Deployment Guide

13 Dell EMC Solutions for Microsoft Azure Stack HCI Networking Guide
4.4 Adapter/RDMA/DCB options
This guide is applicable to the following network adapter, RDMA, and DCB combinations:
• QLogic QL41262 – iWARP with or without DCB
• Mellanox ConnectX-4 Lx – RoCEv2 with or without DCB
4.5 VLANs and IP addressing
Table 2 shows the three VLANs used in this deployment. VLAN 1611 uses the 10GbE connections for in-
band management and VM traffic. VLANs 1613 and 1614 are for storage traffic on the 25GbE links.
A gateway is configured using Virtual Router Redundancy Protocol (VRRP) to allow VLAN 1611 traffic to be
routed. A virtual IP address, 172.16.11.254 in this example, is shared by the two leaf switches. Storage traffic
on VLANs 1613 and 1614 is not routed in this deployment.
VLAN 1611 traffic uses a Hyper-V virtual switch (vSwitch), named ProdSwitch in this example, configured for
Switch Embedded Teaming (SET). SET allows between one and eight physical Ethernet network adapters to
be grouped into one or more software-based virtual network adapters.
The two storage VLANs in this deployment use the physical NICs instead of a vSwitch for best performance.
