Comprehensive and Detailed Explanation From Exact Extracts: Direct Attached Storage (DAS) has limited scalability, as it is physically connected to a single server, restricting the ability to expand storage capacity or share resources across multiple systems compared to NAS or SAN. DAS is simpler for deployment, not inherently costly, and supports block-level storage, but its scalability constraint is a key drawback for growing offices.

Direct Attached Storage (DAS), Network Attached Storage (NAS), and Storage Area Networks (SAN)." Reference: Dell PowerEdge Foundations v2 Exam Description (D-PE-FN-01), Topic: Introduction to Servers (28%).

The Open Compute Project (OCP) card is designed to enhance scalability and connectivity in PowerEdge servers by providing flexible, high-speed network interfaces without consuming standard PCIe slots. OCP cards support advanced networking and management features, offering modular upgrades for connectivity beyond basic LOM or integrated controllers. RIO cards focus on management ports, not scalability, while LOM is fixed and less flexible. OCP's modular design aligns with modern server needs. Exact extract:
