Scalable Architecture for Dell EMC Solutions for Azure Stack HCI
Introduction Fully-Converged Network Configuration Non-Converged Network Configuration

Introduction

  • The Dell EMC Solutions for Azure Stack HCI scalable architectures support from 2 to 16 nodes in a cluster. The scalable architectures support fully-converged and non-converged network topologies.

    The Dell EMC Solutions for Azure Stack HCI comprises of two top-of-rack network switches which provide high availability by connecting the nodes to two separate network switches and implementing Switch Embedded Teaming (SET). When you are using Remote Direct Memory Access over Converged Ethernet (RoCE) in a fully-converged network topology, you must configure data center bridging (DCB). DCB provides enhancements to the Ethernet protocol, which improves the functionality of data center networks. To take advantage of the Mellanox RoCE network adapters, Priority Flow Control (PFC) and Enhanced Transmission Selection (ETS) are required. PFC and ETS should be configured on all nodes and all network switches interconnecting the nodes.
