Today's server market, the X86 instruction set based IA architecture (PC) server has become an absolute mainstream, and the recent development of the future server technology has or will be applied to the PC server.
From the domestic market, major server manufacturers are constantly accelerating the speed of new products. While continuously improve the performance of PC servers, the latest information technology is more and more widely served in social life. The rapid development of the national economy is also reflected in the increasing growth of the needs of the server product products and the increasing application level.
The development of Internet technology has further promoted people's demand for network nodes. As the main network bandwidth is doubled, the amount of data that everyone has doubled every year. Today's PC servers face a wide variety of user needs, in addition to traditional tasks such as documents, email and print services, the database query, voice, video applications and other multimedia new tasks.
In the face of real-time enterprise management applications based on database, ERP, CRM, SCM ..., facing the design, simulation, Pattern recognition, data encryption, identity authentication, etc., traditional X86 architectural 32-bit addressing capabilities have begun to become a key bottleneck that hinders server development.
Before the AMD is launched, the AMD64 technology compatible with 32-bit and 64-bit calculations, many users are still hesitant to adopt a dedicated incompatible 64-bit computing system because of the existing 32-bit system, although 64-bit server performance is more Strong, more advanced, extended space is also broad, but it is incompatible will bring a lot of problems: users must give up investment in the past 32 platforms, must re-training professional software personnel must rewrite applications.
As more and more users began using an AMD64-based compatible 32-bit calculated 64-bit computing system, the popularity of 64-bit calculations has become a general trend. The most obvious in the promotion team behind this change is Twilight and AMD two companies. AMD's Opteron processor makes 64-bit calculations into large-scale applications, and the Dawn launched A series 64-bit server has become a pioneer in 64 in China.
For the current market, there have been 64-bit servers, we describe its functional application, server itself design, expand performance, stability, etc., is designed to help users buy 64-bit server products that are suitable for enterprise needs.
1,64-bit server function classification
From the application type, it can be roughly divided into a primary domain server, database server, web server, ftp server, and mail servers.
A. Main domain controller
The main domain controller is a network, user, computer management center, providing a secure network working environment. The primary domain controller not only responds to the user's login requirements, but also synchronize and back up user accounts, WINS, DHCP databases, etc. between the server, and the main domain controller also do DNS services. More than 2,000 enterprise networks above more than 2,000 users, there is also a backup domain server to ensure the security of the network. Windows 2000 is much better than Windows NT as the main domain controller.
The system bottleneck of the primary domain controller is a memory, network, CPU, and memory configuration rule: In addition to the memory occupied by the operating system, each additional user needs to add 1KB memory to store user accounts.
B. Document server
The file server acts as a network of data storage warehouses, and its performance requirement is to quickly transfer data between users and server disk subsystems on the network. The main factor affecting system performance is the speed of the disk and the network subsystem. Memory as a cache of transmission data has a great impact on system performance. After using DMA technology, the Utilization of the CPU is very low, and it is generally not a system bottleneck.
The subsystem that has the greatest impact on the performance of the file server is as follows:
Disk: When providing a file to the client, the server has to read all the required data from the hard disk. Obviously, the magnetic disk subsystem is the primary system bottleneck.
Network: When overloaded or large data streams, the network card or network bandwidth may become a bottleneck. Memory: Insufficient memory limits the number of cache files, resulting in frequent access to hard drives, reducing system performance.
As can be seen:
1. With the increase of the number of users or the load of the load, the system performance has been improved, and the system can be seen as a network intensive calculation. Soon throughput reaches the vertex. As the task increases, disk read and write requests are intensified, and the system is turned to disk intensive operation. Once the disk utilization is high, system performance will decrease significantly.
2. In the case of large load, improve the performance of the disk subsystem effectively improve the number of supportable users.
3. In small load conditions, the faster network subsystem can greatly improve the peak of the system.
4. When the memory is insufficient, increasing the memory can significantly improve the performance of the system.
C. Database Server
The database engine includes DB2, SQL, Oracle, Sybase, etc.
Important subsystem
Memory: The most critical performance factor of SQL Server. The more memory, the less disk I / O.
Disk subsystem: Database is much larger than memory capacity, disk I / O operation is inevitable. Therefore, the disk subsystem is also part of the server key.
CPU: SQL Server can take advantage of SMP technology to perform multithreaded tasks, by using multiple CPUs, perform parallel operations for databases to improve throughput. In addition, SQL Server's click rate of L2 cache reaches 90%, so L2 is, the better.
D.Web server
The web server is used to respond to Web requests and run related applications. The performance of the server is determined by the content of the website. If the Web site is static, the system bottleneck is: network, memory, CPU. If the web server is primarily intensive (such as dynamically generating web pages), the system bottleneck is: memory, CPU, disk, network. Because these sites use the dynamic content of the connection database to generate transactions and queries, this requires additional CPU resources, and there is enough memory to cache and process the dynamic page. The network bandwidth is also important due to high click rate and a large number of dynamic data.
