![]() The SL4500 servers hold up to 60 drives each. "ĭaley is currently testing more than a dozen of HGST's He6 6TB drives in HP's SL4500 servers, and expects hundreds of the drives to be in the servers by the end of the month. "We are seeing about 2-watt lower power on random workloads compared to today's 4TB. As we deploy solutions that are tens and hundreds of petabytes, anything you can do to increase density is a boon," said Jimmy Daley, director of Smart Storage at Hewlett-Packard. HGST said it's been working with key computer manufacturers, cloud and research groups, including HP, Huawei Unified Storage, Green Revolution Cooling, Code42, CERN as well as some of the world's largest social media and search companies, to qualify the drive. The high storage density and lower power usage of the Ultrastar He6 hard drives allow us to continue with that goal, and create a great customer experience," Fullagar said. "As part of our efforts to optimize the delivery ecosystem for Netflix and our Internet Service Provider partners, we strive to build better and better streaming appliances. Netflix serves up billions of hours of streaming video per quarter to over 40 million subscribers requires a constant effort to optimize server infrastructure, according to David Fullagar, director of Content Delivery Architecture at Netflix. Netflix, which uses HGST high-capacity hard drives in its data centers, said the increase in capacity and lower power-usage in the Ultrastar He6 hard drives will go a long ways toward optimizing their streaming video server infrastructure. Sealing air out of the drive also keeps humidity and other contaminates from getting in. The helium-drives run at four to five degrees cooler than today's 7200rpm drives, HGST stated. While the Ultrastar He6's 50% boost in capacity is impressive, what's most notable is the power reduction, Zhang said, because the high-capacity drives will be used in large data centers and cloud infrastructures.Īt one-seventh the density of air, helium produces less drag on the moving components of a drive - the spinning disk platters and actuator arms - which translates into less friction and lower operating temperatures. "I'd say helium is one of the major breakthroughs in the hard drive industry because you can only increase the platter areal density so much with today's technology," said Fang Zhang, an analyst at market researcher IHS. While HGST would not release specific pricing for the drives, as they will be sold to server and storage array manufactures, the company did say the drives will "command a premium" not just based on capacity, the lower total cost of ownership that the helium technology offers.
