1.3.7 Hardware Management Console (HMC) models
The p5-550 or p5-550Q can be HMC managed or non-HMC managed. In HMC managed
mode, an HMC is recommended as a dedicated workstation that allows you to configure and
manage partitions. The HMC provides a set of functions to manage the p5-550 or p5-550Q
system LPARs, dynamic LPAR operations, virtual features, Capacity on Demand, inventory
and microcode management, and remote power control functions. These functions also
include the handling of the partition profiles that define the processor, memory, and I/O
resources allocated to an individual partition. For detailed information about the HMC, see
2.13, “Hardware Management Console” on page 60.
Table 1-12 lists the HMC options for POWER5™ and processor-based systems
available at the time of writing. You can also use existing HMC models.
Table 1-12 Available HMCs
Systems require Ethernet connectivity between the HMC and one of the Ethernet ports of the
service processor. Ensure that sufficient Ethernet adapters are available to enable public and
private networks if you need both. The 7310-C05 is a deskside model with one native
10/100/1000 Ethernet port. Two additional two-port 10/100/1000 Gb adapters can be added
to the 7310-C05. The 7310-CR3 is a 1U, 19-inch rack mountable model that has two native
Ethernet ports and can be extended with one additional two-port 10/100/1000 Gb adapter.
In HMC managed installations with very high demand for high availability, deployment of two
HMCs should be considered. The service processor allows for connection of two HMCs; there
is no need for special handling of such dual HMC environment. HMCs provide a locking
mechanism so that only one HMC at a time has write access to a service processor.
When an HMC is connected, the p5-550 or p5-550Q integrated system serial ports are
disabled. If you need serial connections, for example, non-Ethernet HACMP™ heartbeat, you
need to provide an additional Async adapter (FC 5723 or FC 2943).
p5-550 or p5-550Q Max number of I/O drawers Total number of PCI-X slots
One additional FC 1806 Four 28 + 4 (excluding used slots)
Two additional FC 1806 Eight 56 + 3 (excluding used slots)
Note: Non-HMC-managed modes are full system partition modes, where only one partition
contains all system resources that exist on the system. For more information about using
the Integrated Virtualization Manager (IVM), see 2.12.5, “Integrated Virtualization
Manager” on page 58.

Note: It is not possible to connect POWER4™ and POWER5, or POWER4 and
processor-based systems simultaneously to the same HMC. It is possible to connect
POWER5 and processor-based systems together to the same HMC.
