Fault tolerance for large scale storage systems

Abstract

With exponential increase in the digital information the amount of data that enterprises should manage is very tedious and storage systems are frequently scaled to meet the industry demand and service level agreements. As the storage systems are scaled, validating the storage systems installation becomes very desirable as this help in notifying the reliability, availability, performance issues, analyzing the downtime, taking backup, snapshots, mirroring the image, making decisions to avoid single point of failure ...etc. This task of validating the storage systems installation becomes very tedious as the number of wiring configurations increases exponentially when they are scaled and process of validation needs automation as it can lead to misconfigurations even at maximum attention if done manually. In this paper we present a solution to ensuring a high degree of availability and reliability in large scale storage systems. © 2013 Springer.
