I have two physical hosts without switc and single WAN connection.
host B running many backup software and other tools.
Is it possible to connect two ESX host directly without phisical switch?

Look at the chart, is it possible?

Yes. If you have to connect only two interfaces, you can just run a single network cable between the two interfaces instead of connecting each interface to a switch. With recent network interfaces (any Gigabit, for example), you can use a normal network cable. With older network interfaces that do not have the auto MDI-X feature, you need a crossover cable.
