Time Warner Cable of New York City

With the introduction of high-speed Internet and VoIP phone service, the data center power infrastructure of Time Warner Cable of New York City was not adequately equipped to support the fast growth in services and customer expectations. Commercial space is at a premium in New York City. So as more IT systems were added to support new services, the company was forced to build on the aging power systems, which were not sufficiently able to support the high levels of availability the new services required. A power failure at any point along the data center infrastructure can impact the entire operation—and have serious consequences for the business.

“The Liebert NX easily fit into our current infrastructure. We did not have to rearrange our facilities to accommodate the units. It allowed us to go back into the current, aging power structure and overbuild redundant UPS power in critical spots without having to rebuild the infrastructure that is supported by the existing UPS units, or experience any downtime.”
