Steve Hassell President, Data Center Solutions, Emerson Network Power P.S. Please join us in celebrating Emerson s 125 year anniversary. We look forward to continuing to show our customers that by partnering with us they can Consider It Solved, and we look forward to tackling future challenges together! Six Data Center Trends to Watch in 2015 Every New Year is the time for predictions and resolutions. While the accuracy rate of predictions in the technology space are usually only slightly north of the success rate of a New Year s resolution, the thought processes involved with creating (not to mention debating/ defending) the list can be very useful. So we decided to give it a try. At Emerson Network Power, we re blessed with a large (and lively) group of passionate data center customers and internal experts from around the world. We asked these folks to reflect on their experiences and give us some predictions/trends for the coming year. We collated the responses, destroyed the names to protect the guilty, and looked for common themes. In the end, six strong themes emerged for 2015: 1. Cloud comes of age Certainly the term cloud is nothing new: Most organizations already use some form of software-as-a-service (SaaS), and many have adopted cloud (or at least cloud-like ) infrastructure components in their environments. Now cloud is poised to expand from that foothold and become an engine of innovation, with cloud providers driving that innovation as they adopt technologies, business models and practices that achieve high reliability and application mobility at the lowest possible cost. 2. Integration extends its reach With rapid changes in many markets being driven by innovation, digitization and mobility, the need for speed that integration and convergence delivers is greater than ever. As a result, integration and convergence have expanded beyond the IT stack to the systems that support that stack. In this new environment, any space becomes a self-maintaining computing space, and entire data center facilities are now being designed and constructed from integrated, prefabricated modules.

3 3. Convergence goes macro Technology systems aren t the only things experiencing a convergence. The telecommunications and IT industries are moving closer together as voice and data services are now routinely consumed on the same device. This convergence will drive more standardization in the technologies used to support voice and data services and break down the silos that have traditionally existed between these two critical functions. 4. Software paves the way for more software Virtualization marked one of the most significant trends in the data center industry in the last twenty years. The impact of this development will continue to drive change for the foreseeable future as virtualization extends beyond computing to networking and storage. An interesting paradox begins to develop where application development and deployment gets much easier and faster, while understanding the underlying physical environment and dependencies becomes harder. One of the key challenges in this virtual revolution is going to be hardware management. 5. The edge gets stronger After years of consolidation and centralization, IT organizations are turning their attention to the edge of the network to improve interactions with customers and applications. As organizations grow their use of analytics, location-based services, and personalized content, edge of network facilities will become critical in achieving competitive advantage. 6. Security becomes the new availability While downtime is still a risk for data center managers, a new threat has emerged in the form of cyber security. Increasingly, data center and facility managers will have to work with their IT security teams to audit the technology and software of infrastructure equipment to ensure security and evaluate the security practices of the contractors and service providers that have access to that equipment. So what does all of this mean? In the past we ve all experienced technology changes within the data center, but now the very concept of what is a data center is changing as well. Virtualization and edge computing are erasing walls, hybrid clouds and telecom/it convergence are challenging models, and more complex infrastructure management and security challenges are causing nightmares. We re probably due for a more holistic, intelligent and integrated approach to data center design and operation, which results in a new generation of facilities that make more effective use of capital, can respond faster to changing requirements, and that enable simpler management and more accurate forecasting.

10 5 Top Considerations For Selecting A UPS New technologies and increasing demands are causing data center managers to look to UPS solutions for efficiency and scalability in addition to availability. The considerations below will help you select the right UPS solution for both current and future needs and help optimize the performance of your data center. 1: UPS Topology UPS internal topology (configuration) determines the relationship between the UPS output power quality and incoming utility power and, ultimately, the effectiveness of the UPS at protecting against certain types of power disturbances. Topology is a primary determinant of system reliability and functionality, two key elements of availability. Historically, there have been three basic types of UPS topology: Passive Standby: While this topology gets high marks for simplicity, the limitations of the design such as the lack of power conditioning, brief power interruption during transfers, or generator compatibility make it unsuitable for three-phase applications. Line-interactive: This topology resembles passive standby, but inserts a transformer or inductor in series between the utility power source and the load. Like the passive standby topology, line-interactive can be lower cost but effective, because it supports the entire critical load during power disturbances for the duration of the battery. Power Problems Line Noise Frequency Variation Switching Transients Harmonic Distortion Under Voltage Over Voltage Power Sag Power Surge Power Outage Passive Standby Liebert NXL UPS On-line Double-Conversion: Online double-conversion topologies have emerged as the preferred topology for the data center, displacing standby and line-interactive UPS systems in network access rooms as availability requirements rise. Properly configured, it is the only topology that protects against the full range of power disturbances experienced by data center power systems. Line-Interactive 2: Availability On-line Double- Conversion To ensure your data center UPS solution can protect uptime even during multiple, simultaneous power and environmental events without forcing a switch to bypass, look for: Continuous-duty static switch: Ensures maximum fault clearing capability in case of extreme overload or downstream faults No contactors in the bypass path: Contactors are not designed for high withstand requirements Redundant fans: Provides the ability to tolerate more than a single fan failure before going to bypass High withstand rating (100kA or higher): Allows the equipment to stay online during more severe short circuit or circuit overload conditions 10 Spring 2015 EmersonNetworkPower.com

