The Hadoop distributed file System (HDFS) has a single metadata server that sets a hard limit on its maximun size. Ceph, a high-performace distributed file system under development since 2005 and now supported in Linux, bypasses the scaling limits of HDFS. We describe Ceph and its elements and provide instruction for intalling a demostration system that can be used with Hadoop.
