Distributed Management Task Force (DMTF) standards enable effective management of IT environments. The organization is composed of companies that collaborate on the development, validation and promotion of infrastructure management standards. DMTF management standards are critical to enabling interoperability among multi-vendor systems, tools and solutions within the enterprise.

Overview

The DMTF is an industry standards organization working to simplify the manageability of network-accessible technologies through open and collaborative efforts by leading technology companies. DMTF creates and drives the international adoption of interoperable management standards, supporting implementations that enable the management of diverse traditional and emerging technologies including cloud, virtualization, network and infrastructure.

DMTF spans the globe with member companies and organizations representing varied industry sectors. The DMTF board of directors is led by 14 industry-leading technology companies including: Broadcom Limited, CA Technologies, Dell, Emerson Network Power, Hewlett Packard Enterprise, Hitachi, Ltd., HP Inc., Intel Corporation, Lenovo, Microsoft Corporation, NetApp, Software AG, TIM and VMware.

Supporting implementations that enable the management of diverse traditional and emerging technologies – including cloud, virtualization, network and infrastructure – the DMTF works to simplify the manageability of network-accessible technologies through open and collaborative efforts by leading technology companies.^[1]

Standards

DMTF standards include:

• Cloud Infrastructure Management Interface (CIMI) – a self-service interface for infrastructure clouds, allowing users to dynamically provision, configure and administer their cloud usage with a high-level interface that greatly simplifies cloud systems management. The specification standardizes interactions between cloud environments to achieve interoperable cloud infrastructure management between service providers and their consumers and developers, enabling users to manage their cloud infrastructure use easily and without complexity.
• Common Information Model (CIM) – the CIM schema is a conceptual schema that defines how the managed elements in an IT environment (for instance computers or storage area networks) are represented as a common set of objects and relationships between them. CIM is extensible in order to allow product specific extensions to the common definition of these managed elements. CIM uses a model based upon UML to define the CIM Schema. CIM is the basis for most of the other DMTF standards.
• Common Diagnostic Model (CDM) – the CDM schema is a part of the CIM schema that defines how system diagnostics should be incorporated into the management infrastructure.
• Web-Based Enterprise Management (WBEM) – defines protocols for the interaction between systems management infrastructure components implementing CIM, a concept of DMTF management profiles, that allows defining the behavior of the elements defined in the CIM schema, the CIM Query Language (CQL) and other specifications needed for the interoperability of CIM infrastructure.
• Systems Management Architecture for Server Hardware (SMASH) – a DMTF Management Initiative that include management profiles for server hardware management. SMASH 2.0 allows for either WS-Management or SM-CLP (a command line protocol for interacting with CIM infrastructure). SM-CLP was adopted as an International Standard in August 2011 by the Joint Technical Committee 1 (JTC 1) of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).^[2]
• System Management BIOS (SMBIOS) – defines how the BIOS interface of x86 architecture systems is represented in CIM (and DMI).
• Alert Standard Format (ASF) – defines remote control and alerting interfaces for OS-absent environments (for instance a system board controller of a PC).
• Desktop Management Interface (DMI) – the first desktop management standard. Due to the rapid advancement of DMTF technologies, such as CIM, the DMTF defined an "end of life" process for DMI, which ended March 31, 2005.
• Redfish – DMTF's Redfish API is an open industry standard specification and schema designed to meet the expectations of end users for simple, modern and secure management of scalable platform hardware. Created by the Scalable Platforms Management Forum (SPMF), Redfish specifies a RESTful interface and utilizes JSON and OData to help customers integrate solutions within their existing tool chains.
• Web Services Management (WS-MAN) – The DMTF’s Web Services Management (WS-Man) provides interoperability between management applications and managed resources, and identifies a core set of web service specifications and usage requirements that expose a common set of operations central to all systems management.A SOAP-based protocol for managing computer systems (e.g., personal computers, workstations, servers, smart devices), WS-Man supports web services and helps constellations of computer systems and network-based services collaborate seamlessly.
• Desktop and mobile Architecture for System Hardware (DASH) – a management standard based on DMTF Web Services for Management (WS-Management), for desktop and mobile client systems. WS-Management was adopted as an international standard by ISO/IEC in 2013.^[3]
• Configuration Management Database Federation (CMDBf) – facilitates the sharing of information between configuration management databases (CMDBs) and other management data repositories (MDRs). The CMDBf standard enables organizations to federate and access information from complex, multi-vendor infrastructures, simplifying the process of managing related configuration data stored in multiple CMDBs and MDRs.
• The Cloud Auditing Data Federation (CADF) – The Cloud Auditing Data Federation (CADF) standard defines a full event model anyone can use to fill in the essential data needed to certify, self-manage and self-audit application security in cloud environments. CADF is an open standard that addresses this need by enabling cross-vendor information sharing via its data format and interface definitions.
• Platform Management Components Intercommunication (PMCI) – a suite of specifications defining a common architecture for intercommunication among management subsystem components. This suite includes MCTP, PLDM and NC-SI specifications. The Platform Management standard was adopted as a national standard by ANSI in 2013.^[3]
• Virtualization Management Initiative (VMAN) – a suite of specifications based on DMTF’s CIM that helps IT managers: Deploy virtual computer systems, Discover/inventory virtual computer systems, Manage lifecycle of virtual computer systems, Create/modify/delete virtual resources and Monitor virtual systems for health and performance. VMAN was adopted as a National Standard by the American National Standards Institute (ANSI) International Committee for Information Technology Standards (INCITS) in June 2012.^[4]
• The Network Management Initiative (NETMAN) – addresses today’s complex data center and network environments. The initiative will lead the industry toward the unification of network management across traditional, cloud and software defined data center (SDDC) environments with the development of integrated standards to address physical, virtual, application-centric and software defined networks. While cloud, virtualization and software defined networking have eased the use of network functions for consumers, the challenges of deploying and managing the network supporting these infrastructures have magnified. Addressing the current complexity and abstraction, DMTF’s NETMAN will provide the necessary standards-based management models and interfaces to enable consistent, unified and automated provisioning, deployment, configuration, and monitoring of network environments.

