Ivm - IBM BladeCenter PS700 Technical Overview And Introduction

2.11 IVM

IVM is a simplified hardware management solution that is part of the PowerVM
implementation on the PS700, PS701, and PS702 blades. POWER processor-based blades
do not include an option for attachment to a Hardware Management Console (HMC).
IVM inherits most of the HMC features and capabilities and enables the exploitation of
PowerVM technology. It manages a single server, avoiding the need for an independent
appliance. It is designed to provide a solution that enables the administrator to reduce system
setup time and to make hardware management easier, at a lower cost.
IVM is an addition to the Virtual I/O Server, the product that enables I/O virtualization in the
family of POWER processor-based systems. The IVM functions are provided by software
executing within the Virtual I/O Server partition installed on the server to manage. See
Table 2-9.
For a complete description of the possibilities offered by IVM, see Integrated Virtualization
Manager on IBM System p5, REDP-4061, available the following Web page:
