Examples of CMIC Collectives in a System with Multiple Cabinets
![]()
- In a system, cabinets in the server management network are organized into collectives.The system number, collective numbers, and cabinet numbers are viewable in SMWeb Services web applications.
- Depending on your system configuration, a system has one or more collectives.
- A CMIC VM provides server management services for a collective, with one or more cabinets per collective. One cabinet in a collective must contain a CMIC VM hosted by a VMS.
In single-system and multi-system configurations, each CMIC VM in the VMS can manage a maximum of 50 nodes and servers running CMIC 11.04 or later. The base cabinet contains a system VMS with a CMIC VM. The first expansion cabinet contains a cabinet VMS with a CMIC VM. The number of additional expansion cabinets with a cabinet VMS depends on the number of nodes the CMIC VM is expected to manage. For systems with more than 648 nodes, two of the 1800 cabinets have subnet manager servers.
- The following cabinets can be configured with or without a CMIC VM hosted by a VMS: processing/storage cabinet, BYNET V5 InfiniBand switch cabinet, or Platform Framework Cabinet (PFC).
- A collective can contain one or more of the following cabinets. At least one of the cabinets must contain a CMIC VM hosted by a VMS.
- Processing/storage cabinet
- BYNET V5 cabinet (if used)
- PFC (if used)
- Each collective in the system has a unique collective ID (collective number).
- Each cabinet in the system has a unique cabinet ID (cabinet number).
- Collectives and cabinets are numbered as follows:
- Collectives are numbered consecutively, beginning with Collective 1.
- Cabinets are numbered consecutively, beginning with Cabinet 1.
- In the collectives shown:
- Collective 1 contains one cabinet (Cabinet 1) managed by one CMIC VM hosted by a VMS in the cabinet.
- Collective 2 contains two cabinets (Cabinet 2 and Cabinet 3). Both cabinets are managed by one CMIC VM hosted by a VMS in Cabinet 2.
