The Big Three

Cooling
If your energy bills have sky rocketed due to conventional data center cooling strategies, try more modern systems designed by CNS and bring it back down to Earth. Designing and engineering modern data center cooling systems, Inrow cooling, free cooling, aisle containment and liquid cooling and following the standards is a big step toward a lower energy bill and ensuring up-time of data centers.
Not Too Hot Or Too Cold, But Just Right
First we make sure you’re not running the data center temperature too low or too high. The Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) has been tracking recommended and allowable temperatures for different types of data centers since mid-2000, in which time the maximum high-end temperature increased from 24 degrees Celsius to 27°C in 2008 and by 2011, ASHRAE defined a range of data center types, wherein maximum allowable temperatures could reach 45°C in high density environments. How does that impact selection of equipment and design?

Right Design
The easiest way to save money is to reduce how many CRAC units are running. A higher- temperature data center matches needs against risk and requires far less cooling; this means fewer CRAC units. In some data centers, half of the CRAC units can be turned off, directly reducing energy and maintenance costs, after number of operational units comes the decision making on cooling options.

Weigh Your Various Data Center Cooling Options
Data centers have options when it comes to a cooling strategy beyond turning the whole room into an artic chill zone. Data center cooling options, from containment to self-cooled cabinets to outside air, come with their own advantages. To determine which data center cooling methods are worth implementing, various choices need consideration. Is cooling ride-through highly important? What about saving energy? Flexibility in design? Using variable-speed CRAC units instead of fixed-speed ones is one option: The CRAC units only run at the speed required to maintain the desired temperature. CRAC units operate most effectively when running at 100%, so some variable-speed systems are not fully optimized when operating at partial load.

Basics
Running standard fixed-rate CRAC units at 100% capacity can build up thermal inertia, another cooling strategy that reduces costs. The data center cools considerably below its target temperature, then the CRAC units are switched off. The data center is then allowed to warm up until it reaches a defined point, and the CRAC units come back on.

Cooling Containment
Cooling containment means separating cool or cold inlet air from hot discharge air. Containment involves erecting barriers — curtains, blanking panels, walls or other designs — to keep the zones separated. The achievable level of cooling containment depends on white space cabinet layout, new facility design and is determined at project planning stages. Containment prevents air flows from mixing, so the air conditioning system doesn’t work as hard to achieve target inlet temperatures. It reduce the number of operating air conditioners. To install containment strict data center layout adds design planning time, fire safety considerations matter, especially if retrofitting an existing space. Cabinets must be arranged front-to-front and back-to-back to alternate rack faces where cool air flows with aisles of exhausts. Close any gaps between cabinets with fillers, and block all unused rack spaces with blanking panels. To prevent air flow over the tops of cabinets and around the ends of rows, fire-rated, anti-static plastic curtains or ceilings are installed above the cabinets. For full containment, solid end panels with doors are erected, as well as either solid barriers between the tops of cabinets and the ceiling, or ceiling panels at cabinet height.

Localized Cooling
Source-of-heat coolers include in-row air conditioners, in-row coolers, above- and below-cabinet coolers, self-cooled cabinets, rear-door coolers, immersion cooling tanks and direct liquid cooling. In-Row Air Conditioners In-row air conditioners are packaged like equipment cabinets to stand within or at the end of rows. Some units discharge air to the cool aisle, while others direct air toward higher-load cabinets. In-row coolers provide chilled water-, condenser water- and refrigerant-based heat transfer, with and without humidity control. Fan speed and cooling capacity are usually controlled via temperature sensors on adjacent cabinets. With enough chilled water reserve and small pumps on an uninterruptible power supply (UPS), they can ride through a power outage. Self-Cooled Cabinets Self-cooled cabinets are the epitome of closed-loop systems. These cabinets recirculate air within their enclosures, cool via water or refrigerant, and work without supplemental cooling in the room.

Rear-Door Coolers
Rear-door coolers are radiators through which chilled water circulates to remove the heat. They replace normal cabinet doors, cooling the hot exhaust air and then discharging it back into the room. When cooling units operate close to computing equipment, it saves the cost of fans pushing cooled air all the way across the room, under the floor or through ductwork. At-the-source cooling also prevents cold air from warming up before it reaches the rack inlet. Since the cooling units are modular, it’s possible to relocate them as compute needs change. Source-of-heat cooling adds flexibility into the data center layout, and prevents redesigns of the building structure or major computer room air conditioner (CRAC) upgrades. Rear-door coolers, for instance, satisfy the total cooling requirement if installed on enough cabinets. In many instances, however, that means every cabinet. Cooling units easily capture hot return air. Systems like in-row coolers work well with containment cooling designs. They use less power than some conventional data center cooling options. They also handle high-power-density cooling, such as 10 or even 25kW cabinets.

