VMware Networking Concepts
=======================
Network :
1) Physical Network : A network of physical machines that are connected so that they can send and recevice data from each other. A EXSi server runs on physical machine. The default maximum no of ports on a standard switch is 120. we can create upto 8 virtual standard switch on a single exsi host.
2) Virtual Network : A network of virtual machines that runs on a single physical machine that are connected logically to each other so that they can send and recevie data from each other.
There are two types of virutal switch in VMware
1) Standard Virtual Switch
2) Distributed Switch
A Vmware vsphere standard virtual switch works like physical switch. It dtect which VM are logically connected to each of its virtual ports.
A Vmware distributed switch act as a single switch across all associated host on datacenter. This allows VM to maintain consitent network configuration as they migrate across multiple host.
Port Group : A port group specficies port configuration options such as bandwidth limitation, vlan tagging and other netowrking function. port group fine how a connection is made thought the switch on the network. typicall a single standard switch is assocaited with one or more port groups.
VMware 2 types of network
=====================
1) Connecting virutal machine to a physical network and to each other
2) Connecting VMKernal services (NFS, iSCSI, vMotion, etc.) to the physical network.
