Datacentre Planning

Planning is the most critical element of any Data Centre or server room project and often involves the integration of many people including consultants, architects, engineers, health & safety, quantity surveyors and the client’s team.

In addition, the complexity of the new components, the existing infrastructure of any Data Centre or server room plus building and utility services must also be considered along with the demands of CDM regulations, local authorities, planning issues, waste management and building standards.

Planning mistakes can magnify and propagate through later deployment phases, resulting in delays, cost overruns, wasted time, and ultimately a compromised system.

on365’s proven approach to the design, planning and build of energy efficient Data Centres and server rooms delivers fully operational facilities ready for your critical IT servers and network with high levels of efficiency, resilience and performance ensuring business continuity and maximised uptime. We provide comprehensive space, layout, capacity and implementation planning and we ensure that fundamental physical build and location criteria are addressed as well as compliance with appropriate Building Regulations and Planning Approvals.

on365 remove much of the complexity from IT planning by adopting a “dataflow” philosophy. This incorporates dependencies and design strategy with an orderly sequence of tasks that progressively transform and refine information from initial concept to final design. Not only that but we ensure that system plans are communicated among the various business stakeholders within the organisation and that all those involved have the necessary information in order to make decisions.

on365 adopt this method at every stage of the planning phase and by implementing this philosophy on365 ensure workload is reduced, unnecessary expense is minimised, project schedules are accelerated and decision making simplified for all of our clients.

on365 provide comprehensive and detailed planning using MS Project Planner for the following key aspects of any Data Centre or server room build;

  • Space     
  • Layout
  • Capacity     
  • Implementation
  • Physical build    
  • Location


This is all delivered ensuring full compliance with appropriate regulations;

  • CDM Regulations
  • Building Regulations & Standards
  • Planning Approvals
  • Waste Management
  • Health & Safety     

Datacentre Planning Sequence

Initial steps include assigning of responsibilities, project management appointment, agreeing and creating outsourcing relationships,
budgeting, and scheduling.

System planning
A clearly structured plan of data flow, business dependencies, and design strategy provides essential guidance. This “system planning
sequence” is the pre-determined flow of ideas, historic activity, and data that transforms the initial project idea into a detailed installation
plan. This part of the implementation plan has five clear sections that make it much easier to visualise and comprehend the flow of detailed
activity that brings the plan to life.

1. Determine IT Requirements
Through better understanding of an organisation’s current and future IT needs, on365 can advise the necessary changes and improvements to IT capability. From this point we can easily determine three important factors that will help shape the IT plan - criticality, capacity and expected growth - once established these three parameters help to begin developing the physical device requirement.

2. Develop System Concept

This stage of the on365 process takes the foundation parameters – criticality, capacity, and growth plan – and uses them to formulate a general concept of the physical infrastructure. The cornerstone of this is the selection of a reference design, which embodies the desired criticality and capacity, and has a scalability that will support the growth plan.

Things that the user or client would like, but are subject to change or adjustment after consideration (or reconsideration) of cost and consequences.

Things that either cannot be changed, or can only be changed at great expense or with unacceptable consequences. Constraints are pre-existing conditions that are difficult or impossible to change.

4. Generate Specification

The on365 process of translating the user requirements (from the previous task) into a detailed kit-list. This particular sequence uses the intermediate step of creating a system specification. The specification consists of the following elements:

on365 specifications that do not vary from project to project. Examples of standard specifications are regulatory compliance, compatibility of subsystems, workmanship, safety, and best practices.

Client specifications that define the client-specific details of this project

5. Generate Detailed Design

The last task in the planning sequence is the creation of a detailed final design for the installed system, this would typically include:

  • Detailed kit-list
  • Exact floor plan of racks, to include power and cooling considerations
  • Detailed installation plans and instructions
  • Detailed project schedule
  • Description of characteristics of the completed design, including efficiency, density, and expandability.
