Red Hat today rolled out the beta version of Red Hat Storage Software 2.0, used to build scale-out network-attached storage (NAS) for unstructured data. The upgraded version includes new features such as the ability to access both file and object-based data from a single storage pool and support for Hadoop in “big data” environments.
Version 2 is the first major upgrade for Red Hat since it acquired startup Gluster last year. Current versions of Red Hat Storage on the market are re-branded versions of the GlusterFS product with tweaks to better support the Red Hat Enterprise Linux (RHEL) operating system.
Red Hat Storage Software 2.0 makes it easier to manage unstructured CIFS, NFS and GlusterFS mount points. The unified file and object feature allows for users to save data as an object and retrieve it as a file, or save data as an object and retrieve it as a file.
“A typical use case would be a customer can choose to save something as an object or file. So you can upload a photo as a file but in the portal software it is converted into an object,” said Sarangan Rangachari, general manager for storage at Red Hat.
The 2.0 version supports Hadoop MapReduce, which is a programming language and software framework for writing applications that rapidly process large amounts of data in parallel on large clusters of compute modes. “What we provide in this release is the underlying file system in MapReduce-based applications that use the Hadoop Distributed File System (HDFS),” Rangachari said.
The Red Hat Storage Software provides a global namespace capability that aggregates disk and memory resources into a unified storage volume. The software runs on commodity servers and uses a combination of open source Gluster software, which Red Hat acquired in October 2011, and Red Hat Linux 6. In February, Red Hat also introduced the Red Hat Virtual Storage Appliance for scale-out NAS delivered as a virtual appliance. This allows customers to deploy virtual storage servers the same way virtual machines are deployed in the cloud.
The Red Hat appliance allows the ability to aggregate both Elastic Block Storage (EBS) and Elastic Compute Cloud (EC2) instances in Amazon Web Service environments.
