The content presented in the slides is free from any plagiarism and copyright violations and wherever needed appropriate referencing/citations have been provided. In addition to the content in this PowerPoint presentations, I will also be verbally delivering other important content in the class as well as also writing on the board, some information related to the topic being covered wherever necessary. The student is therefore advised to refer to the text books, reference books and any supplementary materials recommended in the Module Information Guide (MIG) or in the PowerPoint presentations for complete understanding of the topic. 2  Unit 1: Fundamentals of Enterprise Data center Design  Plan Data Centre Design Project considerations Project scope Budget Build Budget and Run Budget Criteria Using Rack Location Units System Availability Profiles Insurance and Local Building Codes Determining the Viability of the Project  Overview of Data Centre Elements of Data Center: Power Site raised floor the environmental controls network infrastructure Command Center A data center is a permanent fixture. Hence, servers and storage system components are considered as contents and not part of it  Project Scope Determines the data center design Depends on the company’s requirements and budget Examples: Adding storage devices and servers to Data Centre Separate building construction in new location and adding all necessary utilities project specifications  Budget How much budget is available? Is the budget appropriate for the project scope Is the budget sufficient to satisfy the company’s needs? How much is in general the budget to create the center? How to distribute the funds? Can this distribution be changed? What are the factors included in running costs: maintenance, services, maintenance, … What are the redundancy requirements: services, power, UPS, HVAC. What might be the future changes: power, upgrades, system additions,…  Budget classification Building Budget For building and installing the data centre Running Budget For yearly operating costs repair, maintenance, connectivity, ISP network storage and network equipment, service and support agreements on computers, Electricity cost  Criteria Location (or site) region/building Depends on many factors. practical and affordable Can be near or far to corporate offices Can be on multiple locations Essential criteria Power Physical capacity. Bandwidth Cooling  Criteria Secondary Criteria Plumbing, lighting and other fixtures Doors, windows, walls, loading dock and offices Additional hardware such as card readers , security cameras, door knobs, cabinet equipment, etc. Pallet jacks and other equipment Command Center  Using Rack Location Units (RLUs) Helps to determine the essential criteria: power, cooling, etc RLUs are calculated based on the operating requirements of each rack in the DC In case of varied equipment, varied RLU definitions are required Ex: RLU-A racks for storage racks and RLU-B for server racks (Rack Location Units – Dataspace 2020)  System Availability Profiles Project scope includes the availability requirements of the different data center equipment Determines the mission critical devices (or group of devices) and the less mission critical ones. Availability level is different from one task to another Redundancy requirements: Power redundancies Network redundancies Device redundancies Cooling redundancies Example of Availability Profile (Snevely 2002)  Insurance and Local Building Codes should be considered in all design process aspects All design team and all building contractors are involved. Approval on final plans must be acquired from building authorities and insurers and Aware on the constraints is important Continuous communication with building authorities and insurers can save time  Determining the Viability of the Project Constraints to be considered: Adequateness of the budget Floor adequateness to ceiling height grounding, seismic restraints, cable routing, Are employees qualified? Is the location expensive? Is the region inadequate or too far? Appropriateness of the space Adequateness of the power Cooling capacity Adequateness of ISP services Are fire regulations, Local building codes and insurance too restrictive? Is it exposed to weather or seismic problems? Are fire accidents frequent?  Designing a Data Center Design Process Data Center Support Systems Data Center Structural Layout System Monitoring Physical and Logical Security Remote Systems Management Planning for Possible Expansion  References Snevely, R.
