Additionally, the DS8000® includes a range of features that automate performance
optimization and application quality of service, and also provide the highest levels of reliability
and system uptime. For more information, see the following website:

2.9 Hardware Management Console (HMC)
The Hardware Management Console (HMC) is a dedicated appliance that allows
administrators to configure and manage system resources on IBM Power Systems servers
that use IBM POWER6, POWER6+ POWER7, POWER7+, and POWER8 processors. The
HMC provides basic virtualization management support for configuring logical partitions
(LPARs) and dynamic resource allocation, including processor and memory settings for
selected Power Systems servers. The HMC also supports advanced service functions,
including guided repair and verify, concurrent firmware updates for managed systems, and
around-the-clock error reporting through IBM Electronic Service Agent™ for faster support.
The HMC management features help to improve server utilization, simplify systems
management, and accelerate provisioning of server resources using the PowerVM
virtualization technology.
The Power S822 platforms support two main service environments:
򐂰 Attachment to one or more HMCs
– This environment is the common configuration for servers supporting logical partitions
with dedicated or virtual I/O. In this case, all servers have at least one logical partition.
򐂰 No HMC attachment
Systems not attached to an HMC will fall under one of two service strategies:
– Full system partition: A single partition owns all the server resources and only one
operating system may be installed.
– Partitioned system: The system has more than one partition, and the partitions can be
running different operating systems. In this environment, partitions are managed by the
Integrated Virtualization Manager (IVM), which includes some of the functions offered
by the HMC.
Hardware support for customer-replaceable units comes standard along with the HMC. In
addition, users have the option to upgrade this support level to IBM on-site support to be
consistent with other Power Systems servers.
2.9.1 HMC code level
HMC V8R8.1.0 contains the following new features:
򐂰 Support for managing the IBM Power System S812L, S814, S822, S822L, and S824
servers
򐂰 Support for the new HMC model 7042-CR8
Requirements: When using the HMC with the Power S822 servers, the HMC code must
be running at V8R8.1.0 level, or later.
