Since its inception in the mid-2000s, the modular data center market has exploded into a $13.1 billion industry that's poised to more than triple in value by 2022. Modularity standardizes the most expensive hardware components and disaggregates everything else. Individual modules can therefore be swapped out at a fraction of the cost of replacing the entire unit. 

As a natural outgrowth of this trend, the rack power distribution unit (PDU) has officially gone modular. Here's what that looks like:

The Modular Components

Chassis and Cord: Mainstays

  • The receptacles, wire, and chassis represent 60 percent of the PDU investment; this is the part that doesn't change.
  • A universal PDU-side power-cord port enables easy switching of facility-side cables for compatibility anywhere in the world.

Monitoring Intelligence: Here today, gone tomorrow

  • From basic metering to remote, outlet-level switching, hot-swappable ports let you customize power monitoring. 
  • Interchangeable Monitoring Devices (IMDs) can be retrofitted in the field to provide real-time environmental monitoring, along with other technology upgrades.

Fault-Tolerant Daisy Chaining: Modulate at scale

  • Easily deploy up to 40 intelligent PDUs on one network port with Ethernet-enabled daisy chaining. 
  • With Rapid Spanning Tree Protocol (RSTP), a series of connected PDUs maintain redundancy in a bi-directional network loop and utilize two network ports. 

Plug-and-Play Data Center Infrastructure

The modular rack PDU is a lean, mean modular machine. The costliest components don’t need to be swapped out for the duration of its lifecycle. As your facility changes, different types of power and environmental monitoring IMDs can be added and removed. Not to mention, intelligent PDUs can be deployed into an existing series of daisy-chained power strips with relative ease.  


There's no doubt that the modular data center's best days are ahead of it, but it's off to a pretty good start.
