Local Cluster Configuration - Dell DX6000G User Manual

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.
