Standard built-in, independent component of every eServer i5 or p5

Own processor, memory and boot code

NVRAM stores the “firmware” and the LPAR configuration

The Service Processor (aka SP)

Once main power is connected ...

The SP activates its own “firmware” operating system

Control panel shows C1xx progress codes

Gathers vital product data (VPD) from the electronic components in the server

Runs diagnostic routines to verify its hardware and firmware

Control panel shows 01 and the green power LED is flashing

The server is in “SP Standby” mode

The server is ready to interface with HMC

The SP turns on the system power

All I/O towers via SPCN

Control panel shows C7xx progress codes

Runs diagnostic routines to verify system processors and system main storage

Verifies that it can communicate with environmental sensors and monitors in the system

Architecture

The Power Hypervisor

Previously part of the System Licensed Internal Code (SLIC)

Known as “Partition Licensed Internal Code (PLIC)”

PLIC is enhanced to be used with the eServer i5 hardware

Power Hypervisor is independent from any operating system

There is no longer the concept of a “Primary Partition”

There is no longer the need to IPL the whole system to make partitions changes

There is no longer a single point of failure with a “Primary Partition”

Resources Management Concepts

iSeries. mySeries.

Resources Management Concepts

What is “logical partitioning” ?

The ability to make a single server run as if it were many independent systems

Each logical system is called a “Partition”

Each partition operates as an independent system

Each partition will receive a portion of the system resources :

Processor

Memory

I/O slots

Virtual I/O slots

Processor Concepts

Dedicated Processors

A “dedicated processor” refers to a whole processor that is dedicated to a single partition

One or more processors can be dedicated to a partition

The most simple way to distribute processors among logical partitions

Rules & requirements :

At least one dedicated processor

Granularity of movements : one processor

Processor moves are dynamic, without any IPL within the configured ranges

Unallocated processors are not used
