The EMC E20-860 certification represents a critical benchmark for professionals seeking expertise in implementing and managing Network Attached Storage (NAS) solutions within enterprise environments. This credential validates the practical and theoretical knowledge necessary for deploying, configuring, and optimizing EMC NAS systems effectively. Candidates are evaluated on their ability to integrate EMC NAS solutions into complex IT landscapes, ensuring high availability, data integrity, performance optimization, and multi-protocol access. Mastery of these concepts requires an understanding of both storage fundamentals and advanced NAS technologies as deployed in enterprise-scale EMC solutions. The E20-860 exam measures the candidate’s ability to plan, implement, and troubleshoot NAS solutions while adhering to best practices established by EMC.

Overview of Network Attached Storage Architectures

Network Attached Storage (NAS) is a specialized storage architecture that delivers file-level data access over a network. Unlike block storage systems, which expose raw data blocks to clients, NAS systems provide organized file access, enabling multiple users and applications to access shared storage resources simultaneously. NAS simplifies storage management by centralizing storage resources, improving data availability, and allowing administrators to manage capacity and performance from a single interface. For the EMC E20-860 exam, understanding the underlying NAS architecture is essential for designing scalable, efficient, and resilient storage environments.

NAS architectures generally include storage controllers, disk arrays, network interfaces, and storage pools. Controllers are responsible for managing the flow of data between clients and storage devices, ensuring redundancy, and maintaining high availability. Network interfaces provide connectivity between client devices and the NAS system, supporting various file protocols such as NFS, CIFS/SMB, and FTP. Storage pools aggregate multiple physical disks into logical units, providing flexible allocation of storage capacity while optimizing redundancy and performance. Understanding the interplay between these components is critical for ensuring effective deployment, troubleshooting, and ongoing system management.

EMC NAS Platforms and Capabilities

EMC provides several NAS solutions designed to meet a wide range of enterprise requirements, including VNX, Unity, and Isilon storage platforms.
