Stable release and specifications of the SDS framework for analytics Description and specification of the the stable release of the system including all APIs and the software components that implement these APIs: the admin toolset, collector, provisioner, and the storage offload. System object model design This deliverable describes the object model of the compute and storage system. This system object model is the dataset that the SDS framework helper functions will operate on. All provisioning requests from the SDS framework will use the system object model. The system object model is implemented as a database which requires setup. The database is created in two steps, step 1 using the Admin toolset which allows a high level abstraction of system containers with associated policies to be created, step 2 is to map physical assets to the logical groups and define the properties of those assets. The provisioning tools then use this database to make provisioning requests. This deliverable also contains the complete set of APIs to access the SDS system object model from other components developed in other workpackages. Data Management Plan First version of the data management plan describing project management strategies. The different experiments, workloads, benchmarks, and results will be delivered as Open Research Data for the community. This deliverable will evolve during the lifetime of the project in order to present the status of the project’s reflections on data management. SDS Toolkit initial prototype Initial implementation of several components that implements the API specification. The system object model contains run time data used by the provisioning tools to decide how to optimally make a provisioning request. Specifically, the collector is responsible for collector run time data which is used in the provisioning process. The collector is also responsible for discovery and building the topology of the participating nodes and resources. This deliverable also receives the SDS Rest API provisioning request, scans the system object model and uses policies, heuristics, topology and run time data to make an optimal decision as to which resource should be used to satisfy the provisioning request. The system design will allow for the possibility of different heuristics (ex. Optimal speed, minimal cost etc). This deliverable also implements the API functions to run a compute operation on the storage node allowing the analytics process to be implemented with both compute based and storage based compute operations. First Period Management Report First Period Management report including completion of deliverables and tasks, as well as resources and efforts spent by partners and description of activities in this period. Prototype and initial evaluation This deliverable presents an implementation of the storlets for analytics framework and evaluates initial performance. Also research results and/or implementations are presented for the data reduction and performance optimization tasks. System Deployment Strategies This deliverable presents the system model, optimization objectives and the corresponding algorithms to find suitable deployment strategies that satisfy the constraints imposed by the model. Such deployment strategies and algorithms determine, to a large extent, the system deployment tools developed in the project.

Consolidated System Monitoring and Deployment Tools This deliverable presents the integrated system architecture and consolidated results on the performance achieved by the joint operation of monitoring and deployment tools. System Monitoring Design and Preliminary Evaluation This deliverable describes the architecture of the monitoring tools required to define system models, which allow to reason about deployment strategies, and presents preliminary results on the system performance when DISC frameworks are deployed according to naive strategies.
