DX Cluster File Server Configuration

When you deploy a DX Cluster File Server (CFS), the CFS must have direct

access to the DX Storage Cluster on the private network and the public

network. Gigabit Ethernet or higher is the recommended connection speed

between the CFS server and the DX Storage Cluster Nodes.

The CFS contains six Ethernet ports. In a single server configuration, two

Ethernet ports must be configured to the Public network and four to the DX

Storage Cluster. In a failover configuration, it may be desirable to have a

separate network dedicated to iSCSI traffic. You can configure two Ethernet

ports to the Public Network, two to the iSCSI network, and two to the DX

Storage Cluster. Depending on site requirements, these ports can be

configured for link aggregation protocol (LACP) operating in mode 4, or

adaptive load balancing (ALB) operating in mode 6. Many sites prefer ALB as

it does not require switch configuration. You may use any configuration that

is commonly used in your environment.

A common NTP time source is required for all CFS servers and the DX

Storage Cluster to provide clock synchronization. If you use Active Directory,

the NTP time source must be the same as the domain controller that is used

for handling Active Directory based credentials.

Application Access to DX Object Storage

Platform

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. For many

configurations, it is recommended to create a single name through DNS

which maps to the DX Storage Nodes. A single name allows communication

with the DX Storage Nodes using one domain name. DNS automatically

rotates addressing through the storage nodes. For more information, see the

DX Object Storage Application Guide at support.dell.com/manuals.
