DASH ("Desktop and mobile Architecture for System Hardware") is a DMTF standard on requirements for implementing the Desktop and Mobile Architecture for System Hardware.

DASH implementation requirements specification (DSP0232) was launched by the Desktop and Mobile Working Group (DMWG) of the DMTF in April 2007. The current version, DASH 1.1, was published in December 2007 and became a DMTF standard in June 2009.

In-service and out-of-service systems can be managed, with manageability aligned between the modes, independent of operating system state. Both HTTP and HTTPS management ports are supported: TCP ports 623 and 664, respectively, for connections from remote management consoles to DASH out-of-band management access points (MAP).

The DMTF CIM schema defines the supported DASH management data and operations. There are currently 28 CIM profiles supported in the DASH 1.1 specification.

DASH uses the DMTF's Web Services for Management (WS-Management) protocol for communication of CIM objects and services.

The web services expose a common set of operations for system management:

DASH management access point discovery

Discovery of access points is a two phase process:

DASH protocol stack

The layered DASH management protocol stack:

Layer Type
DASH Management Service App
DASH CIM Profiles App
WS-Management CIM Binding App
Data Transfer (WS-Eventing, WS-Enum, WS-Transfer, WS-Addressing) WS Layer
Security Profiles WS Layer
Simple Object Access Protocol (SOAP) / XML SOAP
HTTP/TLS SOAP
TCP SOAP
IP Network
MAC/PHY Network

DASH profiles

The DMTF CIM Profiles supported by the DASH 1.1 specification:[1]

Role Based Authorization Mandatory
Simple Identity Management Mandatory
Battery Optional
BIOS Management Optional
Boot Control Optional
CPU Optional
DHCP Client Optional
DNS Client Optional

As DASH is designed for desktop and mobile computer systems, a related DMTF standard for management of server computer systems also exists: Systems Management Architecture for Server Hardware (SMASH), with a similar set of CIM Profiles.

Intel Active Management Technology (AMT) is a compliant implementation of DASH.
