Management and operations (M&O) Stamp of Approval - The M&O stamp of approval is a data centre certification that states a data centre meets industry-recognised criteria for uptime. The Uptime Institute award this to help maximise efficiency and uptime in data centres and IT organisations.
Moves, Adds and Changes (MAC) - Moves, adds and changes is a set of tasks that IT teams regularly perform to keep computing equipment up-to-date and aligned with user requirements.
Network Audit - A network audit is the gathering of point to point connections within a network to be able to ascertain whether it is correct in its function or not. The collection of data that a network audit provides allows the business to see whether they are meeting their business objectives and if there are any mistakes on the network that were thought to have not been previously there.
Power Audit - A power audit is a complete inspection of how devices are using the electricity that is being distributed to them and where the power is coming from/going to. This allows a business to know whether there are any single points of failure, if power is being wasted on ghost devices or needs to be re-distributed to lower running costs.
Power Distribution Unit (PDU) - A power distribution unit is a device used for controlling electrical power in a data centre. A basic PDU provides standard electrical outlets for data centre equipment. Floor-mounted and rack-mounted PDUs are more sophisticated and can provide data that can be used for power usage effectiveness PUE calculations.
Raised Floor - A raised floor is a data centre construction model in which a slightly higher floor is constructed above the buildings original concrete slab floor, leaving the open space created between the two for wiring or cooling infrastructure.
Recovery Time Actual (RTA) - RTA is the amount of real-world time it takes for an organisation to recover its systems and business processes following an unplanned disruption. That amount of time can differ significantly from the recovery time objective (RTO), however ideally this should be the same or better.
Reduce, Reuse, Recycle (R3) - Reduce, Reuse and recycle are the three essential components of environmentally responsible consumer behaviour. R3 is sometimes called the waste hierarchy.
Rack Mounted Device (RMD) - A rack mounted device is a piece of equipment, for instance a server or blade chassis, that is housed in a framework comprised of different U-Positions. The frameworks that house the RMD’s are typically called Floor Mounted Devices (FMD’s) or racks. They have numerous bays or u-positions to hold various types of equipment.
Rogue IT – Rogue IT is the use of unsanctioned information technology resources within an organisation.
Single Point of Failure (SPOF) - A single point of failure is a potential risk posed by a flaw in the design, implementation or configuration of a circuit or system in which one fault causes an entire system to stop operating. In a data centre a single fault can compromise the availability of workloads or the entire data centre.
Software Asset Management (SAM) - Software asset management is a business practice that involves the management and optimisation of software applications within an organisation to reduce licence and running costs.
Uninterruptible Power Supply (UPS) - A UPS is a device that allows a computer to keep running for at least a short period when the primary power resource is lost. It also provides protection from power surges.
Zombie Server - A zombie server is a physical server that is running but has no external communications or visibility and contributes no compute resources. It consumes electricity but serves no useful purpose.
