Managing & streamlining data center top of rack interoperability

Top-of-Rack (ToR) data center designs are credited for simplifying data center deployments

Reduced cabling costs and easy integration of modular rack-and-stack cabinets are key drivers for the adoption of ToR data center designs.

ToR “direct connects” network elements within a rack to a 1U or 2U switch installed at the top of the rack. ToR typically uses lower-cost copper Direct Attached Cables (DACs) to offer cost effective in-cabinet cabling in comparison to designs that run bundles of cables from one cabinet to the next.

Direct connecting switches, servers, and other appliances poses the challenge of interoperability

Interoperability in a ToR environment refers directly to the compatibility of DAC cables connecting devices from different OEMs. Top of Row deployments that mix switches servers, load balancers, or storage appliances from multiple OEMs must address the challenge of interoperability.

Many OEM switches and servers require proprietary cables to ensure compatibility. When plugging an OEM (let’s call this OEM “C”) DAC into a switch, the user expects a plug and play experience, that the switch will see the cable and not present any alarms. No additional workaround commands or special action should be taken.

Luckily third-party solutions are available to solve this interoperability challenge

DACs and AOCs can be programmed in the factory for compatibility to each OEM, additionally, each end can be programmed for a different OEM. The hybrid or multicode DAC solution offers assurance that multi-vendor connections are plug and play.

40G/100G breakout connections supported for multiple OEMs by coded hybrid cables

Each end on these breakout cables can be programmed for a different OEM if the application warrants! Third-party suppliers have experience in programming pluggable cables and transceivers to work seamlessly with OEM switches and servers.

Proline pluggable DAC cables can be programmed for multiple suppliers, giving data center operators a robust set of tools to ensure interoperability in Top-of-Rack environments.
