Verge.IO explains how to set up a two-node cluster on Dell R620 servers using the Verge IO 4.92 ISO. Each server has two Intel Xeon processors, 128GB of memory, two 10G Base T ports, two 1GB ports, one 2TB PCI, and NVMe for VSAN metadata. They will also use four Samsung 850 1TB Pro SSDs for the VSAN tier three for VM workloads. The speaker is configuring the first server by setting up two node controllers for high availability and redundancy, selecting the US time zone, verifying the correct time and date, choosing a name for the cluster, entering the administrator and break glass email address, selecting the ports for network access, setting up the default IP schema for the core network, and configuring the active and external UI switch ports. They also mention that they will use the default MTU for the core network and that they could change it to a lower MTU for the UI access ports.
