Here are the quick facts: CityNAP is using Extreme Networks aggregation switches -- including the BlackDiamond 20802, BlackDiamond 8800 and Summit X350 -- to create a PCI-compliant environment in its Tier 1 Network Access Point (NAP) in San Antonio, Texas. On the face of it, there isn't such a green story here, but when I actually spoke with CityNAP CEO Don Douglas about why he chose Extreme, energy efficiency and green considerations were absolutely part of the decision.
That's because all of the equipment is DC-powered, which Douglas says is helping the facility save roughly 20 percent of the ongoing operational costs as similar platforms relying on AC power. "DC power, to us, has inherent benefits," he says. The management framework for the switches was also a significant motivator, he adds.
