Constructing on important technological innovation innovations cultivated in excess of many years, Western Electronic is sampling its new market-leading 22TB and 26TB UltraSMR HDDs to find hyperscale cloud consumers, even further growing its areal density leadership and delivering consumer benefit by driving TCO lower.
Western Digital’s HDD engineering portfolio and areal density management puts it at the centre of storage innovation.
Leveraging its unique OptiNAND™ know-how, strength-assisted PMR (ePMR), triple-stage actuator (TSA), HelioSeal® and now UltraSMR technologies, Western Electronic is on a apparent path to offering 30+ TB with ePMR.
“As a longstanding spouse of the industry’s foremost cloud providers, we fully grasp their special prerequisites in developing up coming-technology cloud infrastructure and invested in quite a few HDD improvements we developed along with our areal density technological innovation,” stated Ashley Gorakhpurwalla, EVP and GM, HDD Small business Device, Western Electronic.
“Our intent with getting this progress technique was not only to deal with the ability needs of the world’s biggest cloud titans but to deliver on a roadmap that would also help the evolving economics of their data centers for many years to appear. With ePMR, OptiNAND and now UltraSMR as the basis of Western Digital’s HDD roadmap, our cloud clients can continue rapidly scaling their business by getting edge of our innovations to reduce their storage TCO.”
OptiNAND, UltraSMR and ePMR Drive Cloud TCO Lower
The new ePMR drives leverage Western Digital’s OptiNAND technology to unlock unprecedented levels of potential, efficiency and information resiliency.
The 22TB CMR HDD incorporates OptiNAND to provide areal-density management on a mature 2.2TB/platter HelioSeal system with 10 disks.
Combining OptiNAND with proprietary firmware that leverages HDD program-degree components breakthroughs, Western Digital’s new UltraSMR engineering introduces huge block encoding along with an highly developed mistake correction algorithm that boosts tracks-per-inch (TPI) to enable higher ability.
The consequence is Western Digital’s new 26TB Ultrastar® DC HC670 UltraSMR HDD that delivers 2.6TB per platter, providing 18% extra ability for cloud consumers optimizing their stacks to just take gain of the benefits of SMR.
With cloud service providers significantly including SMR to their datacenter roadmaps, the 26TB potential serves as a tipping stage to speed up adoption.
Uniquely able with OptiNAND, the HDDs also include the ArmorCache™ create cache details basic safety element, which presents buyers the functionality of compose cache allow (WCE) mixed with the info protection of publish cache disable (WCD) for included info safety or resiliency in scenario of an crisis electricity off (EPO).
For the initial time in HDD history, this Create Cache Details Protection feature provides users both of those efficiency and facts safety, no matter which manner is chosen.
Western Electronic OptiNAND presents the drives a considerable overall performance enhance also in WCD mode, which is biggest in random writes with bigger block transfers.
At popular HDD application transfer lengths of 256KB or increased, IOPS and throughput increase by additional than 40% relative to a non-OptiNAND drives, with a peak improvement of about 80% at 1MB transfer duration. See the tech quick in this article for extra aspects.
