VMware NSX-V 6.3: Control Plane Resiliency with CDO Mode
NSX-V 6.3, released last month, introduced many new features. In my last blog post, NSX-V 6.3: Cross-VC NSX Security Enhancements, I discussed several new Cross-VC NSX security features. In this post I’ll discuss another new feature called Controller Disconnected Operation (CDO) mode which provides additional resiliency for the NSX control plane.
The NSX Controllers already offer inherent resiliency for the control plane by design in several ways:
- complete separation of control plane and data plane (even if entire controller cluster is down, data plane keeps forwarding)
- controller cluster of three nodes allows for loss of controller with no disruption to NSX control plane
- vSphere HA provides additional resiliency by recovering the respective NSX controller on another node if host it’s running on fails
For the reasons mentioned above, it’s a rare event and unlikely that communication would be lost with the entire NSX Controller Cluster. In NSX-V 6.3, this control plane resiliency is enhanced even further via CDO mode.
