Server subsystems: memory, processor, disk, and network important point to watch for

Which subsystem has the greatest effect on each server environment?

Objective After completing this lesson, you will be able to describe the effect of each primary subsystem on server performance.

Server subsystems The four primary subsystems are:

Server memory is the subsystem that is most important to general server performance. If the server does not have enough random access memory (RAM) to hold the data that it needs, it must temporarily store the data on the disk. Disk access is much slower than RAM, so storing data on the disk can significantly degrade server performance.

The most important aspect of processor performance is its level of usage. When an application or other software uses more than its share of the processor's cycles, all the other software that is running operates much more slowly.

The access speed of the physical disk drive can greatly affect the speed at which applications operate and data is loaded. Also, the disk storage space must be sufficient for you to install applications, store data, and have enough space for the paging file.

The performance of your network is affected by the speed of both the hardware in your network infrastructure and the software that is running on your servers and clients.
