[Guangzhou server recycling] Five tips you need to know during server maintenance

Most people think that the server is only the Upgraded desktop. But anyone who has worked in a data center knows that they are quite different.

Even though Web servers load millions of visitors every day, they are still mysterious to common users. The following are five things you may not know about the server.

No monitor
Anyone who has watched movies like "Mission Impossible" knows that a highly secure server is placed in a "closed room" with a pull monitor and keyboard. Guangzhou server recycling]

But this is not the case. In technology, we talk about "server boxes" because they have very few input devices, such as monitors, keyboards, or mice, the reason is that these machines are not designed for humans to sit in front and use them directly.

On the contrary, they are designed to be very compact, so that they can be easily stacked together to occupy as little space as possible. The input device is not only useless, but also a waste of space.

Most configuration work and interaction with the server are done remotely-usually on the console. To achieve maximum performance, they do not provide GUI operating systems that require expensive CPU cycles to render graphics. All its functions are accessed from a secure distance through the command line.

Most people do not run Windows
In the desktop world, most computers run either Windows or Mac OS.

However, the server environment is completely different, and the diversity of operating systems is amazing. Some companies insist on using highly specialized server software to meet their needs. As early as 2008, some experts showed that Linux was installed on about 60% of servers. Linux has dominated the Web server industry in the past and recent years.

This is not surprising, given that content management systems such as WordPress or CMS account for 19% of all website deployments. WordPress runs on PHP and is best implemented in Linux. As long as there are powerful applications designed for Linux, its market share will continue to grow.

They generate a large amount of heat
The data center is notorious for consuming a large amount of electricity. Unfortunately, most of the energy is wasted on heat.

When you have thousands of server chassis close to each other, the heat generated is huge. To improve the energy efficiency of data centers, a lot of work is centered around finding ways to reduce heat generation.

It is not surprising that a cold country like Iceland positions itself as a data center hub. Their environment is most conducive to making a bunch of servers boast calmly... [recycling servers in Guangzhou]

It may be virtual.
You think the server that runs code or processes the website may not be "real" at all "!

In fact, with the popularization of cloud computing in the world today, you will almost certainly interact with virtual machines that share space with many others on the same hardware. This is expected.

The current server is very powerful and can easily support many "virtual servers" at the same time ". This allows data centers and enterprises to quickly set and delete resources to meet the needs of dynamic environments.

Parts are hot swappable
Imagine what if you had to replace the hard disk on your computer without shutting down your computer?

Impossible, right?

The fact is that servers need to be maintained constantly and they are built in a modular manner, so they can almost replace any resources on the server without disrupting its functions for a long time. Almost everything can be upgraded and "Hot swappable ."
