Server vs. High-End PC
Reliability and Performance
One of the most important differences between servers and high-end desktop computers is the use of higher quality hardware in servers that has built-in failproof protection in the form of redundancy. If a desktop component fails, it typically impacts only one user, whereas if a server component fails it can impact a large number of users or even an entire business.
Redundancy is particularly important for storage, where RAID (redundant array of inexpensive disks) is typically utilized to keep a server up and running even if a hard drive crashes, as well as for power, where backup power sources are utilized to keep a server operational even if the main power supply goes down. These components and other hardware in a server can typically be replaced with minimal or no disruption to users.
Servers also typically utilize hardware specifically tailored to the needs of businesses, including multiple processors and plenty of RAM to prevent performance degradation when supporting a large number of users.
