In 2004, the China Unix Server Market is a good year. Through continuous innovation and development, new hardware and software solutions have been launched in IBM-headed UNIX vendors. Therefore, users have more, stronger and better options in the UNIX field. In 2004, it was also a watershed in the China Unix server market. In such a watershed, the user has undoubtedly a bigger choice, but the difficulty of choice will undoubtedly increase. Therefore, users need to know more about their own needs and solutions, so that they are matched. The largest difference in the three major direction of the RISC processor Unix server is the attitude towards the RISC processor architecture. The UNIX server has always used the RISC processor. However, in 2004, various manufacturers have made different options: IBM continues to build a server in the form of a RISC processor and UNIX operating system, and launched a new generation of Power5 processors this year. A number of authoritative tests such as TPC and SPEC, using the new generation of P5 servers using the Power5 processor accounts top, especially P5 595, created TPC-C, more than 3 million transactions per minute. Amazing record. SUN has two development focus on RISC processors. First, high-end products will be launched in the next few years, and the other is to develop UltrasParc processors with Fujitsu. After the launch of its last generation of RISC processors, HP transferred its entire high-end product to the Intel platform. The RISC processor has several development directions in the future, one is to continue to improve the calculation speed, and the means mainly include increasing the number of integrated transistors, using new technologies such as copper chips, etc .; another direction is a multi-core design. IBM uses dual-core design on the Power processor, and "dual-core" is a balanced program. Because IBM's research shows that although more kernels can be integrated in a processor, but in a limited space, the more kernels mean that the performance of each kernel is getting worse. Therefore, it is necessary to achieve a balance, and improve performance is the development direction. One is to develop to the system chip (SOC). Power5 not only integrates the processor core, but also contains memory controllers, I / O devices, etc., other functions have also begun to be in the entire chip. This benefit is also very clear that the calculation and communication inside the system chip is far more efficient than external. The results obtained by P5 performance tests reflect that IBM has achieved a good condition in pursuit of balance. A variety of means to achieve a new breakthrough virtual technology can greatly improve the utilization efficiency of the server, effectively protect user investment, which has gradually been recognized by UNIX server users since 2004 and will become the focus of future development. IBM virtual engine can be implemented: re-allocation than the processor, allows idle calculation resources to automatically scheduling to busy application, and system effects can jump to a new height, so that the entire system utilizes efficiency to 70% to 80% level. Although the Linux operating system is not 100% UNIX, integrating Linux on UNIX Server has become the focus of user concern. The latest report shows that Linux's market share has doubled, and gradually begins to develop from web services and emails to a more critical application. Migrant manufacturers have a support plan for Linux, IBM can say that it is most prominent. The P5 Series server can run the Linux operating system at the same time or separately by its dynamic logical partition. Over the years, because UNIX servers are complicated, the flexibility of production and delivery is different from the flexibility of production and delivery than IA servers. However, in November 2004, after IBM launched the Authorized Product Customization Plan (AAP), it will make this situation greatly changed. AAP is an IBM and partner to meet the specific configuration requirements of the user, authorize and supervise the designated partners for product customization and delivery by IBM and supervise the designated partners.
