nPartitions in SIM
This chapter describes how SIM handles nPartitions in case of Integrity BL8x0c i4 blades.
Unpartitioned/default configuration
SIM treats the Unpartitioned Integrity BL8x0c i4 blades exactly in the same way as it does the
Integrity BL8x0c i2 blades .
Partitioned scenarios
Once the System Administrator changes the partition configuration successfully (either Scale up or
Scale down), the node structure in SIM will be updated on reception of traps from OA. SIM always
creates as many nodes as equal to the number of Monarchs present in a Blade Link Domain.
For example, when the partition configuration is AACC, two monarch nodes would be created
and when the partition configuration is ABCD, four monarch nodes will be created. Auxiliary nodes
are never created in SIM.
Discovery of partitions in SIM mainly depends on Model, Serial Number, UUID and NParID and
all of these parameters can be verified either from OA, iLO or WBEM Providers.

Nodes and associations
Upon successful discovery of the Monarchs, all the Monarch nodes in a Blade Link Domain are
associated to the corresponding Blade Link Domain Node. Since by definition, an nPartition
