Show Topology

Shows the topology of DDR and persistent memory modules installed in the host server.

ipmctl show [OPTIONS] -topology [TARGETS]

Targets

• -dimm [(DimmIDs)]: Restricts output to specific DIMMs by optionally supplying the DIMM target and one or more comma-separated DIMM identifiers. The default is to display all DIMMs.

• -socket (SocketIDs): Restricts output to the DIMMs installed on specific sockets by supplying the socket target and one or more comma-separated socket identifiers. The default is to display all sockets.

  • If ACPI PMTT table is not present, then DDR4 memory will not be displayed in the filtered socket list.

Example

$ ipmctl show -topology
