Consider An Emergency Generator

Written by by Steven S. Ross

Makers of fuel cells, which would replace generators, are just beginning to testrepparttar marketplace, as well. Fuel cell installations promise to be simpler, as there are no noise or pollution issues and units are fairly compact. But costs are unclear.

Data center personnel also worry about maintaining and testing. “Very few companies want to schedule a test once a month or once a week. I don’t think they exist. I never heard of one,” says McHugh. Forrepparttar 145629 average small to medium-sized enterprise, weekly tests are probably unnecessary. However, larger companies may need to test more often.

“In a hospital or nursing home,repparttar 145630 JCHA [Joint Commission on Hospital Accreditation] recommends testing emergency generators once a week. They have to test under load and keep maintenance logs. How important is your data?” says Dauffenbach.

The best test is to use “building mode.” You simply simulate a power outage by cutting off power from outside. “Data centers don’t like to do that,” says Dauffenbach.

A compromise: Use a transition transfer switch. To test, or if you think an outage is coming, turnrepparttar 145631 generator on first, synchronizerepparttar 145632 generator’s output withrepparttar 145633 utility’s power, and then openrepparttar 145634 switch to cut offrepparttar 145635 utility supply.

A more common approach is simply to turn onrepparttar 145636 generator once a week or once a month, whilerepparttar 145637 utility continues to provide power torepparttar 145638 data center. Testingrepparttar 145639 generator that way, without connecting to an external load (the equipment inrepparttar 145640 data center itself), puts extra strain on it. Generator vendors recommend simulatingrepparttar 145641 load by installing a “dummy” load bank. The power can be dissipated with resistive wire (“Think of it as a giant toaster,” says Dauffenbach) or with inductive or capacitative loads. A 10KW load bank can cost $4,000 or more, depending on its type and its adjustability.

APC offers an annual service itself or through business partners worldwide. Underrepparttar 145642 service plan, you can contract to have a test under load done periodically. The APC technicians arrive with their own load bank. “We also recommend testing under real load. Maybe quarterly, on a Sunday, shut down all noncritical processing tasks, checkrepparttar 145643 UPS batteries, and pullrepparttar 145644 plug,” says Hunt.

The emergency generator business is dominated by local firms, working with local design consultants and electrical contractors. Among those suppliers who distribute nationally in addition to APC are Detroit Diesel, John Deere, and Caterpiller. You’ll be referred to a dealer-distributor such as Bowers Power, Covington Detroit Diesel-Allison, and

Figuring The Size

Estimatingrepparttar 145645 generator size you might need involves more than adding uprepparttar 145646 data center’s computer demand. Should you include power for air conditioning? “If you plan being onrepparttar 145647 generator for no more than 20 or 30 minutes, you may not need air conditioning,” says McHugh. “But after 30 minutes, our preference is that at least a portion is put ontorepparttar 145648 generator. A handful of lights is enough.”

If you include air conditioning, you will have to add extra generating capacity to allow for transient loads. Air conditioners, fans, and similar equipment start under load and draw far more than their rated power needs for a few seconds.

How to sell it torepparttar 145649 boss? “It comes down to dollars for everybody,” says McHugh. “What does this cost your company if you have a two-hour outage and you have a half-hour battery? Is this cost inrepparttar 145650 hundreds of thousands? Millions?”


Microsoft's RSS Longhorn Announcement - What It Really Means To You?

Written by Titus Hoskins

Continued from page 1

In that light, it can't be understated that Microsoft's incorporation of RSS into Windows is one of those true 'turning points' that has to be acknowledged. It does change how computers andrepparttar Internet will work.

This is a great step forward in making RSS an integrated and seamless component of computers andrepparttar 145391 Internet.

At last, someone has gotten RSS right.

Not much probably!

Does DOS mean anything to you? If you're like 95% of computer users - probably not much. But that doesn't stop us from enjoying our computers and fully benefiting from DOS. Sometimes complete ignorance is bless.

Unless you're a techie and such technical stuff sets your heart a racing, knowledge of such material is not really required byrepparttar 145392 end-user. People don't have to understand 'HTML' to enjoyrepparttar 145393 Internet.

