With networked storage systems, the n-way
storage manager architecture not only does away with the common backplane, it creates an inter-manager correlation process to arbitrate individual storage node anomalies.
MLOR: Unmatched Resilience Distributed storage clusters are designed for Multiple Layers of Resilience (MLOR) across a distributed, N-way storage architecture.
DSC configurations can range from a single interconnect path between two nodes, to dual paths between nodes, to a full N-way mesh configuration.
N-Way Clustering: Multiple distributed controller nodes (as opposed to static storage processors in non-distributed architectures) can be deployed across fiber networks when and where needed (Figure 2).
Storage Clusters improve resilience beyond traditional single-chassis systems by supporting distributed, N-Way availability, continuous storage performance, full server and application infrastructure independence and maximum data integrity in case of site or cluster-wide disasters.
A relatively simple configuration might involve a single interconnect path between two nodes, whereas a full N-way mesh configuration will provide ultimate resiliency.
