  Abstract: Department of Information and Communications Engineering, Universitat Auto`noma de Barcelona{Bernat.Gaston | Jaume.Pujol | Merce.Villanueva}@uab.catAbstractIn a distributed storage environment, where the data is placed in nodes connected through a network, it is likelythat one of these nodes fails. It is known that the use of erasure coding improves the fault tolerance and minimizesthe redundancy added in distributed storage environments. The use of regenerating codes not only make the most ofthe erasure coding improvements, but also minimizes the amount of data needed to regenerate a failed node.In this paper, a new family of regenerating codes based on quasi-cyclic codes is presented. Quasi-cyclic ﬂexibleminimum storage regenerating (QCFMSR) codes are constructed and their existence is proved. Quasi-cyclic ﬂexibleregenerating codes with minimum bandwidth constructed from a base QCFMSR code are also provided. These codesnot only achieve optimal MBR parameters in terms of stored data and repair bandwidth, but also for an speciﬁcchoice of the parameters involved, they can be decreased under the optimal MBR point.Quasi-cyclic ﬂexible regenerating codes are very interesting because of their simplicity and low complexity. Theyallow exact repair-by-transfer in the minimum bandwidth case and an exact pseudo repair-by-transfer in the MSRcase, where operations are needed only when a new node enters into the system replacing a lost one.
