eHarmony Selects SeaMicro to Streamline Hadoop Capabilities

SeaMicro Low-Power Servers Dramatically Reduce eHarmony's TCO

SUNNYVALE, CA--(Marketwire - Jun 13, 2011) - eHarmony, the online service that uses relationship science to match singles seeking long-term relationships, has selected SeaMicro's SM10000™ servers to dramatically reduce total cost of ownership.

eHarmony selected SeaMicro -- the pioneer in low-power server technology -- after extensive testing with positive results. Previously, eHarmony used cloud services to run its Apache Hadoop application. After eHarmony brought the Hadoop cluster in-house by purchasing SeaMicro systems, they experienced a massive reduction in operational cost.

Millions of people use eHarmony's singles matching service, which matches people based on 29 Dimensions® of Compatibility, to find long-term relationships. The system is enormously successful, with an average of 542 eHarmony members marrying daily in the United States.

However, the complex datasets are very compute intensive. Each day, eHarmony would spend a few hours in the cloud running Apache Hadoop, culling the information provided by its millions of members and using its complex algorithms to find possible matches.

"We were paying huge amounts for a few hours of compute in the cloud," says Cormac Twomey, director of software engineering at eHarmony. "We worked closely with SeaMicro to bring the SM10000 servers in-house, and since then we have enjoyed a dramatic reduction in operating expense and have seen a substantial reduction in variability around job completion times. We now have an additional 20 hours of compute per-day at our disposal. Not only did SeaMicro deliver an exceptional product, but it has repeatedly demonstrated that it is an exceptional partner as well."

"Hadoop is an ideal application for SeaMicro," says Anil Rao, vice president of product management, SeaMicro. "We have been able to show Hadoop users how to improve their time-to-job completion while reducing their power consumption, space consumption and slashing operating expense. It is very exciting to be able to demonstrate such significant savings for an industry leader like eHarmony."

SeaMicro's SM10000 family is the world's most energy efficient server, using just one-quarter the power and one-quarter the space of traditional servers without the need for software changes. The systems combine SeaMicro's revolutionary server architecture with either 256 64-bit Intel® Atom™ N570 dual-core processors or 512 32-bit Intel® Atom™ Z530 processors. The result delivers an industry leading 512 1.66 GHz x86 cores in a 10 rack unit-tall (17.5 inches) system.
