Consider An Emergency Generator

Written by by Steven S. Ross

Should you supplement battery-based uninterruptible data center power supplies with an emergency generator? Vendors sayrepparttar question has been coming up with increasing frequency as word spreads about summer rolling blackouts and brownouts and drops in service reliability. Two years ago, 50 million people in eight states fromrepparttar 145629 Midwest to New York lost power for at least 24 hours in one giant blackout.

Amercan Power Conversion and other vendors note that specific localities can have much higher outage rates, either because of building-specific problems or bad weather (lightning strikes inrepparttar 145630 Southeast, for example, or tornadoes inrepparttar 145631 Midwest). In a rolling blackout, power to industrial facilities is often shut down first. New data center managers should checkrepparttar 145632 utilities contract to see ifrepparttar 145633 data center is subject to such utility disconnects.

A Growing Problem

“Deregulation ofrepparttar 145634 power industry has had a real effect on people’s needs to support their systems during shutdowns or to ride through a shutdown,” says Bill Hunt, product line manager forrepparttar 145635 power generation systems group at APC. Despite that, he says, customers typically admit that they’ve considered a backup generator but rejectedrepparttar 145636 idea because ofrepparttar 145637 design work required.

“A UPS provides clean power, guarding against surges and drops,” says Dan McHugh, project manager at PTS Data Center Solutions. “In order to provide longer-term power, you’d need racks and racks of batteries. A generator allows you to be out two to three days, so you’re not losing money.” PTS is a consulting firm that does design work, construction, or construction management.

Says Hunt, “Our small and medium business customers started to come to us looking for longer runtimes. It used to be seven to 10 minutes, and now they were asking for two hours or more.” A well-designed emergency generator can run for days.

A data center with seven to 12 racks full of equipment needs 20KW to 40KW to stay up. The cost, installed with proper electronics for testing as well as for emergencies, with noise and air pollution controls, is typically $35,000 to $40,000, vendors say?after warning that installation costs can vary enormously.

Vendors say that units up to 20KW, on a concrete ground-level pad, are standard enough in many circumstances to be “ordered onrepparttar 145638 phone,” in Hunt’s words. But anything larger will require some specialized expertise and more careful configuration. Local electrical and HVAC contractors can point data center personnel inrepparttar 145639 right direction.

It is little wonder that data center management worries aboutrepparttar 145640 cost. But over time,repparttar 145641 price doesn’t seem as high. “That’s aboutrepparttar 145642 same as an extra 45 minutes to an hour’s worth of batteries,” says Hunt, “amortized over about 10 years.” Asrepparttar 145643 kilowatt requirements rise,repparttar 145644 generator option gets cheaper by comparison. But site problems, especially lack of space outsiderepparttar 145645 building to pour a concrete pad forrepparttar 145646 generator and noise-attenuating enclosure, can inflaterepparttar 145647 cost quickly.

Michael Dauffenbach, industrial sales region manager for Katolight, saysrepparttar 145648 generator itself might be only a third or halfrepparttar 145649 total cost. “A 15KW gas [typically propane] unit’s list price is about $10,000,” he says, “and diesel is aboutrepparttar 145650 same.”

As capacity increases, diesel prices rise more slowly than gas. At 250KW, diesels cost about $45,000 and gas $90,000, again, forrepparttar 145651 generator alone. APC doesn’t see propane or natural gas as practical above 150KW. About a quarter ofrepparttar 145652 units APC sells run on gas, withrepparttar 145653 rest on diesel fuel.

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

Written by Titus Hoskins

Will Microsoft's Incorporation of RSS into its next Windows version (code-name Longhorn) due out in 2006, finally give RSSrepparttar respect it deserves? What does it really mean for RSS? More importantly, what will it mean to You as a Computer and Internet User?

What Will Microsoft's New RSS Windows Mean To You As A Computer And Internet User?

Nothing and a whole lot!

That's if Microsoft gets it right. First impressions appear to be very promising and all indications show a much more powerful RSS system, neatly integrated intorepparttar 145391 next version of Windows. Could this finally meanrepparttar 145392 'coming of age' for RSS?

But what does RSS mean torepparttar 145393 average computer user at this moment in time? Will people get RSS? Does Microsoft have an education project on their hands with RSS?

Not Really!

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 makes your heart skip a beat, knowledge of such material is not really required byrepparttar 145394 end-user. Fortunately, people don't have to understand 'HTML' to enjoyrepparttar 145395 Internet.

Likewise, knowledge of RSS is not important torepparttar 145396 ordinary computer or Internet user. Microsoft's RSS Longhorn puts RSS where it rightfully belongs, inrepparttar 145397 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 145398 code-name Longhorn. It will firmly place RSS intorepparttar 145399 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 145400 way and it'srepparttar 145401 platform for operating systems on your computer. MS-DOS isrepparttar 145402 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 giving 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 145403 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 145404 new RSS platform.

What's really important about Microsoft's plans (I believe) isrepparttar 145405 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 145406 Internet. They don't really have to know about servers, DOS, or even ISPs to get full benefit fromrepparttar 145407 web. Likewise, RSS doesn't have to be known or even understood byrepparttar 145408 majority ofrepparttar 145409 people who will be using it.

But it's helpful that you do understand for yourepparttar 145410 future of RSS holds many treats andrepparttar 145411 full impact won't really be known for years. Underrepparttar 145412 Creative Commons license, RSS applications could have a far reaching impact on your computing world ofrepparttar 145413 future.

The potential of RSS is enormous. It may even paverepparttar 145414 way for a 'Billion Channel Internet' - where each web site is its own little broadcasting system. An interactive channel that broadcasts audio and video to all interested subscribers.

Microsoft's announcement may just berepparttar 145415 nucleus of such a system. Many components are already in place like podcasting, broadcatching, data feeds, etc. and its not that great a leap or too fantastical to imagine such a system will exist in repparttar 145416 very near future.

For RSS changes HOW information is transmitted onrepparttar 145417 web...from a passive role to a more pro-active one. Don't come to us - we will deliver.

RSS is also one ofrepparttar 145418 more democratic elements ofrepparttar 145419 web whererepparttar 145420 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 145421 benefits of RSS for so long;repparttar 145422 mantra was becoming a tiresome echo acrossrepparttar 145423 web. No one seemed to be taking RSS seriously.
