Shared-nothing and shared-disk are the two most common storage architectures of parallel databases in the past two decades. Both two types of systems have their own merits for different applications. However, there are no much efforts in investigating the integration of these two architectures and exploiting their merits together. In this paper, we propose a novel hybrid storage architecture for large-scale data processing, to leverage the benefits of both shared-nothing and shared-disk

In the proposed hybrid system, we adopt a sharednothing architecture as the hardware layer and leverage a parallel file system as the storage layer to combine the scattered disks on all database nodes. We present an overall design of the new scheme, including data and storage organization, data access modes, and query processing methods. The proposed hybrid scheme can achieve both high I/O performance as a sharednothing system, and high-speed data sharing across all server nodes as a share-disk system. Preliminary experimental results demonstrate that the hybrid scheme is promising and more appropriate for large-scale and data-intensive applications than each of the two individual types of systems.
