Server Upgrade methods and considerations

As an important part of the Internet, the server plays a lot of important role, not only in the Internet industry, in the banking, supermarkets, enterprises, schools and other industries have been inseparable from the support of the server, its normal operation to our daily life has brought a lot of convenience, such as: Banking processing business system, enterprise management software. But with the increasing of information data, equipment continued aging and other reasons, server problems ensued, when the server carrying capacity reached a certain limit, management and maintenance personnel should consider upgrading the server to ensure that the rapid development of the server is the support of information construction.

In the consideration of the upgrade process, the user should be based on their own actual situation, the first to their own server configuration of the detailed understanding of the future needs of enterprises to analyze, carefully consider, and then develop the most suitable for the server upgrade program, in order to avoid unnecessary waste during the upgrade process. Here to provide you with some upgrade needs to pay attention to the place, I hope that everyone in the upgrade process can be helpful.

First, upgrade mode

　　1 , hardware upgrade: The server upgrade is mainly around CPU , memory, storage system and network card four aspects.

　　CPU : CPU is the CPU, English is Central processing Unit. CPU is the core parts of the computer, only the match box is so big, dozens of sheets of paper so thick, but it is a computer's core and control of the operation of the core. All operations in the computer are read by the CPU and the core components of the instruction are decoded and executed. Where many servers need to be upgraded,theCPU is running too slowly, resulting in limited application performance.

During the upgrade process, be aware of the server's architecture,CPUinterface and the most capable of supportingCPUquantity and so on. Currently widely used inPCServer hasInteland theAMDarchitecture servers, and some with desktop computersCPUlow-end servers. These servers are used by theCPUarchitectures are different, so the upgradeCPU, you need to know what kind of server the enterprise server is using, and then see if the server has an upgradeCPUof space. But in determining the upgradeCPUbefore, two concepts of transaction speed and concurrency processing performance must be clarified.

In addition, if the server accesses fewer customers, each customer needs the server to provide some kind of CPU rely on a large application service, then a high-speed single CPU may be the most useful. However, even a low-speed multi-CPU system may be more useful if there are many users who simultaneously request access to a large amount of data that is opened in a separate process or thread mode .

Memory: Memory bar is connected CPU and other devices, play the role of buffering and data exchange.

The maximum memory capacity that the server can support is generally limited, and if you plan to upgrade the server's memory, you need to understand the technical parameters of the server to avoid the requirement of upgrading.

Storage System: Server storage System upgrade is mainly two aspects, one is the expansion of capacity, and the other is to build RAID array with the aim of doubling the performance or doubling the security of the data, and even both.

If you plan to upgrade, be sure to understand whether the server board meets the requirements. View their compatible brand models.

Network card: Network card for the server is also a very important part of the network card throughput directly related to the overall performance of the server, if the server bottleneck in the network card, then the performance of a better CPU , and then large memory, and more hard disk capacity is a fake, so upgrade the server still need to pay attention to whether the network card has become a bottleneck problem.

Second, software upgrades: In addition to hardware aspects of improving product performance, software, we also want to optimize and debug, so as to further ensure that the server performance to achieve the best state.

Upgrade to SQL Server

For example: Database aspects, management software version aspects (ERP,OA , etc. ) relevant applications should be considered is not with our upgraded server compatibility.

Seven important things to remember to upgrade:

　　1 , users should fully evaluate their own needs and find the right technology. Can not blindly follow the sales staff, can not only buy advanced technology products, choose expensive, rather than choose the right, suitable for us is the best.

　　2 , the user to the hardware compatibility fully understand, so that their purchase of products can be very good compatibility. During the upgrade process, there are often a lot of wasted situations. For example: Although the most advanced CPU is bought , but its own server does not support, resulting in unnecessary waste.

　　3 , pay attention to the price trap. To fully understand the " Penny- a -Penny " of the road, in China, low-cost sales are often the manufacturers throw the trap to customers, and some users are very sensitive to the price, so often in the strokes.

　　4 If the reason for a user upgrade is a resource shortage, such as CPU too slow, memory is too small resulting in limited application performance, it is recommended to extend the resources on the basis of the original platform architecture, such as selecting faster CPU , more memory, larger disk capacity, more CPU , do not in Unix minicomputer, PC Server, New - High-performance servers, and not even change CPU types and operating systems.

　　5if the user's needs are not met because of the original schema, such asPCServer'sCPUnumber, memory size is limited, or4 CPU Unixthe storage of the minicomputer can be limited, it is recommended to upgrade the system capability on the same system, such as2RoadPCServer Upgrade to4Road or8Road,4RoadUnixsystem upgrade to8Road or -Road, WillSCSI RAIDReplaceFC SANand so on.

　　6 , if the user is upgrading because the user needs due to the application of the architecture of the reasons can not be satisfied, you may consider changing the system architecture ; If all applications run in a SMP system performance is limited, can be used in cluster system decentralized application, improve the expansibility ; also as the database in PC the server is subject to I/O the impact of bandwidth cannot guarantee transaction processing power, can be upgraded to large SMP Unix System.

　　7, if the reason for the user upgrade is due to cost-saving considerations, you can refer to the following approximate formula;at present, the price ratio of the server is approximate, highPC:XeonServer:UNIXServer= 1:2:4;In addition, the cluster system: largeSMPsystem= 1:2, the user can choose the platform according to the fund situation.

Summary: Just now in the above article has been mentioned, hardware upgrade is one, software optimization server can also let the old machine to play the heat ( such as using virtualization technology to make our servers more efficient ) . At the same time also note that the hardware update speed is much higher than the software update speed, in the purchase of server products we have to carrot, both hands are hard to grasp. As far as possible 2 years after the position of thinking, to make estimates, so as to ensure that the server continues to meet the needs of the application.
