At first look, the best way knowledge facilities are categorized might not appear particularly necessary. In spite of everything, all knowledge facilities do primarily the identical factor: present house for internet hosting IT tools.
It might not seem to matter a lot which sort of knowledge heart a enterprise chooses. Nevertheless, the assorted knowledge heart classes can play a significant position in figuring out how nicely a knowledge heart suits a given want.
Some kinds of knowledge facilities supply greater levels of availability and uptime than others, as an example. Some supply particular companies, like “white-glove” administration, that aren’t obtainable throughout all classes of knowledge facilities.
Understanding these classification programs is essential for making knowledgeable selections that align with your corporation necessities, efficiency expectations, and funds constraints. Let’s discover the important thing frameworks that outline in the present day’s knowledge heart panorama.
Main Information Heart Classification Strategies
There are a number of approaches to categorizing knowledge facilities. Right here’s a have a look at the commonest sorts.
1. Tiers
Essentially the most well known categorization system for knowledge facilities is the tier system, developed and authorized by the Uptime Institute, which offers steering on growing IT availability and reliability.
The tier system focuses on a knowledge heart’s reliability and uptime ensures. The upper the tier (starting from Tier I to Tier IV), the extra redundant programs are in place, leading to higher resilience in opposition to downtime from energy failures, cooling points, or different infrastructure issues.
Information facilities looking for official tier certification should endure rigorous evaluation and validation by the Uptime Institute, which assesses their design, constructed facility, and operational sustainability earlier than assigning a tier rating. It’s necessary to notice that whereas some knowledge facilities might declare “Tier 5” standing, this isn’t a part of Uptime Institute’s official classification system, which acknowledges solely 4 tiers.
When evaluating services, companies ought to confirm whether or not a knowledge heart has acquired formal Uptime Institute certification or is solely utilizing tier terminology self-referentially. This distinction might considerably influence the precise reliability ensures you obtain.
2. Energy Capability
One other fashionable manner of sorting knowledge facilities relies on how a lot vitality they eat. The determine is often measured in megawatts – therefore why you would possibly see one firm speak about its newest “100 megawatt” knowledge heart undertaking, whereas one other is labeled as a “10 megawatt” facility.
This technique of rating knowledge facilities is sensible within the respect that the extra energy a facility consumes, the bigger it tends to be. Thus, taking note of energy scores might help companies choose knowledge facilities with the suitable scale for dealing with the quantity of IT tools they should deploy.
The draw back of power-based knowledge heart categorization is that complete energy capability has little to do with different necessary elements of knowledge heart operations, like reliability or sustainability.
3. Sustainability Certification
Talking of knowledge heart sustainability, it’s additionally attainable to distinguish between services primarily based on their sustainability standing. Whereas there isn’t a tiering system that assesses various ranges of knowledge heart sustainability, some knowledge facilities maintain certifications associated to sustainability, equivalent to LEED and ISO 50001.
If sustainability is a precedence, selecting a knowledge heart that has attained a particular sustainability commonplace is sensible. Consider, nevertheless, that the general sustainability of a facility doesn’t essentially indicate that particular person racks, servers and workloads are configured in an energy-efficient manner. Nor does it all the time imply that the info heart sources vitality from clear sources. The certifications primarily give attention to vitality effectivity.
4. Information Heart Service Mannequin
Information facilities might be categorized primarily based on the kinds of companies they provide or the shoppers they serve. There are two most important kinds of knowledge facilities on this respect:
-
Non-public knowledge facilities, which serve a particular firm.
Basically, colocation is the best way to go except your corporation’s IT wants are massive sufficient to justify constructing a complete knowledge heart. Colocation additionally affords the advantage of making it straightforward to distribute workloads in varied elements of the world (which may, in flip, enhance latency for customers primarily based in several areas) by buying colocation house in a number of knowledge facilities. And colocation facilities generally supply particular companies, like white-glove monitoring and administration of IT tools, which companies would wish to offer for themselves in a non-public knowledge heart.
5. Measurement
A closing widespread method to evaluating kinds of knowledge facilities is basic descriptions of their general measurement. On this class, the widespread kinds of services embrace:
-
Hyperscale knowledge facilities, a generic time period that refers to very massive services.
-
Conventional knowledge facilities, which means services which are massive however not as big as ‘hyperscale’ places.
-
Modular knowledge facilities, that are sometimes small, though they are often mixed to construct bigger services if desired.
-
Micro knowledge facilities, a fair smaller sort of facility, are sometimes able to supporting only one or two server racks.
All these scores are subjective; there isn’t a formal definition of how massive or small a facility must be to fall into one or the opposite of those classes. Nonetheless, these descriptions might be helpful for organizations looking for a fast evaluation of a knowledge heart’s complete internet hosting capability.
