Yan Huang - CSCI5330 Database Implementation – Parallel Database
Examples: Teradata, Tandem, Oracle-n CUBE
Data accessed from local disks (and local memory accesses) do not pass through interconnection network, thereby minimizing the interference of resource sharing.
Shared-nothing multiprocessors can be scaled up to thousands of processors without interference.
Main drawback: cost of communication and non-local disk access; sending data involves software interaction at both ends.
