In April 2007 the Desktop and Mobile Working Group (DMWG) of the DMTF started work on an implementation requirements specification (DSP0232). Version, DASH 1.1, was published in December 2007 and became a DMTF standard in June 2009. Version, DASH 1.2, was published in December 2014 and became standard in June 2015.
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 Common Information Model (CIM) schema defines the supported DASH management data and operations. There are 28 CIM profiles supported in the DASH 1.1 specification. 9 new profiles were added and 4 profiles were updated in DASH 1.2 specifications.
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)
Management access point discoveryEdit
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 management protocols layers include:

ProfilesEdit
The DMTF CIM Profiles supported by the DASH 1.1 specification:[1]
The DMTF CIM Profiles supported by the DASH 1.2 specification:[2]
DASH is designed for desktop and mobile computer systems; a related DMTF standard for management of server computer systems is the Systems Management Architecture for Server Hardware (SMASH), with a similar set of CIM Profiles.
Intel Active Management Technology is a compliant implementation of DASH.
IPMI -A server management interface standard covering similar functionality as DASH, but using a UDP-based protocol compared with the TCP/SOAP protocol of DASH. DASH can be implemented on top of IPMI.
