(DMTF) standard.

Description

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

DASH management protocols layers include:

Profiles

The DMTF CIM Profiles supported by the DASH 1.1 specification: The DMTF CIM Profiles supported by the DASH 1.2 specification:"DASH 1.2 Implementation Requirements"
/ref> 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.
