infrastructure • Best practices for migrating to 40 and 100G Ethernet • Next steps for data centers


What You’ll Learn:

With the ratification of new industry standards and increased demands on data center throughput, 40/100G Ethernet will be an integral component of the next generation data center.


Introduction


Why are data centers migrating to 40/100G Ethernet?

The world revolves around digital data. According to The 2011 IDC Digital Universe Study sponsored by EMC:

“The world’s information is doubling every two years. In 2011 the world will create a staggering 1.8 zettabytes. By 2020 the world will generate 50 times the amount of information and 75 times the number of ‘information containers’ while IT staff to manage it will grow less than 1.5 times.”

(1,000,000,000,000,000,000,000 bytes = 10007 bytes = 1021 bytes)



Virtualization: the double-edged sword. Server virtualization calls for fewer, more efficient servers, which translates to fewer server connections. And because there are fewer connections, is it important that these connections work properly.



Decreasing tolerance for downtime. Network downtime measured for user experience and business needs costs an average of $5,600 per minute.



Managing capital expenses. While migrating to 40/100G Ethernet creates an up-front capital expense, it saves data centers in the long run by future-proofing infrastructure. Meaning: upgrading now will mean fewer upgrades in the future.



A change in data center cabling standards. In 2010, the Institute of Electrical and Electronics Engineers (IEEE) published the standard for migrating to 40/100G Ethernet. The standard, titled 802.3ba, sent a clear message to data center operators and manufacturers alike that the road to 100G was imminent, and the industry needed to start preparing for this migration as soon as possible.




Factors in preparing for 40/100G Ethernet migration

Link Distances and Loss Amounts: loss budgets decrease when data center speeds increase • Added mating points are the main reason for dB loss in the data center (not distance) • Look for “maximum” instead of “average” dB loss rates when purchasing cables to minimize dB loss over mating points


Factors in Preparing for 40/100G Ethernet Migration



• Cabling Infrastructure

Design • Point-to-point versus

structured cabling system • Structured cabling system

can grow and move as data center needs change and throughput demands increase

• TIA-942 data center standard is recommended



• Connectivity Options: Option 1

• Uses long-haul (LX) transceivers with single-mode (SM) cabling

• Data is transmitted via serial transmission • This setup is typically not used in data centers

• Built for long distances • Very expensive because of the lasers used in LX

transceivers



• Connectivity Options: Option 2

• Uses short-haul (SX) transceivers with multi-mode (MM) cabling

• Data is transmitted via parallel optic transmission • This setup is typically used in data centers

• Ideal for shorter distances • More cost effective



• Connector Types

• LC connector • MPO-style connector



• Fiber Types – OM3 or OM4


What About Copper?

• Consider: • Costs • Transmission • External Interference

• Conclusion: copper cabling is better for the edge of the network


Conclusion Data centers are experiencing the most significant

change in cabling infrastructure since the introduction of fiber optic cabling. No longer is it a question of if, but when, data centers will migrate to 40/100G Ethernet. Installing a high-performance, fiber optic structured cabling system is essential to a successful migration.


Next Steps 1. Determine your current and future data center needs, including

throughput demand, data production rates and business-driven objectives. In what ways does your current data center infrastructure support and/or fail those needs?

2. Use this information to determine when your data center should migrate to 40/100G Ethernet.

3. Map out your current data center infrastructure. 4. Use this map to create a plan for the hardware and cabling

infrastructure upgrades necessary for migration. 5. Create a plan for migration, including internal communication strategy,

budget, timeline and roles and responsibilities of those involved.
