Dark Data Centre - A dark data centre is a facility that is almost exclusively administered remotely through lights-out management (LOM). Tasks that would normally require physical access are automated and are remotely administered.


Data Centre - A data centre is a centralised repository, either physical or virtual, for the storage, management and dissemination of data and information organised around a particular body of knowledge or relating to a particular business.


Data Centre Administrator - A data centre administrator is an employee who is responsible for overseeing data centre operations. They require extensive knowledge about everything that occurs in the data centre.


Data Centre as a Service (DCaaS) - Data centre as a service is the provision of offsite physical data centre facilities and infrastructure to clients. Clients can rent or lease access to the provider’s data centre, using the servers, networking, storage and other computing resources owned by the DCaaS provider.


Data Centre Asset Management (DCAM) – Data centre asset management is the adoption of a BAU task that ensures the assets with a data centre are correctly recorded and maintained. This should include the adoption of specific asset management solutions or processes to help reduce operating costs and maintain a full life cycle for all assets in the data centre.


Data Centre Capacity Planning - Data centre capacity planning is the creation of a strategy that ensures an IT organization's computing resources, power load, footprint and cooling capacity will be able to meet the workload demands of its users and customers.


Data Centre Chiller – A data centre chiller is a cooling system used in a data centre to remove heat from one element and deposit it into another one. Chillers are used to cool the water used in heating, ventilation and HVAC units. Operations of chillers are vital to data centre operation.


Data Centre in a Box - A data centre in a box can also be called a containerised or modular data centre. It is a self-contained computing facility that is manufactured in a factory and shipped to a location. A data centre in a box can give an organisation the ability to buy a ready-made data centre, place it at a location and then link it up to utilities and start using it.


Data Centre Infrastructure Efficiency (DCIE) - DCIE is a metric used to determine the energy efficiency of a data centre.


Data Centre Infrastructure Management (DCIM) - Data centre infrastructure management (DCIM) is the convergence of IT and building facilities functions within an organization. The objective of a DCIM initiative is to provide administrators with a holistic view of a data centre’s performance so that energy, equipment and floor space are used as efficiently as possible.


Data Centre Markup Language (DCML) - DCML is a data centre format model for exchanging information that describes a data centre environment. DCML intends to provide a common description of a data centre.


Data Centre Migration Plan - A data centre migration plan is an organisations strategy for moving a data centre’s devices, applications, systems and cables with minimal disturbance.


Data Centre Outsourcing (DCO) - DCO is the practice of outsourcing the day-to-day provisioning and management of computing and storage resources to a third-party provider. DCO services may include systems management, application performance monitoring, managed hosting, manged storage and database administration.


Data Centre Resiliency - Resiliency is the ability of a data centre to recover quickly and continue operating even when there has been an equipment failure, power outage or other disruption. Data centre resiliency is a planned part of a facilities architecture and is usually associated with other disaster planning.


Desktop Management Interface (DMI) - DMI is an industry framework for managing and keeping track of hardware and software components in a system or personal computers from a central location. DMI was created to automate system management and can be beneficial in a network computing environment where many components are managed.


Device Mounted Device (DMD) - A device mounted device is typically a server blade or network interface card (NIC) that is mounted inside another device, usually a RMD. A server blade for example would usually be mounted inside a large chassis which comprises of various slots in which the blades sit.


Edge Computing - Edge computing is a distributed IT architecture in which client data is processed at the periphery of the network, as close to the originating source as possible.


Electronic Disposal Efficiency (EDE) metric - EDE is the percentage of decommissioned information technology electronics and electrical equipment that is disposed of through known responsible entities. The EDE metric is intended to be used by an organisation to set a benchmark and measure improvement over time.


Enterprise Cloud Storage - Enterprise cloud storage is public storage purchased from a cloud service provider (CSP) for all or most of an organisation. Enterprise cloud storage can be contrasted with consumer cloud storage, which is often free or purchased at a low price for an individual user’s needs. Organisations may turn to an enterprise cloud to solve issues such as high on premise storage costs and the need to upgrade on site infrastructure.


Enterprise Server - An enterprise server is a computer containing programs that collectively serve the needs of an enterprise rather than a single user, department or specialised application.


Enterprise Storage - Enterprise storage is a centralised repository for business information that provides common data management and protection, as well as data sharing functions, through connections to numerous computer systems. An important aspect of an enterprise storage system is unlimited connectivity and support for all the different platforms in operation.


EU Code of Conduct on Data Centres Energy Efficiency - The EU Code of Conduct on Data Centres is a voluntary initiative aimed at reducing the environmental, economic and energy-supply security impact of data centres. The code of conduct has an equipment and system-level scope which focuses on two main areas: the IT load (IT capacity available for the power consumed) and facilities load (equipment and systems that support the IT load, such as cooling systems, PDU’s and UPS).
