In this lecture, you'll learn how to create, manage, and restore snapshots on Dell EMC Unity VSA. We'll explore snapshot scheduling, retention policies, and how snapshots support data protection and recovery.

In this lecture, you'll learn how to configure replication between Dell EMC Unity VSA systems. We'll cover replication sessions, policies, connectivity setup, and how replication supports disaster recovery and high availability.

In this lecture, you’ll get an overview of TrueNAS, an open-source enterprise storage platform. We’ll explore its editions (CORE, SCALE, Enterprise), use cases, supported protocols, and why it's a strong alternative to commercial storage systems.

In this lecture, you'll learn the fundamentals of ZFS — a powerful, enterprise-grade file system and volume manager. We'll cover its key features like copy-on-write, checksumming, self-healing, snapshots, and storage pooling.

In this lecture, you'll learn the internal architecture of ZFS, including vdevs, storage pools, datasets, ZVOLs, ARC/L2ARC caching, and how ZFS ensures data integrity through copy-on-write and end-to-end checksumming.

In this lecture, you’ll learn how to deploy TrueNAS SCALE in a virtual lab environment. We’ll walk through downloading the ISO, installing the system, initial configuration, and preparing the platform for storage setup.

In this lecture, you'll explore the TrueNAS web interface, including dashboard navigation, system settings, storage configuration, network setup, and available services. You'll learn how to efficiently manage the platform through its intuitive GUI.

In this lecture, you’ll learn how ZFS organizes storage using zpools and vdevs, and how different ZFS RAID types (mirror, RAID-Z1/2/3, striped) impact performance, redundancy, and capacity planning.

In this lecture, you'll learn how to create and configure an NFS share from a ZFS dataset in TrueNAS. We’ll cover permissions, network access control, and how to mount the share on a Linux VM.
