28 IBM Power 770 and 780 (9117-MMD, 9179-MHD) Technical Overview and Introduction
The Power 770 and Power 780 support only the SAS DASD SFF hard disks, internally. The
existing 3.5-inch DASD hard disks can be attached to Power 770 and Power 780, but must be
located in an I/O drawer such as FC 5886.
For POWER6, POWER6+, or POWER7 processor-based systems that have the On/Off CoD
function enabled, you must reorder the on/off enablement features (FC 7951and FC 7954)
when placing the upgrade MES order for the new Power 770 or 780 system to keep the
On/Off CoD function active. To initiate the model upgrade, the on/off enablement features
should be removed from the configuration file before the MES order is started. Any temporary
use of processors or memory owed to IBM on the existing system must be paid before
installing the Power 770 model MMD or Power 780 model MHD.
Features FC 8FC 8018 and FC 8030 are available to support migration of the PowerVM
features FC 7942 or FC 7995 during the initial order and build of the MMD or MHD upgrade
MES order. Customers can add feature FC 8018 or FC 8030 to their upgrade orders in a
quantity not to exceed the quantity of feature FC 7942 or FC 7995, obtained for the system
being upgraded. Feature FC 7942 or FC 7995 must be migrated to the new configuration
report in a quantity that equals feature FC 8018 or FC 8030. Additional FC 7942 or FC 7995
features can be ordered during the upgrade.
Clients can add feature FC 8018 to their upgrade orders in a quantity not to exceed the
quantity of feature FC 7942, obtained for the system being upgraded. Feature FC 7942 must
be migrated to the new configuration report in a quantity that equals feature FC 8018.
Additional FC 7942 features can be ordered during the upgrade.
Features 8527 and 8528 are available to support migration of DDR3 memory activations 1812
or 1813 during the initial order and build of the MHD upgrade MES order. You can add
features 8527 and 8528 to your upgrade orders in a quantity not to exceed the quantity of
feature 1812 or 1813 obtained for the system being upgraded. The 1812 or 1813 features
should be migrated to the new configuration report in a quantity that equals feature 1812 and
1813. Additional 1812 or 1813 features can be ordered during the upgrade.
1.11 Management consoles
This section discusses the supported management interfaces for the servers.
1.11.1 HMC models
The Hardware Management Console (HMC) is required for managing the IBM Power 770 and
Power 780. It has a set of functions that are necessary to manage the system:
Creating and maintaining a multiple partition environment
Displaying a virtual operating system session terminal for each partition
Displaying a virtual operator panel of contents for each partition
Detecting, reporting, and storing changes in hardware conditions
Powering managed systems on and off
Acting as a service focal point for service representatives to determine an appropriate
service strategy
In 2012, IBM announced a new HMC model, machine type 7042-CR7. Hardware features on
the CR7 model include a second HDD (FC 1998) for RAID 1 data mirroring, and the option of
a redundant power supply. At the time of writing, the latest version of HMC code was V7.6.0.
