This article mainly explains "what points to pay attention to in server upgrade". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what are the points to pay attention to in server upgrade?"

1. Users should fully evaluate their needs and look for suitable technologies. Neither blindly listen to the server sales staff, nor only buy advanced technology products, choose expensive, it is better to choose the right, suitable for our server is the best.

2. Users should fully understand the compatibility of hardware, so that the products they buy can be well compatible. In the process of upgrading, there is often a lot of waste. For example, although you buy the most advanced CPU, your own server does not support it, resulting in unnecessary waste.

3. Pay attention to the price trap. Fully understand the road of "every penny, one cent". In China, low-price sales are often a trap thrown by manufacturers to customers, and some users are very sensitive to price, so they are often caught.

4. If users choose server upgrade because of resource shortage, for example, CPU is too slow and memory is too small, which leads to limited application performance, it is recommended to expand resources based on the original platform architecture, such as faster CPU, more memory, larger disk capacity, more CPU, do not migrate between Unix minicomputers, PC servers, new 64-bit systems, high-performance servers, or even do not change the type and operating system of CPU.

5. If users choose a server upgrade because their needs cannot be met due to the original architecture, such as the limited number of CPU and memory size of PC servers, or the storage capacity of 4 CPU Unix minicomputers, it is recommended to upgrade system capabilities on similar systems, such as upgrading 2-way PC servers to 4-way or 8-way, 4-way Unix systems to 8-way or 16-way, and replacing SCSI RAID with FC SAN.

6. If the reason why the user chooses the server upgrade is that the user's needs can not be met due to the application architecture, you can consider changing the system architecture; for example, if all applications run on a SMP system with limited performance, you can use cluster systems to distribute applications to improve scalability; another example, the database on the PC server can not guarantee transaction processing capacity and can be upgraded to a large-scale SMP Unix system.

7. If users choose server upgrade for cost-saving considerations, you can refer to the following approximate formula; the current price ratio of servers is similar to that of high-end PC: Xeon servers: UNIX servers = 1: 2: 4; in addition, cluster systems: large SMP systems = 1: 2, users can choose platforms according to their funds. Server hardware upgrade is one of them, software-optimized servers can also make old servers play waste heat (for example, using virtualization technology can make our servers very fast. At the same time, we should also note that the speed of hardware update is much higher than that of software update. When we choose and purchase server products, we should use both hardware and software.) the last point is to think about problems and make estimates as far as possible in 2 years' time. Only in this way can the server continuously meet the application needs.

At this point, I believe that everyone on the "server upgrade need to pay attention to what points" have a deeper understanding, might as well to the actual operation of it! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
