Scalable architecture for Dell Solutions for Azure Stack HCI

  • The Dell Integrated System for Microsoft 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. TheDell Integrated System for Microsoft Azure Stack HCI consists of two top-of-rack network switches that provide high availability by connecting the nodes to two separate network switches and implementing Switch Embedded Teaming (SET). SET can be configured either as a single interface or configured separately for storage and management traffic along with physical network adapters.

    When using Remote Direct Memory Access over Converged Ethernet (RoCE), configure data center bridging (DCB) in both fully converged and non-converged topologies. 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 must be configured on all nodes and all network switches interconnecting the nodes. The scalable network topology allows for future cluster expansions as business needs grow.
