Prior to writing the paper for the Unit 5 project review the suggestions that I provide below. Keep in mind that these projects are more complex so that you learn about technology and learn how to communicate your knowledge to others. To provide a proposal(s) means to supply a specific solution to the firm based on the scenario. That solution must explain why the device(s) chosen will solve the problem including: (1) which systems are most critical, (2) which systems will receive all of the devices, or the most powerful device(s), (3) which systems will not receive a UPS solution, (4) justification for the solution. Some solutions providers (found on the Internet) separate their solutions by price, capacity, and application. For a professional quality paper, the solution might include technical specifications for the device(s), i.e.: the capacity of the device. It could include an explanation for how the capacity is determined….total watts used. One way to determine this is found in the explanation to follow. If you are estimating power requirements, that is fine because you don’t know the exact capacities of servers in this fictitious environment. However, you could do a very quick search on Dell, IBM, or another Website for server information which would include their wattage. After 5-10 minutes on the Internet, I found a number of postings about Dell server voltage ratings and information on wattage can be found on the Dell site under server specifications. The specific wattage solution provided below is used to help you determine the number and type of UPS devices once you have wattage/amp rating. Make a reasonable guesstimate based on what you are given in the scenario…100% accuracy isn’t possible, nor is it expected. When choosing a UPS device, make sure that you pick one which will be able to handle the demands of everything you want to have protected. UPS suppliers will normally help you work out what level of device you need but if not, you can work it out yourself with some simple math. Next to the power socket on Macs, PCs and virtually all other IT equipment you’ll find the item’s amps rating. Multiply that by the main voltage and you’ve got the VA rating; volts x amps = VA. (VA is also commonly called watts, although an electrician will point out that there’s a difference between the two.) If necessary, divide the VA figure by the UPS device’s capacity and you’ll have the length of time its battery can maintain those items on its own; VA / capacity = uptime. 1 To find Your Equipment's VA Ratings: Look on the nameplate of your equipment. If the equipment is listed in amps, multiply the number of amps by the input voltage to determine VA. (Example: 1 amp × 120 = 120 VA). Once you have added up the VA ratings of all your equipment, choose a UPS System with a VA rating equal to or higher than your total. You may want to consider selecting a UPS System with a higher VA rating to allow for future growth of your system. 2 A specific price must be noted that allows for the distinction between the two proposals. This means that you must find more than one source and provide a reference to those sources in your paper. You may not use Tripp-Lite as a source now that it has been provided for you. Your solution may simply be an estimate based on some research that you do to determine some approximate wattage for servers. Do the best that you can. The specific wattage solution is used to help you determine the number and type of UPS devices. Make a reasonable guesstimate based on what you are given in the scenario…100% accuracy isn’t possible, nor is it expected.
