Dell PowerVault DX6112 Gebruikershandleiding

NOTE: There can be multiple publishers per cluster, but only the active (or primary) Cluster Services Node can be

the active subscriber.

Clusters may be connected by any type of link that can handle the desired traffic volume. This link must be secured to

prevent reading cluster data being passed between clusters.

Cluster data is passed directly between the two DX Cluster Services Nodes.

NOTE: It is not recommended to have direct communication between storage nodes in remote clusters. However,

for high throughput and high availability applications, system administrators who are well versed with managing

RHEL or CentOS systems and who are familiar with IP networking concepts, can directly route to the storage

network.

For more information about multiple cluster configurations, see the

dell.com/support/manuals.

For more information about direct routing between CSN Storage Networks, see the

support.caringo.com.

Application Access To DX Object Storage Platform

Communicating Directly With A Local Cluster

Applications can communicate with a DX Storage Node at any time. The DX Object Storage software automatically

redirects applications to the proper node even if the addressed node is an incorrect node to handle a request. If both

Cluster Services Node and cluster nodes are not responding, you can communicate with the remote cluster by

addressing the remote Cluster Storage Nodes or remote Cluster Services Node directly through the Administrator

Console and the appropriate IP address (for example: http://192.168.3.200:90).