Free Air Cooling
Free air cooling is opted if the air outside a data center is regularly below 27 degrees Celsius, free cooling is possible — directly cooling equipment with filtered outside air, or cooling circulating water by outside air, requiring only pumps and no mechanical refrigeration. Kyoto wheels are one example of a free cooling design. Evaporative or adiabatic cooling also uses free air that passes over a moist medium. This technique
absorbs heat through evaporation and works in hotter climates. Free air cooling significantly reduces facility energy use and maintenance tasks. It is often touted as a green or sustainable computing initiative.
Free cooling is an option for a wider mix of data center locations as companies upgrade to higher-operating-temperature servers. Free cooling can also work with mechanical cooling methods.

Data Cabling
In a connected world the importance of data centers is growing, so too does the need for high-quality networks in order for the demands of the digital economy to be met. The modern datacenters relies on quick and efficient exchanges of information, to and from customers and between the active IT components it houses.

The Importance Of Standards
CNS follows the new CENELEC EN 50600 series standards which will impact on data center and buildings that house data centers. The series is separated into practices in terms of building
construction, power distribution, environmental control, telecommunications cabling and security systems, as well as the management and operational systems that oversee all of these. It specifies a classification based around risks including availability, security and energy efficiency. Four Telecommunication Cabling Classes Have Been Developed:
 With no resilience and high risk such as with direct point to point (‘unstructured’) cabling
 With no resilience but fixed cabling systems are deployed
 Concurrently maintainable based on multi-path cabling systems
 Concurrently maintainable based on diverse routed topologies. This is the lowest risk (but highest cost) proposition.

CNS Team Follows Best Practice Program:
Planning
In order to establish the network requirements of the data center in order that the deployment is Consistent with current needs.
Mapping
Ensuring that ‘on-the-ground’ decisions reflect the objectives established through planning, through mapping the requirement onto the actual data center using the most suitable network topology design
Procurement
Making the correct choice of equipment for the network in terms of density, speed, reliability, efficiency, service and support, return on investment etc.

Installation

Since a number of the problems and inefficiencies associated with cabling in the data centers can be traced back to poor installation practices
Management
Since any data center system is only as good as its management and operation, particularly when it needs to bridge a period of significant technological change.
Structured Or Not?
The broad advantages of structured cabling over point to point cabling (such as that used on top of rack configurations in a data center are seen as improved energy efficiency, increased switch port utilization, quicker system adaption, greater scalability, easier network expansion, less maintenance and administration, less expensive switches and overall lower cost of ownership. The structured cabling system can make a network easier to manage, and make it easier also to identify and deal with specific points of failure. It divides up the network into manageable blocks and works on a defined hierarchy of management. The data center is divided into distribution cabling sub-systems – main, intermediate and local. The main distribution cabling sub-system will house the main cross-connects and the core networking equipment. Intermediate sub-systems will house the cross-connect to the equipment areas. Industry consensus suggests structured cabling system makes additions and modifications easier to achieve and allows for flexibility in connections.

Access To Equipment
The connection to the active IT equipment can be made via the top of the rack (ToR), or via the middle of the row (MoR) or via the end of the row (EoR) While there has been some move in recent years towards ToR based on greater convenience of access and improved space utilization, a number of recent studies indicate that energy consumption, flexibility and switch port utilization may be improved through EoR connection based on any Base-T morphology.

There are a number of factors that may influence the design of the network architecture as part of broader cabling planning, including:
Scalability

which additional data can be carried across the network whether on a short-term load-peak basis or as part of a broader data center capacity expansion. As noted previously, networking equipment is so pervasive in data centers that such scalability needs to be easily enabled.
Designing
Designing according to physical constraints of the cabling– link transmission specification, physical flexibility and strength, minimization of interference in order to increase robustness and to prevent any major interruption to transmission.
The Bandwidth And Latency
The bandwidth and latency requirements of the equipment within the data center and the service levels expected of it. Thus, the numbers of servers that are virtualized will increase the complexity of traffic through the data center and in particular this will influence the network topology for switching and routing. The growing emergence of the data center ‘fabric’ which can act as a unified system of connections
between switches and equipment in disparate locations across the data center has acted as one solution to this potential complexity. Yet as with any service that is ‘on demand’ – and this is a key driver for virtual, cloud and software-defined utilities – the network needs to be able to connect at very low latency and without service interruption. Since the processes associated with virtualization usually mean the consolidation of numbers of physical servers into virtual machines then accessed through a smaller numbers of servers, this increases the speed and bandwidth requirements for network connections. Copper, Fiber Or Both? The key cabling profiles of copper and fiber can be deployed to meet the different networking needs of the different spaces in a data center building. The first requirement is to understand the bandwidth requirements of each zone. This will depend upon the density of the servers and the networking equipment within the data center, and in other areas of the building. This will determine the category of copper or fiber cabling required. It indicates also the maximum length of the cable that will transmit at the specified bandwidth.
Testing And Handover?
Testing of each node through authentic Fluke equipment is a critical activity performed by CNS team on each copper and fiber node. After testing a detailed report is prepared and submitted to the facility people for final take over and sign off.
