Once you have determined that your business needs servers, the first question you need to consider is whether you can use high-end desktops instead of buying new servers. This is a common problem, especially when resources are limited and budget constraints are tight.
Is the core hardware platform of an enterprise's information system built with high-end computers? Or are you using professional servers? Many decision makers and information system managers of small and medium-sized enterprises hesitate to purchase and build their own enterprise information systems.
Although high-end PCs are often used as server functions when necessary, especially for important roles such as file services. Several reasons show that using dedicated servers is a better long-term investment.
Compared with high-end PCs, dedicated servers have the following advantages::
Reliability and performance
Scalability
Security
Save long-term costs
Reliability and performance
One of the major differences between servers and high-end desktops is that servers use higher-quality hardware with built-in redundant forms of failproof protection. If a desktop component fails, it usually affects only one user. If a server component is damaged, it will affect a large number of users, or even the entire business.
Redundancy is especially important for storage. Even if a hard drive fails, RAID Redundant Array of cheap disks is usually used to keep the server running normally, including power, even if the primary power supply fails, the backup power supply can be used to keep the server running. In a server, these components and other hardware are usually replaced with the minimum, without affecting the user.
Servers usually also use hardware specifically for enterprise needs, including multiple processors and enough memory to prevent performance degradation when a large number of users are supported.
Servers can use ECC memory, RAID technology, hot swapping technology, redundant power supplies, redundant fans, and box locks to provide high fault tolerance and high security protection capabilities. And provides continuous and reliable operation.
