Hardware Management Console and Support Elements
All z990 models include a Hardware Management Console (HMC) and two internal Support
Elements (SEs) that are located in the Z frame.
On z990 servers, the Hardware Management Console provides the platform and user
interface that can control and monitor the status of the system. The SEs are basically used by
IBM service representatives.
Up to four Hardware Management Consoles can be ordered per z990 server, providing more
flexibility and additional points of control. The Hardware Management Console can also
provide a single point of control and single system image for a number of CPCs configured to
it.
The internal SEs for each CPC are attached by local area network (LAN) to the Hardware
Management Console, and allow the Hardware Management Console to monitor the CPC by
providing status information. Each internal SE provides the Hardware Management Console
with operator controls for its associated CPC, so you can target operations in parallel to
multiple or all CPCs, or to a single CPC.
The second SE, called Alternate SE, is standard on all z990 models and serves as a backup
to the primary SE. Error detection and automatic switch-over between the two redundant SEs
provides enhanced reliability and availability. There are also two fully redundant interfaces,
known as the Power Service Control Network (PSCN), between the two SEs and the CPC.
