Abstract
A storage system architecture ensures transactional processing of operations directed to one or more data containers stored on a plurality of volumes distributed across a plurality of nodes interconnected as a cluster. The volumes are organized as a striped volume set (SVS) comprising one meta-data volume configured to store a canonical copy of certain meta-data associated with all data containers stored on the SVS, and one or more data volumes configured to store, at least, data content of those containers. In addition, for each data container stored on the SVS, one volume is designated a container attribute volume and, as such, is configured to store a canonical copy of certain, rapidly-changing attribute meta-data associated with that container. Notably, the invention provides a plurality of SVS operations that enables transactional performance in the cluster using persistent storage and/or systematic accesses to the data/meta-data stored on the SVS volumes.
