IBM Power System E850C: Technical Overview and Introduction
2.13 Hardware Management Console
The Power E850C platforms support two main service environments:
One or more HMCs:
This is a supported option by the system with PowerVM. 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:
There are two service strategies for non-HMC systems:
– Full-system partition with PowerVM: A single partition owns all the server resources
and only one operating system may be installed.
– Partitioned system with PowerVM: In this configuration, the system can have up to
three partitions and can be running more than one operating system. In this
environment, partitions are managed by the Integrated Virtualization Manager (IVM),
which provides some of the functions that are provided by the HMC.
For more information about IVM, see
Integrated Virtualization Manager for IBM Power
Systems Servers, REDP-4061.
An HMC is a dedicated appliance that allows administrators to configure and manage system
resources on IBM Power Systems servers that use IBM POWER6, POWER7,
, and POWER8 processors and the PowerVM Hypervisor. 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 verification, 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 improve server usage, simplify systems management,
and accelerate provisioning of server resources by using the PowerVM virtualization
technology.
The HMC could either be a hardware or a virtual appliance, which are described in more
detail in the next sections. You can use Power Systems HMCs in any of the following
configurations:
Only hardware appliance HMCs
Only virtual appliance HMCs
A combination of hardware appliance and virtual appliance HMCs
2.13.1 Hardware appliance HMC
The 7042-CR9 hardware appliance HMC is a dedicated rack-mounted workstation that can
be used to manage any of the systems that are supported by the version 8 HMC. It provides
hardware, service, and basic virtualization management for your Power Systems servers.
Requirements:
When using any HMC with the Power E850C, the HMC code must be running at
V860.10 level or later. The minimum firmware level for the Power E850C is V860.10 or
later.
When using the Power E850C server to access the cloud-based HMC Apps as a
Service, the HMC code must be at a minimum level of V860.
