Abstract
In this paper we present two alternative ways of imple-
menting a meta-data management subsystem for the N3FS
distributed file system using Chord. In order to obtain high
availability in presence of node failures and network losses,
we develop solutions based either on replication or on re-
dundancy. In order to assess the relative merits of these
alternatives in terms of performance and availability, we
performed an extensive simulation analysis. Our prelimi-
nary results indicate that, while there is not a clear winner
in terms of absolute performance, the redundancy-basedso-
lution is characterized by an availability higher than the
replication-based counterpart, especially in scenarios when
node failures or network losses increase.
