The goal of distributed storage systems is to store data in a network, which consists of several nodes. Two main challenges in the development of such systems are the reliability of the data availability and the efficiency of the data storage. Further, the required amount of traffic in the network when repairing node failures or updating stored data, should be minimized.Modeling the stored information per node as symbols (over a finite field) allows the application of algebraic error-correcting codes. In this application, we identify several future research directions and challenges of distributed storage systems and connect some scenarios with new decoding algorithms of Reed--Solomon codes. This code family suits well for distributed storage systems due to their maximum distance separable property.
