This book focuses on the operating system, the underlying hardware, and their interactions. Topics covered include: Real and perceived performance problems, introducing capacity planning and performance monitoring highlighting their strengths and weaknesses. An integrated description of all the major tools at a system administrator's disposal for tracking down system performance problems.
Background on modern memory handling techniques, including the memory-caching filesystem implementations in Solaris and AIX. Updated sections on memory conservation and computing memory requirements. In depth discussion of disk interfaces, bandwidth capacity considerations, and RAID systems. Comprehensive discussion of NFS and greatly expanded discussion of networking.
Workload management and code tuning. Special topics such as tuning Web servers for various types of content delivery and developments in cross-machine parallel computing For system administrators who want a hands-on introduction to system performance, this is the book to recommend.
In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel.
The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks. The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel.
Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Bilbrey and Tom Syroid. Sanchez-Montanes, S. Ramos, R.

Dassen Ray and I. Russell, D. Quinlan, C. Introduction to Unix by F. Fiamingo, L. It steps you through the various phases of the migration process, using detailed case studies to illustrate the benefits, costs, and requirements associated with a migration project.
While this book focuses on UNIX server migrations, the methodology and best practices presented apply for most migrations to the Solaris environment. They can be used for projects ranging from the smallest data conversion to the largest legacy migration Readers involved in technical and sales support can learn the capabilities and limitations of the system; applications developers can learn effectively and efficiently how to interface to the system; system administrators can learn how to maintain, tune, and configure the system; and systems programmers can learn how to extend, enhance, and interface to the system.
The authors provide a concise overview of FreeBSD's design and implementation. Then, while explaining key design decisions, they detail the
