cooling

As high-density IT equipment becomes the new normal, the amount of heat generated continues to grow substantially – as does the challenge of efficiently cooling data centers. Traditional perimeter and/or raised floor computer room air conditioning systems increasingly struggle to remove concentrated heat loads. In many small to mid-size data centers, implementing close-coupled cooling solutions can be a highly effective and efficient strategy for supplementing cooling capacity. Located in or near server racks, close-coupled air conditioning units focus cooling where it is needed most without lowering the temperature of the entire data center. In addition, these modular solutions make it easy to reconfigure cooling to handle new equipment or eliminate hot spots. As a result, using close-coupled portable, rack-mounted or row-based air conditioning units tailored to your specific data center needs can boost cooling efficiency and add valuable flexibility.

Cooling tends to take a back seat to other concerns when server rooms and small to mid-size data centers are first built. As computing needs grow, increased heat production can compromise equipment performance and cause shutdowns. Haphazard data center expansion creates cooling inefficiencies that magnify these heat-related problems. End users may assume they need to increase cooling capacity, but this is often unnecessary. In most cases, low-cost rack cooling best practices will solve heat-related problems. Best practices optimize airflow, increase efficiency, prevent downtime and reduce costs.

When you’re designing a data center, server room or network closet, deciding which racks to deploy and how to configure them should be at the top of your list. Just like building a house, the surface details may steal the spotlight, but it’s the quality of the underlying foundation that makes the difference between success and frustration. Racks organize IT equipment, such as servers and network switches, into standardized assemblies that make efficient use of space and other resources. Depending on the options you choose, they can also improve power protection, cooling, cable management, device management, physical security, mobility, ease of installation and protection from harsh environmental conditions. Choosing the right racks and configuring them to match your needs will ensure that your IT equipment operates reliably and efficiently, saving your organization from costly downtime and other needless expenses.

The average computer room today has cooling capacity that is nearly four times the IT heat load. Using data from 45 sites reviewed by Upsite Technologies, this white paper will show how you can calculate, benchmark, interpret, and benefit from a simple and practical metric called the Cooling Capacity Factor (CCF). Calculating the CCF is the quickest and easiest way to determine cooling infrastructure utilization and potential gains to be realized by AFM improvements.

Faster, more powerful and dense computing hardware generates significant heat and imposes considerable data center cooling requirements.

Ensuring the reliability and efficiency of your data center operations requires a strategic partner that is qualified to minimize energy usage, reduce costs, and optimize space utilization, helping you meet critical business initiatives.

This paper discusses making realistic improvements to power, cooling, racks, physical security, monitoring, and lighting. The focus of this paper is on small server rooms and branch offices with up to 10kW of IT load.

This white paper compares the cost of both scenarios, presents the advantages and disadvantages of each, and identifies which environments can best leverage the facility module approach.

A 10-year total cost of ownership (TCO) analysis is provided showing li-ion is 39% less than VRLA despite their capital cost premium. A sensitivity analysis reveals the TCO drivers. Finally we discuss li-ion batteries for retrofit and new UPS applications and the effect of temperature on battery life, runtime, and cooling.

This paper explains some of the causes of stranded power, cooling, and space capacity in colocation data centers and explains how high-density rack power distribution, air containment, and other practices improve availability and efficiency. Examples of acceptable use policies that address these issues are provided.

In some cases, adopting cloud IoT platform may make more sense where required processes, communication costs and cloud costs meet sufficient total cost of ownership against deploying MDC. Additionally, in situations that an end-user organization already has a secure room or a modular data center solution where infrastructure can be housed and/or the amount of infrastructure involved may be too small to benefit from power/cooling advantages of being housed in an MDC, the organization may not see a need for an MDC. An MDC is nothing more than a smaller form of a modular data center, and a number of providers have entered the modular data center solutions space in the past. These modular data center solution providers came into the market with high expectations for growth and ROI only to find that high sales were not forthcoming due to limited use cases, so many exited the space.

An uncertain business world still calls for reductions in total cost of ownership. Yet, today's IT manager must also focus on expanding efficiencies and enhancing optimization. Fortunately, server virtualization can assist in each of these areas.

Server virtualization is no longer a luxury but an essential part of the modern data center. By combining the workloads of several underused servers, you can get more out of your hardware when IT budgets stay flat, even as demand goes up.

The time is right for your organization to benefit from the greater hardware utilization, decreased capital expenditures, reduced power and cooling costs, accelerated productivity and enhanced disaster recovery delivered by server virtualization.

Although the cost of flash storage solutions continues to fall, on a per-gigabyte capacity basis, it is still significantly more expensive to acquire than traditional hard drives. However, when the cost per gigabyte is examined in terms of TCO, and the customer looks past the pure acquisition cost and accounts for “soft factors” such as prolonging the life of a data center, lower operating costs (for example, power and cooling), increased flexibility and scalability, or the service levels that a flash solution enables, flash solution costs become increasingly competitive with spinning media.
