Mr. Dennis Hahn, a senior analyst at IHS Markit, covers data center storage technologies.

Dennis Hahn, MBA is a senior analyst in IHS Markit’s Cloud and Data Center Research Practice, where he is responsible for covering data center storage technologies, including SAN, NAS, DAS, cloud storage, NVMeoF, and Software-Defined Storage (SDS). Dennis joined IHS Markit in April 2018 and has more than 25 years of broad storage industry technology experience covering storage systems design, product and project management, corporate and product strategy, and storage innovations development and market insight.

Before joining IHS Markit, Dennis led efforts at NetApp in product strategy, innovation, advanced development, and market differentiation for the E-Series product line, which went on to become a $1B business. Enhancements under his team leadership include the NetApp Data Fabric, Array Integrated Host Flash Caching, Kubernetes support, and an innovative AWS-resident Cloud Data Recovery Portal service.  

Prior to NetApp, Dennis held a range of storage technology management and development positions at companies such as Symbios Logic, Engenio and LSI. Throughout his industry tenure, he developed a deep understanding of storage technologies and worked closely with executive teams to influence feature requirements and product direction.  During this period, he created winning products such as the MetaStore SAN product, which grew to $60M in annual revenue in 4 years.

In addition, Dennis also mentored students and guided their projects in conjunction with the Center for Research in Intelligent Storage (CRIS) at the University of Minnesota.  Publications include Architecture: File System I/O Access Hints for Performance Enhancement at Block Layer, OneStore: Integrating Local and Cloud Storage with Access Hints, and ChewAnalyzer: Chunk Level Data Management across Differentiated Storage Pools.

Dennis earned his Bachelor of Science in Mechanical Engineering degree at University of Wisconsin-Platteville and his MBA degree from Wichita State University, both in the US. He holds patents in storage systems design, data caching and hybrid cloud data migration; and is certified in Agile development practices (PMI-ACP, est. ‘17) and cloud solutions architectures (AWS -SAA, est. ‘18).

SNIA SDC 2018: In search of a new storage architecture

The Storage Networking Industry Association (SNIA) Storage Developers Conference (SDC) 2018 was held in Santa Clara, California, from 24 to 27 September 2018. SDC is a technical conference and bills itself as a conference “created by developers for developers.” Its goal is to inform the storage community about the latest technologies and provide a platform for storage industry collaboration. I overheard someone at the conference state “only about 50% of the things discussed at the conference will make it into real products,” and the other ideas will just be discussed and forgotten. As an industry association conference, there was a strong emphasis on education and collaboration among those working on storage projects or technical working groups (TWGs). The industry needs strong communities like these that provide vendor-neutral content and education, separate from commercial conferences where companies heavily promote their products.

Flash Memory Summit 2018: Realizing the full benefits of flash

Last month, I attended the Flash Memory Summit (FMS) in Santa Clara, California, a conference that focuses on the various flash technologies and their adoption in the data center. FMS 2018 reported over 6,000 registrations, making it one of the largest independent storage conferences. There were over 16 keynotes and many more educational sessions, as well as an exhibition hall with companies showing off their latest flash chips, devices, interconnects, and even complete storage arrays. Verizon, Toshiba, WDC/DCS, Micron, SK Hynix, Yangtze Memory, Intel, Solarflare, Xilinx, Marvell, ScaleFlux, Microsemi, Shannon Systems, NGD Systems, Smart IOPS, and Huawei Technologies provided keynotes. If you want a deep education in some of the latest flash technologies or even on how to develop your own flash controller, this is the conference for you—but it also has high-level sessions mixed into the educational offerings.
