Summary

"Rely on this book for information on the technologies and methods you'll need to design and implement high-availability systems...It will help you transform the vision of always-on networks into a reality."-Dr. Eric Schmidt, Chairman and CEO, Novell Corporation
Your system will crash! The reason could be something as complex as network congestion or something as mundane as an operating system fault. The good news is that there are steps you can take to maximize your system availability and prevent serious downtime. This authoritative book will provide you with the tools to deploy a system with confidence. The authors guide you through the building of a network that runs with high availability, resiliency, and predictability. They clearly show you how to assess the elements of a system that can fail, select the appropriate level of reliability, and provide steps for designing, implementing, and testing your solution to reduce downtime to a minimum. All the while, they help you determine how much you can afford to spend by balancing costs and benefits. This book of practical, hands-on blueprints:
* Examines what can go wrong with the various components of your system
* Provides twenty key system design principles for attaining resilience and high availability
* Discusses how to arrange disks and disk arrays for protection against hardware failures
* Looks at failovers, the software that manages them, and sorts through the myriad of different failover configurations
* Provides techniques for improving network reliability and redundancy
* Reviews techniques for replicating data and applications to other systems across a network
* Offers guidance on application recovery
* Examines Disaster Recovery
