The biggest benefit for LPARs is that they can be managed online. The CPU, Memory and adapters can be allocated on the spot without downtime, offcourse due care has to be taken. The process is also referred to as DLPAR. DLPAR is nothing but a daemon which runs on server. The name of the process is IBM.drm. Without this DLPAR is not possible, so far as I know.

Difference between LPAR and VIO Server

Posted on December 31, 2008 by Ganesh Sharma

VIO server is a special case of LPAR. In this the IOs are all virtual and provided to the partitions on VIO Server. Means IO slots, CPUs and Memory are all virtual. So, how is this done?

Difference Between Physical and Virtual Processor

Posted on December 28, 2008 by Ganesh Sharma

Virtual Processor is logical entity. The physical processor is divided into processing units. And one or several processing units are combined together to make virtual processor. The processing capacity is distributed in terms of virtual pr

Capped and Uncapped Processor Sharing Modes

Posted on December 28, 2008 by Ganesh Sharma

In capped mode the processing units given to a partition can not exceed the assigned processing units (entitled capacity

POWER HyperVisor and Its Functions
