Cassandra
a distributed storage system for managing structured data that is designed to scale to a very large size across many commodity servers, with no single point of failure. Reliability at massive scale is a very big challenge. At this scale, small and large components fail continuously. Cassandra manages the persistent state in the face of these failures drives the reliability and scalability of the software systems relying on this service.

OCFS2
OCFS2 is a POSIX-compliant shared-disk cluster file system for Linux capable of providing both high performance and high availability. As it provides local file system semantics, it can be used with any application. Cluster-aware applications will be able to make use of parallel I/O for higher performance. Other applications, if not able to benefit from parallel I/O, will be able to make use of the file system to provide a fail-over setup to increase the availability of the application. Apart from being used with Oracle's Real Application Cluster database product, OCFS2 is currently in use to provide scalable web-servers and file-servers as well as fail-over mail-servers and for hosting virtual machine images.

Red Hat GFS (Global File System)
What if you could manage a cluster of servers, as if it were one server? Red Hat Global File System (GFS) helps you get there today, so that you can maximize the benefits of clustering and minimize the costs.

IBM GPFS (General Parallel File System)
The IBM General Parallel File System™ (GPFS™) is a high-performance scalable file management solution that provides fast, reliable access to a common set of file data from a single computer to hundreds of systems. GPFS integrates into your environment by bringing together mixed server and storage components to provide a common view to enterprise file data. GPFS provides online storage management, scalable access and integrated information lifecycle tools capable of managing petabytes of data and billions of files.

GPFS on Ubuntu
GPFS stands for the Global Parallel File System. It is a commercial product from IBM, and is available for purchase for use on AIX and Linux platforms. Linux packages and official support are currently only available for Red Hat and SuSE. If you choose to install GPFS on Ubuntu, it is important for you to understand that your install will not supported by IBM. But it may still be useful. GPFS provides for incredible scalability, good performance, and fault tolerance (Ie: machines can go down, and the filesystem is still accessible to others). For more information on GPFS, click here. We run Ubuntu as our standard Linux distribution, and so I set forth to find a way to make GPFS work on Ubuntu. These are the steps that I took, that hopefully will also allow you to produce a working GPFS cluster.

Lustre
Lustre is a scalable, secure, robust, highly-available cluster file system. It is designed, developed and maintained by Sun Microsystems, Inc. The central goal is the development of a next-generation cluster file system which can serve clusters with 10,000's of nodes, provide petabytes of storage, and move 100's of GB/sec with state-of-the-art security and management infrastructure. Lustre runs on many of the largest Linux clusters in the world, and is included by Sun's partners as a core component of their cluster offering (examples include HP StorageWorks SFS, and the Cray XT3 and XD1 supercomputers). Today's users have also demonstrated that Lustre scales down as well as it scales up, and runs in production on clusters as small as 4 and as large as 25,000 nodes. The latest version of Lustre is always available from Sun Microsystems, Inc. Public Open Source releases of Lustre are available under the GNU General Public License. These releases are found here, and are used in production supercomputing environments worldwide. To be informed of Lustre releases, subscribe to the lustre-announce mailing list. Lustre development would not have been possible without funding and guidance from many organizations, including several U.S. National Laboratories, early adopters, and product partners.

GlusterFS - GlusterDocumentation
GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86-64 server with SATA-II RAID and Infiniband HBA). Download the latest GlusterFS release from here.

KFS - Kosmos Filesystem
Web-scale applications require a scalable storage infrastructure to process vast amounts of data. Kosmos filesystem is an open-source high performance distributed filesystem designed to meet such an infrastructure need: KFS is implemented in C++ using standard system components such as STL, boost libraries, aio, log4cpp. KFS is integrated with Hadoop and Hypertable. This enables applications bult on those systems to seamlessly use KFS as the underlying data store. KFS is deployed on Solaris and Linux platforms for storing web log data, crawler data, etc. Kosmos filesystem source code is released under the terms of the Apache License Version 2.0.
