Driving Down Data Center TCO: The Value of HelioSeal Technology
With the amount of new data being created and replicated doubling every two years, data center architects have a lot to consider when planning for future growth. Capacity growth is only one piece of the equation. The additional power, cooling and floor space required to operate that extra storage is another, and can add up. Leveraging the inherent benefits of Helium, HGST’s HelioSeal technology delivers today’s lowest TCO for enterprise and cloud data centers through:
- Greater power efficiency – Disks spin more easily in a helium-filled environment, resulting in 23% lower operating power. The 8TB helium drives consume just 5.1 watts during idle operation, a 44% reduction in watts-per-TB compared to conventional 6TB air-based HDDs, creating greener data centers with reduced energy costs and carbon footprint.
- Leading storage density – Helium is essential to maintaining the required reliability for future generation drives beyond 8TB. Industry-leading 8TB capacity in a 3.5-inch HDD footprint, which are plug-and-play in virtually any data center environment, delivers 33% more storage capacity for mainstream applications than competitive 6TB offerings.
- Lower cooling requirements – HGST Helium-filled drives typically run 4˚–5˚C cooler, which lowers power and cooling costs and leads to better field reliability, allowing HGST to increase its MTBF specification for the He6 and He8 drives.
- Better weight-per-TB – Up to 38% lower weight-per-TB for improved environmental conditions in high-density deployments and allows for more storage capacity where building codes enforce floor loading limits.
- Environmental robustness – Use them virtually anywhere, including ambient air, free cooling data centers. Many air-filled drives use a breather filter leading to reliability problems when used in environments with high levels of carbon or dust, or in high altitudes. This problem does not exist with HelioSeal drives as they’re hermetically sealed.
- Value $/TB – Higher volume production for its second-generation 8TB HelioSeal HDD leads to lower cost to the market.
HGST is shipping its 6TB Ultrastar He6 and 8TB Ultrastar He8 helium-filled drives in volume today. HGST’s 10TB Helium HDDs with SMR are sampling with select customers. For more information, please visit:http://www.hgst.com.
Karyn DiGiorgio will guide center in spreading health care delivery innovations systemwide.
Karyn DiGiorgio, M.S.N., R.N., has been appointed interim director of the UC Center for Health Quality and Innovation (CHQI).
The center, based at the UC Office of the President, is a systemwide effort launched in 2010 to support innovative grants and spread best practices that aim to improve quality, increase efficiencies and reduce costs at UC medical centers.
DiGiorgio joined UCOP in September as the associate director of CHQI, after working for the Gordon and Betty Moore Foundation, where she was a program officer in the Betty Irene Moore Nursing Initiative.
“The UC Center for Health Quality and Innovation will be in good hands under Karyn’s leadership,” said the center’s outgoing executive director, Terry Leach, R.N., Esq., who will continue working part time with the center until retiring from UC in July.
“I look forward to working with UC campuses and medical centers to help spread innovations that improve the delivery of health care throughout UC Health,” DiGiorgio said. “I very much appreciate having Terry’s assistance during this transition.”
At the Moore Foundation, DiGiorgio developed and managed multiple systemwide health care grants in the Bay Area and greater Sacramento regions — many of which resulted in significant reductions in patient morbidity and mortality and led to improvements in patient care. Previously, she worked as the R.N. discharge coordinator and a staff/charge nurse in the Emergency Department at UCSF Medical Center. She is a graduate of Georgetown University and holds an M.S.N. in health policy from UC San Francisco and an M.S. from Drexel University in Philadelphia.
The Center for Health Quality and Innovation is governed by a board composed of the six UC medical school deans, five UC medical center CEOs and chaired by the UC Health senior vice president. The center will host its third annual spring colloquium May 2 in Oakland.
Filling the cavity of an HDD with helium nearly eliminates the wind turbulence that disturbs the heads. This gives HDD manufacturers design freedom to add more disks and heads to an HDD to reach a higher capacity without adversely affecting the drive’s reliability.
A sealed helium-filled drive cavity also significantly reduces the friction that occurs while disks are spinning inside the drive. Less power will be needed to operate a sealed helium-filled drive, and in the future, more disks could be added to the drive without adversely impacting power consumption.
HGST’s HelioSeal platform may be considered by some as unconventional. However, some HDD manufacturers already fill the drive cavity with helium temporarily during the HDD manufacturing process. Filling the drive cavity with helium temporarily is unexceptional. On the other hand, preventing helium from escaping from a disk drive over a prolonged period of time, over its entire useful life, is extraordinary.
