Hmc Connectivity To The Power7+ Processor-Based Systems - IBM Power 750 Technical Overview And Introduction

HMC RAID 1 support
HMCs now offer a high-availability feature. Starting from HMC 7042-CR7 RAID 1 protection
will be enabled by default. This feature enables data redundancy using two physical disk
drives.
RAID 1 is also offered on both the 7042-CR6 and the 7042-CR7 (if the feature was removed
from the initial order) as an MES upgrade option.
Blade management
The HMC gives systems administrators a tool for planning, virtualizing, deploying, and
managing IBM Power System servers.
With the introduction of HMC V7R760, the HMC can now manage IBM BladeCenter Power
Blade servers. This management includes support for dual VIOS, live partition mobility
between blades and rack servers, and management of both blades and rack servers from a
single management console.
Comparison of 7042-CR6 and 7042-CR7 HMC models
The 7042-CR6 was withdrawn from marketing in December 2012. For your reference,
Table 2-29 compares the 7042-CR6 and the 7042-CR7 HMC models.

2.11.1 HMC connectivity to the POWER7+ processor-based systems

POWER7+ processor technology-based servers and also their predecessor systems that are
managed by an HMC require Ethernet connectivity between the HMC and the server's
service processor. In addition, if dynamic LPAR, Live Partition Mobility, or PowerVM Active
Memory Sharing operations are required on the managed partitions, Ethernet connectivity is
needed between these partitions and the HMC. A minimum of two Ethernet ports are needed
on the HMC to provide such connectivity.
For any logical partition in a server it is possible to use a Shared Ethernet Adapter that is
configured through a Virtual I/O Server. Therefore, a partition does not require its own
physical adapter to communicate with an HMC.