11 Ability to start a like-sized Power Distribution Unit (PDU) without transfer to bypass: Keeps the system on protected power when additional distribution is added 3: Efficiency While UPS power consumption has improved significantly since the days of 79 percent efficiencies, some continue to consume more energy than is necessary. Most estimates put the average efficiency at 86.6 percent- -well below the 93 percent that is achievable in newer technologies. 4: Scalability and Flexibility Power system flexibility can be provided by a new generation of power systems that are designed for simplified configuration changes and greater scalability, enabling systems to be right-sized during the design phase. Virtually every component of the data center physical infrastructure is now available in a modular design, including power systems. These modular systems are typically integrated packages of equipment and controls that are built and pre-tested in a factory environment. The shorter deployment time, combined with the capacity-ondemand approach offered by modularity, allows organizations to quickly meet fluctuating demands while managing capital expenditure costs and maintaining higher operating efficiencies. 5: Design There are a number of new technologies that expand upon the on-line double-conversion topology to lower CapEx and OpEx costs, while providing greater scalability and minimizing availability compromises, such as: Transformer-Free UPS: Offers high efficiency, smaller footprint and improved flexibility while providing high levels of availability. Capacity-On-Demand: Enables modularity within the UPS module itself, providing additional capacity through either software or hardware modules without increasing footprint requirements. Active Eco-Mode : Allows doubleconversion UPS systems to achieve the highest possible efficiencies by transferring the UPS to static bypass during normal operation. Intelligent Paralleling: Improves the efficiency of redundant UPS systems by deactivating UPS modules that are not required to support the load and taking advantage of the inherent efficiency improvement available at higher loads and 750 upgrade to 800 kva and 1100 upgrade to 1200 kva The ability to add capacity-on-demand, either through software or hardware modules, allows power capacity to grow easily with data center needs without additional footprint.

12 Don t Let Desktop Systems Threaten Your Network Security W e like to think employees are committed to maintaining IT security and abiding by privacy and security regulations. But it takes just one bad apple or someone who inadvertently downloads sensitive material from their desktop onto a thumb drive for organizations to end up with a significant loss of intellectual property, severe reputational damage and substantial fines and penalties. The importance of risk management at the network level has long been understood, but risk management at the desktop level has sometimes been an afterthought. With the growing potential for harm, it s time for risk management to extend right down to each individual s workstation. A new briefing document from Emerson Network Power discusses technologies specifically designed to manage desktop security. These technologies can help you substantially reduce risk by: Tightly controlling how users access computers Ensuring IT and system administrators monitor and manage equipment as efficiently, effectively and securely as possible. Control What the User Can Do At the Desktop The key to reducing risk at the desktop is to carefully manage user access to any computer. Using a secure desktop KVM switch is an excellent way to achieve this level of control. This hardware device can control one of the easiest and most common ways for sensitive data to be stolen or inadvertently leaked through USB devices. With a KVM switch, the types of USB devices that can be used with a target computer can be restricted. For example, the switch allows only the desktop s keyboard, screen and mouse to function on a target computer, prohibiting any other USB device from accessing the target, such as a flash or hard disk drive, camera or printer. This effectively prevents unauthorized downloads via the desktop. In addition, the switch can constantly monitor all the devices attached to it, ignoring any access attempts using an unauthorized USB device. Deliver Security with User Transparency While desktop security is growing in importance, it cannot come at the expense of making it harder for people to get work done. Sophisticated KVM switches provide multiple ports in order to support a virtually unlimited array of computers, from PCs running basic applications to high-end graphic applications, for example. With a KVM switch, users need just a single keyboard, monitor and mouse to access multiple computers. An added benefit is that organizations can reduce costs as they no longer need to buy multiple peripherals for each user. In addition, where users need access to a mix of secure and unsecured computer systems, the KVM switch provides a discrete processing path to each computer. 12 Spring 2015 EmersonNetworkPower.com

13 Extend Desktop Security with Remote, Centralized Management For some organizations, it may be desirable to physically separate computer systems from users and to centralize the management of desktop access and control. There are several good reasons to consider using remote centralized management to control desktop access: Reduce risk by placing computers in a secure location and by allowing multiple administrators in different locations to collaborate. Reduce costs as users still need only one set of peripherals to access multiple systems, and they can easily share computers, reducing the amount of systems that must be bought. Centralized remote management requires a high performance digital KVM switch that can deliver an at-the-desktop experience whenever users attach to a remotely located computer. This is particularly important where a high-fidelity experience is crucial, such as in control rooms for manufacturing, utilities, broadcasting and emergency response, or training/ simulation, medical diagnosis and financial trading desks. When considering managing desktop access remotely, look for digital KVM solutions that are platform-agnostic, support a comprehensive range of peripherals and ensure a pixel-perfect user experience. The Emerson Network Power Solution Emerson Network Power provides secure remote management of enterprise network and data center assets regardless of their location, state of health or brand. From data center to control room to desktops, you can trust Emerson s world class solutions to reduce risk, establish security and business continuity, protect against Intellectual Property theft and decrease downtime across the enterprise.

