Managing groups of servers

A central management system comprising:

• a processor;
• a monitoring module coupled to the processor to:
• monitor status of at least one of servers in a group and network links between the servers for identifying an event, each server in the group being accessible by a common access credential, and the event being associated with at least one of a change in a layout of servers in the group and a change in interconnection between servers in the group;
• a topology module coupled to the processor to:
• update, in response to occurrence of the event, a node topology map, corresponding to a topology characteristic;
• determine at least one affected server from the servers in the group based on the updated node topology map, the at least one affected server having a changed interconnection or a new interconnection with another server in the group;
• and
• transmit the updated node topology map to the at least one affected server in the group, the node topology map being transmitted by a unicast message.

A non-transitory computer-readable medium comprising instructions executable by a processing resource to:

• assign an identified server to a group, the assigning being based on analysis of grouping information associated with the identified server, the grouping information including an access credential associated with the identified server, and each server in the group being accessible by a common access credential;
• generate a plurality of node topology maps corresponding to the group, the generating being based on a set of topology characteristics, and the plurality including a node topology map that corresponds to a topology characteristic that indicates a layout of servers in the group, and that indicates an interconnection between the servers;
• select a node topology map from the plurality of node topology maps based on characteristics of an operation, the operation is to be executed on at least one server in the group;
• and
• communicate a message to a server corresponding to the selected node topology map, the message including an instruction for executing the operation.
