Server Selection considerations

Now there are many server generation manufacturers and more product series. When the company's business continues to expand, it is necessary to select and purchase servers. This requires refining various situations to choose different Server products.

The general direction is to balance cost and performance. In particular, small and medium enterprises or entrepreneurial enterprises should pay special attention not to save money, resulting in the Situation of marathile, the system performance cannot keep up, thus affecting the business. Of course, large enterprises should also try their best to avoid the use of high-end servers as soon as possible, and spend a lot of money to purchase high-end servers. However, the actual work is idle. How can we achieve or approach this balance? I personally think we should start with determining the application business type.

In terms of application services, conventional enterprises generally have file services, database services, web services, mail services, and download services. Each application has different focuses and requirements on server performance.

Application Service	Performance focus
File Service	Disk Io
Database Service	CPU, memory, disk Io
Web Services	Network I/O, memory, CPU

The primary selection of server products for these focuses will result in price and cost factors. Small and medium enterprises can select Server products with better focus as much as possible within acceptable scope. Then confirm the availability, reliability, manageability, and scalability of these types of servers. These are of course tests.

The test can be divided into several subsystems, including memory subsystem, disk subsystem, CPU, and network subsystem. There are various tools such as netperf network performance testing tools, LoadRunner load stress testing tools, and iometer testing tools. The testing standards are based on the company's business requirements. You can further filter these servers.

The second is the after-sales service and manageability of the server. If the machine crashes, you have to contact the IDC staff for half a day and then confirm to help restart the machine. The efficiency does not affect your business. If you have a convenient management interface, you can solve the problem quickly and efficiently. Small and medium-sized enterprises may not have professional personnel and may experience hardware damage. The delay in service recovery caused by the drag and drop of after-sales services is also quite tricky.
