Show Device

Shows information about one or more Intel Optane DC memory modules.

ipmctl show [OPTIONS] -dimm [TARGETS]

Targets

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

• -socket (SocketIDs): Restricts output to the modules 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

List a few key fields for each persistent memory module.

$ sudo ipmctl show -dimm
