The goal of VISION Cloud, a European Commission funded project, is to design a new scalable and flexible storage cloud architecture able to provide data-intensive storage cloud services.The proposed environment employs a distributed file system on top of a set of storage rich nodes composing a cluster.Several clusters constitute a data center, while multiple geographically distributed data centers form a single storage cloud.In this paper, we focus on a single VISION Cloud storage cluster, providing a stochastic reward net model for an investigation of its availability.The proposed model is a first attempt at obtaining a quantification of the availability level of the cloud storage provided by the VISION Cloud architecture.
