Our paper titled “NVM in Data Storage: A Post-Optane Future” has been accepted by ACM Transactions on Storage for their Special Issue on Computational Storage
Abstract The dynamic evolution of non-volatile memory (NVM) technologies from Read-Only Memory (ROM) to flash memory, and recent innovations in Magnetoresistive RAM (MRAM), Phase Change Memory (PCM), and Resistive RAM (ReRAM) signify a pivotal shift in data storage capabilities and applications. This progression, marked by enhancements in performance and density, fills the gap between Dynamic RAM (DRAM) and flash storage, meeting the demands of data-rich domains such as high-performance computing and databases.
Our paper titled “A Design Proposal for a Unified B-epsilon-Tree: Embracing NVM in Memory Hierarchies” has been accepted at the 35th GI-Workshop on Foundations of Databases, May 22-24, 2024, Herdecke, Germany)
Abstract Non-volatile memory (NVM) represents a new class in the traditional storage hierarchy. The technologies in this class share characteristics of both primary and secondary storage; they provide latency that approaches that of DRAM, albeit moderately higher1, yet significantly lower than that of secondary storage devices, are addressable from cache lines, and, most importantly, offer persistence.
Our paper titled “Embracing NVM: Optimizing B-epsilon-Tree Structures and Data Compression in Storage Engines” has been accepted at the 3rd Workshop on Novel Data Management Ideas on Heterogeneous Hardware Architectures (NoDMC), co-located to BTW 2025 (Bamberg, Germany, March 3 - 7, 2025))
Abstract Non-volatile memory (NVM) introduces a new class within the traditional storage hierarchy, combining attributes of both primary and secondary storage. NVM technologies offer latency approaching that of DRAM, though slightly higher, and significantly lower than traditional block storage devices.
Our manuscript entitled “NVM in Data Storage: A Post-Optane Future” which we had submitted as an abstract to the Transactions on Storage, Special Issue titled “Past, Present, and Future of Storage” has been reviewed.
The reviewer(s) have recommended inviting us to submit a full paper, which will show up as a request for major revision of our abstract.
Our paper titled “Assessing Non-volatile Memory in Modern Heterogeneous Storage Landscape using aWrite-optimized Storage Stack” has been accepted at the 34th workshop on basics of database systems (Grundlage von Datenbanken)
Abstract Non-Volatile memory (NVM), or persistent memory, is a promising and emerging storage technology that has not only disrupted the typical long-established memory hierarchy but also invalidated the proclaimed programming paradigm used in traditional database management systems and file systems. It bridges the gap between primary and secondary storage and, hence, shares the characteristics of both categories.
Our paper titled “Intelligent Data Migration Policies in a Write-Optimized Copy-on-Write Tiered Storage Stack” has been accepted at CHEOPS ‘23: Proceedings of the 3rd Workshop on Challenges and Opportunities of Efficient and Performant Storage Systems
Abstract Modern storage stacks increasingly aim to intellegently optimize data accesses to improve latency, throughput, and energy consumption. Additionally, new storage setups become more heterogeneous, due to the introduction of new storage media, like NVM, and ever-increasing requirements regarding storage capacity and performance.
