Nationa
13、l bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. O
14、ther international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intend
15、ed for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.or
16、g/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document
17、 will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

20、of storage, computation, communication, electrical energy and temperature to achieve the required quality of service and efficiency parameters. Often, however, the separate management of Information Technology (IT), electrical energy (or power) and cooling Resource islands yields a sub-optimal resul
21、t. This International Standard provides Messages that facilitate integrated or “smart” monitoring and control of Resources in those islands. The Messages are exchanged between the Management Function and Resources. The International Standard acknowledges that those Resources may be composed of other
22、 Resources (e.g. a rack may contain servers, ventilators, etc.). In addition, e.g. those servers may be viewed from their computing, energy consumption or dissipation aspects which this International Standard models as Resource Components and groups into IT, power and fluid Domains, respectively.

Resources model IT
24、 and facility equipment, systems and components in a data centre. To monitor and control the Resources Properties, Management Functions exchange command, response or event Messages with Resources, see Figure 1. Figure 1 Scope Resources are made up out of Resource Components which this second edition
25、 shares Properties with classes in Common Information Models (CIM). Messages refer to Resources and their Properties. Messages are encoded in XML and exchanged in HTTP primitives. Figure 1 illustrates the functionality that this second edition adds as described above. Figure 2 Functionality that sec
26、ond edition adds Management Function(s), Resources, IT & facility equipment, systems and components themselves are out of scope as illustrated in Figure 1, Figure 2 and Figure 3.
