Study Notes

Server Administrator Role

Maintains server performance and oversees its lifecycle through four phases: procurement, usage, end of life, and disposal/recycling.

Major Subsystems of Computer Systems

Processor (CPU): Dictates the processing power of the system.
Memory (RAM): Provides storage capacity for quick data access by the CPU.
Storage: Includes drives for operating system and user data storage, influencing access speeds.
Network: Facilitates the transmission of information across networks, vital for server communication.

Server Operating Systems (OS)

Linux: Comprises a family of variations known as distributions. Free and open-source, modified under the General Public License (GPL).
- Notable distributions include:
  - Red Hat: Enterprise deployment (RHEL), Fedora, CentOS.
  - Debian: Community-focused, includes Ubuntu and Kali Linux.
Windows Server: Common in business settings, offers centralized administration; closed-source and sold through Microsoft or resellers.

Troubleshooting Methodology

Follows structured steps for efficient resolution:
- Identify the problem and scope.
- Develop a theory of probable cause.
- Test the theory and establish a plan of action.
- Implement the solution and verify full system functionality.
- Conduct root cause analysis and document findings.

Workstation vs. Server Characteristics

Workstation:
- Assigned to end users; lacks redundancy and high performance.
- Uses client OS optimized for single user experience (e.g., Windows 10, macOS, Ubuntu Desktop).
Server:
- Secured in server rooms, includes redundant hardware for reliability.
- Runs server OS capable of supporting multiple users; typically has limited or no GUI.
- Physical features designed for optimized performance and management in a centralized setting.

Security Considerations

Workstations face higher security risks (theft, damage) due to proximity to users.
Servers are physically secured, regularly backed up, and supported by redundant components.

Common Responsibilities of Sysadmins

Install and manage server hardware, applications, and networks.
Monitor server performance and conduct capacity planning.
Troubleshoot issues and collaborate with various IT teams.
Manage user accounts and handle escalated service desk tickets.
Document processes and ensure compliance with security policies.

Skills and Qualifications for Sysadmins

May include formal technical training, relevant certifications, college degrees, and practical experience in the field.

Importance of Differentiating Workstations and Servers

Distinguishing features impact management and operational strategies; includes hardware redundancy and performance levels across devices.
