What's Included:
Key Highlights
- NFS server and client configuration
- NFS security and performance tuning
- iSCSI target and initiator configuration
- CHAP authentication and network segmentation
- Block-level storage management
- LVM integration with iSCSI volumes
- Storage design for virtualization environments

- Production-ready network storage architecture
Overview
Design, deploy, and secure NFS and iSCSI storage on Linux. Configure targets, initiators, LVM integration, virtualization storage, performance tuning, and production-ready security.
The Problem
Network storage is often implemented hastily, without a full understanding of performance, security, and architectural trade-offs.
Common challenges include:
- Misconfigured NFS exports exposing sensitive data
- Insecure iSCSI targets vulnerable to network abuse
- Poor performance due to incorrect tuning
- Improper LVM integration with block devices
- Storage outages in virtualization clusters
Without a structured approach, network storage becomes fragile infrastructure.
The Solution
NFS & iSCSI: Linux Network Storage provides a systematic roadmap for deploying secure and resilient network storage on Linux.
You will learn how to:
- Choose the right storage model (file vs block)
- Deploy NFS securely and efficiently
- Configure iSCSI targets and initiators correctly
- Harden network storage with authentication and segmentation
- Integrate storage into virtualization environments
- Design scalable, production-ready storage systems
The result: reliable, secure, and performance-optimized Linux network storage infrastructure.
About This Book
NFS & iSCSI: Linux Network Storage is a practical, production-focused guide to designing, deploying, and securing network-based storage infrastructure on Linux.
Modern Linux environments depend on reliable network storage. Whether you're building a virtualization cluster, centralizing storage for databases, or designing scalable infrastructure, understanding both file-level and block-level storage is essential.
This book delivers deep, hands-on coverage of NFS for file-level storage and iSCSI for block-level storage, with iSCSI serving as the technical core.
