Hi all,
i want to know the role of the cluster and VDS in NSX
and what is the difference with cluster HA or DRS
Thank you
both are presequite installation for NSX component. It use for VXLAN transport. VDS are use for containing VXLAN portgroup. There are no different between cluster in HA and DRS. Because it used the same cluster.
here are document for your question = NSX 6 Documentation Center

Thank you very much
Then i can use one cluster ?
You can.
NSX Design guide mentions on the role of Vsphere Clusters between 144-150:
https://www.vmware.com/files/pdf/products/nsx/vmw-nsx-network-virtualization-design-guide.pdf
HA and DRS is important for the Availability and Redundancy of NSX Components as NSX Manager, Controller and Edges since they are Virtual Machines from the perspective of Vsphere Vcenter. These features may be also related about the Cluster design because seperating the NSX Functions into clusters may increase the stability because HA and DRS, as well as antiaffinity rules may be kept on the Cluster Boundaries preventing overlapping of Management, Control and Data Planes of Networking Architecture.
http://www.routetocloud.com/2014/12/nsx-edge-and-drs-rules/
"By default when we deploy a NSX Edge or DLR in active/passive mode, the system takes care of creating a DRS anti-affinity rule and this prevents the active/passive VMs from running in the same ESXi host."
For NSX Controllers DRS Anti-Affinity Rules should be manually created during the Deployment of NSX Controllers. They are not automatically created as Edge and DLR.

Basically the Choice of Clusters may be:
Basically the choice depends on the total Scalability of the Vsphere Environments. For example for Management Cluster in which NSX Manager and Controllers exist, 3 Seperate ESXi hosts are recommended

ahhh thank you very much
another question
i can deploy nsx in physical architecture with 2 lan but there are physically isolated
i have one 4 physical machines pc1 , pc2. pc3, pc4 in management lan connected by a normal switch
and pc3 , pc4 connected with another switch and there is no connection between the switchs
i can do this or i must use routing between the 2 LANS
thank you
Those 2 LAN are different on VLAN / subnet? if yes, you cannot do this and need router to connect between LAN / subnet.
yes one on the 192.168.0.0/24 and the second 192.168,10,0/24
in order to have one subnet for mgt where all the physical machine are and the seconde for services where only 2 physical machines are (in picture )
i don't understand the flow traffic between nsx and my VMS
is it any reference to explain traffic flow ?
thanks
