Regarding administration and operation, all MUs of the Management Cluster are equally
ranking. This means you can centrally administer and operate all objects of the whole SE
server configuration (in this case: two SE servers) from one MU.
The SE servers can be operated as long as one MU functions. However, an MU of the local
SE server is required for the SVP operation of an SU /390 and its correct HW display.
2.5.2 SU Cluster
Two Server Units of the same type (SU /390 or SU x86) can be combined into a logical unit,
a so-called "SU Cluster".
An SU Cluster is configured by Customer Support based on the customer's wishes and
provides the Live Migration (LM) function for the BS2000 systems of the two Server Units.
Live Migration is used to migrate a BS2000 system from the source SU to another SU
(target SU) of the same type and operating mode. This means that a running system can
be migrated to a target SU without interruption. A planned operational interruption, e.g. for
hardware maintenance, is therefore no longer required. LM can also be used for manual
load balancing, e.g. in the event of recurring high-load phases.
An SU Cluster with SU /390 is always cross-server and thus requires a Management
Cluster. An SU Cluster with SU x86 may also be configured locally on one server, in case
an SE server has more than one SU x86.