Within the VMAN initiative, there are several specifications and profiles:

• Open Virtualization Format (OVF) – a standard for packaging and deploying virtual appliances. OVF was adopted by the American National Standards Institute in August 2010.^[5] OVF was adopted as an International Standard in August 2011 by the Joint Technical Committee 1 (JTC 1) of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).^[2] In January 2013, DMTF released the second version of the standard, OVF 2.0 which applies to emerging cloud use cases and provides important developments from OVF 1.0 including improved network configuration support and package encryption capabilities for safe delivery.
• DSP1042 – System Virtualization Profile
• DSP1057 – Virtual System Profile
• DSP1059 – Generic Device Resource Virtualization Profile
• DSP1041 – Resource Allocation Profile
• DSP1043 – Allocation Capabilities Profile

CIM related standards are also developed outside of the DMTF. Some examples are:

• The SNIA – develops and maintains the SMI-S standard that defines DMTF management profiles for Storage Area Networks.
• The Open Group – develops and maintains the CMPI standard that defines a C/C++ API for CIM providers.
• The Java Community Process – currently develops the JSR-48 standard that defines a Java API for CIM client applications.

CIM and WBEM are supported by a large number of products and open source projects. A small list is provided here:

• Windows Management Instrumentation (WMI) – an implementation of CIM and WBEM in Microsoft Windows
• WS (WBEM Solutions) – provides WBEM infrastructure and tools
• SBLIM – an open-source project providing an implementation of CIM and WBEM for Linux as well as other CIM and WBEM related components and tools
• OpenPegasus – an open-source project providing a CIM Object Manager written in C++ (the central infrastructure component for CIM and WBEM)
• WBEM Services – an open-source project providing a CIM Object Manager written in Java
• OpenWBEM – an open-source project providing another CIM Object Manager written in C++

Incubators and work groups

• Open Cloud Standards Incubator.^[6] The Open Cloud Standards Incubator was a DMTF group focused on standards for facilitating management interoperability between private clouds within enterprises and between private, public and hybrid clouds. Initial priorities include cloud resource management protocols, packaging formats and security mechanisms to help enable interoperability. The group developed a set of documents. The group completed its chartered deliverables in August 2010.^[7] DMTF's cloud standards development work is now being handled by the Cloud Management Workgroup,^[8] the Cloud Auditing Data Federation Workgroup^[9] and the System Virtualization, Partitioning, and Clustering Work Group.^[10]
• Software Entitlement Working Group (SEWG).^[11] The Software Entitlement Working Group is working to develop white papers which focus on challenges to enabling the industry to manage licensed software products and product use. The SEWG employs key leaders in the IT management space, and also has representation from end user organizations such as JP Morgan Chase. The group developed a whitepaper titled "Software Identification and Entitlement Usage Metrics",^[12] completed in 2012. This white paper describes a representative set of use cases for cloud, data center, virtualization, and on-premises needs. It also provides recommendations on technology standards to consider to sufficiently identify licensed software products, and to trace and gather the use of the software and other entitlement usage metrics across the span of deployments.
