IBM Power 780 User Manual

106 IBM Power 770 and 780 (9117-MMD, 9179-MHD) Technical Overview and Introduction
When IBM Systems Director is used to manage an HMC or if the HMC manages more than
254 partitions, the HMC should have 3 GB of RAM minimum and be CR3 model, or later,
rack-mounted, or C06, or later, deskside.
With the release of V7R760, the HMC now supports Mozilla Firefox 7 through 10 and
Microsoft Internet Explorer 7 through 9.
HMC V7R760 is the last release to be supported on models 7310-C04,3 7315-CR2, and
7310-CR2. Future HMC releases will not be supported on C04 or CR2.
2.12.4 HMC connectivity to the POWER7+ processor-based systems
POWER5, POWER5+, POWER6, POWER6+, POWER7, and POWER7+ processor
technology-based servers 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. The
rack-mounted 7042-CR5 HMC default configuration provides four Ethernet ports. The
deskside 7042-C07 HMC standard configuration offers only one Ethernet port. Be sure to
order an optional PCIe adapter to provide additional Ethernet ports.
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.
For the HMC to communicate properly with the managed server, eth0 of the HMC must be
connected to either the HMC1 or HMC2 ports of the managed server, although other network
configurations are possible. You can attach a second HMC to HMC Port 2 of the server for
redundancy (or vice versa). These must be addressed by two separate subnets. Figure 2-37
shows a simple network configuration to enable the connection from HMC to server and to
enable dynamic LPAR operations. For more details about HMC and the possible network
connections, see Hardware Management Console V7 Handbook, SG24-7491.
