Network switch configuration depends on both the network topology and the

customer environment. To ensure proper functioning with default network

parameters and to maximize cluster performance, it is recommended that you

follow the best practices listed below, while configuring both the private and

public networks switches.

•

Disable link aggregation configuration as the DX Object Storage Nodes

bond the system NIC ports in balanced-alb modes.

•

Disable jumbo frames.

•

Disable spanning tree protocol, if the switches are not being trunked.

•

Disable Flow Control.

NOTE:

If switches are trunked, enable spanning tree protocol and port fast on the

data intensive ports.

Contact Dell to customize the network configurations to meet the solution

needs. For more information about configuring the network for the Dell DX

Object Storage Platform, see "Network Topology" in the DX Object Storage

Advanced Administration Guide at support.dell.com/manuals.

Local Cluster Configuration

A basic Dell DX Storage Cluster consists of at least one DX Cluster Services

Node and at least two DX Storage Nodes, along with the necessary Ethernet

infrastructure to connect them. See Figure 2-1.

Within a cluster, DX Storage Nodes communicate with each other through

User Datagram Protocol (UDP) and IP multicast. All nodes within a cluster

must be on the same IP subnet. The DX Cluster Services Node also

participates in UDP and multicast communication and must be located

within the same subnet.

The Layer 3 switch (IP router) used to create the storage cluster subnet must:

•

Restrict UDP and multicast network to the cluster subnet

•

Pass TCP (HTTP) traffic to and from the DX Cluster Services Node and

DX Storage Nodes

NOTE:

You do not require a load-balancer in front of the storage cluster. The

applications communicate directly with the DX Object Storage Platform through

HTTP.
