The Health and the Illnesses of a Data Center, Part 1: Whips

vs

JPE

The Cost of outages

The average cost of data center

downtime across industries was

approximately $5,600 per

minute.

For a total data center outage,

which had an average recovery

time of 134 minutes, average

costs were approximately $680,000

The average reported incident length was 90 minutes, resulting in an average cost per incident of approximately $505,500.

For a partial data center outage,

which averaged 59 minutes in

length, average costs were

approximately $258,000.

Downtime can be even more costly for enterprises with revenue models that depend on the

data center′s ability to deliver IT and networking services to customers-such as

telecommunications service providers and e-commerce companies. The report cited the

highest cost of a single event at about $1 million (more than $11,000 per minute).

Per Emerson Network Power white paper

JPE

It has been said “what can go wrong will go wrong”

•Costs and risks of installing power cables (whips)

in a live data center environment

•Costs and risks of installing power cables (whips) in a live data

center environment

* Compromised Security – non- employees on site, Contractors,

project managers and others

* Time for the installation, availability, tightening of joints, corrections

* What could go wrong? Loose Joints, heat build-up and fire hazard ,

workmanship, flaws, missed items during maintenance checks,

difficulty of putting plus on and off of the system

* Possible Consequences: Loss of power to servers, racks,

rows of racks or sometimes the entire data center.

Using StarLine saves time, money and eliminates unnecessary risks

• The number one risk is outside personnel coming into the data center and this one is

reduced with the usage of Starline

• The 24 steps of whip addition becomes 2 steps with StarLine’s insert and twist

Hot swappable plug-in units

•No interruption to other racks due to circuit changes

•Circuit lead-time goes from up to 4- 6 weeks to minutes

• Risks associated with whip installation are virtually eliminated with StarLine’s fool proof

design

To Optimize using Starline

Time and money, when laying new cables in an existing data center, completion deadlines can be missed for a variety of reasons. Cables too short, broken wires, or damaged insulation is the most common reason.

Looks are deceiving: The fixed load arrangement on this flimsy metal tray creates problems. Unable to be easily adjusted to changes in phase, or amperage requirements

Improving the Design and Performance of the Data Center

The ability to accelerate the changes without creating errors has huge advantages

Introducing systems that have beneficial performance and eliminate the maintenance difficulties and warranty issues.

To Be or Not To Be . . . Do decisions create honey or do you get stung?

Efficiencies can be added to the overall designs – the technology is available to simplify the architecture

Overhead mounting– either

access slot facing side-ways

or access slot facing down.

Under Floor – either access slot

facing side-ways or access slot

Structured Power. All products have strengths and weaknesses.

Of Starline’s many strengths – The most important is the reliability

of the Joint construction. Starline has never had a loose joint on

this system.

Sustainable

These unique features make Starline Track Busway one of today’s most “Green” electrical products

• Flexibility: add/remove circuits in minutes instead of days

• LIVE PLUG IN: add/remove circuits without de-energizing load,

no changes in a live power panel

• Remove under floor cable air dams & reduces bypass airflow by

eliminating cable access holes (brushes, grommets' etc)

• Eliminates many problems associated with power distribution

Starline Efficiencies

Installation Installed very quickly. Mounted on 3m centers with

section lengths up to 6 meters.

Usage The Starline supports all densities, high or low, as well as

increased power density over time.

Reliability

Starline design allows for adjustments to the distribution

layout. The time involved is unmatched by any other

system. Benefits include, operation advantages,

sustainability and infrastructure improvements

Copper utilization Provides the correctly sized system for the power

requirements

Electrical adjustment Can quickly adjust the loads to any server rack.

Power Factor Power utilization is improved by balancing the load.

Floor density The system becomes a lineal panel with branch circuits

along the entire length.

Safety

Unlike traditional PDUs, and raised floor arrangements,

no opening of panels required, no floor panels to

remove.

Power Utility Efficiencies

Starline incorporates the metering into the system

designs to meet the monitoring design criteria based

on the PUE Category

Single point of Failure

issues

The Starline Busway success is extremely high. No

reported failures with joints No operations needed in a
