Use the following steps to configure the physical servers that host the database VMs:
Each ESXi host (R750xs server) has two dual-port Fibre Channel HBAs. The PowerStore 5000T under test has two Fibre Channel front-end I/O modules (one per node). Each I/O module has four 32Gbps ports with a total of eight 32Gbps front-end ports. There are two Connectrix Fibre Channel switches. Each Connectrix switch is its own fabric. For connectivity, each ESXi host was zoned to all eight front-end ports of the PowerStore across the two switches. This configuration should be the default setup. The following figure below shows the SAN zoning configuration.
