Product: 3 PAR REMOTE COPY

3PAR Remote Copy is a uniquely simple and efficient replication technology that allows customers to protect and share any application data affordably. Built upon 3PAR Thin Copy technology, Remote Copy lowers the total cost of storage by addressing the cost and complexity of remote replication. Common Uses of 3PAR Remote Copy: Affordable Disaster Recovery: Mirror data cost-effectively across town or across the world. Centralized Archive: Replicate data from multiple 3PAR InServs located in multiple data centers to a centralized data archive location. Resilient Pod Architecture: Mutually replicate tier 1 or 2 data to tier 3 capacity between two InServs (application pods). Remote Data Access: Replicate data to a remote location for sharing of data with remote users.

Product: NetApp MetroCluster Software

NetApp MetroCluster Software Cost-effective is an integrated high-availability storage cluster and site failover capability. NetApp MetroCluster is an integrated high-availability and disaster recovery solution that can reduce system complexity and simplify management while ensuring greater return on investment. MetroCluster uses clustered server technology to replicate data synchronously between sites located miles apart, eliminating data loss in case of a disruption. Simple and powerful recovery process minimizes downtime, with little or no user action required. At one company I worked at they used the NetApp snap mirror feature to replicate data across long distances to multiple datacenters. They had a very fast backbone and it worked well. The issue with NetApp is always one of cost, but if you can afford it, it's a good option.

Product: lighttpd

lighttpd (pronounced "lighty") is a web server which is designed to be secure, fast, standards-compliant, and flexible while being optimized for speed-critical environments. Its low memory footprint (compared to other web servers), light CPU load and its speed goals make lighttpd suitable for servers that are suffering load problems, or for serving static media separately from dynamic content. lighttpd is free software / open source, and is distributed under the BSD license. lighttpd runs on GNU/Linux and other Unix-like operating systems and Microsoft Windows. * Load-balancing FastCGI, SCGI and HTTP-proxy support * chroot support * select()-/poll()-based web server * Support for more efficient event notification schemes like kqueue and epoll * Conditional rewrites (mod_rewrite) * SSL and TLS support, via openSSL. * Authentication against an LDAP server * rrdtool statistics * Rule-based downloading with possibility of a script handling only authentication * Server-side includes support * Flexible virtual hosting * Modules support * Cache Meta Language (currently being replaced by mod_magnet) * Minimal WebDAV support * Servlet (AJP) support (in versions 1.5.x and up) * HTTP compression using mod_compress and the newer mod_deflate ( 1.5.x )

Product: Hibernate Shards

If you want to adopt a shard architecture, but don't want to start from scratch, you may want to consider Hibernate's sharding system. Hibernate Shards is a framework that is designed to encapsulate and minimize this complexity by adding support for horizontal partitioning to Hibernate Core. Hibernate Shards key features: * Standard Hibernate programming model - Hibernate Shards allows you to continue using the Hibernate APIs you know and love: SessionFactory, Session, Criteria, Query. If you already know how to use Hibernate, you already know how to use Hibernate Shards. * Flexible sharding strategies - Distribute data across your shards any way you want. Use one of the default strategies we provide or plug in your own application-specific logic. * Support for virtual shards - Think your sharding strategy is never going to change? Think again. Adding new shards and redistributing your data is one of the toughest operational challenges you will face once you've deployed your shard-aware application. Hibernate Sharding supports virtual shards, a feature designed to simplify the process of resharding your data. * Free/open source - Hibernate Shards is licensed under the LGPL (Lesser GNU Public License)

Lustre cluster file system

Lustre® is a scalable, secure, robust, highly-available cluster file system. It is designed, developed and maintained by Cluster File Systems, 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 CFS'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 Cluster File Systems, 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.
