Modern-day Data Centers provide massive computational capabilities while having a smaller footprint. This poses a significant challenge for keeping the Data Center cool, since more transistors in computer chips, means more heat dissipation, which requires greater cooling. Thereby, it has come to a point where traditional cooling systems are no longer adequate for modern Data Center cooling.

Legacy Cooling: Most Data Centers still use legacy cooling systems. They use raised floors to deliver cold air to Data Center servers, and this comes from Computer Room Air Conditioner (CRAC) units. These Data Centers use perforated tiles to allow cold air to leave from the plenum to enter the main area near the servers. Once this air passes through the server units, heated air is then returned to the CRAC unit for cooling. CRAC units have humidifiers to produce steam for running fans for cooling. Hence, they also ensure the required humidity conditions.

However, as room dimensions increased in modern Data Centers, legacy cooling systems become inadequate. These Data Centers need additional cooling systems besides the CRAC unit. Here is a list of techniques and methods used for modern Data Center cooling.

Server Cooling: Heat generated by the servers are absorbed and drawn away using a combination of fans, heat sinks, pipes within ITE (Information Technology Equipment) units.1 Sometimes, a server immersion cooling system may also be used for enhanced heat transfer.

Space Cooling: The overall heat generated within a Data Center is also transferred to air and then into a liquid form using the CRAC unit.

Heat Rejection: Heat rejection is an integral part of the overall cooling process. The heat taken from the server is displaced using CRAC units, CRAH (Computer Room Air Handler) units, split systems, airside economization, direct evaporative cooling and indirect evaporative cooling systems. An economizing cooling system turns off the refrigerant cycle drawing air from outside into the Data Center so that the inside air can get mixed with the outside air to create a balance. Evaporated water is used by these systems to supplement this process by absorbing energy into chilled water and then lowering the bulb temperature to match the temperature of the air.

Containments: Hot and cold aisle containment use air handlers to contain cool or hot air and let the remaining air out. A hot containment would contain hot exhaust air and let cooler air out while cold containment would do vice versa.3 Many new Data Centers use hot aisle containment which is considered as a more flexible cooling solution as it can meet the demands of increased density of systems.

Closed-Couple cooling: Closed-Couple Cooling or CCC includes above-rack, in-rack or rear-door heat exchanger systems. It involves bringing the cooling system closer to the server racks itself for enhanced heat-exchange.2 This technology is very effective as well as flexible with long-term provisions but requires significant investments.

Conclusion

Companies can choose a cooling system based on the cooling needs, infrastructure density, uptime needs, space factors, and cost factors. The choice of the right cooling system becomes critical when the Data Center needs to have high uptime and avoid any downtime due to energy issues.

Data Center migration is essential for companies looking to meet the growing demands of the IT/data services. However essential, this process comes with its own set of challenges. Thus, it would be wise to tread carefully and assess both the core necessities and challenges that usually accompany Data Center migration.

Data Center migration involves moving a part or the entire IT operation of a company from the existing Data Center to another, either physically or virtually (shared Data Centers via the cloud). Here are the five basic challenges, or rather considerations to make for a successful Data Center migration:

1. Service Provider Credentials

Before rushing into a collaboration with a Data Center migration provider, it is important to assess the service providers business; what is their track record of providing Data Center services as well as maintaining colocation Data Centers; do they operate by purchasing the Data Center services from multiple providers; what are the terms and conditions. Usually, if a provider leases services instead of having their own facilities, it can be safely said that it will not offer stability or efficiency in delivering the pivotal IT needs for a digital enterprise.

Hence, doing a little research ahead of the Data Center migration about the provider helps assess the quality of services of the provider.

2. Customer Service

An excellent customer service is demanded of any service, and Data Center migration is no exception. Providers that have created a good track record of their services in the market have done so by not only delivering seamless and actionable IT/data solutions but also by catering to the minor troubles and issues faced by their customers. The services of good providers are accompanied by on-demand expert assistance with less wait time. Also, one has to consider whether or not a prospective provider can meet all the expectations and business demands as and when necessary. Thus, companies should always try to dig a little deeper to gain knowledge about the customer service of a provider before choosing one for Data Center migration.

3. Data Center Location

The location of a service provider’s Data Center is a major factor for the future operations of a company. It may be so that a provider promises to deliver all the core needs of a company today, but in the future, they may falter from that promise. For instance, if a provider takes over another Data Center provider’s location, there are chances that the Data Center facilities may fall within close proximity of each other. As a result, the service provider may feel it’s unnecessary to have multiple Data Centers situated closely and may shut down some chosen locations. This can become a huge inconvenience if a company’s location is in the phase out location. Thus, to avoid such unsavory situations, it’s best to choose a provider with their own facilities located strategically.

