PTSdcs. com Data Center Function The functional requirements of any data center space are fourfold: 1. To provide a safe and secure place to locate mission critical equipment 2. To provide sufficient power protection to maintain the critical load 3. To provide adequate environmental controls, including cooling and fire safety, to operate the space within the critical loads operating parameters 4.
To provide communications connectivity both inside and outside the space Data Center Philosophy The goal of any data center is to provide continuous availability of all network services. Therefore, whether discussing the network design strategy or the facility design strategy the overall philosophy remains the same: Keep it as simple as possible Design for scalability Utilize modularity wherever possible Be flexible and adaptable to change Data Center Description The term ‘data center’ is used ubiquitously to describe the space(s) serving as the operating theatre for the enterprise’s network service delivery.
It has also been described by many other names including computer room, datacenter (spelled incorrectly), data centre (European), server room, network room, network closet, telecommunications room and so on. The most common differentiator between describing your space as a data center and calling it a computer room tends to be scale. However, the official delineator is how the space’s functional pieces are put together. The term ‘data center’ is the description given when the entire site and building shell are utilized exclusively as a data center site.
The Homework on Mis650. Data Centers
1. PUE (Power usage effectiveness), the ratio of total facility energy to IT equipment energy within a data computer, which measures how much of the power is actually used by the computing equipment. It is an important place to start when considering how to reduce data center power consumption because it is one of the most effective metrics for measuring data center energy efficiency. PUE is ...
Therefore, a data center can be described as a larger space composed of smaller spaces including: Computer Room(s) Telecommunications Room(s) Entrance Room(s) Network Operations Center Electrical Room(s) Figure 1: Relationship of spaces in a data center. TIA-942, April 2004 Mechanical Room(s) War Room / Conference Room(s) Staging Area, Storage, and Loading Dock People Spaces – Common Areas & General Office Spaces Typically, the ratio of IT space to support space has declined to about 1:1 as compaction has emerged and developed as a trend in the industry.
From this description it is obvious that a ‘computer room’ is a functional space within a ‘data center’. Interestingly enough, both spaces are described as places to secure information systems, technology data, and infrastructure. 3 ©2006 PTS Data Center Solutions. All rights reserved.

The typical data center includes a single entrance room, one or more telecommunications rooms, one main distribution area, and several horizontal distribution areas. Figure 2: Example of a basic data center topology TIA-942, April 2004 Data Center Systems and Sub-Systems The following are just some of the major systems and sub-systems that make up any data center location: Information Technology (IT) Infrastructure Network & Network Security Equipment Voice & Data Communications Equipment Server & Data Storage Equipment Structured Cabling

The Essay on National Climatic Data Center
The following CVR records indicated that the captain was trying his level best to regain control the flight. The FDR and the CVR stopped recording at 0150:36. 64 EST and 0150:38. 47 EST with its last indication that the elevators remained in a split condition. The rest of the flight information was gathered from the two debris fields recorded radar data. Primary radar data demonstrate that the ...

PTSdcs. com Computer Room Description The best description for a Computer Room however is a Collapsed Data Center where the entrance room is contained within the computer room space. The computer room is the space that serves the purpose of providing a secure environment for the equipment and cabling directly related to the critical load.
Since this is the principle location for network and server infrastructure special considerations must be given to: Power protection Power distribution Cooling Humidity control Air distribution Fire Safety Floor layout Floor loading Service clearances Cable pathway Physical security Signage Figure 3: Example of a collapsed data center topology TIA-942, April 2004 Data center design Criteria Rob Sneevely, in his book, Enterprise Data Center Design and Methodology, correctly defines the criterion for a data center design as, “…the requirement that must be met to provide the system capacities and availability necessary to run the business. However, the design criterion for a data center project differs slightly from that of a computer room project. In either case, data center design and/or computer room design are accomplished by identifying the key design criteria for the two (2) main areas of the project focus, the Technology Infrastructure & Services (IT) and the Support Infrastructure & Services (the Facility).
The key design criteria are: Business Objectives (Scope) Availability Requirement Power & Cooling Density Since a data center project typically involves base-building design, Site Selection, must also be included as a criterion placed on the overall design. ©2006 PTS Data Center Solutions.

The Review on An Archery Test Rig Made Using Computer Aided Design
To achieve the project objective, the test rig structure must be design and suitable for place the archery testing apparatus. We need to develop tools that can test the efficiency in archery equipment. The arrows were made of pine and consisted of a main shaft and about 15–20 centimeter (6–8 inches) long fore shaft with a flint point. This led the commercial development of new forms of bow ...
Additionally, the space requirements for a computer room project are, unfortunately, often previously dictated by Management and/or the project architect. This complicates the design by restricting the power & cooling density strategy utilized as a criterion. Inevitably, this also increases the overall cost of the project. Establishing the design criteria to be utilized within the project will lead to the determination of: Space requirements Budget requirement Time requirements Conclusion
Understanding the proper nomenclature is only one small step in the road to delivering a successful data center and/or computer room project. A computer room is just one of the components that make up a data center environment whose goal is to provide continuous availability of network services. Ultimately, both spaces rely on the integration of the IT and facility infrastructure necessary to deliver a space that meets the company’s business objectives. 6 ©2006 PTS Data Center Solutions.
