Les vies et les carrières d’André Chamson et d’André Malraux se ressemblent par de multiples aspects. Contemporains, ils se connaissaient bien, menaient souvent les mêmes combats, souffraient des mêmes préoccupations, Mais c’est surtout par rapport à l’esprit qui les animait, en tant que grandes personnalités marquantes du XXe siècle, que d’intéressants parallèles peuvent être établis entre eux, que nous pouvons avec profit examiner les valeurs universelles et spirituelles qu’ils promouvaient, valeurs emblématiques pour tant de penseurs, d’acteurs, et d’écrivains de ce siècle. Ainsi pourrions-nous par ailleurs interroger et même évaluer la solidité, la résistance et le potentiel de telles valeurs pour le siècle à venir.

We propose simple models to predict the performance degradation of disk requests due to storage device contention in consolidated virtualized environments. Model parameters can be deduced from measurements obtained inside Virtual Machines (VMs) from a system where a single VM accesses a remote storage server. The parameterized model can then be used to predict the effect of storage contention when multiple VMs are consolidated on the same server. We first propose a trace-driven approach that evaluates a queueing network with fair share scheduling using simulation. The model parameters consider Virtual Machine Monitor level disk access optimizations and rely on a calibration technique. We further present a measurement-based approach that allows a distinct characterization of read/write performance attributes. In particular, we define simple linear prediction models for I/O request mean response times, throughputs and read/write mixes, as well as a simulation model for predicting response time distributions. We found our models to be effective in predicting such quantities across a range of synthetic and emulated application workloads.