4. Service Bundling

Customers can hugely benefit from Data Center providers that provide access to facility resources and network connectivity to the users. However, not all providers are able to deliver this. Providers that do not own their own facilities, locations, and operations, often collaborate with third-party providers or platforms, which may cease to exist in the future. And when that happens, it is sure to affect a company’s operations. And it might end up in a situation where the customers will have to make adjustments with two separate providers that may no longer be able to offer seamless and efficient services.

5. Reliability

Finally, one of the most important factors to consider for Data Center migration is the reliability of the service provider. To determine this, one has to analyze the security systems, HVAC features, OPEX, availability and uptime, and other such measures. It would be wise to choose a provider with a history of minimal number of service outages, since a service outage can cost you dearly. Also, while choosing a provider, one should check if it is a certified Data Center that offers stable, cost-efficient, and state-of-the-art services.

These are the five core areas where companies can face numerous challenges while opting for a Data Center migration. However, they can be easily overcome if addressed with a little caution and risk-assessment approach.

For one reason or another, every business requires a Data Center at some point. There is an ever-increasing demand for data everywhere, and as a result of this, companies require more and more processing power and storage space.

There isn’t a specific kind of company that will require a Data Center, but some are more likely to require it than others. For instance, any kind of business which uses, processes, or stores a lot of data will definitely require a Data Center. These businesses can be educational institutions – like schools or colleges, telecom companies, or even social networking services. Without constant access to data, these companies can fall short on providing essential services. This can lead to loss of customer satisfaction as well as revenue.

Earlier, businesses only had the option of going for a physical Data Center, where data would be stored across several devices in a single facility. At such a time, to ensure smooth operations of the Data Center, it was enough simply to have an efficient cooling strategy in which power was judiciously used.

With the rise in technology, however, cloud servers are now available on which data can be stored remotely. As a result of this, the future of Data Centers is one in which all devices are connected across several different networks. This requires more Data Center elements than existed previously. Moreover, the metrics on which the efficiency of a Data Center is judged have also evolved.

There are now 4 factors according to which the success of a Data Center can be determined. They are:

• Infrastructure
• Optimization
• Sizing
• Sustainability

Infrastructure

A lot of businesses forget the fact that infrastructure can directly impact the performance of a network. Maximizing network performance can be achieved by paying attention to three parts of the complete infrastructure – the first being structured cabling, the second being racks and cabinets, and the third being cable management.

To take just one example, scalable as well as feasible rack and cabinet solutions are an effective way of realizing this. Not only can they accommodate greater weight thresholds, but they also have movable rails and broader vertical managers. This provides options for increased cable support, airflow, and protection.

Optimization

The faster a Data Centers expands, the quicker it grows in terms of size and complexity. This requires significantly quick deployment time. A Data Center needs to be updated regularly to support the growing needs of a business. Purchasing infrastructure solutions which can optimize time will be a wise decision in this regard – it will help in manifold ways by making it easier to move infrastructure, or to make additions or subtractions to an already existing setup.

A modular solution can become the foundation for scalable building infrastructure and save time as well! Modular racks and cabinets can be put together quickly, and also have adjustable rails and greater weight thresholds. Thus, they can accommodate new equipment very easily. Such a modular solution can support future changes in the network as well, without increasing the scope of disruption.

Sizing

Earlier, the one key factor in assessing the efficiency of a Data Center in terms of size was to see how fast it would grow. Accordingly, the infrastructure supporting it would also grow. While sounding simple in theory, such a principled decision – that expansion will happen without any forethought – is detrimental both in terms of capital as well as energy.

The truth is that space is a premium everywhere – so why shouldn’t this be the case while considering a Data Center? An infrastructure system should always be built for optimization, so that the process of scaling is straightforward and not beset by liabilities of any kind. One simple way to achieve this is to adopt the rack as the basic building block for a Data Center.

Sustainability

Sustainability is not a singular concept. While it is often associated with not destroying natural resources, it can also be tailored to achieve the opposite effect – to conserve them. A myth is often propagated regarding natural resources – that it is more expensive to streamline processes to be sustainable. The truth is that it costs the same and, moreover, it has a lot of benefits as well.

When sustainable manufacturers design solutions which lower the overall impact your Data Center will have on the environment, it translates into more flexibility in terms of design, shorter installation times, as well as reduction in material waste on site – and much, much more. The key factor is energy efficiency, and therefore all other processes are streamlined to fit this metric.