2, server selection strategy
When you choose a 64-bit server, you should first start from your own actual needs, on the basis of full reservation, and adequate demand analysis, then choose from the following aspects.
Determine the choice of brand
The system is best to be famous in the industry; there must be a fully specific product line; the entire system should have excellent manageability; in terms of data protection, advanced technology should have advanced technology; after-sales service and technical support system must be improved.
3,64-bit server purchase standard
After determining the level of the purchase server, it should focus on its performance indicators. For 64-bit servers, it is usually necessary to consider manageability, availability, scalability, security, and reliability.
A. Reliability of the server
It means that the server can provide continuous non-fault time, the less fault time, the higher the reliability of the server. If the client application server implements file sharing and printing, only the server does not stop failure within the user working time period, does not require the server 24 × 7 × 365 without fault operation, and the dawn introduced full range of 64-bit servers in the full range of 64-bit servers End products, such as R210A, I210A, etc., etc. For banks, telecommunications, aviation, even short-lived system failures, will also cause difficult losses. It can be said that reliability is the soul of the server. Its performance and quality are directly related to system reliability of the entire network. Therefore, the user must put the reliability of the server in the first place when purchasing. B. Manageable server
C. High availability
Key enterprise applications pursue servers, and the lavage system 24 × 7 × 365 is not stopped, and there is no trouble. Some server vendors use the server's full-year downtime accounting for the percentage of the entire annual time to describe the availability of the server. In general, the availability of servers refers to the percentage of the time of the server available for the user to use within a period of time. The more mature the server's troubleshooting technology, the higher the availability provided to the user. There are two ways to improve server availability: reduce the average fault interval of hardware and utilize dedicated functional mechanisms. This mechanism can automatically perform system or component switching to avoid or reduce unexpected shutdown at the time of failure. However, no matter which method is used, it is unlikely to open the system or component redundancy, of course, this also improves system costs. D. The scalability of the server
The scalability of the server is one of the important performance of the server. The upgrade feature of the server is due to the increase in the number of workstations or customers is random. In order to keep the stability and safety of the server, the scalable performance of the server must be fully considered.
E. Security
Security is the life of the network, and the security of the PC server is the security of the network. In order to improve the security of the server, the server component redundancy is very important. Since server redundancy is an effective way to eliminate system errors, ensure system security and maintenance system stability, redundancy is an important criterion for measuring server security. Some servers are fully redundant in power, network cards, SCSI cards, hard drives, and PCI channels, and also support the automatic switching of the PCI network card, which greatly optimizes the security performance of the server. Of course, equipment component redundancy requires two sets of exact same components, and greatly improves the system's cost.
4,64-bit server application performance
Show as a global range can provide 64-bit server products from thousands of yuan to billion yuan, as industry analysts: the emergence of ultra-low price 64-bit server, will greatly stimulate users' purchase psychology, one 64 The large-scale popularization of the bit server has become an unstoppable historical trend of the information industry.
Dawn 64-bit server compared to some of the current 64-bit platforms, the OpteronTM processor can implement fully compatible with existing 32-bit programs, and this compatible operation mode is completely hardware, not by low efficiency. Simulate 32-bit instructions to implement. Users can continue to use existing applications on the A Series Server platform, do not have to wait for developers or software vendors to recompile the source code of the program, which will save users to purchase a large number of purchases and related training fees.
Previous 32-bit architectural servers use the South-North Bridge structure server chipset, where the North Bridge Chip (MCH) integrates the memory controller, responsible for connecting processors and memory. During the operation, the processor needs to exchange a large amount of data exchange with memory, and these data exchange needs to pass the North Bridge chip (usually using a shared data bus mode). Although this bus can increase bandwidth by lifting the operating frequency (FSB frequency), it is still not enough relative to the performance of the processor calculation.
Dawn 64-bit server is further reflected in the SUMA standard while integrating the latest technology in the industry. Take the I220A server as an example, support two AMD OpteronTM 200 Series processors, can extend up to 12GB DDR 200/266/333 REG. ECC memory, integrated dual channel ULTRA320 SCSI controller, can be installed in the internal tape drive and 6 blocks Ultra 320 hot-swappable hard drive provides 4 64-bit PCI-X and a 32-bit PCI slot, and can be upgraded with hot-swappable redundant power and redundant fans. Configuring a new design of Dawn A Series Server Navigation Software, even a primary user can easily grasp the installation, configuration, and management of the 64-bit server. Dawn Server Hardware Monitoring System With the Hardware Monitoring Chip of the 8111 chip connection, the system hardware work state real-time monitoring, through the LCD screen to the user alarm, and newly increase the host-based network intrusion detection (IDS) alarm function. Based on how many years of 32/64-bit and super server systems design and development experience, the stability and reliability of the Twilight Heaven I220A servers also depends on the test, and the full load pressure test was tested for more than 72 hours in a 35-degree ambient temperature.