Likewise, knowledge of RSS is not important torepparttar 145394 ordinary computer or Internet user. Microsoft's RSS Longhorn statement puts RSS where it rightfully belongs, inrepparttar 145395 background, invisible...seamlessly integrated into your computing and web browsing experience.

It will make RSS an integral element of its new operating system which hasrepparttar 145396 code-name Longhorn. It will firmly place RSS intorepparttar 145397 heart of your computing experience, enriching and enhancing it in more ways than even Microsoft is probably aware of yet!

RSS stands for 'Really Simple Syndication' and it has long been associated with blogs and blogging because they are written in RSS or XML format - code like HTML. DOS stands for 'Disk Operating System' byrepparttar 145398 way and itsrepparttar 145399 platform for operating systems on your computer. MS-DOS isrepparttar 145400 most widely used system. Ignorance can sometimes be overrated. Microsoft's announcement of its plans to place RSS features into its next Windows version - due out in 2006 and in servers by 2007 - is truly groundbreaking . You can read more about Microsoft's RSS plans here: Understanding RSS In The Next Windows.

This takes RSS out of just browsers and RSS readers (called aggregators); and gives it much more powerful applications. Most interesting is a new set of applications - Simple List Extensions - allowing web sites to publish feeds containing lists such as a wish list or top 10 list. Should make David Letterman happy!

All kidding aside, for you, these RSS applications will be very beneficial and rewarding. These applications will make browsing, searching and subscribing to your favorite information or sites a lot more easier. You can now take control of your Internet, viewing and accessingrepparttar 145401 information you want to digest.

It has many personal and business applications that will take 'keeping in touch' to a new level. Calendars, events, updates, personal photo albums...can all now be syndicated withrepparttar 145402 new RSS platform.

What's really important about Microsoft's plans, (I believe) isrepparttar 145403 fact that this now makes RSS legit. Lets face it, outside of blogging and a few alert online marketers, RSS is still not understood by most people.

But as stated before, people don't have to understand 'HTML' to enjoyrepparttar 145404 Internet. They don't really have to know about servers, DOS, or even ISPs to get full benefit fromrepparttar 145405 web. Likewise, RSS doesn't have to be known or even understood byrepparttar 145406 majority ofrepparttar 145407 people who will be using it.

But it's helpful that you do understand that for yourepparttar 145408 future of RSS holds many treats andrepparttar 145409 full impact won't really be known for years. Underrepparttar 145410 Creative Commons license, RSS applications could have a far reaching impact on your computing world ofrepparttar 145411 future.

The potential of RSS is enormous. It may even paverepparttar 145412 way for a 'Billion Channel Internet' - where each web site is its own little broadcasting system. An interactive channel that broadcasts audio and video feeds to all interested subscribers.

Microsoft's announcement may just berepparttar 145413 nucleus of such a system. Many components are already in place like podcasting, broadcatching, data feeds, etc. and it's not that great a leap or too fantastical to imagine such a system will exist in repparttar 145414 very near future.

For RSS changes HOW information is transmitted onrepparttar 145415 web...from a passive role to a more pro-active one. Don't come to us - we will deliver.

RSS is also one ofrepparttar 145416 more democratic elements ofrepparttar 145417 web whererepparttar 145418 little guy has a say. It was more than fitting that Microsoft's RSS team met with Dave Winer (Mr. RSS to those who keep a close watch on all things RSS) and asked his opinions on these recent developments.

Ordinary Bloggers have preachedrepparttar 145419 benefits of RSS for so long -repparttar 145420 mantra was becoming a tiresome echo acrossrepparttar 145421 web. No one seemed to be taking RSS seriously.

In that light, it can't be understated that Microsoft's incorporation of RSS into Windows is one of those true 'turning points' that has to be acknowledged. It does change how computers andrepparttar 145422 Internet will work.

This is a great step forward in making RSS an integrated and seamless component of computers andrepparttar 145423 Internet.

At last, someone has gotten RSS right.
