Data centres seldom meet the operational and capacity requirements of their initial designs. The principal goals in data centre design are flexibility and scalability, which involve site location, building selection, floor layout, electrical system design, mechanical design and modularity. In this article we will take a look at what planning a data centre is all about and offer product solutions from Dell Technologies' Infrastructure Solutions Group (ISG).
A data centre is a physical facility that enterprises use to house their business-critical applications and information. As they evolve from centralised on-premises facilities to edge deployments to public cloud services, it’s important to think long-term about how to maintain their reliability and security.
Data centres are often referred to as a singular thing, but in actuality, they are composed of a number of technical elements. These can be broken down into three categories:
These are the components that IT needs to store and manage the most critical resources that are vital to the continuous operations of an organisation. Because of this, the reliability, efficiency, security, and constant evolution of data centres are typically a top priority. Both software and hardware security measures are a must.
Before you buy the entire Dell solutions catalogue, let's take a look at a quick real-world example and some important questions that need to be answered first.
a financial services firm in Manhattan likely requires continuous operations as any outage could cost millions. The company would likely decide to build two data centres within close proximity, such as New Jersey and Connecticut, that are mirror sites of one another. An entire data centre could then be shut down with no loss of operations because the company could run off just one of them.
On the other hand, small professional-services firms may not need instant access to information and can have a primary data centre in their offices and back the information up to an alternate site across the country on a nightly basis. In the event of an outage, it would start a process to recover the information but would not have the same urgency as a business that relies on real-time data for competitive advantage. It is important to note that when planning a data centre that there is no -one-size-fits-all approach.
To shed some light on your undertaking, here are the key considerations:
Once you've answered all of the questions above you will have a clear foundation on what's needed to plan a data centre. With this out of the way, we need to break down the requirements needed for all of this to work.
The first rule of data centre facilities is to design for flexibility and scalability. Planning ahead should be top of mind at all times.
All data centre designs are judged by their ability to provide continuous operations for the network services they support. Data centre availability is affected by both planned (scheduled maintenance) and unplanned (failures) events. To maximise availability, the impact from each of these must be minimised.
All data centres must be maintained on a regular basis. In most data centre designs, scheduled maintenance is a planned event requiring network downtime. For this reason, general maintenance is often forgone, leaving long-term availability to chance. In robust data centre designs, concurrently maintainable systems are implemented to avoid interruption to normal data centre operations.
To mitigate unplanned outages, both redundancy and fault-tolerance must be incorporated into the data centre design. High availability is accomplished by providing redundancy for all, major and minor, systems, thereby eliminating single points of failure. Additionally, the data centre design must offer predictable uptime by incorporating fault tolerance against hard failures.
Simplicity is most especially for data centres. The major benefits of simplifying within a data centre design are:
Dell Technology offers pre-design and planning services to provide the optimal solutions to meet client needs. This results in an early and accurate alignment between scope, schedule, and budget.
Data centres are limited in terms of footprint, power consumption and cooling capacity. While redundant backup power and fault-tolerant server clusters can potentially increase uptime, they can also reduce the total available power capacity. Planning too much capacity for the given workloads wastes capital expenditures and might draw power to idle, unused servers. Over-provisioning computer room air conditioners also result in below optimal efficiency operation.
IT organizations should start capacity planning with agreed-upon service performance metrics, such as storing data for X amount of days, and running applications with a response time of X. To be effective, the capacity planning process requires sophisticated load calculations both at normal and peak performance times. To determine optimal capacity, IT organizations can benchmark operations with either simulated or real load testing, trend analysis or modelling using tools designed for this purpose.
Capacity planning software tools can help the administrator calculate the resources and power draw that a data centre must support, given current and projected future operations. Such tools range from simple spreadsheets to 3D renderings of the data centre with automated asset discovery and documentation.
