The following diagram shows the virtual switch design topology that we implemented on the ESXi hosts for the network connectivity that was required for both the Oracle and SQL Server databases. The vmnics in the following diagram are the respective NIC partitions that were created on the CNAs that appear as physical adapters within the ESXi hosts.
Figure 24. Virtual network design in the ESXi hosts
As shown in Figure 14, the virtual network design on the two MX840c database servers consists of:
- VM and management traffic—The VM network and ESXi management traffic uses the default standard virtual switch (vSwitch), which contains two default standard ports groups. The Management Network port group provides the VMkernel port vmk0 to manage the ESXi host from VMware vCenter Server Appliance. The VM Network port group provides the virtual interfaces for in-band management of the database VMs. For high availability and bandwidth, two 5 GbE uplink ports (partition 1) on two separate CNAs (in slots 2A and 2B) in the MX840c ESXi database servers were used for routing the management traffic.
- Public traffic—We created an additional dedicated standard vSwitch for the database public traffic on each of the ESXi database hosts for the Oracle and SQL Server databases. For high bandwidth, availability, and load balance, we used two 15 GbE uplink ports (partition 3) on two separate CNAs (in slots 2A and 2B) in the MX840c ESXi database servers for routing the database public traffic. Within each public vSwitch, we created one standard port group (oraPub-PG and oraSQL-PG, respectively) that provides the virtual network interfaces for the Oracle and SQL Server databases’ public traffic within their respective database VMs.
The Dell EMC customized ESXi 6.7 ISO image that we used contains the qedf FCoE driver for the QLogic QL41262 CNA. This driver ensures that the FCoE partition that we created on the QLogic CNAs for the SAN traffic was automatically recognized as FCoE virtual HBAs (vmhba64 and vmhba65) or storage adapters within the ESXi hosts, as shown in the following figure:
