IBM System Storage DS8000
The IBM System Storage DS8000® series is designed to manage a broad scope of storage
workloads that exist in today's complex data center, doing it effectively and efficiently. The
proven success of this flagship IBM disk system is a direct consequence of its extraordinary
flexibility, reliability, and performance, but also of its capacity to satisfy the needs of
continuous change. The latest evidence of DS8000 series value is the IBM System Storage
DS8870 as the ideal storage platform for enterprise class environments by providing unique
performance, availability, and scalability.
The DS8870 delivers the following features:
Up to three times higher performance compared to DS8800
Improved security with FDE as standard on all systems
Optimized Flash technology for dynamic performance and operational analytics
Additionally, the DS8000 includes a range of features that automate performance optimization
and application quality of service, and provides the highest levels of reliability and system
uptime. For more information, see the following website:

2.12 Hardware Management Console (HMC)

The HMC is a dedicated workstation that provides a graphical user interface (GUI) for
configuring, operating, and doing basic system tasks for the POWER7+ and POWER7
processor-based systems (and the POWER5, POWER5+, POWER6, and POWER6+
processor-based systems) that function in either non-partitioned or clustered environments.
In addition, the HMC is used to configure and manage partitions. One HMC is capable of
controlling multiple POWER5, POWER5+, POWER6, POWER6+, POWER7, and POWER7+
processor-based systems.
At the time of writing, the HMC must be running V7R7.6.0, It can also support up to 48
POWER7+ systems (non Power 590 and 595 models) or 32 IBM Power 590 and 595 servers.
The total number of LPARs is changing to 2000 from 1024 only if you have V7R7.6.0 and the
HMC is model 7042-CR6 or later. Updates of the machine code, HMC functions, and
hardware prerequisites, can be found on the Fix Central website:
http://www-933.ibm.com/support/fixcentral/
Sharing: An HMC is a mandatory requirement for the both the POWER7+ 770 and 780
systems, but it is possible to share an HMC with other Power systems.

2.12.1 HMC mode and RAID 1 support

The Hardware Management Console (HMC) is updating its underlying appliance hardware to
stay current with updates in hardware technology. The 7042-CR6 system is being replaced
with the 7042-CR7.
The IBM 7042-CR7 Hardware Management Console is a dedicated rack-mount workstation
that allows customers to configure and manage system resources on IBM Power Systems
