Page 5: Introduction
Introduction The Dell DX Object Storage Platform provides a simple and cost effective pool of storage for files whose content do not change often. The object storage platform allows you to: • Expand capacity to meet rapidly changing needs without disrupting services. -
Page 7: Dx Object Storage Platform Overview
DX Object Storage Platform Overview Network Topologies The Dell DX Object Storage Platform network consists of one or more DX Storage Clusters connected by DX Content Router services through a network. There are many possible network topologies depending on the storage network goals. -
Page 8: Local Cluster Configuration
Local Cluster Configuration A basic Dell DX Storage Cluster consists of at least two (three recommended) DX Cluster Services Nodes and at least two (three recommended) DX Storage Nodes, along with the necessary Ethernet infrastructure to connect them. Within a cluster, DX Storage Nodes communicate with each other through User Datagram Protocol (UDP) and IP multicast. -
Page 9: Redundant Dx Cluster Services Nodes
Redundant DX Cluster Services Nodes The Dell DX Storage Cluster supports redundant DX Cluster Services Nodes. In a redundant model, the active DX Cluster Services Node is configured as the primary node and the redundant node is configured as the secondary node. -
Page 10: Subcluster Configuration
Subcluster Configuration A Dell DX Storage Cluster can be split into two or more subclusters. The subclusters are physically part of the same cluster but are recognized as logically separate entities by the DX Object Storage software that provides local area replication. -