It is no longer enough simply to consider effective cooling and energy solutions as the be-all and end-all of Data Center operations. Data Centers play a crucial role in terms of a business’ overall success, and trying simply to maximize efficiency within a Data Center is a short-sighted target. Other forms of efficiency can equip the Data Center to be changed later at reduced costs, thus making it more capital-effective.

Ultimately, the goal should be to make the Data Center have efficient infrastructure and optimized modular solutions. In addition, it should be scalable in terms of size, without incurring liabilities, and should also be sustainable, as it will help with all of the above.

A Data Center is usually a physical location in which enterprises store their data as well as other applications crucial to the functioning of their organization. Most often these Data Centers store a majority of the IT equipment – this includes routers, servers, networking switches, storage subsystems, firewalls, and any extraneous equipment which is employed. A Data Center typically also includes appropriate infrastructure which facilitates storage of this order; this often includes electrical switching, backup generators, ventilation and other cooling systems, uninterruptible power supplies, and more. This obviously translates into a physical space in which these provisions can be stored and which is also sufficiently secure.

But while Data Centers are often thought of as occupying only one physical location, in reality they can also be dispersed over several physical locations or be based on a cloud hosting service, in which case their physical location becomes all but negligible. Data Centers too, much like any technology, are going through constant innovation and development. As a result of this, there is no one rigid definition of what a Data Center is, no all-encompassing way to imagine what they are in theory and what they should look like on the ground.

A lot of businesses these days operate from multiple locations at the same time or have remote operations set up. To meet the needs of these businesses, their Data Centers will have to grow and learn with them – the reliance is not so much on physical locations anymore as it is on remotely accessible servers and cloud-based networks. Because the businesses themselves are distributed and ever-changing, the need of the hour is for Data Centers to be the same: scalable as well as open to movement.

And so, new key technologies are being developed to make sure that Data Centers can cater to the requirements of a digital enterprise. These technologies include –

• Public Clouds
• Hyper converged infrastructure
• GPU Computing
• Micro segmentation
• Non-volatile memory express

Public Clouds

Businesses have always had the option of building a Data Center of their own, to do which they could either use a managed service partner or a hosting vendor. While this shifted the ownership as well as the economic burden of running a Data Center entirely, it couldn’t have as much of a drastic effect to due to the time it took to manage these processes. With the rise of cloud-based Data Centers, businesses now have the option of having a virtual Data Center in the cloud without the waiting time or the inconvenience of having to physically reach a location.

Hyper converged infrastructure

What hyper converged infrastructure (HCI) does is simple: it takes out the effort involved in deploying appliances. Impressively, it does so without disrupting the already ongoing processes, beginning from the level of the servers, all the way to IT operations. This appliance provided by HCI is easy to deploy and is based on commodity hardware which can scale simply by adding more nodes. While early uses that HCI found revolved around desktop virtualization, recently it has grown to being helpful in other business applications involving databases as well as unified communications.

GPU Computing

While most computing has so far been done using Central Processing Units (CPUs), the expansive fields of machine learning and IoT have placed a new responsibility on Graphics Processing Units (GPUs). GPUs were originally used only to play graphics-intensive games, but are now being used for other purposes as well. They operate fundamentally differently from CPUs as they can process several different threads in tandem, and this makes them ideal for a new generation of Data Centers.

Micro segmentation

Micro segmentation is a method through which secure zones are created in a Data Center, curtailing any problems which may arise through any intrusive traffic which bypasses firewalls or. It is done primarily through and in software, so it doesn’t take long to implement. This happens because all the resources in one place can be isolated from each other in such a way that if a breach does happen, the damage is immediately mitigated. Micro segmentation is typically done in software, making it very agile.

Non-volatile memory express

The breakneck speed at which everything is getting digitized these days is a definitive indication that data needs to move faster as well! While older storage protocols like Advanced Technology Attachment (ATA) and the small computer system interface (SCSI) have been been impacting technology since time immemorial, a new technology called Non-volatile memory express (NVMe) is threatening their presence. As a storage protocol, NVMe can accelerate the rate at which information is transferred between solid state drives and any corresponding systems. In doing so, they greatly improve data transfer rates.

The future is here!

It is no secret that Data Centers are an essential part of the success of all businesses, regardless of their size or their industry. And this is only going to play a more and more important factor as time progresses. A radical technological shift is currently underway: it is bound to change the way a Data Center is conceptualized as well as actualized. What remains to be seen is which of these technologies will take center stage in the years to come.
