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. 10 DX Object Storage Platform Overview
