Comprehensive Overview of Server, Storage, and Network Card Fundamentals

The article introduces the concept of servers as high‑performance, reliable computers that provide services to client machines, highlighting their role in enterprise applications such as email, ERP, databases, big‑data services, and high‑performance computing.

It outlines the main hardware components of a server—CPU, memory, disks, modules, RAID cards, power supply, motherboard, and chassis—and distinguishes between CISC (e.g., Intel, AMD) and RISC (e.g., IBM Power, Sun Spark, ARM) processor families.

It describes the evolution of server platforms, noting Intel’s Purley platform and the Xeon Scalable Processor family with Platinum, Gold, Silver, and Bronze tiers, as well as the differences among large‑scale mainframes, mid‑range minicomputers, x86 servers, and ARM‑based servers.

The article explains client/server (C/S) and browser/server (B/S) architectures, emphasizing the use of high‑performance PCs, workstations, or minicomputers on the server side and large database systems such as Oracle, Sybase, Informix, or SQL Server.

Chapter 2 covers server storage basics, detailing disk types, RAID concepts, and the importance of storage media, protocols, virtualization, backup technologies, and design considerations across nine chapters of a referenced storage guide.

Chapter 3 focuses on network card fundamentals, describing their role in the physical and data‑link layers of the TCP/IP model, functions such as address representation, encapsulation, link management, encoding/decoding, and data transmission.

The article classifies network cards by bus type (PCIe, USB, ISA, PCI), form factor (LOM, PCIe add‑in, mezzanine), and application (workstation vs. server), and distinguishes between copper (RJ45) and optical (SFP+, SFP28, QSFP+) interfaces, as well as cable types like DAC and AOC.
