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.

Examples

Display all DDR and Optane persistent memory modules installed in the system

$ ipmctl show -topology
