Data Centers from Edge to Cloud
We design, build, and operate data centers that are great for companies and their people... but better for the planet
Core challenges in the data center cooling process can be grouped in the following categories:
- Lifecycle Costs
Due to these challenges, proper server room cooling requires specialized air conditioner equipment designed specifically for the unique requirements of the environment. In general, there are two (2) approaches to server room air conditioner – water-based and refrigerant-based (DX).
Also, there are typically two (2) primary stages of server room cooling systems. The first is the heat removal stage. This is characterized by the CRAC or CRAH that sit within the server room and whose purpose is to cool the server room by removing the heat from it. The other is the heat rejection stage. This can be the condenser, dry-cooler, cooling tower, and/or chiller equipment whose purpose is to reject the heat removed from the server room into the ambient (outside) environment.
Additionally, there are typically two (2) classes of server room cooling systems. The primary is precision air conditioner equipment that is purposely built for server room operation in that has a high sensible heat load, tightly regulates temperature, is designed to operate 7×24, and can provide humidity control. The other is comfort-cool air conditioners which are made specifically for people cooling, but have been utilized in server room cooling scenarios due to their lower capital and installation cost.
The proper operating environment for a server room is established by ASHRAE. Over the years, ASHRAE has slowly adapted its guidelines to the much faster changing state of the IT industry with respect to server room cooling requirements. Following is the current ASHRAE server room cooling guidance:
Server equipment generates and dissipates heat exactly equivalent to the amount of power it consumes from the source that feeds it. However, properly sizing server room cooling takes into account more than just the heat generated by the IT infrastructure. Calculating the heat load must include losses in power protection and distribution, lighting, heat gain through walls, floor, windows, and/or ceilings, and even the people that will be in the space.
Further, proper server room cooling system design takes into account more than just the mathematical comparison between the heat load demand of the room and the cooling capacity of the air conditioner equipment serving it. Proper server room cooling system design must also account for the layout and configuration of the cooling equipment, the IT load components, racks, and/or cabinets as well as the obstacles affecting air flow. As such, beside a numerical tabulation to select the ideal server room cooling equipment, PTS uses a computational fluid dynamic modeling to verify the design assumptions for the server rooms cooling system under both normal operating and failure scenario conditions.

DICE National: Data Center Operations and Cooling Digital Summit recording available: Designing for the Edge with Pete Sacco, President of PTS Data Center Solutions, and other Data Center Professionals.
Webinar Data Center Development Innovation for the New Age of Facilities. Learn how end users and providers are determining cloud or on-prem strategies for new facilities coming online, how fully integrated edge developments have changed the need for on-prem solutions, who are changing their migration to the cloud and where the opportunities are for expansions.
The average enterprise data center costs between $10 million and $12 million per megawatt to build, with costs typically front-loaded onto the first few megawatts of deployment. Seasoned data center builder Peter Sacco, founder and CEO of PTS Data Center Solutions, claims that it is possible to drive down costs by around 25 per cent or more, simply by being more disciplined on design.
Pete Sacco (Founder and President, PTS Data Center Solutions) and Jamie Funk (Head of Sales for Verticals at Bloom Energy) talk to Dan Loosemore of Data Center Dynamics about future-proofing the modern data center using PTS’ Data Center Reimagined approach and Bloom Energy’s fuel-cell and micro-grid solutions.
