Your Success Story


I received my Low Profile cabinet last Saturday and it came in perfect shape.  I'm already loading it with my 3 servers.  Everything fits nicely and I was impressed with the design of this thing.  Heavy as heck but that was expected though.  I liked how the internal rack rails can be adjusted by moving it deeper or shallower by a rail on the ceiling and the floor of this thing.

I was impressed with how it suppresses the noise of my loud supermicros.  I added a layer of dynamat noise suppressers and sound silencing foam on the siding of this box.  This addition dramatically lowers the noise of the servers to almost silent.  This box with dynamat/sound proofing foam really made the servers no louder than a desktop computer.

Monthly Product Special


Since the "hottest" issue in data centers today revolves around effective methods of cooling and thermal management (see the article below on power and cooling), here is an ISC product that fits perfectly with the theme.  As data center cooling is primarily an issue of air conditioning on a macro level, the second line of defense is likely to be at the individual cabinet (micro) level. 
The FC series Thermostatic Fan Control is designed to regulate the cabinet cooling fans based on the temperature in the cabinet.  If the room cooling is sufficient the fan speed (and associated power drain) remain low.  If the room cooling is NOT sufficient, the control unit will raise the fan speed to compensate.  This increases equipment life, reduces service calls, and consumes only as much power as is necessary to control the cabinet temperature.  This device will operate with standard fixed speed fans, and essentially turns them into variable speed fans.

Power & Cooling Must Be A Priority
by CDW Enterprise Power Engineer Andy Lannen
from Processor, February 17, 2006

With increasing amounts of data stored electronically, more processes dependent on computer applications, and more technologies being tied into corporate networks, businesses are far more reliant on technology than ever. As a result, high availability and continuous uptime are essential to a company's operations. Fortunately, the latest generation of power protection technologies offers plenty of sophisticated and economical solutions, making it easy to protect your infrastructure.

A Growing Threat

Blackouts, brownouts, catastrophic sags, and spikes in electricitythe vagaries of the power grid can bring a company's entire IT infrastructure to its knees. The results can range from temporary annoyances to millions of dollars in lost data, equipment, sales, and productivity. "The estimated annual costs of power disturbances are between $119 [billion] and $188 billion a year," says Farah Saeed, program manager for backup power solutions at technology research and consulting firm Frost & Sullivan. “It’s a big problem that affects at least 72% of all U.S. businesses."

Even electricity suppliers acknowledge that businesses don’t always receive pure, clean power. “It cannot be overemphasized that electrical [disturbances] will occur on all typical systems at some point and time," notes utility company Pacific Gas & Electric. “Every facility should consider the impact of electrical disturbances on the various equipment and implement the appropriate mitigation," PG&E advises its customers.

New Power Protection Tools

Fortunately, these mitigative measures are becoming easier and more effective. Vendors of power protection equipment are improving the effectiveness and reliability of their technologies, and today these suppliers match backup and power-generating hardware with intelligent software that makes it easy to protect vital IT resources.

Different Problems, Different Solutions

Comprehensive power protection relies on a number of different types of technologies. Surge protectors level out power spikes, so a sudden boost in power doesn’t overload electronics and burn out components. The workhorse of power protection, the uninterruptible power supply, provides battery backup to keep computers running if electrical power falters or cuts out completely. UPSs can also monitor and manage electrical quality, so sensitive IT components always receive the highest-quality power possible.

UPSs come in a variety of load capacities, measured by their VA (voltage-ampere) rating, a measurement of apparent power. UPSs are also rated by kilowatts, a measurement of real power. In the UPS sizing process, VA is derived by multiplying electrical line voltage by the amp rating of each device or the combined ratings of multiple devices to be connected to a UPS. Single desktop PCs typically require a UPS rated at about 300VA. Networking or VoIP telecom gear might require a UPS rated in the thousands of VA, ranging from 3kVA (3,000VA) to around 15kVA. Large capacity enterprise-class UPSs for centralized server farms and data centers may range from 200 to 500kVA.

UPSs come in three broad categories. The simplest and most economical is the standby device. These units wait in the background as PCs and other standalone devices run off of standard electricity. They don’t intervene unless a problem arises, at which time the UPS’ battery takes over temporarily, long enough for users to save work.

A second category, the line-interactive UPS, constantly monitors the electricity flowing into electronic devices and boosts or levels out the voltage level for spikes and sags. These are appropriate for workgroups and servers.

The most sophisticated UPSs, double-conversion online units, continuously provide the highest-quality power to mission-critical systems. These devices produce optimum sine-wave electricity by converting raw AC power to DC and then back again into AC. These are best suited to large data centers and mission-critical systems that require constant uptime.

