Coordinated effort: firm's new data center and headquarters network benefits from suppliers' involvement and assistance

When GMAC Insurance accelerated its St. Louis, Mo., headquarters move from May 2005 to October 2004, network communications manager Wayne Goede found himself in a race against the clock. His challenge: to design and build a new network infrastructure and data center in record time. To complicate matters further, he needed to downsize the data center from 6,000 square feet to 3,700 square feet to provide more space for 1,100 employees, 450 of them in the call center.

"While we lowered our data center square footage substantially, it wasn't great concern for us," Goode says. "There was an advantage in being able to start fresh with new technology.

"There were a number of key design goals that would fit in with our overall infrastructure strategy," Goode explains. "The cable plant for the facility needed to bc totally consolidated. All connections to the desktop locations would be CAT 5e, and the cables would serve no specific purpose. They needed to cross-connect in the data center and wiring closets with standard patch cables to provide service for Ethernet PCs, phones, KVM and extended video."

Additional goals included: installing infrastructure resources that could bc "right-sized" and expanded as needed to address future requirements, minimizing the presence of cables in the data center's raised floor because of limited ceiling height, and powering the entire facility with a backup generator in the event of complete power loss.
One of the staff's initial calls was to Graybar, a provider of supply-chain management services, and a distributor of components, equipment and materials for the electrical and telecommunications industries. The Graybar team provided Goede and his staff with easy access to uninterruptible power supply (UPS), heating and air conditioning (HVAC), network infrastructure and project-management solutions.

For its UPS needs, GMAC Insurance considered both traditional and next-generation options, including the APC InfraStruXure solution, which Goede determined was the right one for the new data center.

Just two years earlier, Graybar had assisted GMAC by providing infrastructure and project-management solutions for the company's new 12,000-square foot primary data center in its Winston-Salem, N.C., facility. Although progressive for its time, Goede says the data center utilized traditional liquid battery technology in its UPS, which included two redundant units so one could supply power while the other was offline for maintenance.

In addition, it required a special environment built to specific OSHA requirements and specialized technicians to maintain the batteries. Realizing these drawbacks, Goede decided the simplicity and security of APC's modular battery design deserved serious consideration.

MODULAR EASE OF USE

"The batteries in the system are, for lack of a better term, consumer-grade batteries," Goede explains. "They are sealed lead-acid batteries that can be safely shipped and handled. The InfraStruXure UPS allows you to pull out a battery module and replace it, with no special equipment and no need to take the UPS offline."

Goede decided to proceed with an integrated UPS, HVAC and enclosure system worth more than $500,000. He worked closely with APC engineers to design the data center system.

"The actual layout of the data center was done in-house," Goede says. "APC, coordinated through Graybar, helped considerably with getting that design finalized. We chose an all-APC solution, with the exception of the open racking, for a variety of reasons, but the biggest is that theirs is an air, UPS, power-distribution-and-enclosure system with all of the parts and pieces fitting together."

The integrated design included HVAC equipment and data center enclosures to complement the UPS. APC's NetworkAIR FM HVAC units contain variable-speed DC motors that speed up or slow down to maintain constant static pressure under the data center floor. In addition, the APC NetShelter VX enclosures feature cable management that allows for organized overhead wiring without ladder racking. Goede says this was crucial for his data center, which had limited ceiling height in its new eighth-floor location.

"One of the key things about the APC system, from a management perspective, is that all the parts and pieces are network attached, and I'm talking Ethernet," Goede says. "They are devices on our data network. They can be monitored and controlled from anywhere on our network, including our Winston-Salem, N.C., help desk. We can see and control internal and external cabinet temperatures, humidity, power load, device status and alerts."
