Concepts for partitioning the server
There are many different ways in which you can partition a server.
You can assign some resources directly to logical partitions, and you can
share other resources among your logical partitions to make your server more
flexible and reduce the amount of maintenance that you must perform. A thorough
understanding of the ways in which you can partition a server will allow you
to take the fullest advantage of the capabilities of your server.
Partitioning with version 7 or later of the HMC
The Hardware Management Console (HMC) is a system that controls
managed systems, including the management of logical partitions and use of
Capacity Upgrade on Demand. Using service applications, the HMC communicates
with managed systems to detect, consolidate, and forward information to IBM® for
analysis.
Partitioning with version 6 or earlier of the HMC
The Hardware Management Console (HMC) is a system that controls
managed systems, including the management of logical partitions and use of
Capacity Upgrade on Demand. Using service applications, the HMC communicates
with managed systems to detect, consolidate, and send information to IBM for
analysis.
Partitioning with the Integrated Virtualization Manager
The Integrated Virtualization Manager is a browser-based system
management interface that you can use to manage a single managed system that
uses IBM® Virtual I/O Server on a management partition. You can use the Integrated
Virtualization Manager to create logical partitions on a single managed system,
manage the virtual storage and virtual Ethernet on the managed system, and
view service information related to the managed system.
Partitioning with the Virtual Partition Manager
The i5/OSVirtual Partition Manager allows you to create and
manage up to four Linux logical
partitions from a single i5/OS logical
partition. You can use the Virtual Partition Manager to
partition any IBM System i5® or eServer™ i5 model
that does not require a Hardware Management Console (HMC), such as a model 595.
Partitioning using the Virtual I/O Server
The Virtual I/O Server provides virtual storage and shared Ethernet
capability to client logical partitions on the system. It allows physical
adapters with attached disks on the Virtual I/O Server logical partition to
be shared by one or more client partitions. Virtual I/O Server partitions
are not intended to run applications or for general user logins. The Virtual
I/O Server is installed in its own logical partition.
