Dedicated server: what is it, it’s purpose, how to choose one


The dedicated or personal server is a compulsory service on the hosting market. It benefits when the client needs perfect quality and excludes suspicious threats.

When the personal server is important

The virtual environment or physical equipment here doesn’t matter. It’s a satisfactory solution for the media server. That means all resources will be under its control, including the space. Yeah, the virtual private server may be the alternative, but it may be difficult for the user to guarantee high quality due to the hypervisor’s decisions regarding the allocation.

It’s easier to build the corporate network on a dedicated server. The administrator has much auxiliary equipment to deploy: USB keys, radio modems, etc. Nobody will know about that.

The third option is big data and scientific research, which need significant resources. Any virtual private servers will lose compared to the entire personal unit due to the limited resources. The latter algorithm supposes the participation of the hypervisor in allocating the resources. So the more prioritized or busy website will take more memory. It’s easier to install the graphic processor units or data storage coordination when the customer fully controls its server.

The cloud networks open new possibilities. Yeah, it’s virtual technology, but the customer may feel comfortable when they understand the system is private. It may release everything it wants, including the cipher mail server. The single resource on the equipment has a higher reputation than the shared system as there is a risk of reducing the position in ranking thanking the malware or impact from the advertising sites.

How to choose the dedicated server

The customer’s task is to understand the project. For example, video games and 3D modeling are more demanding than the company mail platform. So let’s learn when you need a bigger volume capacity or a more robust processor.


It’s the heart of the total system. Remember, there are two processors – the central and graphic unit. The first deals with the dedicated server 10 gbps technical parameters, text, and simple graphics. Some tasks don’t matter the frequency, while others need a whole load of all cores.

Xeon Gold or Xeon Silver family deals with video encoding and virtualization. However, these powerful monsters operate longer when the graphic processor unit takes a significant part of the processing. Xeon E series is the heart of corporate databases and enterprise management. Some operators provide free OS, but the monthly cost depends on the number of cores. Choose their minimal number and as higher performance as possible. 

Look at these parameters:

  • Clock speed in MHZ (or GHz frequently) doesn’t mean the processor counts the time. It shows how many operations it performs per second. The maximal known speed is 3 GHz for the central unit.
  • Cores. These are individual units for specialized tasks. For example, core 1 participates in audio control, the second is responsible for the text, and the third reads the system…
  • Threads. That means the number of processes the chip can handle simultaneously. Each core generates not a single thread but multiple of them. Any part of these threads is virtual and comes in parallel. The bigger capacity increases the chip performance and affects the server potential.

Cache. The system uses a cache to access the information. It contains the data of copying, last opened programs, or errors log. 

  • That helps to load the secure page or install any fragment quicker. The cache has a proportional balance between speed and volume. The L1 cache is the tiniest and the fastest one, while the L3 is the largest and the smallest. Nobody can turn and change the size of the processor cache.

Random-access memory

The purpose of RAM is to serve the applications. It’s the second step in the memory lineup. If the applications keep the launch data or some optional settings, they’ll work faster. Random access memory is rarely accessible for the user data. The factors affecting its choice are:

  • The number of users:
  • Size and number of various databases:
  • Execution packages;
  • Requirements of the operating system.

Disc drive

The SDD is the third in the memory lineup. These devices are equal to the L3 cache. It’s slower than the RAM, but the solid disc performs the maximal data volume. However, they have limited space compared with SATA or HDD. The latter have a slower access time but have several terabytes of capacity.

When the article’s author lost one of his hard disks on a PC, the repairman said that SSD fits its configuration but is sensitive to space occupancy. The maximal speed is guaranteed till the one-third load. If the percentage crosses 70%, it reduces the hard drive speed. This rule is actual for servers too. Despite this disadvantage, the solid drives serve longer, so they’re the best solution for long-term projects or big data resources.

SATA- and hard drives help when the organization needs the disk capacity in priority of speed. Their mix is possible, too, offering a broad palette of options for the employees or customers. SSDs are used for storing databases or service information. Their higher capacity friends provide access to the key data.


The price is the most decisive aspect. Start from the cheapest configuration, about $100 per month. Your volume will grow monthly, and you’ll consider more expensive server rental. That’s lucrative because the traffic is increasing. Any required additions or removals are available 24/7/365.
