IBM System p5 520 and 520Q Technical Overview and Introduction
1.3.6 Hardware Management Console models
A p5-520 or p5-520Q can be either HMC-managed or non-HMC-managed. In HMC-managed
mode, an HMC is required as a dedicated workstation that allows you to configure and
manage partitions. The HMC provides a set of functions to manage the 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.

Systems require Ethernet connectivity between HMC and one of the Ethernet ports of the
service processor. Ensure that sufficient HMC Ethernet ports are available to enable public
and private networks if you need both. The 7310 Model C05 is a deskside model with one
native 10/100/1000 Ethernet port. It can be extended with two additional two-port
10/100/1000 Gb adapters. The 7310 Model CR3 is a 1U, 19-inch rack mountable drawer 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, you should
consider deployment of two HMCs. The service processor allows for connection of two HMCs,
and there is no need for special handling of a dual HMC environment. HMCs provide a locking
mechanism so that only one HMC has write access to the service processor at a time.

When an HMC is connected to the system, the integrated system ports are disabled.
To support a non-Ethernet HACMP™ heartbeat, you need to provide an asynchronous

Note: The 7311 Model D20 I/O drawer is designed to be installed by an IBM service
representative. Only the 7311 Model D20 I/O drawer is supported on a p5-520 or p5-520Q
system.

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 57.
