  • IT managers understand the impacts of insufficient power and cooling in their data centers. You have damage to equipment and downtime, higher operational costs, outages and limited ability to change and grow systems. Latter point is important if you’re selling new systems and services.
  • We just mentioned online UPS technology as a mitigation for overloading circuits, insufficient power conditioning, and insufficient UPS reliability. Let’s take a quick look at what that means. Today, the most commonly used UPS technology is line-interactive. It offers high reliability and is inexpensive, so it’s been the choice of many IT managers. However, it does not fully condition the utility power coming into the equipment, and it will shut down in an overload situation above 110%. The second type of UPS – online double-conversion – is for situations in which your utility power has a lot of variations. The online UPS will transfer to bypass in an overload situation (112%), ensuring continuous power to the protected equipment. Due to Netarx’s focus on Unified Communications, you will most often lead with our Liebert GXT UPS.
  • Now that you have a better understanding of how to mitigate UPS risks, let’s return to our decision points and discuss how to choose the right power protection path for your organization. First, I want to explode a myth about the cost of UPS technologies. Often, you recommend line-interactive UPSs because of their lower up-front price. But I want to show you that their true cost is higher for line-interactive UPSs than for online UPSs. If you recall, our first scenario was about whether to continue replacing batteries in your line-interactive UPSs – which have shorter battery lifespans – or upgrade to an online UPS which has longer battery lifespans, is more reliable, and fully conditions power. Here’s a look at some representative costs of Liebert line-interactive and online UPSs. The top two lines show the relatively higher upfront cost of the online UPS. But you can see that within 2-3 years, your line-interactive UPS will need its battery replaced but the online UPS won’t. At that point, the online UPS cost becomes lower than the line-interactive cost. After 5 years, you make your second line-interactive battery replacement and your first online battery replacement. At that point, hardware costs are just slightly higher for the online UPS than for the line-interactive UPS. But…these are just hardware costs. We’ve already seen how susceptible UPS batteries are to downtime. With the online UPS, you’ll have fewer battery problems, and you’ll incur less cost in ordering, installing and disposing of batteries…PLUS, your customers will get a more reliable UPS that fully conditions power. If you’re replacing a lot of UPS batteries every two or three years, we think it’s time you started recommending online UPSs, like the Liebert GXT.

  • Here’s a quick look at the advantages of a room UPS v. a rack UPS. Rack based designs tend to unfold as equipment is added. Often you end up with 1 UPS per rack and this can be an economical solution up to 15kW Room solutions are built around a single UPS and battery system. Distribution system delivers power directly to individual loads or power strips. Installation is performed by an electrical contractor because the input and output connections are hard-wired terminations, not plugs and receptacles. Room UPSs save space because they are not in the rack and don’t even have to be in the room. Room UPS batteries are of higher quality design than rack UPSs so they last longer, which means much fewer replacements and reliability issues.

    66. 66. <ul><li>Recommended approach </li></ul><ul><ul><li>Line interactive UPS systems have been considered a viable option for some edge-of-network application in the past, but higher availability standards required by IP telephony and increasing sensitivity of network devices have shifted the balance more decidedly toward double conversion UPS systems </li></ul></ul><ul><ul><li>An on-line double conversion UPS supports longer battery runtimes and eliminates the switchover effect that occurs when passive standby and line interactive systems switch to battery. Some communications devices are so sensitive to power interruptions that the switchover can cause a shutdown </li></ul></ul><ul><ul><li>An on-line double conversion UPS with extended battery capacity is required for this application. A communications card in the UPS to support remote management is also a requirement for this application. At a minimum, the system should include a maintenance bypass, although actual UPS redundancy is becoming more common on the edge </li></ul></ul>Scenario 2: Protecting IP telephony devices
    67. 67. <ul><li>Situation </li></ul><ul><li>In the midst of rapid growth at a community credit union, data center capacity and available floor space is maximized. A server consolidation project is undertaken to deliver increased computing and data center performance. Each rack includes a rack-mounted line interactive UPS system. Business growth will likely drive the need for more racks in the future </li></ul><ul><li>Objective </li></ul><ul><ul><li>Take advantage of a server consolidation project to shift from a rack to a room-based UPS system that provides a clear path for expansion as business grows and density increases </li></ul></ul><ul><li>Primary Costs to Consider </li></ul><ul><ul><li>Server downtime can disrupt business operations across the organization, reducing productivity and impacting customer service </li></ul></ul><ul><ul><li>Data center space constraints limit business and IT growth </li></ul></ul><ul><ul><li>As server density increase, UPS capacity must keep pace </li></ul></ul>Scenario 3: Establishing an economical path for growth

Up to about three racks, rack-based protection makes sense, but above that the challenge of managing multiple UPS units – and maintaining multiple battery systems – becomes cumbersome </li></ul></ul><ul><ul><li>A scalable, on-line double conversion UPS would provide cost effective protection today and can be easily expanded to accommodate future growth </li></ul></ul><ul><ul><li>It can be sized to current requirements and then easily scaled with a simple software key as needs change, without having to replace or bring in more equipment </li></ul></ul>Scenario 3: Establishing an economical path for growth
