ARM and Nvidia Architecture in Servers

If you go back further enough in time, you might find some servers running on SPARC architecture, but other than that, only three processor brand types have truly been dominant in the server market. Those are Intel, AMD, and IBM’s PowerPC. Lately, Intel and AMD in particular have dominated the server market with x86_64 architecture. […]

The Benefits of 64-bit Operating Systems

Most servers come with 64-bit processor architecture. For example, Intel’s Xeon line of processors as well as AMD’s Opteron processors are both capable of 64-bit instructions. Most modern desktop processors are also 64-bit. Nevertheless, there are still some users who might opt for 32-bit operating systems. Is there really a substantial difference and what are […]

How to Setup and Use KVM: Part 2

This guide will describe how to install and setup KVM on a Red Hat/CentOS server. The end result will be a system capable of hosting multiple virtual machines, all of which operate on a bridge network, meaning they are equally accessible within the same LAN and would appear to a remote user as though they […]

Back to the Basics #1: Server Hardware

Over the next couple of weeks, Dedicated Server School will post several articles in a series called “Back to the Basics”. Much of this will be a rehash of content we have already published, but it will be provided in a more uniform set of informative posts for those new to dedicated servers.
Part 1: […]

Monitoring Tips Using the ps Command

The ps command is an extremely powerful tool for monitoring processes on a Linux or Unix server.  Processes are the individual instances of a program running on your server.  With ps, you can find out which programs have running processes, how much memory they are using, how much processor power they are consuming, and which […]

A Breakdown of Intel’s Processor Numbering

There was a time when all you had to know about a processor was the clock speed.  Then, you knew your 486 was faster than your friend’s down the street.  Those days are long gone, and the complexity of processor power and naming systems for them makes deciphering the actual speed and power a bit […]

The Pros and Cons of Rolling Your Own Kernel

Some purists of the geek variety may have told you that their servers run faster than yours because they took the time to compile their own kernels from source.  They may even run a Linux distribution that encourages custom kernels.  In all likelihood, you have a dedicated server that runs an OS that uses a […]

5 Dedicated Server Hardware Tips

Whether you are leasing a server from a remote service or buying your own on-premise dedicated server, it is important to know what is under the hood and what you are getting for your money.  The following are five tips that should help you evaluate servers and make an informed decision.
1. Look for server-grade CPUs. […]

How to Increase MySQL Memory Usage Above 2GB

MySQL is a great database server for small, medium, and large websites, but large sites may find that the database alone can consume a great deal of system resources.  Ideally, you should be able to increase resources (i.e. more processors and more memory) in order to get better performance.  In reality, however, there are some […]

When a VPS is not Enough

It is never an easy decision to decide to purchase or lease a dedicated server. The increased cost and responsibility is more than some are willing to take on, unless they absolutely must. Virtual private servers (VPS) are a good way to have the best of both worlds: the autonomy of a dedicated […]

How to Assign a Process to a Specific CPU

Nearly all modern servers come with multiple CPUs or at least a CPU with more than one core. Operating systems see more than one CPU, and the advantage is that you can dedicate a CPU to a particular process, freeing up the other CPUs for less intense work. Done correctly, it will make […]

Choosing the Best Server CPU

It is easy to assume that a dedicated server host will provide you with the latest hardware, but the only real way to make sure of this is to evaluate the hardware specs they provide. Many new server administrators pay close attention to operating systems, control panels, and software, but neglect one of the […]
