Abstract
In the present paper we explore storage manage-
ment issues in proxy servers for distributed file sys-
tems. We organize the requested data at the disks of
the proxy server using locality-aware approaches. Ad-
ditionally, we introduce improvements in the map-
ping mechanism from remote to local data and con-
sider cost-aware replacement methods. In a prototype
implementation that we developed, we experimentally
compare alternative distributed file systems as com-
ponents of the proxy servers. Through extensive mea-
surements, we demonstrate throughput improvements
at the proxy server up to 80% in comparison to the
