You
don't have to don a pair of Ran Bans and white polyester suit and then
strut around your server room like Tony Manero (a la John Travolta in
Saturday Night Fever) to look cool. But there are certain items anyone
who's anyone in IT simply has to have. These items will not only make
you look cool, they will also deliver the goods in terms of keeping
server room temperatures low and reducing the power load too.

A Cool Server That's Hot
Sun
has re-established some of its earlier market cachet via its Sun Fire
T1000 and T2000 servers. These "CoolThreads" models are likely the key
reason the systems vendor was able to take back third spot from Dell in
the server big leagues. And with more than $100 million in sales in one
quarter, the UltrSPARC-T1-based servers may well be destined to join
Cabbage Patch Kids, Furby and Tickle Me Elmo as the Holiday Season toy
everyone must have. A big part of the popularity of the Sun "Model T"
is the sheer volume of processing power available within a small power
footprint. While other vendors boast about dual cores, Sun is way ahead
in processor architecture.
"These
UltraSPARC-based servers have chips with eight cores, each with four
threads," says Ted Gibson, an engagement architect at Sun Microsystems.
"Its chip uses the same amount of power as a small light bulb 70
watts."
The
T1000 is the less expensive of the two. Those wanting to try it out
will find the entry price for this 1U rack server to be around $3,000,
Gibson said.
Cool on the Cheap
"The
SC440 uses Xeon 3000 series chips," says Ryan Franks, product manager
of Dell's PowerEdge Server Group. "It is typically used for file/print,
e-mail, Web and application server purposes."
Racks Can Be Cool
A good
server deserves a classy cabinet. And plenty around look the part and
do the job. Knurr AG of Germany has a range of rack systems starting
with the Knurr Miracel with an aluminum frame for $1,100. It also
offers a mesh version for around $1,500. Instead of having a glass door
at the front and a steel door at the rear, it provides an aluminum mesh
that permits 80 percent of the air to flow through to improve
air-cooling efficiency. And for those looking for the top of the line,
the Knurr Cooltherm cabinet has a water-cooled design for high-density
environments for a little over $10,000 per rack.
According
to Knurr sales manager Rod Arnold, Barclays Bank in the United Kingdom
and the University of Dresden in Germany use Cooltherm to house
mission-critical servers.
>"Barclays
successfully tested Cooltherm with a load of over 30 kW," says Arnold.
"Systems OEMs charge a lot more for their cabinets, yet they are less
flexible when compared to the range of engineered-to-order models that
we offer."
HP,
too, has gotten into the liquid cooled rack business. The HP Modular
Cooling System (MCS) ties in to the building chilling system to bring
cold water right beside an HP 10,000 GT rack. The MCS is an additional
box weighing about 900 pounds (without water), which blows chilled air
directly onto the servers in the 42U rack it serves. It costs about
$30,000.
"MCS
provides 20 gallons per minute of water chilled to 5 or 10 degrees
Celcius," says Richard Brooke, an HP enterprise infrastructure
specialist. "It can handle a 30 kW load."
Double-Secret UPS
The HP
rack mentioned above comes with build in Uninterruptible Power Supply
(UPS) features. But many racks need UPS support. Liebert of Columbus,
Ohio, for example, has a product line that ranges from 2U to the 1000+
kVA systems that protect massive facilities.
"With
the number and density of servers on the rise, you need better ways to
distribute power to and manage power within racks," says Peter Panfil,
vice president of engineering at Liebert. "Our UPS systems feature
online double-conversion UPS technology to provide protection against
all types of power disturbances."
Liebert's
PowerSure PSI is a 2U line-interactive UPS in sizes from 1000 VA to
3000 VA. The 3000 VA version starts at around $1,700, and the 1000 VA
model is around $500.
Tile We Meet Again
Purse
string issues may limit the options for taking the the heat out of the
server room, but possibilities remain. Take the subject of the floor
tiles. Perforated tiles are generally placed in the cold aisles to
bring cold air to the heat load. Most people don't give them a second
thought.
But
Tate Access Floors of Jessup, Maryland, has found out with a new slant
for this everyday item. Its GrateAir tile is an aluminum grate that has
twice the open area of regular tiles. That translates into a
300-percent increase in cubic feet per minute of cold air into the
server room.
quot;GrateAire
can be used in new and existing server rooms," says Ralph Manion,
national sales director of Tate Access Floors. "Although it costs 15
percent more than regular tiles, it pays for itself in terms of reduced
power and cooling bills."
Inexpensive SAN?
Inexpensive
SANs have been touted for some time, but Zetera's Hammer Z-Series
really delivers. It strips away the need for expensive Fibre Channel
technology, making implementing a SAN a piece of cake.
"Most
people who don't have a SAN think they are too complex and too
expensive to implement," says Jeff Greenberg, senior director of
product marketing at Zetera. "All you need to implement the Hammer
Z-Series is an Ethernet port."
Each
unit has a throughput of 80 MB per second. Any computer on the network
can access the unit and store or retrieve data rapidly. A small desktop
version contains 1 TB of capacity and costs $1,299. Larger versions are
available. The data within is protected using RAID.
Update Your Image
Tony Manero was the king of the Brooklyn dance floor, he came to
realize that bigger things awaited him across the water in Manhattan.
Similarly in the server room, what once wowed visitors, soon becomes
staid and unexciting.
The
items listed above are one remedy. Not only do they offer something new
to talk about, but most of them will also enable you to do more with
less or make a big dent in your power demands.