14 Thermal Management Best Practices and Upgrades Learn how to save 30% on efficiency in just 15 minutes Recently, some of our Emerson Network Power Thermal Management engineers toured 15 data centers that serve everything from midsized businesses to Fortune 50 technology companies. In each case they were able to identify significant energy saving opportunities up to 30% savings - by asking just a few general questions. Often, these savings could be realized with the implementation of a thermal management best practice. Below are the most common opportunities they came across. Increase the temperatures in your data center: The old standard was 72 F for return air (the mixture of air returning from computers to the cooling unit) and relative humidity at 50%. Today, you can push return air temperatures as high as 95 F. It is recommended that this be done in small increments to avoid unexpected humidity trouble and to ensure all the IT equipment is functioning properly. This can be done over a few days with little risk to applications and IT equipment. Enlist your facilities manager or vendor partners to assess the safest way to do this. Remember for every 1 F increase in temperature you will save % of your energy costs. Raise chilled water temperatures: For data centers using chilled water, 45 F used to be the standard temperature for water in the chiller. Today, it is possible to operate chillers up to 55 F, reducing energy consumption by 20%. Every degree matters each one degree increase in water temperature reduces chiller energy consumption by two percent. It is important that you work with your facilities manager as raising chilled water set points could reduce cooling capacity in your data center cooling units. Match your cooling requirements to your IT Load: Your thermal management equipment should have variable capacity components (fans and compressors, if applicable) to adjust cooling capacity up and down with your IT load. While constant speed fans are common, they are unable to adjust to a data center s actual performance. A 10HP fan motor uses 8.1kWh of electricity at 100% speed, but only 5.9kWh at 90%, and 2.8kWh at 70%. Savings are significant (and exponential) when fan speed can be matched to the data center s actual requirements. In addition, the compressor is the highest consumer of power in a direct expansion (DX) based system. So the more you can turn it off through economization or reduce its speed through a variable capacity compressor the more energy you will save. HOT AISLE COLD AISLE HOT AISLE Use Hot or Cold Aisle Containment: Containment prevents the mixing of hot and cold air, which increases the temperature of the return air (the hot air being expelled from racks and circulated back to the heat removal equipment). Higher return air temperatures allow heat removal units to operate more efficiently. A 10 F increase in return air temperature can create a 38% increase in cooling unit capacity and an increase in efficiency. Upgrade Your Controls: New controls provide the ability to safely implement and coordinate each of the previously mentioned strategies. When new controls and variable capacity component strategies are added to the operational tweaks described previously, power consumption from cooling in a typical enterprise data center with 500kW of IT load, can potentially drop more than 50%, from 380kW to 184kW or $171,690 in annual energy savings assuming $0.1 per kw hour. That potentially can lower the mechanical PUE from 1.76 to For more tips to increase efficiency, availability and capacity, visit: EmersonNetworkPower.com/ BestPractices 14 Spring 2015 EmersonNetworkPower.com

15 Are Your Rack PDUs Keeping You From Optimizing Power Management? Data center investments are sizable, and each component of the power chain from the building entrance to the rack power distribution is crucial to enabling equipment availability, efficiency and capacity. To ensure you are optimizing your data center power at the rack PDU level, consider these features: Designed for High Availability Is your rack PDU designed to operate in the high temperatures common at the back of the rack? Is it designed to optimize basic power availability? Is it easily upgraded to minimize downtime? Look for: High temperature rating Hot swappable controller card Bistable / normally closed relays Optimized Energy and Capacity Management Does your rack PDU offer accurate and comprehensive metering? Can you remotely control the rack PDU and connected loads? Is it optimized for efficiency? Look for: Metering of key electrical parameters with +/- 1% accuracy Low power consumption Easy access to reporting Simplified Integration with Management Tools A simplified approach to implementation and change management translates to real cost savings and operational advantages. Look for: IP address sharing IPv6 support Support of remote authentication protocols and encryption Compatibility with Racks and Power Chain Is your rack PDU simple to install and move? Look for: Availability in popular voltage and amperage combinations Ability to order and ship pre-installed in a flexible I.T. rack For more information about rack PDUs, visit: EmersonNetworkPower.com/Rack-PDU-Video Resource Gallery Webcasts See our recent webcasts or register at: EmersonNetworkPower.com Emerson Network Power Blog: Learn and be part of the discussion with experts from around the globe.
