Examples of IT Server Types

There are several types of servers, each designed to fulfill specific functions or roles within an organization’s IT infrastructure. Some common types of servers include:

 

Web Servers

These servers host websites and web applications, responding to client requests for web pages and delivering content over the internet using protocols such as HTTP and HTTPS.

Database Servers

Database servers store, manage, and provide access to databases, allowing users and applications to store, retrieve, and manipulate data.

File Servers

File servers store and manage files and directories, providing centralized storage and access control for users and applications within an organization’s network. They allow users to share files, collaborate on documents, and access shared resources. Common file server protocols include Server Message Block (SMB)/Common Internet File System (CIFS) and Network File System (NFS).

Email Servers

Email servers manage email communication, handling the sending, receiving, and storage of email messages for users within an organization. They support email protocols such as Simple Mail Transfer Protocol (SMTP), Post Office Protocol (POP), and Internet Message Access Protocol (IMAP).

Application Servers

Application servers host and execute applications, providing runtime environments and services for running application code. They support various programming languages and frameworks and often include features such as transaction management, security, and scalability.

Virtual Servers

Virtualization servers host virtual machines (VMs) or containers, allowing multiple virtualized operating systems and applications to run on a single physical server hardware. They provide resources and management capabilities for virtualized environments, enabling server consolidation, resource optimization, and workload isolation. Virtual servers shouldn’t be confused with cloud servers or cloud computing though the concepts are related. In essence, virtual and cloud server management have the same key metrics to consider as other types of servers.

 

Server Hardware Management

Server administration includes both hardware and software management, which we’ve covered in a separate blog. Hardware management involves overseeing the physical components of servers to ensure their proper functioning, reliability, and performance. Key components of server hardware management include:

Processors (CPUs)

The central processing units (CPUs) are responsible for executing instructions and performing calculations. Server hardware management involves selecting CPUs with appropriate specifications (such as clock speed, number of cores, and cache size) to meet the computational demands of server workloads.

Memory (RAM)

Random-access memory (RAM) is used to temporarily store data and instructions that the CPU needs to access quickly. Server hardware management includes ensuring that servers have an adequate amount of RAM to support their workload requirements and optimizing memory configurations for performance.

Storage Drives

Servers use various types of storage drives, including hard disk drives (HDDs), solid-state drives (SSDs), and hybrid drives. Server hardware management involves selecting the appropriate storage technology based on factors such as capacity, performance, reliability, and cost, as well as configuring RAID (Redundant Array of Independent Disks) for data redundancy and performance improvement.

Power Supplies

Power supplies provide electrical power to the server components. Server hardware management involves selecting power supplies with sufficient capacity and efficiency to meet the power requirements of the server hardware, as well as implementing power management strategies to reduce energy consumption and minimize downtime due to power-related issues.

Cooling Systems

Cooling systems, including fans and heat sinks, are essential for dissipating heat generated by server components and maintaining optimal operating temperatures. Server hardware management includes ensuring proper airflow and ventilation within server enclosures, as well as monitoring temperature levels to prevent overheating and component failure.

Chassis and Enclosures

The chassis and enclosures house the server components and provide physical protection and support. Server hardware management involves selecting server chassis and enclosures with appropriate form factors, expansion capabilities, and durability to meet the server deployment requirements, as well as ensuring proper cable management and airflow for optimal performance and reliability.

 

Important IT Server Management Metrics and KPIs to Look Out For

Key Performance Indicators (KPIs) and server monitoring metrics play a crucial role in assessing the health, performance, and reliability of server infrastructure. Some important KPIs and server monitoring metrics include:
