“…A storage QoS model -RSMM (Resource Storage Management Model) targeted at QoS provisioning for data storage service based on HSM (Hierarchical Storage Management) systems is presented in [20]. Replication is also used in the Onedata system for managing consistency for global scalable data access [53]. The further problems, like hierarchical QoS for packet scheduling for different workloads in a hypervisor or dealing with multi-tiered storage systems can be found [4,8].…”

There is high demand for storage related services supporting scientists in their research activities. Those services are expected to provide not only capacity but also features allowing for more flexible and cost efficient usage. Such features include easy multiplatform data access, long term data retention, support for performance and cost differentiating of SLA restricted data access. The paper presents a policy-based SLA storage management model for distributed data storage services. The model allows for automated management of distributed data aimed at QoS provisioning with no strict resource reservation. The problem of providing users with the required QoS requirements is complex, and therefore the model implements heuristic approach for solving it. The corresponding system architecture, metrics and methods for SLA focused storage management are developed and tested in a real, nationwide environment.

Open-data research is an important factor accelerating the production and analysis of scientific results as well as worldwide collaboration; still, very little data is being shared at scale. The aim of this article is to analyze existing data-access solutions along with their usage limitations. After analyzing the existing solutions and data-access stakeholder needs, the authors propose their own vision of a data-access model.
