- 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:
- 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
The DMTF CIM Profiles supported by the DASH 1.1 specification:
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 DHCP Client Optional DNS Client Optional Ethernet Port Optional Fan Optional Host LAN Network Port Optional Indications Optional IP Interface Optional KVM Redirection Optional Media Redirection Optional Opaque Management Data Optional OS Status Optional Physical Asset Optional Power State Management Optional Power Supply Optional Sensors Optional Software Inventory Optional Software Update Optional System Memory Optional Text Console Redirection Optional USB Redirection 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.
