| Managing
Extreme Heat Cooling Strategies
for High-Density Computer Systems |
| As
computer manufacturers pack more
and more processing power into
smaller packages, the challenge
of data center cooling becomes
more complex – and more
critical. New servers and communication
switches generate as much as ten
times the heat per square foot
as systems manufactured just ten
years ago & conventional cooling
techniques are not enough. |

| The
Anatomy of a High Availability
System Configuring the New Data
Center for the Ultimate in Systems
Availability |
| For
the past several decades, Market
Intelligence has monitored the
shift away from early mainframe
orientation toward an exploding
PC - and workstation - based market.
Yet today, we are experiencing
a re-shift back to a centralized
environment. The migration back
to a more protected environment
is driven by a growing demand
for systems availability, often
nothing less than 7x24. Demands
on servers, e-commerce/internet,
and data/telecommunications equipment
have made the "no down time"
operating parameter the goal.

| Lifecycle
Costing for data center: Determining
the True Costs of Data Center
Cooling |
Experts
estimate that the average “design”
life of a data center is 10-15
years. During that time, equipment
will change three or four times.
With each change of equipment
comes more demand for power. And
more power means more heat. This
makes evaluating cooling systems
for the data center a significant
challenge. Synchronizing technology
equipment with power, floor space
and proper cooling — and
doing it all cost-effectively
— takes serious analysis.

"Mission Critical Applications"
in your Data Center Outrunning
your System Protection? |
| Corporate
datacenters – even small
ones – are supporting more
critical business applications
such as integrated data/voice/video
networks, real-time interaction
and e-commerce support for Web
sites, and sophisticated knowledge
management systems. The backbone
of these applications is the new-generation
server switch capable of managing
gigabitscale information loads.
These rack-mountable switches
can become part of a scalable
support for a wide range of company
and customer-facing functions.
But the increasing sophistication
comes at a cost: vulnerability
to power anomalies that can cause
lost packets, switch outages and
other persistent problems. |

The ABCs of UPSs |
|
What does it cost you when a computer
freezes, loses data, or "hard
crashes"? A recent study projected
the cost of such interruptions
at more than $4 billion annually,
with the annual lost productivity
of workers estimated at 37 million
hours. The major cause of the
costly break in computer services
was identified as power disturbances.

| The
Four Classes Of Power Solutions
|
| The
following is an overview of the
four basic types of power solutions
that address the range of current,
often complex power protection
needs. Each type is appropriate
for some network configurations
and wrong for others. Large networks
may even require a combination
of types. The best solution is
one that most closely matches
user needs, based on such criteria
as load size, application criticality,
the proximity of the protected
equipment, and the nature of the
power problems. |

| Better
Network Management Through SNMP
|
| As
we move past the middle of the
decade, the trend continues away
from host-based to clientserver
systems. It's no secret this operational
migration has caused as many new
network management problems as
it has answered . Intensified
requirements come from all directions:
more nodes, more uptime, more
communications, more flexibility,
more shared resource availability,
more desktop capabilities, more
reliability. More everything except
the standards that have seemingly
been left behind in the protected
environment of the data center.
Enter the Simple Network Management
Protocol (SNMP) framework of interoperable
solutions for managing networks.

| Are
Your UPS System Batteries Really
Ready to Load Test? |
| In
a critical power application,
stationary batteries should be
properly installed, inspected,
commissioned and tested before
being placed into full service.
Unfortunately, some installers
hurry through inspections and
the load test is performed before
the batteries are properly prepared.
This paper outlines the correct
way to prepare batteries for load
test and explains the importance
of each step. |

| Heat
vs. Hot Air |
| This
paper gives a general explanation
of how heat and altitude affect
UPS operation. Also included are
tables showing how to compensate
for high altitude (more than 4,000
feet above sea level) in specifying
power systems. |

| Harmonic
Current Reduction Techniques For
Computer Systems |
| While
standards to limit the generation
of harmonic currents are under
consideration, harmonic control
today relies primarily on remedial
techniques. Passive filters are
the most popular, but require
careful application, can be expensive,
and may produce unwanted side
effects. Active filters are costly
and not widely available. Harmonic
currents can be controlled by
carefully selected special purpose
transformers, |

Transistors Are Not Greated Equal:
The Advantages of IGBT's in 3-Phase
UPS Products |
| In
recent years, manufacturers have
been changing over to transistorized
inverters in their low-tomedium
power Uninterruptible Power Supply
(UPS) products. This paper studies
the types of power semiconductors
presently in use, explaining the
advantages and disadvantages of
each. |

| Field
MTBF Numbers: What do they really
mean? |
| The
Liebert Series 600 has established
itself as the most reliable static
Uninterruptible Power System in
the industry. Our sales literature
speaks of critical bus MTBF in
excess of one million hours. This
paper explains where these numbers
come from and what they mean to
the customers buying the product.

| K-Factor
Transformers and Nonlinear Loads
|
| Harmonic
currents generated by nonlinear
loads can cause problems in the
power system. Transformers are
particularly vulnerable to overheating
and premature failure. To protect
against transformer overheating
caused by harmonics, designers
can specify derated equipment,
i.e., oversized transformers that
will run at a fracton of their
rated capacity, or K-factor transformers
spedfically designed to accommodate
harmonic currents. |
