Nexus 1000v VSM & Vcenter relationships

Hi all,

I have few questions regarding the relationships between VSM & VCenter.

  • For what reasons do I need the connection between VSM & VCenter beside the initial configuration (vCenter profiles, port-profiles etc..)
  • In case the vCenter is down\SVS connection is down, what can be the impacts on VSM and VEM's (beside pushing configuration changes to vCenter)?
  • Does the VEM & VSM relationships are tied to VSM & VCenter connection?

thanks,

Avi.

Avi -

You need the connection between vCenter and the VSM anytime you want to add or make any changes to the existing port-profiles.  This is how the port-profiles become available to the virtual machines that reside on your ESX hosts.

One problem when the vCenter is down is what you pointed out - configuration changes cannot be pushed

The VEM/VSM relationship is independent of the VSM/vCenter connection.  There are separate VLANs or L3 interfaces that are used to pass information and heartbeats between the VSM and its VEMs.
