The computing industry is seeing dramatic growth in the use of "shared nothing" database architectures where each node functions independently of one another and is self-sufficient (Hadoop Distributed File System for example). For the sake of performance, contention among nodes for shared disk resources (SAN and NAS) is one of the things these architectures avoid by dedicating storage resources to each node, i.e. no shared disk.
While these computing architectures are best-known in the context of Web-based applications and development activities, they are no longer confined to the Web. EMC Greenplum, IBM Netezza, and ParAccel are all … Read more
