IBM Power 750 Technical Overview And Introduction page 110

The Power 750 and Power 760 platforms support two main service environments:
Attachment to one or more HMCs is a supported option by the system
This is the common configuration for servers supporting logical partitions with dedicated or
virtual I/O. In this case, all servers have at least one logical partition.
No HMC attachment
There are two service strategies for non-HMC attached systems:
– Full system partition: A single partition owns all the server resources and only one
operating system may be installed.
– Partitioned system: In this configuration, the system can have more than one partition
and can be running more than one operating system. In this environment, partitions
are managed by the Integrated Virtualization Manager (IVM), which includes some of
the functions offered by the HMC.
Hardware support for customer replaceable units is standard with the HMC. In addition you
have the option to upgrade this support level to IBM on-site support to be consistent with
other Power Systems servers.
If you want to use an existing HMC to manage any POWER7+ processor-based server, the
HMC must be a model CR3, or later, rack-mounted HMC, or model C05, or later, deskside
HMC. HMC V7R7.7.0 is the last release to be supported on models 7310-C04, 7315-CR2,
and 7310-CR2. Future HMC releases will not be supported on C04 or CR2 models.
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 a CR3 model, or later,
rack-mounted, or a C06, or later, deskside.
HMC code level
HMC V7R7.7.0 (SP1) contains the following new benefits:
Support for managing IBM Power 750 and Power 760 systems
Support for PowerVM functions such as new HMC GUI interface for VIOS install
Improved transition from IVM to HMC management
Ability to update a user password in Kerberos from the HMC for clients using remote HMC
HMC V7R7.7.0 (SP1) supports up to 48 servers (non Power 590, Power 595, and Power 795
models) or 32 IBM Power 590, Power 595, and Power 795 servers. A maximum of 2000
LPARs is supported when you use a HMC V7R7.6.0 code at a minimum level and the HMC is
a model 7042-CR6 or later.
If you attach an existing HMC to a new server such as the Power 750 and Power 760 or add
functions to an existing server that requires a firmware update, the HMC machine code might
need to be updated. You should upgrade the support level of the HMC to be consistent with
the support that is provided on the servers to which it is attached. In a dual HMC
configuration, both systems must be at the same version and release of the HMC.
To determine the HMC machine code level that is required for the firmware level on any
server, go to the following website to access Fix Central and the Fix Level Recommendation
Tool (FLRT) on or after the planned availability date for this product. FLRT will identify the
correct HMC machine code for the selected system firmware level.

With HMC code V7R7.7.0 (SP1), the HMC supports Mozilla Firefox 7 through 10 and
Microsoft Internet Explorer 7 through 9.
