    Efficient Implementation of Data Objects in the OSD+-Based Fusion Parallel File System
    (Springer International Publishing AG, part of Springer Nature 2018, 2017-08-28) Piernas Cánovas, Juan; González Férez, Pilar; Ingeniería y Tecnología de Computadores
    OSD+s are enhanced object-based storage devices (OSDs) able to deal with both data and metadata operations via data and directory objects, respectively. So far, we have focused on designing and implementing efficient directory objects in OSD+s. This paper, however, presents our work on also supporting data objects, and describes how the coexistence of both kinds of objects in OSD+s is profited to efficiently implement data objects and to speed up some common file operations. We compare our OSD+-based Fusion Parallel File System (FPFS) with Lustre and OrangeFS. Results show that FPFS provides a performance up 37x to better than Lustre, and up 95x to better than OrangeFS, for metadata workloads. FPFS also provides 34% more bandwidth than OrangeFS for data workloads, and competes with Lustre for data writes. Results also show serious scalability problems in Lustre and OrangeFS.

    Leveraging OSD+ devices for implementing a high‐throughput parallel file system
    (John Wiley & Sons, Ltd, 2019-11-10) Piernas Cánovas, Juan; González Férez, Pilar; Ingeniería y Tecnología de Computadores
    OSD+s are enhanced object-based storage devices (OSDs) able to deal with both data and metadata operations via data and directory objects, respectively. So far, we have focused on designing and implementing efficient directory objects in OSD+s. This paper, however, presents our work on also supporting data objects, and describes how the coexistence of both kinds of objects in each OSD+ is profited to efficiently implement data objects and to speed up some common file operations. We compare our OSD+-based Fusion Parallel File System (FPFS) with Lustre and OrangeFS through different microbenchmarks and HPCS-IO scenarios. Results show that FPFS provides a throughput up to 37× better than Lustre, and up to 95× better than OrangeFS, for metadata workloads. FPFS also provides 34% more bandwidth than OrangeFS for data workloads, and competes with Lustre in data writes. Results also show serious scalability problems in Lustre and OrangeFS that limit their performance.
