> Need to integrate the functionality of VMware dvSwitch with CloudStack. This
> enables orchestration of virtual networks in VMware environment over
> distributed virtual switch inside vCenter.
> Background:-
> -----------------
> VMware Distributed Switch is an aggregation of per-host virtual switches
> presented and controlled as a single distributed switch through vCenter
> Server at the Datacenter level. vDS abstracts configuration of individual
> virtual switches and enables centralized provisioning, administration, and
> monitoring.
> vDS is integral component of vCenter. Hence the native vDS support makes
> sense for wider and larger deployments of Cloudstack over vSphere.
> Each Standard vSwitch represents an independent point of configuration that
> needs to be managed and monitored. The management of virtual networks
> required by instances in the cloud is tedious when virtual networks have to
> span across large number of hosts. Using distributed vSwitch (vDS) simplifies
> the configuration and monitoring.
> Being standalone implementations, standard vSwitches do not provide any
> support for virtual machine mobility. So there needed a component to ensure
> that the network configurations on the source and the destination virtual
> switch are consistent and will allow the VM to operate without breaking
> connectivity or network policies. Particularly during migration of VM across
> hosts, the sync up among peers need to be taken care. However in case of
> distributed vSwitch during VMotion, the vCenter server, would update the
> vSwitch modules on the hosts in cluster accordingly.
> Following features are available with a Distributed Switch over and above
> Standard vSwitch of vSphere.
> 1. Shaping of inbound (RX) traffic
> 2. Supports a central unified management interface through vCenter Server
> 3. Supports Private VLANs (PVLANs)
> 4. Provides potential customization of Data and Control Planes
> 5. Increased visibility of inter-virtual machine traffic through Netflow
> 6. Improved monitoring through port mirroring (dvMirror)
> 7. Support for LLDP (Link Layer Discovery Protocol), a vendor-neutral
> protocol.
