Today’s reliance on IT has created a larger demand for efficient and resilient data center infrastructures. IT managers are seeking data center providers where “redundant everything” is the need. One of those requirements will revolve around power coming into the facility. One of the basic requests for a data center will be to have a dual feed environment. Today’s providers often offer “dual feed” power supplies – but does that really mean two independent power feeds?

“The Truth about Dual Power Feeds” is a white paper from Data Foundry that examines the reality around several different configurations of services which are often promoted as dual feed. Furthermore, this whitepaper examines how each offering can actually be delivering a drastically different level of robustness and failure risk.

In understanding the differences, the term dual feed actually has quite a bit involved in the design.

  • Location of switches, substations, and transformers.
  • Types of UPS systems in place.
  • Utility locations and availability.
  • Differences in quantity, placement, and redundancy.

The Truth about Dual Power Feeds helps data center administrators better understand the needs around power deployment. In examining the topic, this white paper outlines the pros and cons of four important classes of power feed classifications:

  • Class 1 – Single Feed
  • Class 2 – Single Substation
  • Class 3 – Dual Substations
  • Class 4 – True Dual Feed

By having a clear understanding of the key identifiers and components within each class of power feeds, administrators are able to make better data center decisions. Click here to download The Truth about Dual Power Feeds to see the challenges and benefits of working with dual feed technologies and how this affects your data center.
