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.
- Notable distributions include:
- 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.
