DX Object Storage Platform: Advanced Node Configuration

Sub-Cluster Overview

The DX Object Storage Platform allows a single Storage Cluster to be logically split into two or more

separate entities, or sub-clusters. in order to define storage distribution strategies. While the Storage

Nodes in a sub-cluster are physically part of the same cluster, managed by a common CSN and

communicate on the same IP subnet, they are recognized as logically separate entities by the DX

Object Storage software. The existence of a sub-cluster changes the behavior of the cluster so that DX

Storage attempts to create the greatest logical spread between an object‟s replicas by moving them

into separate sub-clusters. A sub-cluster configuration is primarily used to enable local area

replication. Examples of where sub-clusters are useful are:



Splitting a cluster based on location (data cabinet, building wing, etc.)



Grouping nodes based on common infrastructure (network, power)

DX Cluster

To configure sub-clusters, the node configuration file for each node must be modified to identify the

sub-cluster of which the node is a member. This is done by adding the name/value pairing for the sub-

cluster option in the node configuration file for each storage node. The name is "subcluster" and the

value is the name of the sub-cluster of which the node is a member. Sub-cluster names cannot contain

special characters like quotes and can have a maximum of 16 characters. Below is a sample of a node

configuration file that has been created to assign sub-cluster membership to the node.
