This episode covers the core elements of server storage management, beginning with provisioning storage volumes and assigning them to appropriate applications or users. We explain how disk quotas are implemented to control individual or group usage, how compression can save storage space without significantly impacting performance, and how deduplication identifies and removes redundant data blocks...

This episode focuses on integrating servers into directory services such as Microsoft Active Directory or LDAP-based systems. We explain how directory services centralize authentication, authorization, and resource management, and how servers join domains or directories to leverage these capabilities. Configuration steps include specifying domain controllers, setting DNS for proper resolution, and...

This episode explains how to configure servers for specific roles, including print servers, file servers, database servers, web servers, and application servers. We discuss the installation of necessary services or applications, the configuration of associated permissions, and the monitoring of role-specific performance metrics. The episode emphasizes how role configuration decisions impact server...

This episode explores the role of Media Access Control (MAC) addresses as unique identifiers for network interfaces. We explain how MAC addresses are assigned at the hardware level, how they are used in Layer 2 network communication, and how they can be filtered or whitelisted for access control. The discussion includes how MAC addresses appear in server NIC configurations and how they are referen...

This episode covers how to configure and manage server firewalls to control inbound and outbound traffic. We explain how rules are created based on IP addresses, protocols, and port numbers, and how these rules enforce access control to protect server resources. The discussion includes common firewall configurations for services such as HTTP, HTTPS, SSH, and RDP, and the difference between softwar...

This episode explains the differences between static IP addressing, where configuration is manually assigned, and dynamic addressing, where a DHCP server automatically provides network settings. We discuss when static addressing is preferred for servers, such as in cases where predictable connectivity is required for domain controllers or application hosts. We also explain Automatic Private IP Add...

This episode reviews IPv4 and IPv6 addressing protocols, including their structure, address classes, and the differences between public and private ranges. We discuss how private ranges under RFC 1918 are used in internal networks, while IPv6 introduces vastly expanded address space and features like auto-configuration. The discussion also covers address notation, subnetting basics, and the import...

This episode covers how servers resolve hostnames to IP addresses using Domain Name System (DNS) servers, local hosts files, and fully qualified domain names (FQDNs). We explain how DNS zones, records, and caching work, as well as the importance of configuring correct DNS server addresses on each server. Hosts files are discussed as a manual override for name resolution, useful in isolated or trou...

This episode explains the role of default gateways in directing traffic from a server to destinations outside its local subnet. We cover how to configure and verify gateway settings, how routing tables determine packet paths, and the impact of incorrect gateway assignments on connectivity. The discussion also includes static routes and when they are needed in addition to default routes. Practical...

This episode focuses on Virtual Local Area Network (VLAN) configuration and its role in logically segmenting network traffic. We explain how VLANs are identified by tags, how trunk ports carry multiple VLANs, and the importance of matching switch and server configurations for proper communication.
