IBM Power Systems E870 and E880 Technical Overview and Introduction
Figure 2-40 shows one possible highly available HMC configuration that is managing two
servers. Each HMC is connected to one FSP port of each managed server.
Figure 2-40 Highly available HMC networking example
For simplicity, only the hardware management networks (LAN1 and LAN2) are highly
available (Figure 2-40). However, the open network (LAN3) can be made highly available by
using a similar concept and adding a second network between the partitions and HMCs.
For more information about redundant HMCs, see IBM Power Systems HMC Implementation
and Usage Guide, SG24-7491.
2.12 Operating system support
The IBM Power E870 and Power E880 systems support the following operating systems:
AIX
IBM i
Linux
In addition, the Virtual I/O Server can be installed in special partitions that provide support to
the other operating systems for using features such as virtualized I/O devices, PowerVM Live
Partition Mobility, or PowerVM Active Memory Sharing.
