Patented technology scans domestic and foreign blade server market

I. Industry and standards Development


　　


2002, Blade Server entered China. At present, five foreign manufacturers IBM, HP, Sun, AMD, Dell still occupy the domestic blade server market about 80%. But in recent years, the Wave, founder, Dawn, the Great Wall, Pao and other domestic enterprises have begun to promote their own design, manufacture of blade server, market development speed.


　　


because the price is more expensive, blade server early customers mainly focus on the telecommunications, financial sector, the main purpose is the data center. In fact, the blade server is widely used to serve as data support blades, medical imaging blades, video game blades, Virtual PC blades, network blades, management blades, storage blades, synthetic 3D effects of video processing blades, enterprise information system blades, extended I/O blades, Fibre Channel san blades, etc. Many customers need a large number of blades server for data processing, many large enterprises need thousands of blades server. In short, with the increasing popularity of blade servers, the market demand will increase by more than 10 times in the next few years, and gradually replace the traditional server.


　　

The development of
Blade server is inseparable from the strong standardization work. Blade server began with a high-performance bus standard developed by Ziatech Company in 1994--compact PCI standard? Compact PCI, abbreviation CPCI standard? Later, PICMG (PCI Industrial Computer manufacturer's Group) began to lead the development of CPCI standards. Founded in 1994, PICMG is a technical alliance of more than 450 enterprises. The purpose of its establishment is to improve and promote CPCI, and to manage and maintain some public intellectual property rights. At present, PICMG has developed more than 20 versions of technical standards on 49 types of products and services related to blade servers, including CPCI, ADVANCEDTCA, CPCI Express, Advanced Mezzanine card, etc. These standards define a computer system based on backplane connections and I/O systems, including its physical specifications, electrical characteristics, communication bus, reliability, manageability, and so on.


　　


at present, only Hewlett-Packard company claimed to comply fully with the CPCI standard, other blade server manufacturers mainly in the bus, interface standards to follow the CPCI, in the blade size, and many other aspects did not follow the CPCI standard. Therefore, from the current situation, the subsequent version of the CPCI standard may be difficult to be fully accepted by most manufacturers.





second, domestic and foreign patent deployment situation


　　


foreign authorized Blade server patents are mainly distributed in the United States. For example, the US7237130 document relates to a blade server operation management method and system. The US7209347 number and US7193847 refer to a blade server system. The US7143279 document relates to a new technology for dynamic BIOS execution and synchronization of blade servers. The US7093048 document relates to a system and method for reducing the voltage inrush current of a blade server.


　　


the United States Patent and Trademark Office of the Open Blade server patent applications are also many. For example, the US20070115627 document relates to a blade server bus. The US20070094531 document relates to an extensible storage device for a blade server system. The US20070093092 document relates to a ground physical design of a blade server and its ascending structure. The US20070083774 document relates to a power supply security mechanism for blade servers after a blade management controller crashes.


　　


In addition, the US20060218326 document relates to a blade server system and its management methods. The literature of US20060193112 and US20050157461 relates to a frame for computing a blade server carrying a network switch. The US20060190484 document relates to a system and method for user redistribution of blade servers. The US20060161972 document relates to a system and method for licensing management in Blade server systems. The US20060140211 document relates to a blade server system with management bus and its management method. The US20060026325 document relates to a method for automatically allocating communication port addresses and its blade server system.


　　


domestic patent applications mainly from IBM, Dell and other foreign enterprises. However, China's Taiwan's quanta, Britain and other companies in China's state intellectual Property Office open the relevant application amount slightly higher than the total number of U.S. enterprises. Mainland enterprises such as the Wave, Huawei, founder, Shuguang and other companies have a number of patent applications. In many other areas of technology, enterprise patent applications often do not account for the majority. However, the search shows that there are very few patent applications in the field of Blade server in our research institutes and individuals. Looking from the content, the blade server patent application mainly distributes in the following technical domain:


　　


First, Blade server. For example, 200410045938. Document 1th relates to a blade server that includes a System management unit for outputting control signals, a blade server that communicates with the System Management unit based on a signal line, and an isolating circuit in which the signal line of the blade server outputs a communication signal through the isolation circuit. 200610061485. Document No. 0 relates to a blade server, which includes a unified Exchange interface for data interchange, multiple processor blades, each processor blade comprising a switching interface that matches a unified switching interface, and a unified switching interface; One or more peripheral blades, Each peripheral blade includes a switching interface that matches the unified switching interface, is connected to a unified exchange interface, and a backplane that connects the processor blade with the peripheral blade.
