Fault Tolerant Storage Multipathing and Clustering Solutions for Open Systems for the IBM ESS

Clustered environments are growing in popularity in today's computing environments. Many customers require that their businesses are running 24/7/365. This IBM Redbook tells you how to integrate multiple paths to the ESS disks in a clustered environment while improving availability and throughput of your disk channels.

The IBM Enterprise Storage Server is a highly available, scalable and reliable, SAN-ready storage server, and its success is growing in the storage marketplace. Inside this book you will find how multipathing can improve total system reliability, and which multipathing software is supported for use with the IBM ESS. This combination gives you fault tolerant storage.

This redbook answers some important questions:
Are your connections to the ESS reliable enough?
Did you eliminate all single points of failure in your environment?
Are some of your connectivity channels to the ESS overloaded, while others are idle?
Do you need to improve your data paths, but you don't know how to do it?
You will find how disks are seen in a multiple path environment and how they are treated by the operating system. You can learn how to load-balance your channels and establish multiple paths to a single disk, while still maintaining data consistency on this disk. You'll discover all of this using the ESS storage server, on many operating systems, including IBM AIX, Microsoft Windows 2000, HP-UX, Sun Solaris and others.
