The vSphere Standard Switch
The goal of VMware’s Standard Switch is to allow network traffic to flow in any scenario. This could mean that the ESXi host is not connected to a vCenter server at all, which is typically referred to as a “standalone” or “vSphere Hypervisor” install of vSphere. In this case, there’s no higher level of management than the host itself, so the standard level switch needs to be able to function with nothing more than the host telling it what to do.
Before getting too far into how the Standard Switch works, we need to introduce a bit of terminology. When describing switch functions, we often use the terms “control plane” and “data plane.” Control plane traffic and functions can best be thought of as traffic to the
switch, and data plane traffic is traffic through the switch. Management, monitoring, and configuration traffic concerning the switch is control plane traffic. Frames passing from a virtual machine (VM) out to the rest of the world would be data plane traffic. In your typical physical, top-of-rack style switch, control and data planes live within the same piece of equipment. With virtual switches, these functions can be separated.
The control plane of a standard switch resides on the VMware host. That is, any manipulation of the vSwitch configuration, number of ports, and the way that traffic is moved around are all part of the host’s responsibilities. More specifically, it’s the job of the hypervisor kernel (called the VMkernel) to make sure that the vSwitch is configured and operational
As such, even when you cluster a bunch of VMware hosts together, each host is responsible for its own standard vSwitches. In the case of a vCenter failure, every host’s standard vSwitch would still be configurable by connecting the vSphere client directly to the host.
Every Standard vSwitch on a host is responsible for switching frames, which means that the data plane is a host’s responsibility. As data enters the host NICs, which form the uplinks for a standard vSwitch, the VMkernel makes sure that the frames get to the appropriate destination. Sometimes this means that the traffic gets ignored, especially in the case of external traffic that enters the vSwitch with an unknown destination MAC address.

Virtual SAN is a hot topic lately, and for good reason. “Significant technological advancement” and “the standard bearer for a new class of storage solutions that promise to revolutionize how the world buys storage” — that’s what the judges at Interop 2014 in Las Vegas, said when they awarded first place in the Storage category to VMware® Virtual SAN™. But the accolades don’t stop there – Virtual SAN also won the Best of Interop Audience Choice Award.
Why has Virtual SAN turned so many heads?
VMware Virtual SAN delivers a new tier of hypervisor-converged storage. Thanks to its unique architecture and policy based management approach, Virtual SAN radically simplifies storage provisioning and management by putting the application in charge.
