Summary: VMware vNetwork Distributed Virtual Switch support in
CloudStack
Key: CLOUDSTACK-657
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-657
Project: CloudStack
Issue Type: New Feature
Security Level: Public (Anyone can view this level - this is the default.)
Components: VMware
Environment: VMware vSphere 5.0/5.1
Reporter: Sateesh Chodapuneedi
Assignee: Sateesh Chodapuneedi
Fix For: 4.1.0
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.
