem affecting power consumption. The problem

And the situation will get worse as the process shrinks further

All of these factors lead to a tendency for individual CPU power consumption to increase

Therefore, too large blade density is difficult to support the growth rate of CPU power consumption in the future
