Dell CX4 Series - SAN-Attached Cluster

Introduction 13
SAN-Attached Cluster
In a SAN-attached cluster, all nodes are attached to a single storage system or
to multiple storage systems through a SAN using redundant switch fabrics.
SAN-attached clusters are superior to direct-attached clusters in
configuration flexibility, expandability, and performance.
