Logical Partitioning (LPAR)
LPAR allows workloads from multiple systems to be consolidated to a single pSeries machine, thus
significantly cutting IT costs while minimizing risk. LPAR involves a single pSeries system’s resources
(processors, memory, etc.) being divided to create multiple independent pSeries systems within the same
system. The end result of this pSeries partition is the system being “separated” into a primary partition
and one or more secondary partitions. Each pSeries partition can then be used for different purposes,
such as database operation or to separate test and production environments, and can communicate with the
other partitions as if they were each in a separate machine.
ESG’s LPAR services offer the planning and guidance of an experienced LPAR consultant and include:
- Hardware design and planning
- On-site inventory and LPAR validation tool (LVT) review
- Installation of the pSeries server, including set up and configuration of the LPARs
- Loading secondary partitions with appropriate operating system
- LPAR configuration documentation
