Examples of CMIC Collectives in a System with Multiple Cabinets
- In a system, cabinets in the server management network are organized into collectives.
- Depending on your system configuration, a system has one or more collectives, and a collective can contain one or more cabinets.
- A collective contains one or more cabinets having/sharing one CMIC VM hosted by a VMS.
- The following cabinets can be configured with or without a CMIC VM hosted by a VMS: processing/storage cabinet, InfiniBand switch cabinet, or Platform Framework Cabinet (PFC).
- A collective can contain one or more of the following cabinets:
- Processing/storage cabinet. Each processing/storage cabinet must be in a separate collective. The collective, cabinet, and node chassis ID number combination must be unique. For example, using the notation SystemID#.CollectiveID#.CabinetID#.ChassisID#, in a system with two nodes, the following IDs are valid for the nodes: 1.1.1.1 and 1.2.1.1 (although the ChassisID=1 for both nodes, for one node the CollectiveID=1 and for the other node the CollectiveID=2); however, the IDs 1.1.1.1 and 1.1.2.1 are not valid because for both nodes the CollectiveID=1 and the ChassisID=1.
- InfiniBand cabinet (if used)
- PFC (if used). If the PFC cabinet contains a channel server, the PFC cabinet must be in a separate collective and the collective and cabinet number combination must be unique.
- If the system contains an InfiniBand or PFC cabinet that does not contain a CMIC VM hosted by a VMS, the InfiniBand or PFC cabinet must be assigned to a collective that contains a processing/storage cabinet with a CMIC VM hosted by a VMS.
- Collectives and cabinets are numbered as follows:
- Collectives are numbered consecutively, beginning with Collective 1.
- Cabinets in a collective are numbered consecutively, beginning with Cabinet 1.
- Each collective shown in the examples above contains one appliance cabinet. Each cabinet is managed by one CMIC VM hosted by a VMS in the cabinet.
- A collective can have a maximum 32 cabinets in a Class A network; maximum 16 in a Class B network.
