You can’t optimize what you don’t know
Look at your equipment, problems, and limitations

Intel Turbo Boost Technology*
Availability and frequency upside of Intel Turbo Boost Technology 2.0 state
depends upon a number of factors including, but not limited to the
following:
- Type of workload
- Number of active cores
- Estimated current consumption
- Estimated power consumption
- Processor temperature
Intel E5-2690-V3 12 Core CPU
Base Speed: 2.6 Ghz
Turbo Speed: 3.5 Ghz
Running turbo is a 35% increase in computing speed
If your poor cabling standards are choking the breathability of your cabinet,
will you ever gain those speed benefits?

Fan Power Loss
Assuming we are working with a typical Dell R630 server
- 7x fan clusters are used to move air from the front to the back of the
server
If your CPU is under heavy load, it is safe to assume those fans will be
pushing up to their maximum RPMs to help keep those processors cool.

When did it become acceptable as an
industry to lose focus on maximizing
processing power and power efficiency
inside a rack?
Aside from the 35% in CPU loss and the
20% waste in power efficiency, the costs
of poor cabling also include:
- Increased labor on basic tasks
- Power risks involved in switch
replacement
- Time-intensive troubleshooting
required
- Locating correct hardware is
challenging
- Cabinets can’t breathe as well
- CPUs don’t get their Turbo on
- Fans need more power to remove
the hot air

Investments in good cabling:
- 1x purchase - $1,000 for color coded
/custom length cables
- 1x purchase - $50 in Velcro
- Initial learning curve
Labor Benefits:
- Decrease in basic task time
- Instantaneous comprehension
- Phantom problems are reduced
- Fewer mistakes
Technical Benefits:
- Cabinet breathes better
- Processors get to Turbo
- Fans run slower (less power and
wear/tear)
- Equipment lasts longer both in
performance and physically
Cost savings can be folded into new
projects as budgets remain flat.
