POWER HyperVisor and Its Functions

December 28th, 2008

What is POWER Hypervisor

POWER Hypervisor or simply known as Hypervisor is a piece of firmware.

What is its major benefit

It’s used to support the shared processor technology on p5 systems.

Where does it reside

The software code resides in the flash memory of service processor. It’s the underlying control mechanism which resides below Operating Systems. It owns all of the resources and creates partitions by allocating and sharing these resources.

What functions are performed by POWER Hypervisor

The Hypervisor performs the following function:

  1. It initializes and configures the processors.
  2. It provides virtualization support to run up to 140 partitions concurrently on

IBM p5 servers.

  1. It provides virtual I/O.
  2. It provides high speed communication between partitions using Virtual LAN.

What is Service Processor And How To Access It

The Service Processor provides the ability to view and change the power-on settings of running system. Service Processor also monitors the operating system to confirm that its running or hanged.

Introduction To HMC

HMC is a Linux based desktop PC workstation which is dedicated to a number of pSeries servers. It’s is used to manage LPARs. There can be several LPARs or a single full partition on physical pSeries server system…

Dynamically changing LPARs (Video)

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.

Create the first Logical Partition (LPAR) (Video)

So, I thought of bringing a video for you which can give you a live demonstratino video for you. Its about 10 minutes video which demonstrates how to create LPAR on IBM machines using HMC(Hardware Management Console)…

Create the first Logical Partition Video (LPAR)

Creating your first LPAR on the HMC with physical resources and boot it up and accessing the remote console.

Difference between LPAR and VIO Server

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

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

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