Storage Insights in the Age of AI

Ulrich Hansen 氏

The 'New Era of AI' has begun. It is becoming more apparent that 'this next generation of AI will reshape every software category and every business' (Satya Nadella), and as a result investments in AI solutions and infrastructure are accelerating dramatically. Microsoft is a global leader in AI, and Microsoft Azure Cloud provides leading infrastructure and application services for Cloud-based AI solutions. In Azure, we are actively revisiting and investing in all elements of AI solution infrastructure, including Storage. Building on Azure's learnings from the last several years of integrating Storage into AI-optimized systems and solutions, this talk will summarize the current state of Storage in Cloud-scale AI solutions and explore future trends for Storage in AI. The talk will include the role of Storage in various types of AI solutions across training and inference use cases and describe the role of both high-performance Storage co-located with the compute infrastructure as well as cost-effective remote Storage. Finally, Storage device implications for both devices based on magnetic and solid-state storage media will be addressed.


The HAMR Journey

Vice President Research
Edward Charles Gage 氏   

Today's heat assisted magnetic recording products trace their origins back to the hybrid optical magnetic recording developments in the mid 1990's. The HAMR technology development featured a number of key inventions including a whole new media recording layer based on ordered FePt and a plasmonic near field transducer. The ability to record on very high anisotropy granular media with a recording footprint defined by a thermal spot in the media, has allowed us to extend capacities to 3 TB/disk and beyond in a 3.5" form factor. Demonstrations at 5 TB/disk will be shown along with ideas to extend the technology to 10 TB/disk.


Next Generation HAMR head designs

Moris Dovek 氏 

HAMR is generally accepted by the HDD industry as the technology of choice for extending areal density for several generations of future products. Transducer (NFT) and write head designs have aimed to improve thermal gradients and the alignment between magnetics and optics. While kbpi growth by improving thermal gradient has rendered diminishing returns, the path to areal density growth has been clearer with increased ktpi. The thermal gradient boost achieved by scaling NFT dimensions and other geometric improvements, especially when it also appears in the cross track thermal gradient, has translated to increased ktpi. This increased track density can be realized best if in combination with a narrow reader that follows the track pitch while maintaining head SNR. Effects of head field enhancements on areal density will also be addressed as well as outlining other areal density dependencies of the head structure.

The Revolution of Tape

<資料> IBM Corporation
Director, TAPE & TS7700 Development
Chris Telford Teale 氏

Since 1952, the evolution of tape storage has been well documented and is perceived as relatively predictable well into the future. But what if tape is actually on the verge of a revolution, thanks to AI and a popular enabler, S3. If so, it will take more than AI and S3 to bring on the Tape Revolution. Advancement in tape automation, originally designed for hyperscalers, is proving attractive to traditional tape lovers and ex-lovers alike. Learn how IBM is removing customer pain points while improving data rate and density in order to expand and re-launch tape into data centers around the world.


Data Storage Market Picks up Momentum

Mark Geenen 氏

Long-anticipated improvements starting with hyperscale growth for nearline HDDs. After several quarters of of confusing and conflicting demand for data storage, the industry has reached a low point and has now bounced off that. Of course, demand patterns are unusual and non-linear, but the cloud is leading the storage industry back to growth and profitability. But how long will it last?


Understanding the Present and Potential of Area Density Capability for HAMR

<資料> Carnegie Mellon University
Data Storage Systems Center
ABB Professor of Engineering
Jimmy Zhu 氏

In conventional perpendicular magnetic recording, magnetic grains of medium only have two saturated magnetization states along its magnetic easy axis. The resulting binary noise at recorded transitions yields the medium SNR to linearly depending on the number of grains across the data track width. In HAMR, this understanding is altered. The FePt-L10 grains can have domains trapped inside during a recording process, yields grains at transition centers to have zero or close-to-zero magnetic moments. The fractionally magnetized grains significantly reduce the binary noise, effectively enhancing the number of the grains across a recording track. This mechanism is responsible for the relatively high track density achieved today in HAMR.
Recent thermal erasure noise experimental measurements have confirmed the predicted existence of zero moment grains in current FePt-L10 HAMR media as well as the corresponding reduction of medium noise power. The zero moment state of the grains potentially gives rise to one additional state to the other two saturated state. This give rise to a possibility of 3-level recording in which the area recording density can be increased by 50% without any reduction of either track width or bit length. The talk will focus on the challenges in recording processes and potential schemes needed to enable the 3-level recording.

Hard Disk Drive Innovations in The Era of Cloud Storage

<資料> Western Digital
Carl Che 氏

In the last two decades, cloud centers have revolutionized our data storage methods, significantly accelerating data growth and ushering us into the zettabyte era. This revolution has also spurred new opportunities for HDD innovations to address the vast demand for cloud data storage.
With a focus on adapting to this cloud transformation, our industry has advanced innovative solutions specifically optimized to meet cloud storage needs. These include the development of Helium-filled drives, Ultra-Shingled Magnetic Recording (Ultra-SMR), and an advanced mechanical platform capable of scaling up to 1MTPI. These innovations are not merely incremental improvements; they represent significant shifts within the HDD industry, establishing new benchmarks in data storage capabilities.
As the pace of recording density increase is challenged by the thermal stability trilemma, these innovations have emerged as pivotal enablers in the lead-up to the transition to Heat-Assisted Magnetic Recording (HAMR) technology. They have been crucial for the industry to keep pace with the rapidly expanding storage requirements of the cloud.
With the introduction of these technologies and the onset of HAMR, our industry's technology roadmap has been significantly enhanced, positioning us to effectively accommodate the expected surge in cloud data volume, which is anticipated to be further accelerated by advancements in Artificial Intelligence.
