Un Driver de Disco Virtual Tolerante a Fallos

Abstract

One of the main service models of Cloud Computing is Infrastructure as a Service (IaaS). It offers computational and storage resources by using virtualization technologies. The most widespread technology is known as Hardware virtualization, but new ones are emerging such as Operating System level virtualization and Containers.
This article refers to a virtual disk driver to be used by a new technology of distributed virtualization (DRVS). In a DRVS virtual machine the computational, storage and network resources are distributed in different nodes of a cluster. DRVS not operate on real hardware but on virtual devices using the services of an underlying Operating System. While there are several storage virtualization technologies, DRVS requires location transparency and replication/migration capabilities to improve service availability.
