41、ecommunications physical environment to support NFV deployment. The intent is to develop a reference that enables compatibility between hardware equipment provided by different hardware vendors and suppliers. The environment in which NFV hardware will be deployed is taken into consideration for deve
42、loping this reference. Telecommunications Service Providers currently have the following hardware office environments: Central Office Access Node Transport Node Data Centre Hybrids (e.g. Central Office partitioned into or converted to a Data Centre) It is expected that the bulk of the NFV environmen
43、t will be deployed in Data Centres; this evolution supports the move towards a Cloud based environment. The focus of this document is primarily on Data Centre environments; however it also applies to the setup of an NFV Point of Presence (POP) in any of the above environments. ETSI ETSI GS NFV-EVE 0
44、07 V3.1.1 (2017-03)9 4.2 Data Centres A Data Centre 1 is defined as follows: “structure, or group of structures, dedicated to the centralized accommodation, interconnection and operation of information technology and network telecommunications equipment providing data storage, processing and transpo
45、rt services together with all the facilities and infrastructures for power distribution and environmental control together with the necessary levels of resilience and security required to provide the desired service availability.“ According to ETSI ES 205 200-2-1 1, a data centre is divided into Ope
46、rator Data Centre (ODC) and Customer Data Centre (CDC). An ODC is a facility embedded within the core network. The facility, therefore, is considered as a service providers asset. A CDC is, on the other hand, a facility that is not directly connected to the core network. The facility is reachable wi
47、th access networks. It is considered as a large branch office, a corporate headquarter, and a data centre operated by an Over-The-Top (OTT) provider. A Data Centre is also considered a place where Network Function Virtualisation Infrastructure (NFVI) nodes would be installed i.1 and i.2. Figure 1 sh

All NFVI equipment within the POP is subject to interfacing within the constraints of the facility infrastructure. Some elements of the facility infrastructure may include cableways, computer room air conditioning units, power plant and power distribution, infrastructure m