The New Wave

Recently, most technological innovation has been in the high-capacity devices that protect workgroups, data centers, and enterprise-wide IT resources. Many of these cutting-edge products extend beyond power management with cooling systems for a comprehensive approach to protecting IT investments. The advanced management software available with these systems can monitor power problems and initiate an orderly shutdown of systems to protect data and equipment. The management programs also perform predictive analyses that continuously monitor conditions and alert IT managers if trouble is brewing.

Workgroup and enterprise UPSs now come in slimmer profiles and rackmount configurations, making them easier to fit into tight communications closets. Meanwhile, many of today’s large-capacity UPSs support “hot swap" capabilities, letting managers buy enough protection for current conditions and then simply plug in additional capacity when needed.

A Kevinism is a funny or intriguing statement or idea from our Vice President of Sales, Kevin Hunt.  Kevin is a big fan of Sandra Bullock, Pizza Inn black olive pizza, and Dr. Pepper (not necessarily in that order).  He is not a big fan of Chinese food, seafood, or other types of "dead" stuff.

Kevin likes to "obfuscate" simple ideas in order to complicate them.  It is usually fun to figure out what he is really trying to say, but sometimes it requires an interpreter.  Fortunately, Robin usually understands what Kevin is saying, and can clear up any confusion.

A recent example is when Kevin was forced into eating Chinese food for lunch.  The best Chinese food in the area is at the Empress of China restaurant in Grapevine.  This is about a 15 minute drive, so we don't go up there very often.  Of course Kevin will do almost anything to avoid eating Chinese, which makes visits there even more rare than usual.  On this particular day, Kevin said they were going to the "restaurant of death" on "Air Freshener Road" and he was sure I would want to avoid this.

There is another Chinese restaurant close by, but I have refused to go there since the Empress of China is so superior.  So I was trying to figure out which restaurant Kevin was talking about.  What threw me off was "Air Freshener Road" so I had to call in a translator.

After Robin heard what Kevin was saying, she was able to clear things up pretty easily. The Empress of China is on Glade Road!

All correct answers will be placed into a pool for a random drawing at the end of the month.  The winner will receive a free 25 foot reel of reusable velcro cable ties (part number MD88-25RLBK), plus free ground shipping.  Send your answers to: 

Jack Burlin

See next month's newsletter for the winner and the correct answer.

Answer from March's Newsletter.

Q:  The Great Pyramid at Giza was originally faced with slabs of Tura limestone.  Now only a small cap at the top of the pyramid remains.  What happened to the rest of the limestone?

A:  In 1169 Saladin became the ruler of Egypt.  Needing a strong fortress to consolidate his power and prepare for his conquest of the Latin Kingdom (Jerusalem), his forces removed the limestone from the great pyramid and over the period 1176 - 1183 built the Citadel, on a hill overlooking Cairo.

There was no winner this month.  Evidently the question was too tough!


When is a toilet

 like a salt shaker?


Part 10  Continued from March

     Here is the table of  the names I have applied to each group of respondents to the survey described in the October issue.  This month we will define the Interior Decorators.

The men who prefer the toilet seat up are: Macho Men
The women who prefer the toilet seat up are: Fairy Godmothers
The men who prefer the toilet seat down are: Men of Leisure
The women who prefer the toilet seat down are: Queens of the Realm
The men who prefer the lid down are: Paleolithic Men
The women who prefer the lid down are: Interior Decorators
The men who have no preference are: Philosopher Kings
The women who have no preference are: Warrior Princesses

Interior Decorators

The second "natural state" of women is to be an Interior Decorator.  Interior Decorators are similar to Paleolithic Men, as they view the toilet as something of larger significance.  Where Paleolithic Men view the toilet as a "tool," Interior Decorators view the toilet as a "showplace."  This gives the Interior Decorator an outlet for her creativity and sense of style.  They like to adorn their toilets.  They will even go so far as to install a "designer" or other trendy kind of toilet.  However, the true signature of the Interior Decorator is if the toilet has a seat cover.  The Interior Decorator uses either the plush seat and tank covers available at places like Wal-Mart and Target, or they buy a cushioned, painted, or appliquéd toilet seats and lids.  If you have any doubt about the number of Interior Decorators out in the real world, just consider the volume of business done annually in designer toilets or designer toilet covers.  You know they sell these toilets and designer seats in traditional male environments like Home Depot!

The Interior Decorator also likes to have shelves over the toilet, but not for the same reasons as the Paleolithic Man.  She wants to put candles, scented soaps, bath oil beads, and other types of "accessories" around the toilet.  Interior Decorators like "potpourri" and wicker baskets to hold magazines.  They also like lace toilet paper holders on the walls, and little facial tissue dispensers (not the usual boxes, but the little square ones).  Don't they fit nicely on the tank lid?

Interior Decorators will go so far as to put towels on the shelves over the toilet, but they will never, ever, stand on the toilet lid.  Would you want to mess up a work of art?  Would you rumple that nice lace seat cover?  Have you no style?

Continued next month with the Philosopher Kings
