To address these problems, today's cluster computing approaches utilize what is commonly called a scale-out or shared nothing
approach to parallel computing.
IBM's bets are now on shared nothing
, despite Oracle's attempts to leverage IBM's mainframe shared-disk clustering heritage.
MPP machines account for 358 machines, up from 327, while traditional vector systems decline from 65 to 58.
In this shared nothing
cluster, each file system is bound to a specific server.
Standard servers can now be used in this way due to the reduction in latency achieved through using the virtual interface architecture compliant ServerNet link, and a better understanding of how to use shared nothing
cluster architectures, according to Compaq.
Unlike every other database, NuoDB is built for the cloud from the ground up on an emergent architecture - a shared nothing
, asynchronous, peer-to-peer approach that is ideal for the cloud, while also delivering the power, reliability and functionality of a traditional database.
