Solution with 25GbE/100GbE networking overview

Solution with 25GbE/100GbE networking overview

  • Since the Solution is designed for a production environment, key OpenStack services are made highly available (HA) by clustering the OpenStack controller nodes. The networking is based upon 25GbE bonds for data networks, and the network switches are configured for HA. The Out of Band Management (iDRAC's) network is not HA, and is 1GbE. The 100GbE networking is used in the solution for the user/tenant traffic.

    For basic hardware configuration refer to Bill of Materials.

    Solution 25GbE/100GbE with Ceph rack layout

    The Solution includes three (3) storage nodes, configured in a Red Hat Ceph storage cluster, which is tied into Cinder, Glance, and Nova.

    See Table 15: Solution Admin Host (SAH) Dell EMC PowerEdge R640, Table 16: Controller node Dell EMC PowerEdge R640, Table 17: Compute node Dell EMC PowerEdge R640, and Table 18: Storage node Dell EMC PowerEdge R740xd for hardware configurations. The Solution includes:

    • Node 1: Solution Admin Host with Red Hat OpenStack Director

    Solution 25GbE/100GbE network configuration

    The network for the Dell EMC Ready Architecture for Red Hat OpenStack Platform has been designed to support production-ready servers with a highly available network configuration.

    The node type will determine how the switches are configured for delivering the different networks. Table 11: OpenStack node type to network 802.1q tagging and Table 13: Storage node type to network 802.1q tagging outline the networks to the node types.
