This IBM Redbook explores the evolution of the IBM RS/6000 SP system into the
IBM ^ Cluster 1600 and the impact of pSeries POWER4 LPAR
technology in the pSeries clusters. This publication also highlights the new
pSeries servers, which can be incorporated into Cluster 1600. This book
provides pSeries cluster configuration information, including hardware and
software hints and tips, as well as changes in the packaging of the cluster
management components: AIX 5L and Parallel System Support Program
An overview of Reliable Scalable Cluster Technology (RSCT) is included to
introduce the reader to the latest developments of the RSCT clustering software.
The latest enhancements in PSSP 3.5 are included, highlighting in particular the
changes made to the switch software and Virtual Shared Disks (VSD).
Configuration architectures and examples are included for customers planning to
deploy a Cluster 1600 in their computing environment. PSSP 3.5 and General
Parallel File System (GPFS) enhancements are explored, including the latest
64-bit support and the latest supported levels of AIX 5L.
This redbook also includes helpful information about software coexistence,
migration, and integration in Cluster 1600. Migration scenarios, hints, and tips are
provided for customers planning to migrate to the latest software levels in Cluster
1600. Finally, a high-level comparison between PSSP 3.5 and the new
IBM ^ Cluster 1600 Cluster Systems Management software is provided.
Appendices describing Cluster 1600 scalability rules, a sample switch
management script, PSSP hints and tips, and AIX device drivers are also
