Server Architecture: Past, Present, and Future – Part 3

The Future
One challenge that chip makers have juggled is the power requirements for faster chips and the heat output associated with them. In some cases, cooling fans and heat sinks have become inefficient ways to keep chips cool, leading a few to invest in liquid cooling and other unconventional methods.
As the world becomes more […]

Server Architecture: Past, Present, and Future – Part 2

Other companies that produce x86 processors include Cyrix, AMD, and VIA. AMD, in particular, has become Intel’s biggest competitor.
At the turn of the century, Intel introduced their high-powered 64-bit processor line called IA-64 or Itanium. Originally produced at HP, Intel later joined in the development with the intention of making server-class processors to […]

Server Architecture: Past, Present, and Future – Part 1

Servers have evolved significantly over the past three decades. At one time, a single server filed an entire room, required its own cooling system, and had processors that ran slower than many of today’s mobile phones. Today, servers are smaller, faster, and more energy efficient, but the most important element is still the […]

Use Mpstat to Monitor Multiple Linux Server Processors

Probably the first Linux tool you think of when you want to monitor CPU usage is “top”. Top is light and gives you a good glimpse of processes that are consuming processing power. One thing top will not do by default, however, is show you how each processor is working and how much of their […]

How to Set Processor Affinity for a Specific Task

Linux operating systems work very well with multi-processor servers. Today’s dedicated servers almost always have multiple processors or cores. When you have 4, 8, or even more logical CPUs, you can use Linux’s scheduling system to assign specific tasks to individual CPUs. As long as the task is assigned to that particular CPU, it will […]

A Breakdown of AMD’s Processor Numbering

A while back, we took a look at Intel’s Xeon processor numbering scheme to get a better idea of how their server CPUs are identified.  Intel, however, is not the only server processor manufacturer on the block.  Its direct competitor, AMD, has a server line called Opteron processors.
According to AMD’s specifications, every processor in […]
