    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 ...
  • 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

    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

    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 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 ...
