Neptuno Networks is the largest
wireless broadband provider in
Puerto Rico and the Caribbean
that offers Layer 2 and Layer 3
multiprotocol label switching, virtual
private network services, internet
services, voice over internet protocol
services, network consulting,
integration services and managed
services to small, medium, and
major enterprise customers that
require an infrastructure capable
of supporting their mission-critical
business around Puerto Rico and
the U.S. Virgin Islands.
As the largest and fastest growing internet service provider in Puerto Rico and the U.S. Virgin Islands,
Neptuno’s data center had reached full capacity. For several years, they leased co-lo space, but believed
that this method had become counterproductive. In order for Neptuno to realize its full potential and offer
their customers the most reliable service, it was necessary to have complete control of their own data center
and equipment.

In considering space for their data center, Neptuno’s main concern was how to efficiently cool their equipment
without implementing an inefficient and expensive flood cooling methodology. After consideration, Neptuno
decided its data center build-out strategy would be to deploy a pod, two small rows of enclosures that would
be fully contained. Staying within budget and complying with the mandate to maximize energy efficiency
were the driving forces behind the design.
Neptuno purchased a building specifically for the data center where some renovations were made. As
a cost savings, it was decided not to use a raised floor. They turned to the use of a computer room air
conditioning (CRAC) unit and “drop” ceiling as a means to facilitate the flow of air to the pod. The CRAC
unit is a two duct system: one to deliver conditioned air to the cold aisle containment area and the second
to return the heated equipment exhaust. The conditioned air from the CRAC is ducted directly into the cold
aisle containment area constructed of seven foot Polargy® panels and end of aisle doors. The exhaust
returns separately from the enclosures via custom 7' chimneys, which are then funneled into the CRAC’s
return duct. The room temperature is adjusted and maintained as part of the building’s heating, ventilation,
and air conditioning (HVAC) system. Equipment power drops down from the ceiling along ladder rack at
the end of the row and enters each enclsoure throught a cable knockout. Ladder rack and cable troughs
are supported by the top of the enclosures to facilitate the cable paths.
To complete their data center build-out, Neptuno plans to install seven more pods within the same space.

This Computational Fluid Dynamics (CFD)
model illustrates the flow of air throughout
the pod. Conditioned air from the CRAC is
ducted into the cold aisle containment area
(created by Polargy® panels). Exhaust from
the enclosures rise through the chimneys and
is funneled into the CRAC’s return duct.
