      Deduplication is a storage saving technique that is highly successful in enterprise backup environments. On a file system, a single data block might be stored multiple times across different files, for example, multiple ...
    • Ad hoc file systems for high-performance computing 

      Brinkmann, Andre; Mohror, Kathryn; Yu, Weikuan; Carns, Philip; Cortés, Toni; Klasky, Scott A.; Miranda Bueno, Alberto; Pfreundt, Franz-Josef; Ross, Robert B.; Vef, Marc-André (2020-01-17)
      Article
      Restricted access - publisher's policy
      Storage backends of parallel compute clusters are still based mostly on magnetic disks, while newer and faster storage technologies such as flash-based SSDs or non-volatile random access memory (NVRAM) are deployed within ...
    • Direct lookup and hash-based metadata placement for local file systems 

      Lensing, Paul Hermann; Cortés, Toni; Brinkmann, Andre (Association for Computing Machinery (ACM), 2013)
      Conference report
      Restricted access - publisher's policy
      New challenges to file systems' metadata performance are imposed by the continuously growing number of files existing in file systems. The total amount of metadata can become too big to be cached, potentially leading to ...
    • File system scalability with highly decentralized metadata on independent storage devices 

      Lensing, Paul Hermann; Cortés, Toni; Hughes, Jim; Brinkmann, Andre (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Conference report
      Restricted access - publisher's policy
      This paper discusses using hard drives that integrate a key-value interface and network access in the actual drive hardware (Kinetic storage platform) to supply file system functionality in a large scale environment. Taking ...
    • Fusing storage and computing for the domain of business intelligence and analytics: research opportunities 

      Queralt Calafat, Anna; Marti Fraiz, Jonathan; Baars, Henning; Brinkmann, Andre; Cortés, Toni (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Conference report
      Restricted access - publisher's policy
      With the growing importance of external and shared data, the set of requirements for Business Intelligence and Analytics (BIA) is shifting. Current solutions still come with shortcomings, esp. In multi-stakeholder environments ...
    • GekkoFS: A temporary burst buffer file system for HPC applications 

      Vef, Marc-André; Moti, Nafiseh; Süb, Tim; Tacke, Markus; Tocci, Tommaso; Nou, Ramon; Miranda Bueno, Alberto; Cortés, Toni; Brinkmann, Andre (2020-01-17)
      Article
      Restricted access - publisher's policy
      Many scientific fields increasingly use high-performance computing (HPC) to process and analyze massive amounts of experimental data while storage systems in today’s HPC environments have to cope with new access patterns. ...
    • GekkoFS: A temporary distributed file system for HPC applications 

      Vef, Marc-André; Moti, Nafiseh; Süb, Tim; Tocci, Tommaso; Nou Castell, Ramon; Miranda, Alberto; Cortés, Toni; Brinkmann, Andre (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Open Access
      We present GekkoFS, a temporary, highly-scalable burst buffer file system which has been specifically optimized for new access patterns of data-intensive High-Performance Computing (HPC) applications. The file system ...
