Forward-looking data center designers and managers realize that, now that the standards are largely defined, migration of Ethernet links from 10 Gb/s to 40 and 100 Gb/s as well as Fibre Channel links from 4 to 8 to 16 Gb/s is rapidly accelerating.
With further interesting wrinkles such as high density 10 Gigabit links (four 10 Gb/s channels combined in a single 40 Gb/s QSFP port and ten 10Gb/s channels combined in a single 100G port), physical aggregation layers, and direct-attach circuits, having a clear and defined plan is not just prudent, it is imperative.
Fortunately a few simple rules for your data center migration plan can reduce much of the uncertainty in this process. Agile design for a flexible data center takes planning, especially to support future migrations in topology and data rate.
Here are our 10 simple rules to help you with your data center migration plan:
Rule 1: Have a plan, develop it carefully, and stick to it!
Rule 2: Develop your data center migration plan using industry standards.
Rule 3: If the standard has options, pick the option that works best for you and stay with it.
Rule 4: Minimize the cabling polarity variants within your infrastructure, and make certain polarity choice does not limit options of the devices you can employ within the infrastructure.
Rule 5: All cabling trunks or components that act as trunks should have uniform polarity.
Rule 6: Once you have chosen your trunk polarity, choose uniform designs and components for 10G, high-density 10G, 40G and 100G channels. Be certain that migration to higher and lower data rates is possible.
Rule 7: Channel designs should account for future uncertainties (e.g. eight or twenty fiber solutions for 100G channels).
Rule 8: Have a uniform practice for MPO pins by data rate for patchcords.
Rule 9: Have a uniform practice for MPO pins on trunks. Trunks should have the same connectors on both ends.
Rule 10: Once you have defined your practices and data center migration plan, diagram each variation and step in your migration and assemble and check a physical model of each to confirm your designs.
Disciplined planning is critical for robust designs. Simple rules for the planning of the fiber connectivity path, polarity and pins help support this discipline both for initial designs as well as the long-term evolution and enhanced utility of the data center infrastructure.
