There are many different types of equipment in a data centre, each with its own dependancies.
Manufacturers of IT equipment issue guidance as to the optimum environmental operating condition for equipment to be kept within in order to maintain warranties. If these are not adhered to warranties inevitably get questioned and in some circumstances they are in danger of being voided.
Spook customers are able to easily stay on top of this and produce evidence based reports at the touch of a button.
DCIM started out as a component of building information modelling (BIM) software, which is used by facilities managers (FM) to create building digital schematic diagrams.
DCIM tools bring the same capabilities to data centres, allowing administrators to collate, store and analyse data related to power and cooling in real time.
The topic of DCIM touches many departments and often spans a data centre's availability and IT reliability requirements. It can identify and eliminate sources of risk to increase availability of critical IT systems (IT) as well as identifying interdependencies between the IT infrastructure teams and the FM department.
As Spook's OmniWatch service has evolved in-line with customer requests, DCIM has organically grown as a natural by-product. OmniWatch presents a joined up, easy to use DCIM solution that is modern and functionally rich.
Ensuring the temperature of IT rooms and IT racks are at a level that will not compromise the efficient running of the equipment contained within is invaluable. Humidity and dew point have important properties too, even air-flow monitoring can be a key indicator that the room is acting unusually.
Monitoring water ingress to detect leaks from air conditioning units and flooding from other areas of the building that may not be IT related such as toilet blocks, water points and pipework and natural floods is vital.
Many potential water ingress points are hidden under raised floors, in false ceiling voids and in adjacent parts of the building, not necessarily directly associated with the data centre.
|Class||Temperature (°C)||Humidity (%)||Max dew point (°C)|
|A1||15 to 30||-12°C DP & 8% RH to 17°C DP and 80% RH||17|
|A2||10 to 35||-12°C DP & 8% RH to 21°C DP and 80% RH||21|
|A3||5 to 40||-12°C DP & 8% RH to 24°C DP and 85% RH||24|
|A4||5 to 45||-12°C DP & 8% RH to 24°C DP and 90% RH||24|
|B||5 to 35||8°C to 28°C DP & 80% RH||28|
|C||5 to 40||-8°C to 28°C DP & 80% RH||28|
ASHRAE issued its first thermal guidelines for data centres in 2004 and recommended temperatures be maintained between 20 and 25°C. They have since stated the ideal range is between 5 to 45°C due to a shift in importance from reliability and uptime to a more energy saving and green approach in equipment.
It is entirely dependent on the rating of equipment as to which of the ASHRE guidelines are adhered. Older and lower rated equipment should always be considered the baseline for any targets as aiming for the higher temperature allowance for new equipment risks damage to the older devices.
Monitoring and measuring power in a data centre has become fundamental. Whether there is a requirement to monitor key power breakers to the data centre via appropriate metering (which provides real-time power load data) or rack level monitoring measuring the power metrics of a power distribution unit (PDU monitoring), each gives valuable power metrics that can be taken into account when installing new equipment or building in appropriate redundancy to the location.
Modern data centres invest in infrastructure to ensure seamless power provision to equipment should the power utility service providers cease to successfully deliver mains power. This is known a ‘power redundancy'.
By measuring key power metrics and monitoring equipment status levels means early warnings to power related issues can be managed efficiently.
|PUE||DCiE||Level of efficiency|
By monitoring PUE and DCiE in real-time ensures a business can measure and create a clear audit as efficiencies are gained. Spook's free PUE/DCiE calculator will give you an insight into how efficient your power efficiency is.
The objective is to ensure that the maximum possible percentage of power utilised in a data centre is actually used by IT equipment and the minimum by supporting equipment such as AC units.
Clearly things such as antiquated and/or unreliable AC units will have an adverse effect on the power efficiencies.
However knowing what the power efficiency figures in real time and being able to review these over time allows customers to highlight areas for improvement for a better overall power efficiency rating.
The Data Centres Energy Efficiency CoC has been established in response to increasing energy consumption in data centres and the need to reduce the related environmental, economic and energy supply security impacts.
The aim is to inform and stimulate data centre operators and owners to reduce energy consumption in a cost-effective manner without hampering the mission critical function of data centres.
The Code of Conduct aims to achieve this by improving understanding of energy demand within the data centre, raising awareness, and recommending energy efficient best practice and targets.Read more 2019 best practice guidlines
