pdf.png D2.2 IOStack Architecture Specifications and Benchmarking Framework 1.0 HOT

Download

This document provides a comprehensive description of the architecture of IOStack. In particular, this document describes each of the building blocks that constitute the Software-Defined Storage (SDS) toolkit as well as their interactions within the architecture. Moreover, we show experimental results of IOStack that demonstrate the feasibility of the architectural design and the correctness and potential of the toolkit itself.

pdf.png D2.3 Public release of the IOStack Toolkit 1.2 HOT

Download

This document describes the progress of the IOStack toolkit until M24 and its software building blocks: Zoe, Konnector and Crystal. The second part of the document is focused on Crystal, the first SDS architecture for object storage, and describes how Crystal implements the filter abstraction to accommodate new storage optimizations that can be easily orchestrated via high-level policies. This deliverable also provides a first description and evaluation of results obtained from validation in use cases using different workloads.
