Billions of arithmetic operations per second
– what´s their value without cabling?

Billions of calculations per second what´s their value
General topics
• 3 pillars of utility infrastructures in data centers
• power supply
• air conditioning
• IT cabling
In view to environmental and economic aspects the first two topics were addressed in detail - „Green IT“, „Energy Efficiency“ but the IT cabling ???

01 Trends in data centers
General topics – IT cabling infrastructure General topics
Cables are the „access to the world“ for the data
- it is the data´s route
to be made available from the outside
… and they are - and they need to be -
everywhere in the data center…
01 Trends in data centers
General topics – IT cabling infrastructure General topics
If we did not have cabling for secure transmission of data …. - no ATM machine without contact to the
data center
- no electronic cash payments - no online banking
- no deals at the stock exchange - no internet availability
and that related to the latest big issues:
General topics – Technology
• „Cloud computing“ and „Big Data“
• …and to guarantee all that on a 7x24 base a lot of considerations
have to be carried out based on hardware and applications.
• .... thus the cabling infrastrucure will be more important as well:
• The applications are being run on servers „somewhere“ .
• The access needs to be optimal.
• not sexy, but mandatory!
General topics – IT infrastructure
• high-speed Fibre Channel applications: 8 GB FC, 16 GB FC, 32 GB FC
• parallel optics applications: InfiniBand, 40 GBE, 100 GBE
to be adjusted with
• cabling design
• essential criterion of design for the IT environment
• no stand-alone topic or subject that can be handled after
the population of the data center,
• synchronization with the hardware population
• challenging length restrictions

ZONE SPECIFICATION SCRATCHES DEFECTS
A: core 0 - 65 µm
PURE® MM No scratches > 2 µm No defects permitted IEC 61300-3-35 MM No scratches > 3 µm Up to 4 defects < 5 µm B: cladding
65 - 115 µm
PURE® MM No scratches > 3 µm Up to 5 defects < 3 µm IEC 61300-3-35 MM No scratches > 5 µm Up to 5 defects < 5 µm
Tidiness - Cleaning of ferrule surface and fiber tip
• cleaning - a well-known topic in fiber optics
since the very beginning of that technology
• up to applications like 2GBit FC:
no strong impact on the performance
• since the introduction of 4 Gbit FC:
cleaning is a mandatory demand!
02 Planning of cabling infrastructures
• What will the future development be in fiber optic technology? • The idea/dream of the all-optical computer comes closer.
• Today: copper circuit paths on the printed circuit boards
03 New developments in fiber optic technology
Products for different applications
Summary
• This development will maybe not change our way of life but it will be a revolution for the data center cabling.
• A challenging perspective for manufacturers and data center operators. • And to answer the initial question:
The calculations are not worth anything
without cabling!
Thank you very much!
