Configuration and Tuning GPFS for Digital Media ... - IBM Redbooks

Preface
This IBM® Redbooks® publication discusses the architecture and applications to
provide an understanding of the performance impacts that GPFS components
have on applications in a digital media environment, and how to avoid pitfalls and
to take advantage of the parallel features of GPFS.
This book has a step-by-step guide for configuring a GPFS cluster on Linux® on
pSeries®, and a tuning section that lists and explains parameters and software
components sorted by their impact on performance and availability, with special
considerations for digital media solutions.
The book provides guidance and advice about how to implement GPFS in a
digital media environment and how to choose the best configuration for each
particular implementation. For those of you looking for a deeper understanding of
GPFS, you will find this book very helpful and detailed. Although this book does
not provide extensive problem determination for GPFS, it contains many hints,
tips, and work-arounds for common problems or misconfigurations.
