Book description
IBM® PowerHA® SystemMirror® for i is the IBM high-availability (HA), disk-based clustering solution for the IBM i operating system. When PowerHA for i is combined with IBM i clustering technology, it delivers a complete HA and disaster-recovery (DR) solution for business applications that are running in an IBM i environment. You can use PowerHA for i to support HA capabilities with either native disk storage, IBM DS8000® storage servers, or IBM Storwize® storage servers.
This IBM Redbooks® publication gives a broad understanding of PowerHA for i and provides a general introduction to clustering technology, independent auxiliary storage pools (IASPs), PowerHA SystemMirror products, and the PowerHA architecture.
This book is part of a four-book volume set that gives you a
complete understanding of PowerHA for i and its use of native disk
storage, IBM DS8000 storage servers, or IBM Storwize storage
servers. The following IBM Redbooks publications are part of this
PowerHA for i volume set:
IBM PowerHA SystemMirror for i: Using DS8000,
SG24-8403
IBM PowerHA SystemMirror for i: Using IBM Storwize,
SG24-8402.
IBM PowerHA SystemMirror for i: Using Geographic Mirroring,
SG24-8401
Important: The information that is presented in this volume set is
for technical consultants, technical support staff, IT architects,
and IT specialists who are responsible for providing HA and support
for IBM i solutions. If you are new to HA, first review the
information that is presented in this book to get a general
understanding of clustering technology, IASPs, and the PowerHA
architecture. You can then select the appropriate follow-on book
based on the storage solutions that you are planning to use.
