Speeding up the net

App State’s Dr. Abdelbaset Hamza studies efficiency in internet data centers

Traditional data center designs have servers set up in rows and racks, with cables connecting devices. Appalachian State University’s Dr. Abdelbaset Hamza and his App State research team are simulating different configurations — such as this geometric cell-based design — with the goal of improving efficiency and speed of data transfers. Hamza received a nearly $175,000 National Science Foundation grant in support of the project. Illustration provided by Dr. Abdelbaset Hamza

“The (simulation) tool can help us compare the performance of proposed designs, resulting in higher speed, more flexibility and more efficiency.”

BOONE, N.C. — Answers to Google searches, information on websites, files stored in the cloud, and music and movies for streaming — all resources at people’s fingertips as part of their daily lives — are housed in large data centers all over the world. These warehouse-sized centers, filled with thousands of computer servers, require massive amounts of electricity and effort to operate.

“The (simulation) tool can help us compare the performance of proposed designs, resulting in higher speed, more flexibility and more efficiency.”

Dr. Abdelbaset Hamza is leading a team at Appalachian State University to study ways to make the transfer of information in data centers more efficient. His goal is to improve and speed up performance, as well as reduce the carbon footprint and impact of data centers on the earth’s resources.

Hamza, an assistant professor in App State’s Department of Computer Science, received a $174,956 grant from the National Science Foundation’s Directorate for Computer and Information Science and Engineering to fund this project — which began in February 2020 and will continue through early 2022.

Traditional data warehouses contain many rows and racks of computer hardware, connected by a complex system of either copper or fiber optic cables that transmit data from one server to another, Hamza explained. The numerous cables are subject to wear and tear and also block airflow — thus requiring more cooling in the building.

“Cables result in high energy consumption and need a lot of management,” Hamza said.

Hamza’s team designed a simulator to explore different layouts for data center setup, along with different methods to move data around faster and more efficiently. They are experimenting with the use of laser beams — or optical wireless communication — to transmit data without the use of cables.

“Laser beams have the high-capacity feature of fiber optics, with the flexibility of wireless technology,” Hamza said.

However, the laser beams require “line of sight” communication, presenting a challenge with the traditional design of servers set up in rows. Hamza’s team is experimenting with a cellular design — geometric shapes facing one another in a configuration that resembles a beehive — to allow servers to transfer data from one point to another.

Ultimately, the team’s simulation tool will be made available to researchers across the country, Hamza said. “The tool can help us compare the performance of proposed designs, resulting in higher speed, more flexibility and more efficiency,” he said.
