A total guide for buying a new server

Hawre Kamal

Dell produces a variety of different types of servers, each of which can be arranged according to your needs and requirements. Avesta provides all Dell servers in Iraq and has specialized staff in servers that can recommend the best server for your work.

What's server?
Simply a server is a powerful computer that serves a range of other computers, specifically designed to deliver information, software, and data to other computers that are linked to it connected to it via a network.

Why do I need a server?

  

When buying a server, you should consider three things:


What type of server do I need?
You need to know what kind of applications you're running on that server? How many users(clients) it will have? Simple tasks such as printing and sharing documents among users may require one simple, low-cost server, but tasks such as hosting large databases and image libraries require a server that has more processing ability with a set of fast hard drives.

Tower server: One of the basic types of servers, it costs and takes up as much space as the average desktop you can place it vertically on the table. because of its small size, it takes a small space in your office. It's good for small and medium businesses, especially if you need only a few servers and you can’t add a Rack server.
Dell has several models for this type of server and the generation of the 15 is the newest Dell servers:
Generation 15: T150, T350, T450
Generation 14: T40, T140, T340, T440, T640
Generation 13: T30, T130, T330, T430, T630


Rack Server: These types of servers are horizontally created and inserted into the Rack to protect it against dust and unauthorized people by locking the Rack. It also takes less space, because if you have multiple servers, they can be placed on top of each other. These servers are used for small, medium, and large businesses based on their models and features.
Dell models for The Rack Server:
Generation 15: R250, R350, R450, R550, R6500, R650xs, R6515, R6525, R750, R750xa, R750xs, R7515, R7525
Generation 14: R240, R340, R440, R540, R640, R6415, R740, R740xd, R740xd2, R7415, R7425, R840, R940, R940xa
Generation 13: R230, R330, R430, R530, R530xd, R630, R730, R730xd, R830, R930


Blade server (or modular): This type of server is a set of small-size servers in one box so that you can manage all servers together. These types of servers are good for large projects when you need to use many servers, especially if you want to create a local cloud. The Blade server means more processing, less size, less energy, less cost for management.
In Dell's model for this type of server:
Generation 15: MX750c
Generation 14: FC640, M640, M640, MX7000, MX740c, MX840c, MX5016s
Generation 13: FC430, FC630, FC830, FD332, FM120, M630, M630, M830, M830


Recognizing and identifying Dell servers:
All Dell's servers are called PowerEdge, which is the company's naming policy, and Dell Storage are called PowerVault and the switches are called PowerConnect. So how do we understand the Dell PowerEdge series of servers? How to read the models?

Three-digit model: For example, T550


Four-digit model: for example, R7515


After that we come to the server hardware configuration, which is one of the most important parts and has a complete impact on the server’s performance.


Another point we might hear is that this server is 2U. What does this mean? U means Rack unit, it is the server height, which can be 1, 2, 3, or 4U.

Then we need to choose an operating system for the server, and here we have options such as Windows Server, VMware ESXI, Linux Red Hat Enterprise, or Linux Suse Enterprise.
