Desktop and mobile Architecture for System Hardware


Desktop and mobile Architecture for System Hardware

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:

  • DISCOVER
  • GET, PUT, CREATE and DELETE management resources, such as property values & settings
  • ENUMERATE for tables and collections
  • SUBSCRIBE to and DELETE events (indication delivery)
  • EXECUTE for services (method invocation)

DASH Management Access Point Discovery

Discovery of access points is a two phase process:

  • Phase 1: an RMCP Presence Ping request is sent (broadcast, multicast or unicast) and an RMCP Presence Pong response is received indicating support for WS-Management.
  • Phase 2: a WS-Management "Identify" request is sent and response is received indicating support for DASH, which version, and which security profiles.

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]:

Profile Support
Base Desktop and Mobile Mandatory
Profile Registration Mandatory
Role Based Authorization Mandatory
Simple Identity Management Mandatory
Battery Optional
BIOS Management Optional
Boot Control Optional
CPU Optional
