Dell’s management was hoping to add a new high density computing zone to Dell’s 15,480 square-foot data center in Austin, Texas. The data center housed 577 2-post cabinets containing nearly 5,000 networking and storage equipment elements. The data center had non-uniform distribution of IT loading with high-density equipment concentrated on one side. Despite the presence of 25 Leibert 740C scooped CRAC units (capable of cooling 2.7 MW of waste heat), a handful of servers were overheating as determined by their manufacturers’ specifications. The site’s power usage effectiveness (PUE) of 1.86 was reasonable, but higher wished for. Could simulation lead the way to eliminating hotspots, reducing inlet temperatures, improving efficiency and increasing computing capacity in Dell's data center?
“The power density of IT equipment increases rapidly, but modifying the supporting infrastructure of the data center is expensive and complex. Before you rearrange your data center, you had better know what you are doing. 6SigmaDCX allows you to test your ideas without expensive data center downtime.”

Chris Noland, Cisco Systems Engineering Manager, had a goal to improve cooling system efficiency for a data center on Cisco’s San Jose campus. There were many challenges to overcome as the facility has been in operation since 1999 with limited considerations for efficient operations. In all, a total of seven different product groups manage the IT configurations and Chris’ group manages the room. Historically, none of these groups had any responsibility for efficiency. These circumstances led to suspected areas of inefficiency such as cooling oversupply and mixing of supply and return air. Cisco estimated a cost savings of $200,000 annually but was unsure if this was achievable due to a lack of data related to the cooling architecture. In reality, any cost savings would be viewed as a win.
“When it comes to data center efficiency, there are few larger gains than improving the heat removal architecture. The Virtual Facility is the best tool I've seen to tie together cooling, availability and efficiency in one analytic model. A very valuable tool for many data center operations”

When CBRE’s global finance customer wanted to improve energy efficiency, they selected the Virtual Facility (VF) to make it happen. Developed by Future Facilities, the VF safely assessed and evaluated a wide range of improvement plans, saving the bank an estimated $10+ million through combined efficiency and capacity gains in a single data center.
“This was the first time that the client had been able to reliably map out the consequences of IT changes without first making those changes in the actual facility.”
