Red Hat Storage Server 3 is an open software-defined storage solution for scale-out file storage that is designed for data-intensive enterprise workloads including big data, operational analytics and enterprise file sharing and collaboration. It is based on the open source GlusterFS 3.6 file system and Red Hat Enterprise Linux 6. Capabilities include support for up to 60 drives per server and 128 servers per cluster, providing a usable capacity of up to 19 petabytes per cluster; volume snapshots for point-in-time copy of critical data, and comprehensive monitoring of the storage cluster using open, industry standard frameworks, such as Nagios and SNMP; and integration with emerging big data analytics environments with support for a Hadoop File System Plug-In that enables running ApacheTM Hadoop workloads on the storage server, as well as tight integration with Apache Ambari for management and monitoring of Hadoop and underlying storage.
