Fundamentals of Server Hardware, Storage, and Network Interfaces
This article provides a comprehensive overview of server fundamentals, covering definitions, high‑performance characteristics, core components such as CPU, memory, disks and RAID, various CPU architectures, server classifications, C/S and B/S models, and detailed explanations of network interface cards, their functions, classifications, port types, and cable options.
Server is a high‑performance, high‑reliability computer that provides services to client machines, supporting applications ranging from email and printing to ERP, databases, big‑data services, weather forecasting, and high‑performance computing.
Typical server hardware consists of CPU, memory, disks, modules, RAID cards, together with power supply, motherboard and chassis.
CPU architectures include CISC (primarily Intel and AMD processors) and RISC (IBM Power series, Sun Spark series, and ARM‑based CPUs). Intel’s Xeon Scalable processors, introduced with the Purley platform, use a new naming scheme of Platinum, Gold, Silver, and Bronze.
Server categories span large mainframes for massive computation, small systems for finance, telecom and other industries, x86 servers based on CISC processors, and energy‑efficient ARM servers.
Client/Server (C/S) and Browser/Server (B/S) models describe typical deployment architectures, with servers running large databases such as Oracle, Sybase, Informix, or SQL Server, while clients use either dedicated software or a web browser.
Network interface cards (NICs) operate at the physical and data‑link layers, handling address representation, data encapsulation, link management, encoding/decoding, and data transmission.
NIC classifications cover bus types (PCIe, USB, ISA, PCI), form factors (integrated LOM, PCIe add‑in cards, Mezzanine cards), and application types (workstation vs. server). Port types include electrical RJ45 and optical interfaces (SFP+, SFP28, QSFP+). Cable options include DAC (direct‑attach copper) and AOC (active optical cable) for various speed and distance requirements.
