7、ires management 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 s
8、ub-optimal result. This 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 Standard acknowledges that those Resources may be composed of other Resources (
9、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 Standard models as Resource Components and groups into IT, power and fluid Domains, respectively. This 3rdedition is fully ali
10、gned with ISO/IEC 19395:2015. This Ecma Standard has been adopted by the General Assembly of June 2015. iv Ecma International 2015“COPYRIGHT NOTICE 2015 Ecma International This document may be copied, published and distributed to others, and certain derivative works of it may be prepared, copied, pu

Resources model IT and facility equipment, systems and components in a data centre. To monitor and control the Resources
18、Properties, Management Functions exchange command, response or event Messages with Resources, see Figure 1. g3Figure 1 Scope Resources are made up out of Resource Components which this second edition shares Properties with classes in Common Information Models (CIM). Messages refer to Resources and t
19、heir Properties. Messages are encoded in XML and exchanged in HTTP primitives. Figure 1 illustrates the functionality that this second edition adds as described above. g3Figure 2 Functionality that second edition adds Management Function(s), Resources, IT each received request requires a response as
20、 specified in DSP0200. A Management Function uses a CIM Listener and a CIM Client to send and receive Messages. Resources use a CIM Server, which implements the HTTP server, to send and receive Messages. Properties of a Resource are represented as Properties of an instance of a CIM class. Management
21、 Function shall have information of the instance name and the CIM Server that represents a Resource to query the properties of the Resource. To query Properties of a Resource, Management Functions shall include the corresponding instance name and the CIM Server that represents the Resource in CIM me
22、ssages. The CIM Server shall respond a CIM Ecma International 2015 23message request as a proxy for the Resource. Unimplemented Properties or Event Conditions shall be signalled in responses that carry “CIM_ERR_NO_SUCH_PROPERTY“ or “CIM_ERR_NOT_FOUND“ error codes respectively. 7.1 Commands and respo
23、nses 7.1.1 GET 7.1.1.1 GET command GET command specified in the table below shall be used to request Resource Properties or Event Descriptions. GET command shall be issued by Management Function and be received by Resource. Item Corresponding CIM-XML header Message type Request ID Object data Target

28、ndicationFilter as described in CIM Event Model White Paper (DSP0107). Management Function issues Event subscription request to Resources that register the Event subscriptions that may result in event notifications. In the table, “M” and “O” indicate a field is mandatory or optional respectively. Fi
